One-click Bridge is a solution built & maintained by Karat. One-click Bridge has indexers and liquidity pools operated by Karat. When a user deposits a native token on the source chain, One-click Bridge automatically detects the deposit event and waits for sufficient block confirmations before making the transaction on the user's behalf on zkSync chain. This eliminates the need for users to perform the transaction manually, thereby reducing the chances of errors and delays.

For example, if you want to purchase Karat's Validator NFT pass on zkSync, you would typically need to bridge your ETH from Ethereum to zkSync first. This process can take up to 5 minutes and would cost around $20-30 in gas fees. With One-click Bridge, all you need to do is deposit funds on your preferred chain, such as Ethereum, Polygon, or BSC, and Karat's bridge will automatically mint the NFT for you once it detects the deposit event. This will cost you less than $3 for a transaction, which is a massive 90% savings!

One-click Bridge does not charge any protocol fees, so you can rest assured that you are only paying for the gas or mint fees on the zkSync chain. With One-click Bridge, you can enjoy a seamless and cost-effective cross-chain transfer experience.
