Frequently asked questions

Is it safe to add TAC Saint Petersburg 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 TAC Saint Petersburg Chain ID?▾
The Chain ID of TAC Saint Petersburg is 2391. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need TAC tokens to use TAC Saint Petersburg?▾
Yes. Every transaction on TAC Saint Petersburg requires TAC to pay gas fees. You can purchase TAC on exchanges and bridge it to TAC Saint Petersburg, or use a faucet if this is a testnet.
What is the TAC Saint Petersburg RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the TAC Saint Petersburg blockchain — sending transactions, reading balances, and checking state. One popular TAC Saint Petersburg RPC is https://spb.rpc.tac.build. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says TAC Saint Petersburg already exists when I click Add — what do I do?▾
That's completely normal. If TAC Saint Petersburg is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added TAC Saint Petersburg 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.
