Frequently asked questions

Is it safe to add Fuse Flash 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 Fuse Flash Testnet Chain ID?▾
The Chain ID of Fuse Flash Testnet is 10920. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need FUSE tokens to use Fuse Flash Testnet?▾
Yes. Every transaction on Fuse Flash Testnet requires FUSE to pay gas fees. You can purchase FUSE on exchanges and bridge it to Fuse Flash Testnet, or use a faucet if this is a testnet.
What is the Fuse Flash Testnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Fuse Flash Testnet 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 Fuse Flash Testnet already exists when I click Add — what do I do?▾
That's completely normal. If Fuse Flash Testnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Fuse Flash 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.
