Architectural Highlights

Official Circle Native USDC: Programmatically transfers official native USDC (Contract: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Mainnet, 0x036CbD53842c5426634e7929541eC2318f3dCF7e on Sepolia) via ERC-20 token standards with zero bridging risk.
EIP-4844 Blob Space Optimization: Leverages Ethereum data blobs to drastically suppress L1 rollup posting costs, keeping transaction fees under half a cent.
Web3 Native Wallet Compatibility: Works seamlessly with MetaMask, Rabby, Coinbase Wallet, and Coinbase Smart Wallets via standard EVM JSON-RPC and automated personal_sign nonce challenge proofs.
