Build an application that enables multichain USDC payments and payouts using Fast Transfers from CCTP V2. * Please note that CCTP V2 currently supports Avalanche, Arbitrum, Base, Ethereum, Linea, Sei, Sonic * Bonus points if CCTP V2 hooks are used Example Use Cases -> Liquidity Provider Intent System - Enable liquidity providers to send and receive USDC across multiple chains. -> Multichain Treasury Management - Help businesses manage USDC balances across multiple chains -> Universal Merchant Payment Gateway – Implement a multi-chain checkout system for merchants to accept -> USDC payments across various blockchains which rebalance to desired chain via CCTP V2.

Develop an application that enables users to pay network fees in USDC instead of native tokens by leveraging Circle Paymaster. *Please note that Circle Paymaster currently supports Arbitrum, Avalanche, Base, Ethereum, Optimism, Polygon and Unichain Example Use Cases -> DeFi Protocols - Enable USDC as the default gas payment token for transaction activitiy in dApps like Lido, AAVE, etc. -> Simplified transactions - Make it easier for users to perform transactions in USDC or other tokens while network fees are paid from their USDC balance.

Leverage Circle Wallets and the Gas Station feature to create a fully gas sponsored user experience.

Circle Gateway allows users to deposit USDC across supported chains and access it instantly on any chain without bridging or rebalancing. Build with this new primitive to enable chain-abstracted USDC experiences. note that Gateway is only available on testnet on Avalanche, Ethereum and Base - Multichain Checkout Flow: Enable users to pay merchants in USDC from a single balance, regardless of the chain the merchant is on. - Unified Multichain Wallet: Build a smart wallet UI where users can view, send, and receive USDC across chains with no bridging steps.
