Frequently asked questions

Is it safe to add Dos Fuji Subnet 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 Dos Fuji Subnet Chain ID?▾
The Chain ID of Dos Fuji Subnet is 1311. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need DOS tokens to use Dos Fuji Subnet?▾
Yes. Every transaction on Dos Fuji Subnet requires DOS to pay gas fees. You can purchase DOS on exchanges and bridge it to Dos Fuji Subnet, or use a faucet if this is a testnet.
What is the Dos Fuji Subnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Dos Fuji Subnet blockchain — sending transactions, reading balances, and checking state. One popular Dos Fuji Subnet RPC is https://test.doschain.com/jsonrpc. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Dos Fuji Subnet already exists when I click Add — what do I do?▾
That's completely normal. If Dos Fuji Subnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Dos Fuji Subnet 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.
