# Changelog
## v1.7.1 (2026-05-08)
# Foundry v1.7.1
A patch release on top of [v1.7.0](https://github.com/foundry-rs/foundry/releases/tag/v1.7.0) with cherry-picked correctness fixes for cheatcodes, EVM forking, CLI, `forge`, and `cast`, plus further release-pipeline hardening (updated release version string construction, signed archives & SBOMs).
***
## Cheatcodes
Reverter-address enforcement for CREATE frames, value transfers for payable mock calls, preserved reverts under `expectEmit`, and a fix for the spurious `solc 0.8.35` `error` keyword warning.
Cheatcode fixes (4 PRs)
* fix(cheatcodes): fix solc 0.8.35 `error` keyword warning ([#14509](https://github.com/foundry-rs/foundry/pull/14509)) by @figtracer
* fix(cheatcodes): transfer value for payable mock calls ([#14547](https://github.com/foundry-rs/foundry/pull/14547)) by @srdtrk
* fix(cheatcodes): enforce `expectRevert` reverter address for CREATE frames ([#14615](https://github.com/foundry-rs/foundry/pull/14615)) by @mablr
* fix(cheatcodes): preserve reverts with `expectEmit` ([#14619](https://github.com/foundry-rs/foundry/pull/14619)) by @srdtrk
***
## EVM
Correctness fixes for fork state-snapshot lookups and CREATE address preservation in isolation mode.
EVM fixes (2 PRs)
* fix(evm): query `state_snapshot.storage` in `ForkDbStateSnapshot::storage_ref` ([#14007](https://github.com/foundry-rs/foundry/pull/14007)) by @gutonosa
* fix(evm): preserve `CREATE` address on revert in isolation mode ([#14637](https://github.com/foundry-rs/foundry/pull/14637)) by @mablr
***
## Forge
Tempo's `forge init` template now uses `network = "tempo"` with populated default `rpc_endpoints`, `forge test` ignores `ETH_RPC_URL` for forking, `--fuzz-seed` is finally honored by `forge coverage`, and Tempo creates are encoded as AA calls.
Forge changes (4 PRs)
* feat(forge): use `network = "tempo"` and add `rpc_endpoints` in tempo template ([#14528](https://github.com/foundry-rs/foundry/pull/14528)) by @zerosnacks
* fix(forge): ignore `ETH_RPC_URL` for test forking ([#14555](https://github.com/foundry-rs/foundry/pull/14555)) by @figtracer
* fix(forge): encode Tempo creates as AA calls ([#14585](https://github.com/foundry-rs/foundry/pull/14585)) by @figtracer

## Cast
Consistent `--json` output shapes for the `keychain` subcommands.
Cast fixes (1 PR)
* fix(cast): consistent `--json` output for `keychain` subcommands ([#14590](https://github.com/foundry-rs/foundry/pull/14590)) by @mablr
***
## Config
The `network = "tempo"` key no longer triggers the unknown-key warning, and serialization of `NetworkConfigs` is canonicalized so `forge config` always emits the resolved network.
Config fixes (1 PR)
* fix(config): suppress spurious unknown-key warning for `network` ([#14534](https://github.com/foundry-rs/foundry/pull/14534)) by @zerosnacks
***
## CLI
Fixes the `jsonwebtoken` `CryptoProvider` startup panic by selecting `aws_lc_rs` at compile time, and corrects release version metadata for immutable tags. Also bumps the version to `1.7.1` and tightens `vm.getFoundryVersion()` / `foundryVersionCmp` / `foundryVersionAtLeast` to tolerate the new SemVer build-metadata format.
CLI fixes (2 PRs)
* fix(cli): fix `jsonwebtoken` panic ([#14562](https://github.com/foundry-rs/foundry/pull/14562)) by @pepyakin

***
## CI / Release pipeline
Release archives and Docker images are now signed with `cosign`, per-archive SHA256 + SPDX SBOMs (Syft) are emitted, and Sigstore-signed SLSA provenance attestations are published. The Tempo CI workflow on `release-1.7.1` was realigned with master.
