Warning

Always start with a small test transaction. Bridge transfers are irreversible, so before moving large amounts, send a small amount first and confirm it arrives as expected.

The dedicated Bridge smart contract, controlled by the Gonka consensus, is active on Ethereum at the address:

0x972a7a92d92796a98801a8818bcf91f1648f2f68

Using the dashboard

The dashboard is the easiest way to bridge. It handles the key derivation for you (see Addresses and keys), so you don't need to import private keys or compute addresses by hand. Open it at:

https://node1.gonka.ai:8443/dashboard/

What the dashboard does for you

  • Derives the correct addresses. Connect the Ethereum wallet you bridge with, and the dashboard shows the matching gonka1… address the bridge will deliver tokens to — so you always know where your wrapped tokens will land.
  • Warns about seed-phrase accounts. If you are using a wallet whose Ethereum and Gonka keys come from the same mnemonic, the dashboard detects this and warns you, because seed-derived accounts use different keys on each chain and would send funds to an address you don't control. Read Addresses and keys for the full explanation.
  • Shows your bridged balances in a Bridge Assets section, so you can confirm a deposit arrived.
  • Reports chain status, so you can see if the chain is degraded before initiating a transfer.
  • Prompts for bridge epoch updates when the Ethereum bridge is behind the Gonka chain. If you see A Bridge needs epoch update, click Update bridge to submit the missing epoch key. This is a normal Ethereum transaction, so the connected wallet pays gas. See Bridge epoch update.

Supported flows

The dashboard supports the full set of transfers without using the CLI:

  • Ethereum → Gonka: deposit any ERC-20 (USDT, USDC, WETH, …) and receive the wrapped token on Gonka.
  • Gonka → Ethereum: withdraw a wrapped token back to an Ethereum address.
  • GNK ↔ WGNK: bridge native GNK to Ethereum as WGNK and back.

Typical deposit (Ethereum → Gonka)

  1. Open the dashboard and connect your Ethereum wallet.
  2. Confirm the derived gonka1… recipient address shown by the dashboard is one you control.
  3. Choose the token and amount and approve the transfer to the bridge contract.
  4. Wait ~15–20 minutes for Ethereum finalization (see Timing & finalization), then check the Bridge Assets section for your wrapped balance.

Typical withdrawal (Gonka → Ethereum)

  1. Connect, select the wrapped token and amount, and enter the destination Ethereum address.
  2. Approve the withdrawal. The dashboard collects the BLS signature for the current epoch and submits the release transaction to the bridge contract on Ethereum.

Tip

Prefer the dashboard if you are not comfortable with the CLI or with handling raw private keys. The step-by-step CLI flows are documented in Deposit USDT, Withdraw USDT, Deposit GNK, and Withdraw GNK if you prefer to do it manually.
