What are the Manta bridge contract addresses?

What is the Manta bridge deposit (portal) contract?

The deposit-side portal contract is the OptimismPortal at 0x9168765EE952de7C6f8fC6FaD5Ec209B960b7622 on Ethereum Mainnet.

This is the Ethereum-side portal and ETH escrow contract for Manta Pacific deposits. In practical terms, it is the address users should recognize when the native route is moving ETH from Ethereum into the Manta Pacific rollup path.

Verify the full address, the contract label, and the proxy or implementation details on Etherscan's OptimismPortal page before treating any wallet prompt as genuine.

What is the ERC-20 bridge contract?

The Ethereum ERC-20 bridge contract is the L1StandardBridge at 0x3B95bC951EE0f553ba487327278cAc44f29715E5.

This address is the L1-side contract used for ERC-20 token bridging between Ethereum Mainnet and Manta Pacific. If a wallet approval asks you to approve a different spender, stop and compare it against the official route and the explorer page.

The authoritative explorer check is Etherscan's L1StandardBridge page. Do not approve tokens based only on a shortened address, a UI nickname, or a copied social-media post.

What is the MANTA token contract?

The MANTA token contract address is 0x95CeF13441Be50d20cA4558CC0a27B601aC544E5 on Ethereum and Manta Pacific.

The same address on both chains makes visual checks easier, but it does not remove the need to verify the chain. A token address copied from Ethereum is not enough if the wallet is connected to the wrong network or if a fake site is asking for a malicious approval.

How do you verify these on Etherscan?

Use Etherscan as a verification step, not as a shortcut: compare the full address, contract label, chain, proxy details, and wallet prompt before signing.

1. Start from the official routeOpen the bridge from official Manta documentation or another trusted Manta source, then compare the address shown in your wallet with the contract table above.

2. Match the full addressDo not rely on the first and last characters only. Copy and compare the complete mixed-case address.

3. Check the chainOptimismPortal and L1StandardBridge are Ethereum Mainnet contracts. MANTA exists on Ethereum and Manta Pacific at the address listed above.

4. Read the explorer labelLook for the known contract name or token label, plus source/proxy information where the explorer exposes it.

5. Inspect approvalsFor ERC-20 transfers, confirm the spender is the bridge contract you intended to approve and avoid unlimited approvals unless you explicitly want them.

6. Cross-check risk contextUse L2BEAT's Manta Pacific profile for the architecture and upgrade-risk view.

Facts last verified: July 2, 2026. Explorer pages and L2BEAT can change, so re-check the live pages before any meaningful transfer.

Why does L2BEAT list Manta contracts as unverified/upgradeable?

L2BEAT is flagging project-level transparency and upgrade risk, not saying that every address in this table is fake.

The honest interpretation is that Manta Pacific uses a system with upgrade controls and risk assumptions that users should understand. Upgradeability can be normal for live L2 infrastructure, but it means users should watch who can upgrade contracts, what delay or control exists, and whether the contract source and implementation are easy to inspect.

That is why contract checks should sit next to broader route checks. For a risk-first view, read bridge safety. For route identity, compare official vs third-party before deciding which path to use.

Use the contract list before you bridge

The safest workflow is simple: open the official app, verify the relevant contract address, then sign only the transaction you expected.

If you are moving ETH or ERC-20 tokens between Ethereum and Manta Pacific, keep this page open beside your wallet. When you are ready, open Manta Bridge, compare the prompt, and use all Manta Bridge guides if you need the route, timing, or withdrawal background.

Before signing: the address, chain, spender, token, and destination should all match your intended bridge action. If any one of those differs, reject the prompt and restart from a trusted path.

Where do I find official addresses?

Start with the official Manta Network documentation and then verify the exact address on the relevant block explorer before signing. For the Ethereum-side bridge, the key addresses are the OptimismPortal and L1StandardBridge listed on this page.

Is MANTA the same on Ethereum and Pacific?

Yes. The MANTA token address listed in the Manta documentation is 0x95CeF13441Be50d20cA4558CC0a27B601aC544E5 on both Ethereum and Manta Pacific. Still check that your wallet is connected to the chain you intend to use.

Why does L2BEAT say unverified or upgradeable?

L2BEAT flags verification and upgrade risk at the project risk level. That means users should not treat contract labels as a guarantee; they should verify explorer pages, proxy implementations, and official docs before interacting.

How do I avoid a fake contract?

Do not copy an address from a social post, ad, or wallet popup. Compare the full address against Etherscan, official Manta documentation, and the official bridge app route before approving tokens.

What is the OptimismPortal?

The OptimismPortal is the Ethereum-side portal and ETH escrow contract used by OP Stack style bridges. For Manta Pacific, the address listed here is 0x9168765EE952de7C6f8fC6FaD5Ec209B960b7622.
