Frequently asked questions

Is it safe to add Factory 127 Mainnet 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 Factory 127 Mainnet Chain ID?▾
The Chain ID of Factory 127 Mainnet is 127. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need FETH tokens to use Factory 127 Mainnet?▾
Yes. Every transaction on Factory 127 Mainnet requires FETH to pay gas fees. You can purchase FETH on exchanges and bridge it to Factory 127 Mainnet, or use a faucet if this is a testnet.
What is the Factory 127 Mainnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Factory 127 Mainnet blockchain — sending transactions, reading balances, and checking state. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Factory 127 Mainnet already exists when I click Add — what do I do?▾
That's completely normal. If Factory 127 Mainnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Factory 127 Mainnet 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.
