Monad Testnet
A second EVM source network integrated alongside Fuji, with accounts, USDC payments and a vault for Stellar Testnet.
Network parameters
eip155:10143 · CCTP domain 15 · gas MON · destination stellar:testnet. The USDC EIP-712 domain is USDC / 2; do not reuse Avalanche’s USD Coin / 2.
Recorded tests
The 13 October log records Router, RouterV2, AccountFactory and Vault deployments, 0.01 USDC payments in dev_signer, dev_gasless and account modes, and a 0.5 USDC disbursement. A later dev_gasless payment was checked against the rebuilt container, along with events and MON resources in the monitor.
Integrate through SDK or API
Use the monad alias with environment:testnet in the SDK, or sourceNetwork:eip155:10143 in the API. Query /v1/routes to check enabled modes and /health to confirm the environment. MCP 0.2.0 does not select Monad; x402 on Monad requires its own end-to-end test.
Availability depends on your instance. Check /health and /v1/routes before integrating.
