Circle USDC Integration
Manages native USDC stablecoin operations including balance checks, transfers, and token approvals across EVM chains and Solana.
Circle USDC Integration equips Claude Code with protocol-accurate guidance for interacting with Circle's native USDC stablecoin across EVM networks (Ethereum, Base, Arbitrum, Polygon, Arc) and Solana. It enforces crucial web3 standards—such as strictly applying 6 decimals instead of 18, handling Solana Associated Token Accounts (ATAs), validating native token contract addresses, and segregating safe read operations from user-confirmed write transactions—to streamline stablecoin payment and transfer development.
