Key Concepts

• Wallet Secret: Single cryptographic secret that grants access to all accounts across EVM and Solana
• Trusted Execution Environment (TEE): Secure enclave where private keys are stored and transactions signed, never exposed to Coinbase
• Smart Account: ERC-4337 compliant account enabling advanced features like batching and gas sponsorship
• User Operation: Transaction-like object for smart accounts supporting multiple operations in one call
• Spend Permission: Delegated authorization allowing specific spending limits and time-based restrictions
• Slippage: Maximum acceptable price difference between quote and execution
• MEV (Maximal Extractable Value): Protection against front-running and sandwich attacks in swaps

Rate Limits

• Standard API rate limits with higher tiers for enterprise customers
• WebSocket connections for real-time market data
• Batch operations for efficient bulk processing

Supported Networks

• EVM: Ethereum, Base, Arbitrum, Optimism, Polygon, and 50+ others
• Solana: Mainnet and Devnet
• Testnets: Base Sepolia, Ethereum Sepolia, Solana Devnet

Security Considerations

• Always use environment variables for API keys in production
• Rotate Wallet Secrets periodically
• Implement MFA for user accounts
• Use spend permissions to limit transaction scope
• Verify webhook signatures for payment notifications
• Test on testnets before mainnet deployment
