Fuel LabsIntroducing Fuel Season 1 (FS-1) and Phase 2 Genesis Drop
Today marks the conclusion of Phase 2 and with it the Fuel Points Program. We want to thank all participants who helped bootstrap Ignition, and now turn our focus to building Fuel into a fully integrated liquidity hub. As we mark the end of the Fuel Points program, we are excited to unveil two initiatives: Phase 2 of the Genesis Drop and the start of Fuel Season 1 (FS-1).Genesis Drop: Phase 2 - 150,000,000 FUEL1.5% of FUEL total supply.Rewards for participation in Phase 2 of the Points Progra...
Fuel LabsAnnouncing Phase 2 of the Fuel Points Program
We are excited to announce the final phase in the Fuel Points Program, now live with Fuel Ignition. With Phase 2, you can continue earning points while supporting the growth of the Fuel ecosystem. With Phase 2 of Fuel Points, we’re ensuring that the network grows in a way that is positive sum for points program participants, the Fuel ecosystem projects and the broader Fuel community. Qualifying users can participate in the program, while earning rewards for meaningfully engaging with the ecos...
Fuel LabsSway: The Next-Generation Language for Smart Contracts
As blockchain applications become more complex, there is a strong need for safe and smart contract languages. Many platforms today rely on languages and virtual machines (VMs) that weren't originally designed to handle the unique constraints and requirements of blockchain execution. It’s no secret that the architectural decisions made in 2014 for Solidity and the EVM now show clear signs of age. Among these is their susceptibility to vulnerabilities that make writing secure Ethereum smar...

Welcome to Inside Fuel, our review of technical developments and everything happening on the Fuel Network. Take a moment to catch up on all the latest news.
Building the fastest modular execution layer would not be possible without an incredible contributor team. Here are the newest additions to the team this month:
According to the Rust In Blockchain monthly review, Fuel is one of the most active Rust-based projects this November with 247 merged PRs, 165 closed issues, and 137 open issues. We are ranked fourth right behind Parity, Sui, and Solana.
Nick Dodson took part in the Devs Do Something podcast to talk about Sway and the FuelVM.
He also joined Blockchain Capital with John Adler to explain Fuel's vision of scaling Ethereum with the power of the fastest modular execution layer.
Cami Ramos joined the Espacio Crypto podcast (in Spanish) to talk about her experience in growing the Fuel developer community.
We hosted the second episode of Sway Day, a monthly discussion about all-things Sway. This time, the main topic was Predicates - Why and how you should use them. where we had the chance to have the founders of one of our granted projects, Poolshark, a DEX with a Price-Time-Priority feature, building on Fuel.
Read the TL;DR and listen to the replay here 👇:
We attended and sponsored the first edition of EthSF in the Bay area, a 3 day-long hackathon during which hackers teamed up to build DApps this November. Read more about the winning projects here.
Introduction of testnet-specific toolchains: beta-1 and beta-2 toolchains. Installable through fuelup toolchain install beta-2 for example;
forc-doc and fuel-indexer are now packaged in a default toolchain;
fuelup has completions thanks to an external contributor @0xYYY;
fuelup update can be used as a shorthand for fuelup toolchain install latest|nightly;
So far, the following libraries are available to use:
Binary Merkle Proof is used to verify Binary Merkle Trees computed off-chain.
Non-Fungible Token (NFT) is a token library which provides unqiue collectibles, identified and differentiated by token IDs.
String is an interface to implement dynamic length strings that are UTF-8 encoded.
Signed Integers is an interface to implement signed integers.
Unsigned Fixed Point 64 bit is an interface to implement fixed-point 64 bit numbers.
New English Auction application. The auction allows sellers to put up assets that they would like to sell based on an initial price and a reserve price. Users bid until the reserve price is met or the time expires;
New Name Registry application which allows users to own a human-readable name that can be used to transfer assets. This means that a user does not have to use the hex format of random characters; instead, they can use a memorable word/name to transfer;
New Over-The-Counter (OTC) Swap Predicate application demonstrates a proof-of-concept whereby coins to be swapped are locked behind predicates. Anyone can spend these coins, as long as their transaction sends a certain quantity of coins back to a provided address - thereby completing a stateless atomic swap between two parties.
Note: This minimal example could serve as the basis for an entire order book exchange, where orders are circulated off-chain, and settled solely through the funding and spending of predicates. This design would be orders of magnitude more performant than a storage-backed smart contract implementation.
New Automated Market Maker (AMM) application. It allows users to swap assets via liquidity pools;
Sway is a language for writing smart contracts for the Fuel Virtual Machine (FuelVM), a blazing-fast, blockchain-optimized VM designed for the Fuel blockchain. It is heavily inspired by Rust and aims to bring modern language development and performance to the blockchain ecosystem. Start learning the Sway language today with the Sway Book and the FuelVM Bootcamp.

VM fixes for MROO & LB;
Better debugability through parsed readable revert errors;
Predicate data encoder;
Block time manipulation, useful for testing;

Fuel is the fastest execution layer for the modular blockchain stack. Powerful and sleek, the technology enables parallel transaction execution, empowering developers with the highest flexible throughput and maximum security required to scale. Developers choose the FuelVM for its superior developer experience and the ability to go beyond the limitations of the EVM.
