Official documentation
TAC EVM Layer provides full compatibility with Hardhat, Ethereum’s most popular development framework. Deploy your existing Solidity contracts without modification, test, and verify contracts on the Block Explorer.

​
Installation & Setup

Setting up Hardhat for TAC development requires no special configuration - it works exactly like any other EVM chain. Refer to our example app create-tac-app to see the relevant hardhat deployment approach.

​
Deployment

Below you can find the deployment commands used within create-tac-app
Ensure you have sufficient TAC tokens for gas fees before deploying to mainnet.

Common Issues & Solutions

Problem: RPC connection failures or timeoutsSolutions:
  • Verify RPC URLs are correct
  • Increase timeout in network configuration
networks: {
    tacTestnet: {
        url: "https://spb.rpc.tac.build",
        timeout: 60000, // Increase timeout
    }
}
  • Try alternative RPC endpoints if available
