Overview

Public Rome chains — chain IDs, RPC endpoints, explorers, and gas tokens.

Rome runs multiple public chains. Two are the ones to build against today: Martius (testnet) and Hadrian (devnet). Both are EVM chains that execute inside a Solana program and settle on Solana Devnet, so devnet SOL is not real money.

Network	Chain ID	RPC	Explorer	Gas token
Martius (testnet)	121214	https://martius.testnet.romeprotocol.xyz/	via-martius	USDC
Hadrian (devnet)	200010	https://hadrian.testnet.romeprotocol.xyz/	via-hadrian	USDC
Local	1001	http://localhost:9090	—	—

Chain metadata — chain IDs, contract addresses, token mints, gas pools — is canonical in the Rome registry. Don't hardcode addresses; read them from there.

Add a network to your wallet

Each network page lists the manual MetaMask values. WebSocket subscriptions are served on the same host as the HTTPS RPC (swap https:// for wss://).

Fund a wallet

Rome's public chains settle on Solana Devnet. Get devnet SOL from the Solana faucet, then obtain a chain's gas token through the Rome App (wrap/bridge). For test tokens on every chain the bridge supports, see Faucets.

Local development

Develop against a public chain today — see the Quickstart. A self-contained local stack (chain ID 1001, Proxy on :9090) is on the roadmap.
