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.

[Tempo @tempo]

Tempo Mainnet is live! Starting today, anyone can build on Tempo through our public RPC endpoints.

Alongside mainnet, we’re introducing the Machine Payments Protocol, an open standard for machine payments.

Introducing the Porto Developer Preview!

What if passwords did not exist?

What if the web was built natively for payments?

Porto is the open-source Typescript library we've built @ithacaxyz that gives accounts the superpowers to answer these questions.

🚨 Action required: After >3yrs of heads-down development, Foundry is en route to our first stable release! Upgrade your installation of Foundryup! 🚨

2025 is looking to be an amazing year with faster and more secure EVM smart contracts!

Foundry is a critical part of the EVM development stack, empowering developers through their end to end development lifecycle, from quick builds to deep tests and rich debugging workflows.

More importantly, for the EVM to win, Foundry must remain a reliable building block for developers. For that, we must graduate to having stable releases, so we encourage all developers to upgrade their `foundryup` installations.

Upgrading is really simple, just run: `curl -L https://t.co/myqScjYfu3 | bash`.

❗Why upgrade?

Upgrading ensures your `foundryup` defaults to updating to the latest stable release instead of the latest nightly build. That build is hosted on Github under the `stable` tag: https://t.co/d5SBm6vmQo.

In the coming weeks, we'll be shipping our last few breaking changes to Foundry (e.g., turning off the optimizer by default, which was recently shipped). If you do not upgrade, you will continue to receive nightly builds by default, which may contain these breaking changes.

✨ Prefer nightly builds?

You are still able to receive the latest nightly builds by running `foundryup --install nightly`

Be cautious — nightly builds may include breaking changes that are difficult to debug without context.

🔄 Switching between versions?

Easily manage your installations with: `foundryup --use <version>`

e.g. `foundryup --use nightly`, `foundryup --use stable`

⚙️ And the CI?

The foundry-toolchain GitHub Action will use the latest stable release unless you specify the version to be different: https://t.co/hURV4C4633, via the `version` tag.

Huge kudos to legends @gndizzy @zerosnacks @YashAtreya @DaniPopes who have taken over the Foundry torch in the last year.

[gretzke.eth @gretzke]

Foundry now allows you to set up multiple profiles that are compiled simultaneously. This allows us to compile us important contracts with IR and optimize them while compiling unit tests without IR and keeping compile times short.

Introducing Solar ☀️

Solar is an implementation of the Solidity compiler, in Rust; licensed Apache/MIT.

Solar is built for the future of smart contracts, in a world where developers seek customization, and assume great performance, safety, and developer experience.

[Matthias Seitz @mattsse_]

ICYMI, this exists.
unlocks 7702 support for local testing:

Crypto needs to move faster.

We started @Ithacaxyz to accelerate the frontier, &amp; have raised $20M from @paradigm.

We’ve been collaborating with the developer community on some of crypto's hardest problems. Small teams = big impact. The future of crypto will be built together.

[Arsenii Kulikov @klkvrr]

@msolomon44 @noah_eth @0xCygaar yeah, we've also added forge bind-json which automatically generates helpers for serialization/deserialization of arbitrary structs from JSON, it should work for pretty much any struct

though it's not really documented atm

🚨 Releasing Reth 1.0 🚨

After almost two years of development and a successful audit by Sigma Prime, we are finally releasing Reth 1.0, the first “prod-ready” release of our blazing-fast Ethereum execution client. We invite RPC providers and stakers to run Reth.

More below.

[Arsenii Kulikov @klkvrr]

@muspro__dev @0xjuaan forge already has a built-in debugger: https://t.co/MS4ddEJuxi

[Arsenii Kulikov @klkvrr]

@0xjuaan you can do that already!

[Arsenii Kulikov @klkvrr]

This is still experimental and there is still a lot of work left to make UX with Vyper as smooth as with Solidity,

Check out our tracking issue for more context - https://t.co/hZqjsTlLOW

[Arsenii Kulikov @klkvrr]

Vyper support is live in Foundry!

You can now build Vyper contracts, they are made available in your Forge tests via the deployCode cheatcode

🚨 Shadow Logs Reth Execution Extension 🚨

The @shadowxyz team has listened to the community and shipped a Reth ExEx for Shadow Logs.

This gives any Reth node operator the ability to generate and query Shadow logs over JSON-RPC!

See the blogpost in the quoted tweet for more.
