Manta Pacific Wallet: Send ETH and MANTA, Bridge Out Safely

Manta Pacific versus Manta Atlantic

Manta Network runs two different chains. Manta Pacific is the EVM chain with 0x addresses, ETH gas and Ethereum settlement, and it is the one Keylo supports. Manta Atlantic is a separate chain in the Polkadot ecosystem, focused on zero-knowledge identity, with its own address format and its own version of MANTA.

Exchanges sometimes list MANTA on several networks. Withdrawing MANTA to your Keylo address on the wrong network, or to an Atlantic address, will not show up under Manta Pacific in Keylo. Before withdrawing, confirm the exchange's network is Manta Pacific, or the Ethereum network if you prefer to receive an ERC-20 version on Ethereum and bridge yourself.

How Manta Pacific addresses work

Your Manta Pacific address is a standard 0x address derived from your recovery phrase, the same one Keylo shows for Ethereum and every other EVM network. There is no account activation, no minimum balance and no memo, and Keylo validates the address checksum before you send.

Because the address is shared, ETH bridged to Manta Pacific sits at the same address you use on Ethereum, just on a different ledger. If a deposit seems missing, check Ethereum and any other network the sender might have used before assuming anything went wrong.

If you used Manta Pacific with MetaMask or another wallet during its launch campaigns, you can import that recovery phrase into Keylo. Keylo uses the common Ethereum derivation path, so the first account should match. If the address differs, the old wallet may have used a different account, and your balance stays at that original address.

Create a Manta Pacific wallet in Keylo

1. 1

   Go to Keylo registration in any modern browser.

2. 2

   Create your account with name, email, phone and password, then confirm your email.

3. 3

   Keylo creates your 12-word recovery phrase in the browser and encrypts it with a key derived from your password. Only the encrypted copy is stored.

4. 4

   Back up the phrase in Settings after re-entering your password, and keep it offline.

5. 5

   Select Manta Pacific from the network list to see your 0x address and balances.

How to receive ETH or MANTA on Manta Pacific

1. 1

   Open Manta Pacific in Keylo and pick ETH, MANTA or another token.

2. 2

   Tap Receive to show the address, QR code and the Manta Pacific label.

3. 3

   Copy the address for the sender, and specify the Manta Pacific network.

4. 4

   On an exchange, choose Manta Pacific only if it is listed for that asset. Never send to an Atlantic option from a Keylo 0x address.

5. 5

   Check Activity once the sender confirms; transfers usually appear within seconds.

How to send ETH on Manta Pacific

Before sending to an exchange from Manta Pacific, confirm that its deposit page lists Manta Pacific for that exact token. Many exchanges support MANTA only on Ethereum or not at all on Pacific, and deposits on an unsupported network may never be credited.

1. 1

   Select Manta Pacific in Keylo and choose the asset.

2. 2

   Paste or scan the destination address. Keylo checks the checksum and warns when the address is a contract.

3. 3

   Enter an amount or tap Max; Keylo leaves enough ETH for the fee.

4. 4

   Pick a fee speed, then review the network fee and exact amount in the summary.

5. 5

   Confirm to sign the transaction in your browser.

Fees on Manta Pacific

Manta Pacific uses the OP Stack fee model, paid in ETH: an execution fee of gas used times an EIP-1559 base fee plus a priority tip, and a data fee for publishing your transaction. Because the data goes to Celestia rather than Ethereum, the data fee is much smaller than on rollups that post everything to Ethereum, which keeps simple transfers very cheap.

Fees can still rise when the network is busy or when a popular app launches, as the base fee climbs block by block. Keylo shows the exact network fee before you confirm and adds nothing to normal sends. Keep some ETH on Manta Pacific at all times, because tokens such as MANTA cannot pay for their own transfers.

Low fees do not change the cost of leaving. The expensive part of exiting through the official bridge is the Ethereum side: the prove and claim transactions are paid at mainnet gas prices, which can be more than the amount you are withdrawing if the balance is small. For small balances, an exchange that accepts deposits on Manta Pacific, or a liquidity bridge, can be the cheaper way out.

Tokens on Manta Pacific

Manta Pacific supports ERC-20 tokens, which Keylo can show and send. You will typically see MANTA, wrapped ETH, bridged stablecoins such as USDC and USDT, and liquid staking tokens from earlier deposit campaigns. Token contracts on Manta Pacific have their own addresses, so confirm them on the Manta Pacific explorer or the issuer's site before trading.

Old campaign tokens and points-era assets may have little or no liquidity left. Fake MANTA claim sites and airdropped spam tokens also circulate. Ignore tokens you did not expect, never approve contracts linked from token names, and remember that no real claim asks for your recovery phrase.

If you staked or locked MANTA through an app, the position lives in that app's contracts, not as a plain balance at your address. Unstaking usually has its own waiting period set by the app. Check the app's instructions before you plan a move, so a lockup does not catch you by surprise when you want to bridge out.

Moving ETH to and from Manta Pacific without a Keylo bridge

Keylo's swap and bridge routes do not cover Manta Pacific, so use another route. The official Manta Bridge connects Manta Pacific and Ethereum. Deposits arrive after a short wait. Withdrawals follow OP Stack steps: start on Manta Pacific, prove the withdrawal on Ethereum after the next state is posted, then claim on Ethereum once the waiting period of about three days ends, paying mainnet gas for the Ethereum steps.

Third-party liquidity bridges that list Manta Pacific can be faster, and some exchanges accept deposits on the network for specific tokens. The bridges are web apps you connect a browser wallet to; if you import your Keylo recovery phrase into a reputable wallet extension, funds land at the same 0x address shown in Keylo. Once your ETH reaches Ethereum or another supported network, Keylo's swap and bridge works normally.

Send a small test amount through any new route first, and keep ETH on Ethereum if you use the official bridge. Write down the transaction hash of each step, because the official bridge's prove and claim screens are easier to resume when you can look the withdrawal up, and a test makes it clear how long each stage takes before you move more.

Manta Pacific safety tips

• Check exchange support per token before depositing from Manta Pacific.
• Keep ETH on Manta Pacific for gas.
• Understand the trust model: Celestia data and no working fraud proofs yet.
• Use official links for the Manta Bridge, typed yourself, and test small first.
• Compare with full rollups in the Arbitrum guide, and read Keylo security for how your keys are protected.
