Connect to Tavchain

Open Add Tavchain Testnet in the same browser as your wallet and approve the network request. If your wallet does not support the button, enter the settings below manually.

Network details

Setting	Tavchain Testnet
Network name	Tavchain Testnet
RPC endpoint	`https://api.testnet.tavchain.safeney.com/`
Chain ID	`771002`
Currency symbol	`TAV`
Native currency	Tavcoin, 18 decimals
Block explorer	explorer.tavchain.safeney.com

Add the network

Open your wallet's network settings

Choose Add a custom network. Wallet labels vary by version; see MetaMask’s network guide.

Enter the network details

Copy the RPC endpoint, chain ID, currency symbol and explorer URL from the table above.

Select Tavchain Testnet

Save the settings and select the network before requesting Test TAV or sending a transaction.

Adding a network does not transfer funds or import a key into Tavchain’s server. No VPN, node installation or separate Tavchain registration is required for the wallet flow.

Check the network in your application

Select Tavchain Testnet for the connected site in the same browser as your wallet. Check that the application shows chain ID 771002 before signing. For Remix-specific steps, see Deploy a contract.

Using a previous Tavchain testnet?

The current EVM chain ID is 771002. Balances, account nonces and contracts from the previous 771001 networks are not carried forward. Select the current network and request fresh Test TAV.

For application developers

Add the network from an application

With a provider explicitly selected by your user, the common network-add request is:

await provider.request({
  method: "wallet_addEthereumChain",
  params: [{
  "chainId": "0xbc3ba",
  "chainName": "Tavchain Testnet",
  "nativeCurrency": {
    "name": "Tavcoin",
    "symbol": "TAV",
    "decimals": 18
  },
  "rpcUrls": [
    "https://api.testnet.tavchain.safeney.com/"
  ],
  "blockExplorerUrls": [
    "https://explorer.tavchain.safeney.com/"
  ]
}],
});

Ask separately to switch if needed using wallet_switchEthereumChain with chainId: "0xbc3ba". Wallets may decline either request. Check eth_chainId after selection; adding a network alone does not establish the active chain. Trigger wallet requests from an intentional user action, not page load. Treat this as a standard provider integration example and check behavior with the wallet versions your application supports.

Check the chain ID with JSON-RPC

curl --fail-with-body --max-time 10 \
  https://api.testnet.tavchain.safeney.com/ \
  -H 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'

The expected result is "0xbc3ba". An unavailable endpoint may return HTTP 503; do not switch to an unrelated chain or paste a private key into a website to work around it.
