Supported Networks

The Consensus facilitator at https://facilitator.canister.software supports the networks below; GET /supported on the facilitator returns the live list. A resource server may accept payment on any subset of them, and the client picks the network that matches its registered signer.

EVM Networks

EVM payments use the USDC token and the exact scheme. Prices are expressed in USDC atomic units (6 decimal places — 1 USDC = 1,000,000 units) or as a dollar string (e.g. "$0.001") which the server converts internally.

Base Mainnet

Property	Value
Network identifier	`eip155:8453`
Token	USDC
Chain	Base (mainnet)
Status	Production

{ scheme: 'exact', price: '$0.001', network: 'eip155:8453', payTo: process.env.EVM_PAY_TO }

Base Sepolia

Property	Value
Network identifier	`eip155:84532`
Token	USDC
Chain	Base Sepolia (testnet)
Status	Testnet

{ scheme: 'exact', price: '$0.001', network: 'eip155:84532', payTo: process.env.EVM_PAY_TO }

Server registration (EVM)

import { ExactEvmScheme } from '@x402/evm/exact/server'

x402Server
  .register('eip155:8453',  new ExactEvmScheme())
  .register('eip155:84532', new ExactEvmScheme())

Client registration (EVM)

import { registerExactEvmScheme } from '@x402/evm/exact/client'
import { privateKeyToAccount } from 'viem/accounts'

const key = process.env.EVM_PRIVATE_KEY
const signer = privateKeyToAccount(key.startsWith('0x') ? key : `0x${key}`)
registerExactEvmScheme(client, { signer })

Solana Networks

Solana payments use USDC and the exact scheme. Prices are expressed in USDC atomic units (6 decimal places) or as a dollar string.

Solana Mainnet

Property	Value
Network identifier	`solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp`
Token	USDC
Chain	Solana (mainnet)
Status	Production

{ scheme: 'exact', price: '$0.001', network: 'solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp', payTo: process.env.SOLANA_PAY_TO }

Solana Devnet

Property	Value
Network identifier	`solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1`
Token	USDC
Chain	Solana (devnet)
Status	Testnet

{ scheme: 'exact', price: '$0.001', network: 'solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1', payTo: process.env.SOLANA_PAY_TO }

Server registration (Solana)

import { ExactSvmScheme } from '@x402/svm/exact/server'

x402Server
  .register('solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp',      new ExactSvmScheme())
  .register('solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1',       new ExactSvmScheme())

Client registration (Solana)

import { registerExactSvmScheme } from '@x402/svm/exact/client'
import { createKeyPairSignerFromBytes } from '@solana/signers'
import bs58 from 'bs58'

const keyBytes = bs58.decode(process.env.SOLANA_PRIVATE_KEY)
const signer = await createKeyPairSignerFromBytes(keyBytes)
registerExactSvmScheme(client, { signer })

ICP Networks

ICP payments use the exact scheme with ICP, ckUSDC, ckUSDT, or a test token; the network identifier names the token’s ledger canister. The examples below use TESTICP, the token the Consensus server accepts. Prices are expressed in e8s — the smallest unit of the token (1 ICP = 100,000,000 e8s).

ICP Testnet

Property	Value
Network identifier	`icp:1:xafvr-biaaa-aaaai-aql5q-cai`
Token	TESTICP
Ledger canister	`xafvr-biaaa-aaaai-aql5q-cai`
Pay-to format	ICP principal
Status	Testnet

e8s conversion reference

e8s	TESTICP
`100`	0.000001
`10,000`	0.0001
`100,000`	0.001
`1,000,000`	0.01
`100,000,000`	1.0

{ scheme: 'exact', price: '100000', network: 'icp:1:xafvr-biaaa-aaaai-aql5q-cai', payTo: process.env.ICP_PAY_TO }

Server registration (ICP)

import { ExactIcpScheme } from '@canister-software/x402-icp/server'

x402Server.register('icp:1:xafvr-biaaa-aaaai-aql5q-cai', new ExactIcpScheme())

Client registration (ICP)

import { registerExactIcpScheme, pemToSigner } from '@canister-software/x402-icp/client'

const signer = await pemToSigner(process.env.PEM_PATH)
registerExactIcpScheme(client, { signer })
