AgentWallex currently supports the following blockchain networks for agent wallets and transactions:

Chain	Chain ID	Type	Supported Tokens
Ethereum	`eip155:1`	EVM Mainnet	ETH, USDC, USDT, DAI
Base	`eip155:8453`	EVM L2	ETH, USDC
Polygon	`eip155:137`	EVM L2	MATIC, USDC, USDT

Use testnets for development and testing — no real funds at risk:

When initializing the SDK with environment: "sandbox", all operations automatically use testnet chain IDs.

The x402 micropayment protocol currently supports a subset of chains for payment negotiation and settlement:

Query the supported chains programmatically:

curl -X GET https://api.agentwallex.com/api/v1/x402/facilitator/supported

The following chains are on the roadmap:

Want a chain that is not listed here? Contact the AgentWallex team at support@agentwallex.com or request it through the dashboard.

AgentWallex uses CAIP-2 chain identifiers:

When creating agents or transactions, always use the full CAIP-2 chain ID:

const agent = await aw.agents.create({
  name: "my-agent",
  chain: "eip155:8453", // Base mainnet
});
