Bridging USDC to Circle's Arc Mainnet: A Step-by-Step Guide

Circle's Arc Mainnet, an EVM-compatible Layer 1 chain, allows users to transact using USDC for both payments and transaction fees. This means that if you're moving USDC to Arc, you won’t need a separate gas token; your USDC can cover the gas costs directly.

Essential Considerations Before Bridging

Before you initiate a transfer, it's vital to consult Arc's gas documentation. For transferring ERC-20 tokens, expect a design target fee of approximately 0.001 USDC, although the final fee can vary based on network conditions and the specifics of your transaction. Always ensure you retain enough USDC on Arc to cover gas fees post-transfer.

The mechanics of bridging are distinct from Arc's in-network transaction speeds. While transfers within Arc are swift, cross-chain transactions can take longer as they depend on the processing speed of the source chain.

Be cautious: Anyone can engage with the Arc network, which includes deploying applications and making transactions. This openness can attract malicious actors, so stay vigilant against potential scams.

Bridging USDC to Arc Using Zerion Wallet

Zerion’s Bridge offers a helpful feature, allowing you to compare routes from various providers without needing to visit each individually. Here’s how you can perform the bridge operation:

Via Zerion Web App

1. Open the bridging section in the Zerion web app and connect your wallet.
2. Select your source network and choose Arc as the destination.
3. Enter the token and amount you wish to send, and select USDC for the receive option.
4. Review the estimated received amount, fees, and time. Approve token access if necessary.
5. Click Sign and Send to finalize the transaction.

After executing these steps, your assets should appear on Arc within seconds to a few minutes, depending on the source chain's efficiency.

Using Zerion Wallet on Mobile

1. Launch Zerion and tap the swap button.
2. Select the source network and asset under “Pay with”.
3. In “Receive”, tap the globe icon, type “Arc”, and choose it.
4. Check your quote and approve token access when prompted.
5. Tap Swap now, followed by Confirm to complete the process.

Note the estimated time displayed for your transaction path. While Arc operates quickly, the source chain could introduce delays.

Checking Your Arc Balance

Once portfolio support for Arc is activated, your assets on that network will display alongside holdings from other networks in the Zerion interface.

Use the filter option to specifically view your Arc assets, and open the transaction history to track incoming tokens.

To send USDC from Arc, select it, input the recipient's details, and review the transaction. Remember, the fee will be deducted from your USDC balance, so make sure to leave enough to cover it.

Data Integration with Zerion

Zerion's API is set to offer Arc coverage right from the start, encompassing balances, pricing, transaction history, and webhooks. This integration provides builders with valuable data without requiring them to maintain their own node or chain indexer. Secure a free Zerion API key to experience these capabilities firsthand.
