Foundry v1.7.0 is out! Highlights: parallelized stateless fuzzing, invariant optimization mode, Osaka default hardfork, Tempo support upstreamed, MPP for 402-gated RPCs, browser wallet support across forge & cast, immutable releases, and more! $ foundryup --update $ foundryup

alloy 2.0 very soon, and soon after that we're moving onto foundry 2.0 which will allow foundry to evolve into an SDK not dissimilarly from reth sdk which has enabled everyone in the ecosystem to customize and adapt foundry's internals to secure and improve their dev process

RELEASING RETH 2.0! Reth is now faster, smaller, and ready for the future of crypto infrastructure. Gigagas per second has not just been achieved, it's been blown out of the water. We've put in a ton of work in this, and we're incredibly proud to be sharing this with everyone.

We've added MPP / Tempo Wallet support to Foundry - out on latest nightly. - foundryup -n tempo - cast bn -r tempo - cast send erc20 <...> -r tempo --from `tempo wallet whoami --json-output | jq -r .wallet` (to be made less verbose) h/t @onbjerg @gndizzy @zerosnacks

hiring to scale security eng at @tempo. come work with @samczsun, @gakonst, and many others smarter than me on: fuzzing and invariant testing autonomous bug hunting continuous security tooling agentic chaos engineering it's a weird, exciting time to move fast at the frontier.

Foundry has a new release candidate: v1.6.0-rc1! Highlights include: Osaka as default EVM hardfork, parallelized stateless fuzzing, configurable invariant check intervals, improved reentrancy detection and time-based invariant fuzzing. $ foundryup -i v1.6.0-rc1

mind: blown claude foundry fuzzing is very (, very) good, but claude foundry invariant testing is OP!!! same invariant as in the QT, but this time discovered via invariant tests - not targeted fuzzing (ofc oneshotted by claude) instead of trying to guess how the invariant breaks, claude wrote a generic handler that wraps all user-facing, state-changing functions and let the fuzzer do its thing adding another invariant is trivial, just write the invariant itself - no new repro logic needed seems like a step-function upgrade in how protocols are tested huge thanks to the legendary @gndizzy and all the giants building this unbelievable tech

forge-std's v1.14.0 is out, the first release requiring ^0.8.13. github.com/foundry-rs/forge-… v1.13.0 is the last release with partial support for 0.6.*, 0.7.* and 0.8.* up to 0.8.13. github.com/foundry-rs/forge-…

I spoke at Solidity Summit about Solar! 🌞 I gave an overview of the project and some upcoming features 👀 Recording and slides links below

Looking for 3 Rust experts to add to the @tempo team. Once in a career opportunity to build the future of web payments. Criteria I am looking for (at least 1 of the 3): - systems/db background - strong EVM knowledge - specialisation e.g. compiler / security Ashby link below.

Would limiting future versions of `forge-std` to ^0.8.13 compatibility work for you? Older versions of `forge-std` would of course remain available.

Foundry has a new release candidate: v1.5.0-rc1! Highlights include: Solar 🌞 powered AST-seeded fuzzing, improved invariant shrinking, browser wallet support in `cast`, `cast erc20`, distribution of binaries on NPM, and much more! $ foundryup -i v1.5.0-rc1

Still looking for an incredible compiler engineer that is also a Rust expert that will help us fix Solidity with the Solar project. Cash equity. Anyone?

You can just run individual foundry tools with one command and not wait for installing what you don't need s/o @gndizzy for baking this with me on slow fire

As stablecoins grow, so must our devtools. The easiest thing we could do in Foundry was to add some simple ERC20 convenience utilities. From an external contributor! Pick any of our open issues and join the club.

ten million all time downloads on alloy-primitives. stable, intuitive, high performance low-level types for all things Ethereum. incredible work by @DaniPopes & rest of team.

in our effort to improve Foundry's fuzzing capabilities, we've made the dictionary smarter by seeding it with literal values extracted from the source code! in practical terms: the fuzzer now tests high-signal values from the get-go, increasing the probability of finding bugs

Foundry has a new release candidate: v1.4.0-rc3! Highlights include: backtraces, configuration inheritance & multi-chain configuration, forge fmt powered by Solar🌞, enhanced coverage guided fuzzing, custom precompiles & many performance improvements! $ foundryup -i v1.4.0-rc3

Forge LSP is coming very soon, powered by Solar.

`forge fmt` is about to be re-released with `solar` support, which should make formatting faster (so you can do it on every save) & more reliable/customizable -- can i get any tough foundry repos to test?
