Frequently asked questions

Is it safe to add Rome Testnet Martius to MetaMask?▾

Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.

What is Rome Testnet Martius Chain ID?▾

The Chain ID of Rome Testnet Martius is 121214. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.

Do I need RSOL tokens to use Rome Testnet Martius?▾

Yes. Every transaction on Rome Testnet Martius requires RSOL to pay gas fees. You can purchase RSOL on exchanges and bridge it to Rome Testnet Martius, or use a faucet if this is a testnet.

What is the Rome Testnet Martius RPC endpoint?▾

An RPC endpoint is the server address your wallet uses to communicate with the Rome Testnet Martius blockchain — sending transactions, reading balances, and checking state. One popular Rome Testnet Martius RPC is https://martius-i.testnet.romeprotocol.xyz. This page shows live latency for each RPC so you can pick the fastest one.

My wallet says Rome Testnet Martius already exists when I click Add — what do I do?▾

That's completely normal. If Rome Testnet Martius is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.

I added Rome Testnet Martius but the network won't load — what's wrong?▾

The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
