About

Circle CCTP utilities for Rust — depositForBurn encoding and Iris attestation verification.

SKILL.md

cctp-utils

cctp-utils implements the two hard parts of Circle's Cross-Chain Transfer Protocol: ABI-encoding depositForBurn calls and fetching/verifying attestations from the Circle Iris API. Use it to move USDC across chains without a bridge token.

When to use

Implementing native USDC bridging in Rust, verifying Iris attestations, or building CCTP-aware routing.

Install

cargo add cctp-utils
