What is Tempo Testnet?

Tempo Testnet is an EVM (Ethereum Virtual Machine) compatible blockchain network. Any EVM wallet — MetaMask, Rabby, OKX Wallet, Trust Wallet, Coinbase Wallet — can connect and transact on Tempo Testnet once you add the network configuration.

Why do you need to add Tempo Testnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Tempo Testnet, you need to add the network first. Entering an incorrect Chain ID or RPC can put your assets at risk. Use the "Add to wallet" button above — data sourced directly from chainid.network, the canonical Ethereum chain registry.

Frequently asked questions

Is it safe to add Tempo 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 Tempo Testnet Chain ID?▾
The Chain ID of Tempo Testnet is 42431. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need USD tokens to use Tempo Testnet?▾
Yes. Every transaction on Tempo Testnet requires USD to pay gas fees. You can purchase USD on exchanges and bridge it to Tempo Testnet, or use a faucet if this is a testnet.
What is the Tempo Testnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Tempo Testnet blockchain — sending transactions, reading balances, and checking state. One popular Tempo Testnet RPC is https://rpc.testnet.tempo.xyz. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Tempo Testnet already exists when I click Add — what do I do?▾
That's completely normal. If Tempo Testnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Tempo 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.
