Fe is a Rust-like language for the EVM, with explicit effects, message-passing contracts, and an integrated toolchain.

Fe 26.5 is here, our biggest release yet!
A simpler borrowing model, closures, tuple structs and typed ETH amounts. Storage speaks Solidity, the stdlib grows a lot, and the experimental native backend ships in the release binaries.

Fe de verdad le saca el jugo a ethereum. Muy bonito y util lenguaje. Qué cosas interesantes podrás escribir encima de él. Y encima de cuantas cosas bonitas está hecho.
Denle una probadita e inscríbanse!
Announcing the Fe Builders Challenge: three weeks to build something with Fe and compete for $5,000 in prizes.
The build window runs November 3 to 24. Solo or team, fully online, AI assistance welcome.

Projects are judged on technical quality (30%), Fe-specific value (25%), originality (20%), usefulness (15%), and documentation and demo (10%).
New to Fe? You're welcome here. A working prototype is enough, and social reach doesn't affect your score.
The prize pool is funded by @argotorg: $2,500, $1,500, and $1,000 for the top three projects.
Register your project by November 17 and read the full announcement:

As promised: the release binaries now include the experimental native backend.
We use it ourselves: our release notes come from eisenbote, a replacement for the popular Python-based towncrier, written in Fe and compiled natively.
Big native improvements are coming next.

Under the hood: smaller bytecode, cheaper loops and a parser that is about twice as fast.
There is much more in this release. Read the full announcement and give Fe 26.5 a try:

CREATE2 addresses you can compute ahead of time.
create2 now embeds exactly the B.bin from fe build, so an address computed off-chain matches the deployed one. Previously they could differ.
New std::evm::clones deploys ERC-1167 minimal proxies and predicts their addresses.
One language for contracts and the tools around them?
Fe can now build native programs for x86-64 Linux and AArch64 macOS, with basic host I/O and process arguments.
Experimental: build fe from source with the cranelift feature. Release binaries get it in 26.5.
Under the hood: more precise borrow checking, better Solidity ABI compatibility and leaner bytecode. In our ERC-20 benchmark, name() drops from 3,861 to 857 gas.
Install 26.4.1 and read the full release notes:
blog.fe-lang.org/posts/relea…
Fe 26.4 is here! Grab 26.4.1, which fixes a borrow-checking regression found right after 26.4.0.
Inside: more building blocks for DeFi, better Solidity interop, a more capable compiler, and a first experimental step toward native programs.
Highlights 👇
Token transfers come with quirks. Your contract should decide how to handle them.
New non-reverting ERC-20 helpers tell you whether a call succeeded, reverted, returned failure or hit an address without code.
ERC-721 and ERC-1155 get non-reverting transfer helpers too.
