Choosing a Chain
L2 chains (Base, Arbitrum) offer the fastest settlement and lowest gas. Consider these factors when choosing:
| Factor | Guidance |
|---|
| API monetization / micropayments | Base or Arbitrum (low gas, fast) |
| Large value transactions | Ethereum (deepest liquidity) |
| FDUSD settlement | BSC or Ethereum |
| Maximum agent compatibility | Accept multiple chains |
Accept payments on multiple chains to maximize compatibility with different
agent wallets. Settlement is simplest when both the agent and merchant operate
on the same chain.
