ActiveMantle Bridge Review 2026: Official Ethereum–Mantle Route
Mantle Bridge is the official app for moving tokens between Ethereum and the Mantle Layer-2 network, with about $115 million in TVL on DefiLlama. It is the standard route into Mantle, but public sources published here say little about fees or audits.

Our verdict on Mantle Bridge
6.8/10Mantle Bridge is the official way to move tokens between Ethereum and the Mantle Layer-2, and it holds about $115 million in TVL. It suits anyone who already plans to use Mantle and wants the network's own bridge rather than a third party. The main caveat is the lack of published detail: no audits listed on DefiLlama, and no fee or withdrawal-time information, so check Mantle's documentation before moving large sums.

What is Mantle Bridge?
Mantle Bridge is the official app for moving tokens between Ethereum and Mantle Network, an Ethereum Layer-2 scaling network. DefiLlama classes it as a canonical bridge and shows about $114.9 million in TVL, down 1.7% over seven days.
The interface is simple: a From and To selector set to Ethereum and Mantle, a token selector, an amount field and a Connect Wallet button. Bridge History and FAQ tabs sit at the top, and Get MNT and Get Gas shortcuts help new users prepare for using the network. The homepage says it is also for testing dApps deployed on Mantle.
The network's token is MNT. Public sources list no audits on DefiLlama and do not state fees, supported token lists or withdrawal times, so this review stays at the level of what is published.
How Mantle Bridge works
A canonical bridge is the official channel between a Layer-1 and its Layer-2. A user sends tokens from Ethereum to a bridge contract, and the same value becomes available on Mantle. Moving back reverses the process, so tokens leave Mantle and are released on Ethereum.
Mantle Network is described by DefiLlama as a Layer-2 scalability solution built on Ethereum. The bridge app is the user-facing front end: connect a wallet, pick a route and token, and sign the transactions.
The project does not describe the technical details, such as withdrawal delay or the security model. Newcomers should read Mantle's documentation on these points before moving large amounts.

Pros and cons
What we like
- Official canonical bridge for Mantle Network, so it is the expected entry route for the L2.
- About $115 million in TVL on DefiLlama signals real usage.
- Clean interface with only a From, To, token and amount flow.
- Bridge History and FAQ are available in the app.
- Get MNT and Get Gas shortcuts help new users prepare to use the network.
Watch out for
- No audits are listed on DefiLlama for this bridge, and the project does not link to any audit reports.
- Its homepage shows little detail on fees, withdrawal times or supported tokens before a wallet is connected.
- Canonical bridges carry smart-contract risk, and funds locked in bridge contracts are a concentrated target.
- Public sources name only Ethereum as the connected chain, so it does not cover other networks.
- Value depends on Mantle Network itself; users who do not use that L2 have no reason to use it.
Mantle Bridge fees
Fees are not published. Its homepage shows no fee schedule, so users would see the estimated cost in the bridge interface after connecting a wallet and entering an amount.
As with most Ethereum bridges, expect to pay Ethereum network gas for a deposit. Any additional bridge or withdrawal costs should be confirmed in the app and its FAQ before approving a transaction.
Is Mantle Bridge safe?
DefiLlama lists zero audits for this bridge, and public sources contain no audit reports, incident history or description of the security model. That does not prove the code is unaudited, but it is something readers should check in Mantle's own documentation.
Canonical bridges hold large pools of locked assets, which makes them attractive targets, and users depend on the bridge contracts and the L2's security design. Always confirm that you are on the official app address, because fake bridge sites are a common scam. Only bridge amounts you can afford to risk.
6 steps
How to get started with Mantle Bridge
- 1
Open the official Mantle bridge app from Mantle's own website or a link you trust, and check the address carefully.
- 2
Connect an Ethereum-compatible wallet using the Connect Wallet button.
- 3
Confirm that the From network is Ethereum and the To network is Mantle.
- 4
Select the token and enter the amount you want to bridge.
- 5
Review the gas estimate and any warnings in the interface, then approve the transaction in your wallet.
- 6
Track the transfer in the Bridge History tab, and use Get Gas if you need funds for fees on Mantle.
Who Mantle Bridge is for
Mantle Bridge is for users and developers who want to use Mantle Network and need to move assets from Ethereum. It also suits developers testing dApps deployed on Mantle. It is less relevant for people who never touch that network or want routes to other chains.
Mantle Bridge FAQs
What is Mantle Bridge?
It is the official bridge for moving tokens between Ethereum (Layer 1) and Mantle Network, an Ethereum Layer-2. DefiLlama lists it as a canonical bridge, meaning the network's own bridge rather than a third-party service.
Which tokens and chains does Mantle Bridge support?
The homepage shows Ethereum to Mantle as the route shown, with a token selector and a Connect Wallet button. Which tokens are supported is not listed in the page text, so check the token selector after connecting a wallet.
What are the Get MNT and Get Gas buttons?
The page offers Get MNT and Get Gas shortcuts. MNT is the token DefiLlama associates with Mantle, and gas on the network is something users need to pay for transactions. Details of how each shortcut works are not given publicly.
How much does it cost to use Mantle Bridge?
Fees are not published publicly. Bridging from Ethereum generally involves an Ethereum network gas fee, and withdrawals from L2s often take longer than deposits. Check the interface and the FAQ section before confirming a transaction.
Is Mantle Bridge safe?
DefiLlama lists no audits for it, and public sources include no audit reports, so users should look for Mantle's own security documentation. Any bridge carries smart-contract risk, so avoid bridging more than you are willing to risk.
Can I see my past transfers?
Yes. The app has a Bridge History tab, though the page text does not describe what it shows in detail. It is presumably where users track past transfers.