CI changes (3 PRs)
* ci: sign release archives, docker images, and publish SBOMs ([#14563](https://github.com/foundry-rs/foundry/pull/14563)) by @grandizzy
* fix(ci): increase permissions for the enhanced attestation writing ([#14584](https://github.com/foundry-rs/foundry/pull/14584)) by @zerosnacks
* fix(ci): use `PATH_USD` fallback fee token in Mail templates ([#14546](https://github.com/foundry-rs/foundry/pull/14546)) by @mablr
***
## Tests & Tooling
Compiler bumped to `0.8.35` for tests, `forge-std` test fixtures bumped to a newer rev, and clippy lints fixed under newer toolchains so CI is green on this branch.
Tests & tooling changes (3 PRs)
* chore: bump compiler version to 0.8.35 for tests ([#14524](https://github.com/foundry-rs/foundry/pull/14524)) by @zerosnacks
* fix(ext): bump forge-std commit in external integration tests ([#14504](https://github.com/foundry-rs/foundry/pull/14504)) by @zerosnacks
* chore(tests): bump forge-std version ([#14510](https://github.com/foundry-rs/foundry/pull/14510))
* chore(clippy): fix `for_kv_map` and `useless_borrows_in_formatting` ([#14554](https://github.com/foundry-rs/foundry/pull/14554)) by @stevencartavia
***
## Notes on the cherry-pick
* **#14590** was cherry-picked partially: the `{ "remaining": ... }` JSON output object change is included; the new `crates/cast/tests/cli/keychain.rs` test file is **not**, because the `keychain_rl_json_is_object` test depends on Tempo deps newer than this branch.
* The Tempo CI workflow alignment is a backport of #14501, #14537, and #14556 from `master`. The `Check Tempo fork schedule compatibility` step is intentionally omitted — the underlying `tempo::tests::test_fork_schedule_parses_configured_rpcs` test was added in #14485 (Tempo deps bump) which is not part of v1.7.1.

## Full Changelog
[v1.7.0...v1.7.1](https://github.com/foundry-rs/foundry/compare/v1.7.0...v1.7.1)
## v1.7.0 (2026-04-28)
# Foundry v1.7.0
Foundry v1.7.0 brings major improvements to fuzzing and invariant testing, upstreams [Tempo](https://tempo.xyz/) support into the main Foundry toolchain, adds support for HTTP `402`-gated RPC endpoints through MPP, improves browser-wallet and batching workflows across Forge and Cast, and moves Foundry releases to an immutable versioning model.
> v1.7.0 folds in the previously cut `v1.6.0-rc1` release candidate, which never shipped as stable, together with the changes merged since.
## Highlights
### Testing & Fuzzing
* **Parallelized stateless fuzzing** across worker threads with shared corpus ([#12713](https://github.com/foundry-rs/foundry/pull/12713))
* **Invariant `check_interval` config** — deep invariant runs up to **3.6× faster** with `check_interval = 10` ([#13133](https://github.com/foundry-rs/foundry/pull/13133))
* **Invariant optimization mode** — search input sequences that maximize a target value, with realtime best-value tracking and persistence ([#13196](https://github.com/foundry-rs/foundry/pull/13196), [#14147](https://github.com/foundry-rs/foundry/pull/14147), [#14226](https://github.com/foundry-rs/foundry/pull/14226))
* **Improved reentrancy detection** in `call_override` invariant testing ([#13127](https://github.com/foundry-rs/foundry/pull/13127))
* **Time-based invariant fuzzing** via `max_time_delay` / `max_block_delay` configs ([#12616](https://github.com/foundry-rs/foundry/pull/12616))
### Network Updates
* **Osaka is the default EVM hardfork** ([#13112](https://github.com/foundry-rs/foundry/pull/13112)), with precompile decoding for Prague BLS12-381 and Osaka P256VERIFY ([#13094](https://github.com/foundry-rs/foundry/pull/13094))
* **Per-network `hardfork` and `network` keys** in `foundry.toml` ([#14312](https://github.com/foundry-rs/foundry/pull/14312), [#14337](https://github.com/foundry-rs/foundry/pull/14337)), with auto-detection from a fork's chain ID ([#14193](https://github.com/foundry-rs/foundry/pull/14193))
### Tempo
**[Tempo](https://tempo.xyz/)** support has been upstreamed from the standalone [`tempoxyz/tempo-foundry`](https://github.com/tempoxyz/tempo-foundry) fork into `foundry-rs/foundry`. The fork is deprecated; a normal `foundryup` install now ships Tempo support in `forge`, `cast`, `anvil`, and `chisel`.
