How to use this section

  1. Pick your network.
  2. Paste your API key, or leave it empty to copy the placeholder form.
  3. Copy the snippet for your tool — MetaMask, viem, ethers, Hardhat, Foundry or wagmi.

FAQ

Which networks are here?
Every network Triport serves. Solana, Stellar and TON are not EVM chains: their pages give the genesis hash, network passphrase or global ID and the RPC URLs, but no EVM wallet config, which would be meaningless. Robinhood Chain has its own page.
Is my API key sent anywhere?
No. Snippets are generated in your browser, and the key is never submitted, stored or written into the page URL — which is why these pages have no shareable link.
Which testnet should I use for Ethereum?
Sepolia (chain ID 11155111) for applications — ethereum.org calls it the recommended default testnet for application development — and Hoodi (560048) for testing validating and staking. Holešky is shut down. Triport serves mainnet only; each network page lists its testnets with sources.
Why does Tron have no MetaMask snippet?
Tron exposes an EVM JSON-RPC surface that viem, ethers, Hardhat and Foundry can read, but MetaMask does not manage TRX accounts through wallet_addEthereumChain, so publishing that snippet would be misleading.
