Sway

Sway is a Rust-based, domain specific language for writing smart contracts, created by @fuel_network.

[Sway @SwayLang]

Sway is a language purpose-built for blockchains.

It combines the best of Solidity and Rust, providing a full suite of tools for creating secure, high-performance Dapps.

I will be going live with @SwayLang community call March edition, in an hour.

Stay tuned!

Sway Community Call https://t.co/p2AqycsPA0

[Nazeeh @naz3eh]

I will be hosting the very first @SwayLang community call of the year today.

See y'all at 9 am EST!

[Sway @SwayLang]

Huge shoutout to the compiler team, tooling team and the community for shaping the Sway into what it is today 🙌

[Sway @SwayLang]

With the release of Sway `v0.70.3`, we’ve shipped major updates and compiler enhancements throughout the year, and performance gains cleanly reflect how far we’ve come as an ecosystem.

Let’s look back on our journey over this year.

[Sway @SwayLang]

What’s next?

These benchmarks are just the beginning. We are prioritizing the compile speed gains in 2026.

We’ll soon start surfacing real‑world performance data from Sway projects.

[Sway @SwayLang]

These enhancements refine the Sway developer experience and tighten the compiler foundation for future releases.

Sway `v0.70.3` is now live! 🌴

This release brings targeted improvements across the compiler & tooling that enable faster builds.

[Sway @SwayLang]

What’s new?

→ Patchable registry dependencies
→ Deterministic IR printing
→ `forc‑call` ABI backtracing
→ Introduce `alloc` intrinsic to avoid using `asm`

[Fuel @fuel_network]

Taking a deep second breath on @o2dotapp

⛽️ Boosted markets. Referrals on.

New Sway RFC is live 🌴

RFC #45 introduces a unified approach to error handling in Sway with:

→ Zero-cost defaults on-chain
→ Clear, debuggable errors off-chain
→ Consistent patterns across contracts & libraries

`panic` is now the standard for invariants, with optional typed errors for richer DX

Building a CLOB on Ethereum: 10,000+ lines of Solidity, complex state management, gas optimization hell.

Building a CLOB on Fuel: ~200 lines of Sway, native parallelism, optimal execution.

Architecture matters.

New RFC for Sway is out. It introduces the fuzzing feature to the Sway toolchain.

Fuzzing = automated input generation to explore smart contract edge cases.
