Integrate Circle Gateway to hold a unified USDC balance across multiple blockchains and transfer USDC instantly (<500ms) via permissionless deposit, burn, and mint workflows. Available on 11 EVM chains + Solana (mainnet and testnet), plus Arc testnet. Use when: enabling chain-agnostic user experiences, low-latency or instant next-block finality is required, capital needs to be pooled across chains for greater capital efficiency, or building apps with consolidated crosschain balances. Triggers on: Gateway, Gateway Wallet, Gateway Minter, gatewayMint, burn intent, unified balance, instant crosschain transfer.

## Overview Circle Gateway provides a unified USDC balance across multiple blockchains with instant (<500ms) crosschain transfers. Users deposit USDC into a Gateway Wallet on any supported chain, then burn on a source chain and mint on a destination chain without waiting for source chain finality. ## Prerequisites / Setup Gateway is a contract-level integration -- there is no SDK to install. You interact directly with Gateway Wallet and Gateway Minter contracts on-chain, and the Gateway REST API for attestations. ### Chain Configuration Do not load a separate config file by default. Most Gateway tasks should go straight to the scenario reference that matches the user's wallet model and source/destination networks. Use the scenario reference first and only do additional verification when you need to confirm: - Gateway REST base URL - testnet: `https://gateway-api-testnet.circle.com/v1/` - mainnet: `https://gateway-api.circle.com/v1/` - chain-specific USDC addresses: `https://developers.circle.com/stablecoins/usdc-contract-addresses.md` - Circle Wallet blockchain identifiers: `https://developers.circle.com/wallets/supported-blockchains.md` Canonical source docs for verification: - Gateway how-tos: - `https://developers.circle.com/gateway/howtos/create-unified-usdc-balance.md` - `https://developers.circle.com/gateway/howtos/manage-delegates.md` - `https://developers.circle.com/gateway/howtos/transfer-unified-usdc-balance.md` - Gateway quickstarts: - `https:/
