Tempo is an EVM-compatible blockchain built for payments, settlement, and stablecoin workflows. Instead of relying on a native gas token, Tempo lets users pay transaction fees in supported USD stablecoins, which makes costs easier to reason about for wallets, merchant flows, and financial applications.

Which Tempo RPC endpoint should I use?

Pick by what you are building. Mainnet runs on archive nodes, so calls at any past block work.

FAQs

Tempo mainnet is chain ID 4217 (0x1079). There is no native token. Fees are quoted in attodollars per gas and paid in any USD TIP-20 stablecoin with Fee AMM liquidity, with pathUSD at 0x20c0000000000000000000000000000000000000 as the fallback. eth_getBalance returns a constant placeholder on every account, so read stablecoin balances with balanceOf instead.

Call transfer(to, amount) on the TIP-20 token with a 6-decimal amount. USDT0 is at 0x20c00000000000000000000014f22ca97301eb73, bridged USDC.e at 0x20c000000000000000000000b9537d11c60e8b50, and pathUSD at 0x20c0000000000000000000000000000000000000. A standard EIP-1559 transaction works and the fee is taken from the token you are transferring; a transfer costs about 50,000 gas, or roughly $0.00003 at the base fee floor. The Stablechain RPC guide has the viem example and the fee-token rules.

Tempo is the only one of the four with no native gas token. Arc pays gas in USDC, Stable in USDT0, and Plasma in XPL. All four finalize in about a second or less and run standard Ethereum JSON-RPC, and Dwellir serves mainnet endpoints for each. The Stablechain RPC guide compares chain IDs, endpoints, gas models and finality in one table.

Tempo is designed around payments and stablecoin settlement. It removes the native gas token requirement and lets users pay transaction fees in supported USD stablecoins, which is a better fit for merchant apps, treasury flows, and financial UX.

Dwellir exposes Tempo mainnet over HTTPS and WebSocket at https://api-tempo-mainnet.n.dwellir.com/<your-api-key> and wss://api-tempo-mainnet.n.dwellir.com/<your-api-key>. The endpoint uses Chain ID 4217 and supports standard Ethereum JSON-RPC methods plus trace/debug namespaces.

Tempo does not use a native gas token. Fees are denominated in USD and paid in supported stablecoins, so wallets and apps need to treat fee balances differently from ETH-style networks.

Yes. The Tempo mainnet endpoint on Dwellir exposes eth, net, web3, trace, debug, txpool, and rpc namespaces, so you can inspect transactions, blocks, and execution traces with standard EVM tooling.
