TAC Network RPC Infrastructure

TAC offers full EVM compatibility through its Layer 1 blockchain. Use the TAC public RPC endpoints for development and production environments.

TAC Public RPC Endpoints

Network	Endpoint
Mainnet	https://rpc-public.tac.build
SPB Testnet	https://rpc-public-spb.tac.build

Integration Steps

Choose Your Integration Method

The TAC Network supports multiple access methods:

EVM JSON-RPC: For standard Ethereum-compatible development
Tendermint: Direct access to the consensus layer
Cosmos REST/gRPC: For Cosmos SDK-based interactions

Configure Your Application

For EVM application integration using TAC public RPC endpoints:

// Example configuration with ethers.js
import { ethers } from 'ethers';

// Connect via TAC's public testnet RPC endpoint
const provider = new ethers.providers.JsonRpcProvider('https://rpc-public-spb.tac.build');

// Test connection
async function checkConnection() {
  const blockNumber = await provider.getBlockNumber();
  console.log(`Connected to TAC network at block: ${blockNumber}`);
}

Or for deployment on TAC L1 using Foundry

forge create --rpc-url https://rpc-public-spb.tac.build --private-key YOUR_PRIVATE_KEY_HERE YOUR_CONTRACT --legacy --broadcast

Testing Your Integration

Before production deployment:

Get testnet tokens from the TAC Faucet
Test transactions through TAC public RPC endpoints
Monitor performance via the Explorer

For enterprise-level support or custom RPC requirements, contact the TAC team directly.
