safety checklist

Use this checklist before every bridge transaction. It helps you confirm the app, wallet, network, token approval, and gas requirements before moving assets to or from Manta Pacific.

Before You Bridge

Open the official Manta Bridge directly from a trusted source, then review each item below before signing any wallet prompt.

Check	What to Verify	Why It Matters
Official app	The domain, URL spelling, and wallet connection prompt match the official bridge.	Phishing sites can imitate bridge interfaces and request malicious approvals or signatures.
Correct direction	You selected deposit for L1 -> L2, or withdrawal for L2 -> L1.	Deposits and withdrawals use different transaction flows and settlement assumptions.
Correct networks	Your wallet is connected to Ethereum L1 or Manta Pacific as required by the current step.	Signing on the wrong network can fail the transaction or leave funds unmoved.
Correct token	The asset, token symbol, and contract shown in the wallet match what you intend to bridge.	Token symbols can be duplicated; verify the asset before approving or sending.
Token approval	For ERC-20 transfers, the approval amount is expected and scoped to the bridge contract shown.	ERC-20 tokens require allowance before a contract can move them. See ethereum.org's overview of the ERC-20 token standard.
Gas balance	You have enough ETH on the network where you are signing.	ETH is used to pay transaction fees on Ethereum and Manta Pacific. See ethereum.org's explanation of gas and fees.
Test amount	Your first transfer is small.	A small transaction confirms the route, wallet, and token behavior before moving a larger amount.

Wallet Review

Before confirming, read the wallet prompt carefully:

1. Confirm the connected account is the account that should receive the bridged funds.
2. Confirm the transaction type matches your intent: approval, deposit, or withdrawal.
3. Confirm the token and amount are correct.
4. Confirm the network shown in the wallet matches the bridge step.
5. Reject the prompt if the spender, amount, network, or token looks unfamiliar.

For wallet setup and network switching help, see the wallet guide.

Deposits

For deposits from Ethereum L1 to Manta Pacific:

• Keep ETH on Ethereum L1 for the deposit transaction.
• If bridging an ERC-20 token, expect an approval transaction before the deposit transaction.
• Wait for the bridge interface and wallet to show the transaction status before starting another transfer.
• Verify live fees and transaction details in the app before confirming.

Withdrawals

For withdrawals from Manta Pacific to Ethereum L1:

• Keep ETH on Manta Pacific for the withdrawal transaction.
• Understand that withdrawals follow the rollup exit model and may require additional steps before funds are available on L1.
• Do not rely on estimated times from third-party posts; verify the current withdrawal flow in the bridge interface.
• Review ethereum.org's overview of optimistic rollups for background on rollup withdrawal mechanics.

Stop and Recheck If

Do not continue if:

• The URL was opened from an unsolicited message, ad, or unknown search result.
• Your wallet asks for an unlimited approval you did not expect.
• The transaction requests a different token or network than the bridge page shows.
• The bridge page, wallet, or block explorer shows inconsistent amounts.
• You are unsure whether you are depositing or withdrawing.
