Getting your funds onto Ink Chain is the first step toward accessing the trading and DeFi opportunities available on Kraken's Layer 2. Whether you are coming from Ethereum mainnet, another L2, or a centralized exchange, this guide covers every path to get your assets onto Ink.

What You Need Before Bridging

Before you start, make sure you have the following:

A Web3 wallet such as MetaMask, Rabby, or Coinbase Wallet
ETH for gas fees on your source chain (the chain you are bridging from)
The tokens you want to bridge (ETH, USDT, USDC, or other supported assets)

If you have never added Ink Chain to your wallet, here are the network details:

Network Name: Ink
RPC URL: https://rpc-gel.inkonchain.com
Chain ID: 57073
Currency Symbol: ETH
Block Explorer: https://explorer.inkonchain.com

Most modern wallets will auto-detect Ink when you interact with an Ink dApp, but you can add it manually using these details.

Method 1: The Official Ink Bridge

The simplest and most trusted option is the official Ink bridge at bridge.inkonchain.com.

Step-by-Step Instructions

Step 1: Navigate to the official bridge interface and connect your wallet.

Step 2: Select your source chain. The bridge supports Ethereum mainnet, and additional chains may be available depending on current integrations.

Step 3: Choose the token you want to bridge. ETH is the most common choice since it serves as the gas token on Ink. USDT0 is the stablecoin standard used across Ink DeFi protocols.

Step 4: Enter the amount you want to bridge. The interface will display estimated gas fees and arrival time.

Step 5: Approve the transaction in your wallet. For ERC-20 tokens like USDT, you may need to approve the bridge contract before the actual bridge transaction.

Step 6: Confirm the bridge transaction. You will see a transaction hash that you can track on Etherscan (source chain) and the Ink block explorer (destination).

Step 7: Wait for confirmation. Bridging from Ethereum L1 to Ink typically takes 1-5 minutes for the deposit to be recognized. Your funds will appear in your Ink wallet once the transaction is finalized.

Important Notes on the Official Bridge

Bridging from L1 to L2 is fast (minutes). Withdrawing from L2 back to L1 through the canonical bridge involves a 7-day challenge period (standard for optimistic rollups)
Always verify you are on the official bridge URL to avoid phishing
Gas fees on Ethereum L1 are required for the initial bridge transaction

Method 2: Third-Party Bridges

Several third-party bridges support Ink Chain and can offer faster routes, especially from other L2s.

Relay Bridge

Relay is a cross-chain bridge that supports transfers between multiple L2s and Ink. It often provides the fastest bridging experience with minimal fees.

Supports bridging from Base, Optimism, Arbitrum, and other chains directly to Ink
Typical transfer time: under 30 seconds for L2-to-L2 bridges
Competitive fees, often cheaper than going through L1

Superbridge

As an OP Stack chain, Ink is compatible with Superbridge, which provides a clean interface for moving assets between Superchain networks.

Optimized for OP Stack to OP Stack transfers
Leverages native message passing for security
Supports ETH and major stablecoins

Owlto Finance

Owlto is another popular cross-chain bridge that has integrated Ink Chain. It supports a wide range of source chains and tokens.

Method 3: From a Centralized Exchange

If your funds are currently on a centralized exchange, you have a couple of options.

Direct Withdrawal to Ink (Where Available)

Some exchanges are beginning to support direct withdrawals to Ink Chain. Kraken, as the creator of Ink, is the most likely to offer this integration. Check your exchange's withdrawal options and look for "Ink" or "Ink Chain" as a network option.

Two-Step Process

If your exchange does not support direct Ink withdrawals:

Withdraw to Ethereum mainnet (or a supported L2)
Bridge from that chain to Ink using one of the methods above

This adds an extra step but is reliable and widely supported.

Choosing the Right Token to Bridge

The Ink DeFi ecosystem primarily uses two tokens:

ETH is the native gas token. You need a small amount of ETH on Ink to pay for transaction fees. Since gas fees on Ink are typically under $0.01, even 0.01 ETH will last for hundreds of transactions.

USDT0 is the standard stablecoin on Ink. If you plan to trade on Nado Protocol (perpetual futures) or use Otomate's copy trading and automation features, USDT0 is the collateral token you will need. It uses a 6-decimal format and is the quote currency for all Nado markets.

If you are bridging USDT from Ethereum, it will convert to USDT0 on Ink. The value is identical, and the conversion is handled automatically by the bridge.

Cost Optimization Tips

Bridge during low gas periods. Ethereum L1 gas fees fluctuate throughout the day. If you are bridging from mainnet, check gas trackers and bridge during off-peak hours (typically weekends or early morning UTC).

Use L2-to-L2 bridges when possible. If your funds are already on Base, Optimism, or Arbitrum, bridging directly to Ink via Relay or another L2 bridge is significantly cheaper than going through L1.

Batch your bridging. Rather than making multiple small bridge transactions, consolidate into one larger transfer to minimize gas overhead.

Keep some ETH for gas. Always bridge slightly more ETH than you think you need. Running out of gas on a new chain is a common frustration.

Security Considerations

Bridging involves interacting with smart contracts that hold significant value, so security awareness is essential.

Verify URLs carefully. Always navigate to bridge interfaces through official links. Bookmark the official Ink bridge and third-party bridges you trust. Phishing sites that mimic bridge interfaces are a common attack vector.

Start with a small test transaction. If you are bridging to Ink for the first time, send a small amount first to confirm everything works before bridging your full balance.

Understand withdrawal timelines. The canonical bridge from Ink back to Ethereum L1 has a 7-day challenge period. Third-party bridges can facilitate faster withdrawals but may charge higher fees. Plan accordingly if you need quick liquidity.

Check contract approvals. When bridging ERC-20 tokens, you may be asked to approve unlimited spending. Consider approving only the amount you need, especially with less established bridges.

After You Bridge: What to Do on Ink

Once your funds arrive on Ink Chain, you are ready to explore the ecosystem:

Trade perpetual futures on Nado Protocol with up to 20x leverage on BTC, ETH, SOL, and more
Swap spot tokens via 0x-powered aggregation through Otomate or other Ink DEXs like InkySwap and Velodrome
Automate your trading with Otomate's AI Copilot, strategy builder, or copy trading features
Provide liquidity on Velodrome or other Ink AMMs for yield farming
Explore new protocols launching on Ink as the ecosystem grows

Troubleshooting Common Issues

Funds not appearing after bridge: Check the transaction on both the source chain explorer and the Ink explorer. Some bridges have a delay before funds are credited. Wait at least 10 minutes before troubleshooting further.

Wrong network in wallet: Make sure your wallet is connected to Ink Chain (Chain ID 57073). Your tokens exist on the destination chain, so you need to be viewing the correct network.

Token not showing in wallet: You may need to manually add the token contract address to your wallet. Check the Ink block explorer for the correct token address.

Wrapping Up

Bridging to Ink Chain is straightforward, and the ecosystem of bridge options continues to grow. Whether you use the official bridge from L1 or a third-party bridge from another L2, the process takes minutes and costs very little.

Once your funds are on Ink, you have access to one of the most trading-focused L2 ecosystems in crypto. The combination of Nado Protocol's perpetual DEX and Otomate's automation tools means your bridged capital can be put to work immediately.
