What problem does it solve?

This Skill provides a structured pattern for implementing Circle's Cross-Chain Transfer Protocol (CCTP) to bridge USDC across chains, reducing integration effort, risk, and time-to-value.

Core Features & Use Cases

Attestation & Finality: Integrates Circle Iris attestation, domain mappings, and finality decisions (Fast vs Standard).
Burn-and-Mint Transfers: Supports cross-chain USDC transfers with deterministic messaging and fee handling.
Bridge Kit SDK Integration: Leverages Circle Bridge Kit for simplified estimation, transfers, and monitoring.

Quick Start

Initiate a Fast Transfer of 100 USDC from Ethereum to Solana for recipient 0xRecipient and monitor attestation until mint completes.
