⛓ Supported Chains

AgentTech supports multiple source chains, with all payments ultimately settling on Base.

Supported Chains

Chain	Identifier	Go Constant	TS Constant	Status
Solana	`"solana-mainnet-beta"`	`pay.ChainSolanaMainnet`	`Chain.SolanaMainnet`	Available
Base	`"base"`	`pay.ChainBase`	`Chain.Base`	Available
Polygon	`"polygon"`	`pay.ChainPolygon`	`Chain.Polygon`	Under maintenance
Arbitrum	`"arbitrum"`	`pay.ChainArbitrum`	`Chain.Arbitrum`	Under maintenance
Ethereum	`"ethereum"`	`pay.ChainEthereum`	`Chain.Ethereum`	Under maintenance
Monad	`"monad"`	`pay.ChainMonad`	`Chain.Monad`	Under maintenance
HyperEVM	`"hyperevm"`	`pay.ChainHyperEVM`	`Chain.HyperEvm`	Under maintenance

Settlement Chain

All payments settle on Base regardless of the source chain. The payerChain field in CreateIntentRequest specifies where the payer initiates the payment, but the final USDC transfer always occurs on Base.

Chain Identifiers

Use the chain constants from each SDK instead of hardcoded strings.

Usage

When creating an intent, specify the source chain using SDK constants:

import { Chain } from '@cross402/usdc';

const intent = await client.createIntent({
  email: "merchant@example.com",
  amount: "100.50",
  payerChain: Chain.Base,
});

resp, err := client.CreateIntent(ctx, &pay.CreateIntentRequest{
    Email:      "merchant@example.com",
    Amount:     "100.50",
    PayerChain: pay.ChainBase,
})