This is 110 merged PRs spanning execution, RPC, transaction signing and validation, the AA/access-key flow, TIP20 fee tokens, `cast keychain`, `forge create`/`script`/`test`/`coverage` integration, Anvil genesis + pool + tracing, and CI. Notable entry points include:
* `forge init --network tempo` ([#12819](https://github.com/foundry-rs/foundry/pull/12819))
* `cast keychain` for Tempo access keys ([#14166](https://github.com/foundry-rs/foundry/pull/14166), [#14222](https://github.com/foundry-rs/foundry/pull/14222))
* `cast tip20 create` and TIP20 virtual address salt mining ([#14160](https://github.com/foundry-rs/foundry/pull/14160), [#14365](https://github.com/foundry-rs/foundry/pull/14365))
* `--tempo.fee-token` on `forge script` and `cast send` ([#14204](https://github.com/foundry-rs/foundry/pull/14204), [#14184](https://github.com/foundry-rs/foundry/pull/14184))
* Tempo network auto-detection on `anvil --fork-url` ([#14279](https://github.com/foundry-rs/foundry/pull/14279))
Full list in the Tempo section below.
### MPP (Machine Payments Protocol)
Foundry now supports **[MPP](https://mpp.dev/) (Machine Payments Protocol)** for HTTP `402`-gated RPC endpoints. When an RPC provider returns `402`, Foundry signs and pays the challenge with the configured wallet, then retries the request — no API keys or upfront provisioning. A built-in URL mapping covers known providers, and a WebSocket transport handles long-lived subscriptions over paid connections ([#14192](https://github.com/foundry-rs/foundry/pull/14192), [#14404](https://github.com/foundry-rs/foundry/pull/14404), [#14353](https://github.com/foundry-rs/foundry/pull/14353)).
### Forge & Cast
* **Browser wallet support** across `forge script` ([#12952](https://github.com/foundry-rs/foundry/pull/12952)), `forge create` ([#14394](https://github.com/foundry-rs/foundry/pull/14394)), `cast send` ([#13747](https://github.com/foundry-rs/foundry/pull/13747)), and `cast erc20` ([#14395](https://github.com/foundry-rs/foundry/pull/14395)) — sign and broadcast transactions directly from a browser wallet extension instead of provisioning a hot key on disk
* **Realtime `console.log`** in `forge` and `chisel` ([#13321](https://github.com/foundry-rs/foundry/pull/13321)) and **`console.table`** support ([#14338](https://github.com/foundry-rs/foundry/pull/14338))
* `forge inspect linearization` ([#13704](https://github.com/foundry-rs/foundry/pull/13704)) makes it easier to inspect where inherited functions are resolved from
* `forge clone` Sourcify support ([#12900](https://github.com/foundry-rs/foundry/pull/12900))
* `cast batch-send` / `batch-mktx` for native call batching ([#13973](https://github.com/foundry-rs/foundry/pull/13973))
* `cast --curl` flag to print equivalent curl commands ([#13114](https://github.com/foundry-rs/foundry/pull/13114))
### Cheatcodes & Lint
* New cheatcodes: `executeTransaction` ([#13437](https://github.com/foundry-rs/foundry/pull/13437)), `Ed25519` crypto ([#13450](https://github.com/foundry-rs/foundry/pull/13450)), `getRecordedLogsJson` ([#13093](https://github.com/foundry-rs/foundry/pull/13093)), `currentFilePath` ([#13735](https://github.com/foundry-rs/foundry/pull/13735))
* New `forge-lint` rules: incorrect ERC20 interface ([#14428](https://github.com/foundry-rs/foundry/pull/14428)), incorrect ERC721 interface ([#14412](https://github.com/foundry-rs/foundry/pull/14412)), `block-timestamp` ([#14431](https://github.com/foundry-rs/foundry/pull/14431)), and custom errors ([#13126](https://github.com/foundry-rs/foundry/pull/13126)). These catch incorrect ERC20/ERC721 interface implementations, timestamp-dependent logic, and custom-error usage issues.

