Frequently asked questions

Is it safe to add Filecoin - Calibration testnet 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 Filecoin - Calibration testnet Chain ID?
The Chain ID of Filecoin - Calibration testnet is 314159. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need tFIL tokens to use Filecoin - Calibration testnet?
Yes. Every transaction on Filecoin - Calibration testnet requires tFIL to pay gas fees. You can purchase tFIL on exchanges and bridge it to Filecoin - Calibration testnet, or use a faucet if this is a testnet.
What is the Filecoin - Calibration testnet RPC endpoint?
An RPC endpoint is the server address your wallet uses to communicate with the Filecoin - Calibration testnet blockchain — sending transactions, reading balances, and checking state. One popular Filecoin - Calibration testnet RPC is https://api.calibration.node.glif.io/rpc/v1. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Filecoin - Calibration testnet already exists when I click Add — what do I do?
That's completely normal. If Filecoin - Calibration testnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Filecoin - Calibration testnet 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.
