Circle Gateway
Integrates Circle Gateway to manage unified USDC balances and execute sub-second crosschain transfers across EVM chains and Solana.
Circle Gateway enables developers to integrate Circle's unified balance protocol, allowing users to pool USDC liquidity across 11+ EVM networks, Solana, and Arc. Instead of waiting for standard crosschain bridge finality, this skill facilitates instant transfers (<500ms) through permissionless deposit, burn, and mint workflows. It provides complete integration patterns across self-managed wallets, injected browser providers (EIP-1193), and Circle Developer-Controlled Wallets, complete with strict signing requirements (EIP-712 and Ed25519) and token balance query utilities.