***
## Breaking / Behavior Changes
* `forge` and `anvil` now default to Osaka ([#13112](https://github.com/foundry-rs/foundry/pull/13112)).
* Fuzz tests now use a random seed by default when none is provided ([#13309](https://github.com/foundry-rs/foundry/pull/13309)).
* `copyStorage` and `setArbitraryStorage` are now marked `Unsafe` ([#13882](https://github.com/foundry-rs/foundry/pull/13882)).
* Compilation now fails on unresolved imports instead of continuing ([#12848](https://github.com/foundry-rs/foundry/pull/12848)).
* `foundry.toml` now supports per-network `hardfork` selection and an explicit `network` key ([#14312](https://github.com/foundry-rs/foundry/pull/14312), [#14337](https://github.com/foundry-rs/foundry/pull/14337)); forked runs can also auto-detect the active network from chain ID ([#14193](https://github.com/foundry-rs/foundry/pull/14193)).
***
## Upgrade Notes
* Run `forge build` after upgrading. Compilation now fails on unresolved imports instead of silently continuing ([#12848](https://github.com/foundry-rs/foundry/pull/12848)) — projects with stale remappings or dead imports that previously compiled may now error. Fix by correcting the remapping or removing the dead import.
* If you rely on reproducible fuzz runs, pin a fuzz seed explicitly. v1.7.0 now generates a random seed when none is provided ([#13309](https://github.com/foundry-rs/foundry/pull/13309)).
* If you rely on `copyStorage` or `setArbitraryStorage`, update tests and helpers to account for these cheatcodes now being marked `Unsafe` ([#13882](https://github.com/foundry-rs/foundry/pull/13882)).
* If you previously configured a single `hardfork`, migrate to the new `network` / per-network `hardfork` settings ([#14312](https://github.com/foundry-rs/foundry/pull/14312), [#14337](https://github.com/foundry-rs/foundry/pull/14337)). Forked runs can also infer the active network from chain ID ([#14193](https://github.com/foundry-rs/foundry/pull/14193)).
***
## Testing & Fuzzing
### Parallelized Stateless Fuzzing ([#12713](https://github.com/foundry-rs/foundry/pull/12713))
Stateless fuzz tests now run across multiple worker threads, significantly improving execution speed on multi-core machines. Each worker maintains its own corpus and periodically syncs with a master corpus, enabling efficient parallel exploration while sharing discovered coverage. Workers automatically distribute runs evenly and aggregate results after completion. Stateful (invariant) tests are not parallelized in this release.
### Invariant `check_interval` Config ([#13133](https://github.com/foundry-rs/foundry/pull/13133))
A new `check_interval` config option controls how often invariants are asserted during deep runs:
| Value | Behavior |
|-------|----------|
| `0` | Only assert on the last call of each run (fastest) |
| `1` (default) | Assert after every call (current behavior, most precise) |
| `N` | Assert every N calls AND always on the last call |
```toml
[invariant]
depth = 1000
check_interval = 10
```
**Benchmark**: With `check_interval = 10`, deep invariant runs (1×1000 depth) are **3.6× faster** (15.09s → 4.17s).
> Caveat: with `check_interval > 1`, an invariant that is violated and then restored between checks can be missed.
