Why Build on Tempo?

Tempo is a payments-first EVM blockchain designed for stablecoin settlement and financial application UX. Instead of forcing users to manage a native gas token, Tempo denominates fees in supported USD stablecoins while keeping standard Ethereum JSON-RPC compatibility.

Stablecoin-Native Fees

• No native gas token - users pay fees in supported USD stablecoins
• Predictable pricing - easier wallet and checkout UX for payment flows
• Cleaner treasury logic - applications can reason about settlement costs in dollar terms

Built for Payment Workloads

• Deterministic settlement - optimized for fast, reliable payment confirmation
• Merchant-friendly design - suitable for payouts, invoices, and treasury automation
• Wallet-aware fee flows - fee token preferences can be managed at the account level

Standard EVM Tooling

• EVM compatible - keep your Solidity contracts and familiar SDKs
• Trace and debug ready - Dwellir exposes trace_*, debug_*, and txpool_*
• HTTPS and WebSocket - use the same endpoint shape as other EVM integrations

Quick Start with Tempo

Connect to Tempo mainnet with Dwellir:

Tempo RPC Endpoints

curlJavaScriptPythonGo

curl -sS -X POST https://api-tempo-mainnet.n.dwellir.com/<API_Keys_Are_Not_Made_for_Bots> \  -H 'Content-Type: application/json' \  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

import { JsonRpcProvider } from 'ethers';const provider = new JsonRpcProvider(  'https://api-tempo-mainnet.n.dwellir.com/<API_Keys_Are_Not_Made_for_Bots>');const latest = await provider.getBlockNumber();console.log('block', latest);

import requestsurl = 'https://api-tempo-mainnet.n.dwellir.com/<API_Keys_Are_Not_Made_for_Bots>'payload = {  'jsonrpc': '2.0', 'id': 1,  'method': 'eth_blockNumber', 'params': []}resp = requests.post(url, json=payload)print(resp.json())

package mainimport (  "bytes"  "fmt"  "io"  "net/http")func main() {  url := "https://api-tempo-mainnet.n.dwellir.com/<API_Keys_Are_Not_Made_for_Bots>"  payload := []byte(`{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}`)  resp, err := http.Post(url, "application/json",    bytes.NewBuffer(payload))  if err != nil { panic(err) }  defer resp.Body.Close()  body, _ := io.ReadAll(resp.Body)  fmt.Println(string(body))}

Installation & Setup

import { JsonRpcProvider } from 'ethers';

const provider = new JsonRpcProvider(
  'https://api-tempo-mainnet.n.dwellir.com/YOUR_API_KEY'
);

const chainId = await provider.send('eth_chainId', []);
console.log('Tempo chain ID:', parseInt(chainId, 16));

const block = await provider.getBlock('latest');
console.log('Latest block:', block.number);

Tempo Fee Model Notes

Tempo does not behave like a typical ETH-gas chain:

• No native token balance requirement for paying fees
• Fee quotes are stablecoin-denominated, so wallet and app UX should not assume ETH-style gas handling
• Fee token preferences matter because users can pay with supported stablecoins instead of a single mandatory gas asset

If your wallet or payment flow assumes eth_getBalance reflects spendable fee balance, adjust that logic for Tempo before launch.

API Reference

Tempo supports standard Ethereum JSON-RPC methods, and Dwellir's endpoint also exposes trace, debug, and txpool namespaces for production operations and debugging.

Common Integration Patterns

Stablecoin Payment Monitoring

async function waitForSettlement(txHash) {
  const receipt = await provider.waitForTransaction(txHash, 1);
  console.log('Settled in block:', receipt.blockNumber);
  return receipt;
}

Fee Estimation in Stablecoin Terms

const feeData = await provider.getFeeData();
const gasEstimate = await provider.estimateGas(tx);

const approxUsdCost =
  Number(feeData.gasPrice) / 1e9 * Number(gasEstimate) / 1e9;

console.log('Estimated fee (USD):', approxUsdCost);

Trace Support for Payment Debugging

const trace = await provider.send('debug_traceTransaction', [
  '0x50b1857dce8dbe401e09610534de81655bc508c6765eb30ecefe24148c515c28'
]);

console.log('Trace result:', trace);
