This page covers wallet connection, Manta Pacific network setup, token approvals, and basic safety checks. ## Before you connect Use a wallet that supports Ethereum-style EVM networks, such as MetaMask or another compatible wallet. Manta Pacific is an Ethereum L2, so your Manta Pacific address is normally the same address as your Ethereum account, but balances and transaction history are network-specific. Before bridging, confirm: * You control the wallet account you plan to use. * You are using official bridge and network information. * You understand whether you are depositing to Manta Pacific or withdrawing back to Ethereum. * You have ETH available on the source network for gas. For a broader pre-transaction review, use the [safety checklist](file:///2078213/security/safety-checklist.md). ## Connect your wallet 1. Open the bridge interface from an official source. 2. Select **Connect wallet**. 3. Choose your wallet provider. 4. Confirm the site origin in the wallet prompt. 5. Select the account you want to use. 6. Approve the connection only if the domain and requested account are correct. Connecting a wallet lets the app read your public address and request transaction signatures. It does not, by itself, move funds or approve token spending. ## Add Manta Pacific Your wallet needs Manta Pacific configured before it can show L2 balances or submit L2 transactions. If your wallet prompts you to add or switch networks, review the network name, RPC URL, chain ID, currency symbol, and explorer URL against official Manta sources before approving. For step-by-step MetaMask setup, follow [Add Manta Pacific to MetaMask](file:///2078213/guides/add-manta-pacific-to-metamask.md). {% hint style="info" %} Adding a network only changes wallet configuration. It does not bridge assets between Ethereum and Manta Pacific. {% endhint %} ## Keep ETH for gas ETH is the gas token for transactions on Manta Pacific. You may need ETH on: | Action | Where ETH may be needed | | -------------------------------------- | ----------------------------------------------------------------------------------------- | | Deposit from Ethereum to Manta Pacific | Ethereum mainnet, to submit the deposit transaction | | Use assets on Manta Pacific | Manta Pacific, to pay L2 transaction gas | | Withdraw from Manta Pacific | Manta Pacific for the withdrawal transaction, and potentially Ethereum for later L1 steps | | Approve an ERC-20 | The network where the approval transaction is submitted | Gas costs change with network conditions. Check the live transaction preview in your wallet before signing. ethereum.org explains how [gas and transaction fees](https://ethereum.org/developers/docs/gas/) work on Ethereum-style networks. ## Review token approvals ERC-20 token transfers usually require an approval before the bridge contract can move the token from your wallet. This is a separate transaction from the bridge transfer. When approving a token: 1. Confirm the token symbol and contract address. 2. Confirm the spender is the expected bridge contract. 3. Review the approval amount. 4. Avoid approving from the wrong network or account. 5. Revoke or reduce approvals you no longer need. See [Token Approvals](file:///2078213/guides/token-approvals.md) for a dedicated approval workflow. For background, ethereum.org provides an overview of the [ERC-20 token standard](https://ethereum.org/developers/docs/standards/tokens/erc-20/). ## Transaction prompts Read each wallet prompt before signing: * **Connect**: allows the app to see your address. * **Switch network**: changes the active wallet network. * **Add network**: saves a new network configuration. * **Approve token**: lets a contract spend a specified ERC-20 amount. * **Deposit or withdraw**: submits the bridge transaction. Deposits move assets from Ethereum L1 to Manta Pacific L2. Withdrawals follow the rollup exit model, so review the bridge interface and wallet prompts carefully before starting. The OP Stack documentation describes the [standard bridge model](https://docs.optimism.io/app-developers/bridging/standard-bridge) used by OP Stack chains. ## Wallet safety checklist Before signing, verify: * The active network matches the action you are taking. * The account address is correct. * The asset, amount, destination, and direction are correct. * You have enough ETH for gas after the transfer. * Token approvals are limited to what you intend to use. * The transaction preview matches the bridge action you selected. If anything looks unexpected, reject the wallet prompt and re-check the setup before trying again. --- # Agent Instructions This documentation is published with GitBook.