### Invariant Optimization Mode ([#13196](https://github.com/foundry-rs/foundry/pull/13196), [#14147](https://github.com/foundry-rs/foundry/pull/14147), [#14226](https://github.com/foundry-rs/foundry/pull/14226))
Define an `invariant_*` function that returns `int256` and the fuzzer searches for the call sequence that maximizes it. Useful for finding worst-case rounding errors, drained balances, max slippage, etc.
```solidity
function invariant_optimize_maxRoundingError() external view returns (int256) {
return int256(pool.totalShares()) - int256(pool.expectedShares());
}
```
The best value and shrunk reproducer are tracked in realtime and persisted across runs.
### Improved Reentrancy Detection with `call_override` ([#13127](https://github.com/foundry-rs/foundry/pull/13127))
The `call_override` invariant testing feature now correctly detects ETH transfer reentrancy vulnerabilities, including:
* **EtherStore pattern**: classic DAO-style reentrancy where a handler sends ETH out and the attacker reenters
* **Rari Capital pattern**: protocol-level reentrancy where external protocols send ETH to handlers
Validated against a reproduction of the April 2022 Rari Capital hack.
### Time-based Invariant Fuzzing ([#12616](https://github.com/foundry-rs/foundry/pull/12616))
New `max_time_delay` and `max_block_delay` invariant configs enable fuzzing of block timestamp and block number on consecutive transactions. This helps discover time-dependent vulnerabilities that only manifest under specific block timing conditions. Counterexamples now display the `vm.warp()` and `vm.roll()` calls needed to reproduce failures.
### Other Testing Improvements
Smaller polish across the fuzzing and invariant pipeline: clearer reporting of assertion failures, faster feedback on broken invariants, more reliable counterexample replay, and broader fuzz coverage including native Rust code.
Other testing improvements (5 PRs)
* Assertion failures (`assert()`, `vm.assert*`, panics) are now reported as invariant failures during campaigns instead of being silently discarded with reverts ([#14275](https://github.com/foundry-rs/foundry/pull/14275))
* Broken invariants are logged as soon as they are found ([#14433](https://github.com/foundry-rs/foundry/pull/14433))
* Counterexample validation now uses settings rather than bytecode ([#13219](https://github.com/foundry-rs/foundry/pull/13219))
* SanitizerCoverage support for coverage-guided fuzzing of native Rust code ([#14339](https://github.com/foundry-rs/foundry/pull/14339))
* Address mutation variant added to fuzz dictionary selection ([#13090](https://github.com/foundry-rs/foundry/pull/13090))

## Network Updates
### Multi-Network Execution
The entire `foundry-evm` and `anvil` stack has been genericized over `Network`, `Spec`, `Block`, and `EvmFactory`, allowing one Foundry binary to drive **Ethereum, Optimism, and Tempo** through the same execution path. See the Internals section below for the full list of refactor PRs.
Notable consequences:
* A new `network` key in `foundry.toml` and per-network `hardfork` selection ([#14337](https://github.com/foundry-rs/foundry/pull/14337), [#14312](https://github.com/foundry-rs/foundry/pull/14312))
* Auto-detection of the active network from a fork's chain ID ([#14193](https://github.com/foundry-rs/foundry/pull/14193))
```toml
[profile.default]
tempo = true # marks Tempo as the active non-Ethereum network
hardfork = "tempo:T3" # namespaced hardfork; bare names like "osaka" still work for Ethereum
```
Hardforks can also be set per-test via inline config:
```solidity
/// forge-config: default.hardfork = "tempo:T3"
function test_something() public { ... }
```
`forge init --network tempo` writes the `tempo = true` key for you. Forked runs (`forge test --fork-url ...`) infer the network from chain ID, so the network key is only required when there is no fork to infer from.
### Other Chain Support
Per-chain quirks landed across XDC, SKALE, Polkadot, Optimism, Monad, MegaETH, Arbitrum, and Etherlink — covering RPC gas estimation, base-fee parameters, system-tx senders, and fork block pinning.

