Over four months, ByteSlayer contributed to the pyth-network/pyth-crosschain repository, building robust cross-chain price feed infrastructure spanning Ethereum, Fuel, and TON. They engineered configurable price update parsing, integrated Wormhole-based verification, and aligned contract ABIs with evolving toolchains. Using Rust, Solidity, and Sway, ByteSlayer refactored core data flows for reliability, improved error handling, and expanded test coverage to validate multi-chain updates and fee logic. Their work addressed low-level data alignment, hardened initialization, and streamlined governance and fee management. The resulting system supports secure, maintainable cross-chain price propagation, reflecting deep technical engagement with blockchain protocols and modern smart contract development.
In August 2025, the pyth-crosschain work focused on improving cross-chain reliability, toolchain alignment, and test coverage across Fuel-based execution and TON/Func components. The team delivered alignment with the latest Fuel SDK, hardened initialization and fee-validation flows, fixed low-level data alignment issues, and expanded cross-chain data handling tests. These efforts collectively reduce risk in live cross-chain price feed updates and improve maintainability and future velocity.

July 2025 — pyth-crosschain delivered substantial cross-chain verification and testing improvements that reduce risk and accelerate releases. Key outcomes include VAA verification enhancements with tests validating VAAs from valid sources, a new test framework with core utilities, integration tests for Wormhole and Python contract type parsing, price feeds updates with multi-update support and dynamic update-fee parsing, and the introduction of realistic test data from mock Hermes calls. These changes improve reliability, coverage, and the maintainability of the cross-chain workflow, enabling safer deployments and faster iteration cycles.
