Active Chains
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 |
| BNB Smart Chain | eip155:56 | EVM Mainnet | BNB, USDC, USDT, BUSD |
| Tron | tron:mainnet | Non-EVM | TRX, USDT |
| Bitcoin | bip122:mainnet | UTXO | BTC |
Testnets
Use testnets for development and testing — no real funds at risk:
| Chain | Chain ID | Faucet |
|---|
| Base Sepolia | eip155:84532 | Coinbase Faucet |
| Ethereum Sepolia | eip155:11155111 | Sepolia Faucet |
| Polygon Amoy | eip155:80002 | Polygon Faucet |
When initializing the SDK with environment: "sandbox", all operations automatically use testnet chain IDs.
x402 Supported Chains
The x402 micropayment protocol currently supports a subset of chains for payment negotiation and settlement:
| Chain | Chain ID | Settlement Token |
|---|
| Base Sepolia (testnet) | eip155:84532 | USDC |
| Base | eip155:8453 | USDC |
| Ethereum | eip155:1 | USDC |
| Polygon | eip155:137 | USDC |
Query the supported chains programmatically:
curl -X GET https://api.agentwallex.com/api/v1/x402/facilitator/supported
Coming Soon
The following chains are on the roadmap:
| Chain | Chain ID | Expected | Notes |
|---|
| Solana | solana:mainnet | Q2 2026 | SPL token support |
| Avalanche C-Chain | eip155:43114 | Q2 2026 | EVM compatible |
| Arbitrum One | eip155:42161 | Q3 2026 | EVM L2 |

AgentWallex uses CAIP-2 chain identifiers:
- EVM chains:
eip155:<chain_id> (e.g., eip155:1 for Ethereum mainnet)
- Bitcoin:
bip122:mainnet
- Tron:
tron:mainnet
- Solana (coming soon):
solana:mainnet
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
});