## Improved Integration
### Immutable Releases ([#14445](https://github.com/foundry-rs/foundry/pull/14445))
Foundry releases are now fully immutable. The mutable `nightly`, `stable`, and `rc` Git tags are gone — only semver tags (`v*.*.*`) and per-commit `nightly-{SHA}` releases exist.
For `foundryup` users:
* `latest` is the new default channel (alias: `stable`).
* `nightly` resolves to the most recent `nightly-{SHA}` prerelease.
* Pinning to a specific build (`foundryup -i v1.7.0` or `foundryup -i nightly-abc1234`) continues to work and is now permanently reproducible.
Docker tags follow the same model: version releases get `:v1.7.0`, `:v1.7`, `:v1`; nightlies are tagged as `nightly-{SHA}`.
### Foundryup Rust Rewrite (Experimental)
This release is accompanied by a new Rust rewrite of [`foundryup`](https://github.com/foundry-rs/foundryup) for better maintainability, testing, and compatibility. The rewrite is still experimental; the existing installer remains the recommended path for now. To try the new `foundryup`:
```bash
curl -L https://raw.githubusercontent.com/foundry-rs/foundryup/HEAD/foundryup-init.sh | bash
foundryup
```
### Foundry-toolchain TypeScript Rewrite
The [`foundry-toolchain`](https://github.com/foundry-rs/foundry-toolchain) GitHub Action has been completely rewritten in TypeScript for improved maintainability and reliability. See the [v1.7.0 release](https://github.com/foundry-rs/foundry-toolchain/releases/tag/v1.7.0).
### `foundry-core`
The previously standalone `foundry-fork-db`, `foundry-compilers`, `foundry-block-explorers` (+ `foundry-blob-explorers`), and `foundry-wallets` crates are now maintained under [`foundry-rs/foundry-core`](https://github.com/foundry-rs/foundry-core) and consumed as published crates ([#14348](https://github.com/foundry-rs/foundry/pull/14348), [#14427](https://github.com/foundry-rs/foundry/pull/14427), [#14443](https://github.com/foundry-rs/foundry/pull/14443)).
### Other Integration Changes
Hardening of the publishing pipeline: trusted OIDC for npm and proper semver floating tags for Docker.
Other integration changes (2 PRs)
* OIDC trusted publishing for npm, removing the long-lived `NPM_TOKEN` ([#14249](https://github.com/foundry-rs/foundry/pull/14249))
* Docker semver major/minor floating tags on release ([#13182](https://github.com/foundry-rs/foundry/pull/13182))

## Internals: generic `Network` / EVM refactor
Mostly relevant to contributors and downstream integrators. The largest internal refactor since the `revm`/`alloy` migration: the entire `foundry-evm`, `cheatcodes`, `script`, `cast`, and `anvil` stacks were genericized over `Network`, `Spec`, `Block`, and `EvmFactory`, enabling a single Foundry binary to drive Ethereum, Optimism, and Tempo through the same code paths.
This work spans **~260 PRs**, primarily by @mablr, @figtracer, and @stevencartavia, broken down roughly as:
* `foundry-evm` core: ~130 PRs (`Backend`, `Executor`, `DatabaseExt`, `InspectorStack`, `FoundryEvmFactory`, `FoundryContextExt`, `NestedEvm`, etc. all generic; `Env` abstraction removed; `EthFoundryEvmFactory` and `OpEvmNetwork` introduced)
* Cheatcodes generic refactor: ~30 PRs (`Cheatcodes`, `CheatcodesExecutor`, `BroadcastableTransaction` made `Network`/`Evm`/`Spec`/`Block`-generic)
* Anvil generic refactor: ~50 PRs (`Backend`, `EthApi`, `Pool`, `Storage`, `Signer`, `BlockExecutor`, fee history, beacon handlers, etc. all generic over `Network`)
* Additional supporting changes: ~50 PRs (trait-method usage instead of direct field access, dead-code removal, `revm` v34→v38 bump, alloy 2.0.x bumps)
Full PR list: [v1.5.1...v1.7.0 changelog](https://github.com/foundry-rs/foundry/compare/v1.5.1...v1.7.0).
