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 quarterly review of technical developments and everything happening in the Fuel Ecosystem. Take a moment to catch up on all the latest news.
We announced that Fuel Labs has partnered with Hyperlane to unlock permissionless interoperability within the Fuel ecosystem. This partnership will pave the way for interchain applications and permissionless bridging with existing blockchains, thereby expanding the reach of the Fuel ecosystem. The integration with Hyperlane will allow Fuel stakeholders to explore unique features such as permissionless deployments of Hyperlane to any chain, permissionless bridging of any asset from any Hyperlane-supported chain with Warp Routes, and interchain applications. This partnership is a significant step toward our vision of creating a more scalable and efficient blockchain ecosystem. Read more about it here.
The Beta version of the Fuel Wallet was released on the Chrome Store. We're excited to see huge interest from our community and beyond, with 30,000+ downloads since launch. The Fuel Wallet allows users to explore DApps on Fuel and manage their crypto assets all in one place. It supports transparent transactions, multi-account management, and easy tracking of assets on the Fuel network. Download it now.
Please note that the app is still in Beta, and we welcome any feedback or issues you may encounter.
This quarter, in our ongoing efforts to foster community engagement and transparency, we have started hosting Twitter Spaces to introduce projects building on Fuel. Here are some of the projects we've featured so far:
PlayEstates: Real Estate fractional ownership on Fuel. Replay.
Stay updated about the latest news from the Fuel Ecosystem projects by following this List, and discover more projects from the Fuel ecosystem with Fuel Build.
We were on the ground in Lisbon to connect in person with hackers and distribute Fuel Swag. We also sponsored bounties for the best Sway developments during the hackathon.
Congratulations to 1st place winner Sway Network (by @swaygangsters), a decentralized, transparent and secure order book built with @SwayLang
We will be attending the Ethereum Community Conference on July 17-20 and be present at various side events to spread the Fuel thesis along the week:
Rollup Day with Altlayer

The Fuel Core is the heart of the protocol that performs the state transition, bridging tokens, transaction validation, and their propagation through the network.
Overview: The Beta 3 network, stress-tested by grantee projects, helped identify performance issues, streamline our deployment pipeline, and overall, equip us with vital insights for a more robust future network.
Impact:
Enhanced performance: The fuel-core underwent numerous optimizations, significantly boosting the network's transaction processing speed.
Deployment pipeline enhancement: The network offered valuable insights into issues regarding our deployment pipeline, debugging processes, and insufficient logging - all pivotal for upcoming releases.
Identified weak points: The network also revealed areas for improvement, initiating corrective measures.
Overview: Integrating Sparse Merkle Tree moved us closer to fraud proofs and light clients. SMT strengthens network security and offers trustless API node interaction. Work is underway to optimize SMT for faster storage interactions.
Impact:
Enhanced security and support: SMT facilitates light client and fraud-proof support, allowing for easy data/asset validation in contract storage/balance.
Greater security: All network participants can now validate contract states and balances, making the network more secure.
Overview: The fuel-core and fuel-vm now support retriable messages, primarily use Nonce instead of MessageId, and have discontinued MessageId in fields.
Impact:
Enhanced security: Retryable messages significantly improve token bridging security and virtually eliminate the possibility of losing bridged funds.
Cost-efficient: By pruning redundant fields, messages are cheaper to support on the network and simpler for users/developers to use.
Overview: Each transaction predicate now includes a used_gas field, indicating the actual gas required for executing the predicate.
Impact:
Parallel execution: Predicate estimation allows for concurrent predicate execution.
Improved accuracy: Predicates no longer consume the block's gas limit, improving transaction selection accuracy.
Cost-efficient: Transactions with empty scripts can now exclude the gas_limit field, reducing transaction costs.
The FuelVM is a virtual machine to execute the bytecode compiled by the Sway.
Overview: Over the past months, significant fuel-vm refactoring has been done to fast-track development, remove unsafe code, increase test coverage, and reduce bug likelihood.
Impact:
Performance improvements: The refactoring and elimination of unsafe code have boosted performance.
Overview: The fuel-vm has shed many limitations and introduced new opcodes to reduce contract size and expand developers' possibilities.
Impact:
General optimization of the FuelVM Opcodes.
Nested calls: The limitation on the number of nested calls has been removed.
Upgradable contracts: Relative jump support allows contract developers to create upgradable contracts.
Native big-number support: 128 & 256 bit integers are now natively supported, allowing for faster math and decreased code size.

Support for configurable constants within the Fuel-TS and Fuel-RS.
Introduced commands to get contract-id and predicate-id in forc.
Added a feature to specify, expected to revert code in forc-test.
Added support for dependencies sourced from the InterPlanetary File System (IPFS).
Enabled git SSH support in forc and allowed nested submodules.
Organized links alphabetically.
The Rust SDK for Fuel can be used for a variety of things, including but not limited to: Deploying, and testing Sway contracts, Launching a local Fuel network, Crafting and signing transactions with hand-crafted scripts or contract calls, Generating type-safe Rust bindings of contract methods.

Many small quality-of-life improvements on the API:
No more .into()s for identity objects (e.g., ContractID).
Better and more crates re-exports.
fuels-types and fuels-core merged.
Trimming utilities to SizedAsciiString.
Other improvements:
Unified type import paths.
low_level_call support.
Gas estimation for script calls.
Better compatibility between Rust and Sway: Support for u128, Bytes and RawSlice.
Separate contract loading and deploying.
