Our verdict on Ink Bridge

6.8/10

Ink Bridge suits users who want to move ETH from Ethereum to Ink, the Kraken-released Superchain L2, and prefer the official route over third-party options. Its main strengths are the Kraken association, a simple interface and about $56 million in TVL. The main caveat is missing detail: no audits are listed on DefiLlama and fees and withdrawal times are not published publicly. Check the official docs and bridge a small amount first.

What is Ink Bridge?

Ink Bridge is the canonical bridge between Ethereum and Ink, a Layer 2 blockchain built on Optimism's Superchain and released by Kraken. DefiLlama describes it as the bridge for the Ink chain by Kraken and tracks about $56 million in TVL, up 3.2% over seven days.

The Ink homepage presents the bridge as the first step in a short flow: bridge, trade, then earn. Featured apps include Nado, a central limit order book DEX, Tydro, a liquidity protocol powered by Aave, Velodrome and Uniswap. Kraken and Kraken Wallet are also listed.

The homepage footer credits Payward, Inc. The project does not name an audit report, a withdrawal period or a fee schedule for the bridge, so this review is limited to what the public pages and DefiLlama show.

How Ink Bridge works

A canonical bridge is the official route a Layer 2 uses to move assets from its parent chain. You lock or deposit assets on Ethereum, and the equivalent balance becomes available on the L2. Going back, you withdraw from the L2 to Ethereum.

Ink is built on Optimism's Superchain, so its bridge follows the OP Stack model for rollups. The project does not detail the exact proof system or withdrawal timing, so those should be checked in the official documentation.

On the website, the bridge widget asks for a source asset (ETH on Ethereum), an amount and a destination address, then needs a wallet connection to proceed.

6 features

Key features

Canonical Ethereum bridge

DefiLlama classes it as a canonical bridge for the Ink chain, meaning it is the chain's primary route from Ethereum.

ETH bridging interface

The bridge widget on the homepage starts with ETH on Ethereum and takes a destination address after a wallet connection.

Superchain-based L2

Ink is built on Optimism's Superchain, which puts it in the same family of rollups as other Superchain chains.

Connected app ecosystem

The homepage links the bridge to trade and earn pages, with featured apps such as Nado, Tydro, Velodrome and Uniswap.

Third-party bridge options

Several listed apps, such as Across Protocol, Eco Portal and Bungee, offer other ways to move assets to Ink.

Developer tooling

The homepage shows developer configuration for an Ink RPC endpoint, pointing to builders using Foundry.

Pros and cons

What we like

Official canonical bridge for Ink, so it is the primary route from Ethereum.
Backed by Kraken's parent company, a well-known exchange operator.
Roughly $56 million TVL gives it meaningful usage.
Built on Optimism's Superchain, a widely used L2 framework.
Simple interface that starts with ETH on Ethereum and a destination address.
A broad app ecosystem is linked directly from the homepage.

Watch out for

No audits are listed on DefiLlama for the bridge, and the project does not name any audit firms or reports.
Bridge security rules, such as withdrawal delay and proof system, are not described publicly.
Fees and withdrawal times are not published in the material reviewed.
Tied to a single L2, Ink, so it is useful mainly to people who want to use that chain.
Runs under Kraken's parent company (Payward, Inc.), which adds a centralization and counterparty consideration compared with a community-run bridge.
The ecosystem listing includes many third-party apps that Ink does not necessarily vet, so the bridge page alone does not tell you the risk of those apps.

Ink Bridge fees

Ink Bridge fees are not published publicly reviewed. A bridge from Ethereum would normally involve Ethereum gas fees, and the bridge interface should show the cost before you confirm.

Some third-party bridges listed in the ecosystem advertise their own fees, such as the Eco Portal's single low fee, but those are separate products and no figures are stated here.

Is Ink Bridge safe?

DefiLlama lists no audits for this entry. The project does not describe the bridge contracts, upgrade controls, or withdrawal proof model, so a reader cannot confirm its security design from this bundle. No hacks or incidents are mentioned publicly.

Bridges hold pooled user funds in smart contracts, which makes them a common target, and any bridging carries smart-contract risk. The service is run by a team associated with a regulated exchange group, but that does not remove technical risk. The homepage also notes that tokens and NFTs shown on Ink are not endorsed by Ink and are not investment advice.

Who Ink Bridge is for

Ink Bridge is for people who want to use apps on Ink, such as its DEXes and lending markets, and need to move ETH there from Ethereum. It also suits users who trust Kraken's brand and want the chain's official bridge rather than a third-party route. Anyone moving large amounts should verify security details first.

Ink Bridge FAQs

What is Ink Bridge?

Ink Bridge is the bridge that moves assets from Ethereum to the Ink Layer 2 chain. DefiLlama describes it as the bridge for the Ink chain by Kraken and lists it as a canonical bridge.

Who is behind Ink?

Ink describes itself as a Layer 2 built on Optimism's Superchain and released by Kraken. The site footer credits Payward, Inc., which is the company behind Kraken.

What can I bridge with it?

The bridge page shown lets you choose ETH on Ethereum as the source asset and enter a destination address after connecting a wallet. Which other assets and routes are supported is not stated publicly.

How much does it cost to use Ink Bridge?

The project does not publish bridge fees. You would pay Ethereum network gas for the transaction, and any additional costs should appear in the bridge interface before you confirm.

Is Ink Bridge safe?

DefiLlama lists no audits for this entry and the project does not describe the bridge's security design. That is a gap in the information, not proof of a problem, so check Ink's official documentation before sending large amounts.

Does Ink Bridge have its own token?

No. DefiLlama shows no token for the bridge. Public sources mention a points program for some apps in the ecosystem, but nothing about a token for the bridge itself.
