Foundry v1.3.0

This release includes support for forge lint, time-based campaigns and coverage-guided fuzzing for invariant tests, table tests, fork test improvements for Reth clients, and new EIP-712 features. Foundry v1.3.0 is built on top of the latest revm v27 Foundry v1.3.0 is built on top of the latest revm v27 and comes with an improved foundryup installer.

⚠️ It is highly recommended to update to latest version of foundryup, which avoids unnecessary downloads and verifies hashes of downloaded binaries upon install. You can update your installation by running: foundryup --update.

Performance Improvements

• This release includes an updated revm (#11079) and an optimized inspector stack (#11077), which enhances Forge test performance by up to 21.50% compared to previous versions

Forge Test

Forge Fuzz Test

• Forked tests using the Reth client are now faster thanks to the eth_getAccountInfo API (#10496 #10838), reducing account data fetching from three requests to one. Foundry detects if eth_getAccountInfo is available and falls back to the legacy method otherwise.
  Example: Running forge test --mt statefulFuzz_curve_test on spark-alm-controller showed over 5 seconds in test time savings.

Forge Lint

As of v1.3.0, Forge ships with a built-in linter (#10405) that analyzes Solidity code for style, correctness, and best practices.

• Lint rules are configurable in the [lint] section of foundry.toml and via inline comment directives.
• Lints can be customized by severity or specific rule identifiers.
• By default, linting runs during forge build. To disable it, set lint_on_build = false.
• For more details please refer to foundry docs:
  Supported lints
  Linter configuration docs
  How to contribute a lint rule

Invariant Test Improvements

Time-Based Campaigns

Previously, invariant tests were limited by a fixed number of runs (default: 256, max: 4294967295).
Now you can run them for a specific time duration by setting the timeout value (in seconds) in the [invariant] section of foundry.toml (#10190).

The test progress bar shows the number of runs and the end time.

test/GuidedTest.t.sol:CounterTest
 → invariant_Puzzle5: [4360] Runs, ends at 11:03:28 2025-06-03 UTC
 → invariant_Puzzle3: [8784] Runs, ends at 14:50:08 2025-06-04 UTC
 → invariant_Puzzle6: [77762] Runs, ends at 05:56:48 2025-06-09 UTC
 → invariant_Puzzle2: [8739] Runs, ends at 12:50:08 2025-06-02 UTC

Coverage-Guided Fuzzing

Enable this mode by setting a path to corpus_dir in your invariant config (#10190).
The coverage-Guided fuzzing mode targets a corpus_min_size by mutating entries a number of times (default: 5), favoring those likely to uncover new paths.

Supported mutations:

• splice: Combines two sequences
• interleave: Weaves two sequences together
• prefix: Overwrites the beginning of a sequence
• suffix: Overwrites the end of a sequence
• mutate args: Randomizes some call arguments

Additional notes:

• Entries that generate new coverage are saved to disk (default: .gz; set corpus_gzip = false to save as JSON).
• On reruns, the saved corpus is loaded and reused.
• Metadata (as JSON) is persisted for evicted corpus entries. This includes a unique ID, mutation count, and coverage improvements.
• The fuzzing progress bar displays metrics for cumulative edges and features, corpus count and number of favored entries.

test/forge/invariant/StaticInvariantTest.sol:StaticInvariantTest
 → invariantHealthy: [60/2000] Runs
  - cumulative edges seen: 41
  - cumulative features seen: 6
  - corpus count: 15
  - favored items: 14

For more details please refer to invariant docs.

Table Tests

Foundry v1.3.0 comes with support for table testing (#10775), which enables the definition of a dataset (the "table") and the execution of a test function for each entry in that dataset. This approach helps ensure that certain combinations of inputs and conditions are tested.
For more details please refer to table testing foundry docs.

Improved EIP-712 support

Foundry v1.3.0 comes with additional utilities (commands and new cheatcodes) to make it easy and reliable to work with EIP-712 signatures (#10510).
For more details please refer to EIP-712 foundry guide.
