Import USDC Contract to SEI Mainnet

Switching to SEI Mainnet

  1. Click the network icon in the top right corner to switch to SEI Mainnet.

2. Welcome to our Sei v2 Mainnet page!

3. Once connected, click on your balance and then click “Deposit”.

4. To add USDC to SEI, first, link your SEI wallet to EVM via this link

5. The SEI interface is clean and user-friendly. Let’s connect your wallet.

6. Complete the CAPTCHA and wallet signature steps.

7. Now that your SEI address is linked to EVM, return to PredX’s deposit interface to add USDC to the SEI Mainnet.

Add USDC to SEI Mainnet

  1. If your wallet has no USDC on SEI chain, follow these steps to convert other tokens to SEI’s USDC.
  2. Based on the following external article,, I’ll demonstrate how to convert ETH to USDC on SEI:

How to Bridge to SEI (Will provide a detailed example next)

The official SEI Bridge is a reliable platform for bridging assets to SEI. It connects with various Cosmos SDK chains, including Ethereum, Arbitrum, and Osmosis, enabling fast token transfers between networks. The platform supports multiple bridging cryptocurrencies like USDC, ETH, and WBTC.

Steps to Use SEI Bridge:

  1. Access the Sei Bridge website and link your wallet.
  2. Choose the cryptocurrency you intend to send to the SEI Network.
  3. Input the amount you want to bridge and initiate the transfer.
  4. Follow the instructions displayed on your wallet to complete the bridging process, ensuring your assets are successfully transferred.

Example: Converting ETH to USDC on SEI

  1. I will demonstrate using ETH to convert to USDC on SEI.

2. Select ETH as the outgoing currency and SEI’s USDC as the receiving currency on the SEI Bridge.

3. I will use Squid v1 for this demonstration. On this page, choose ETH as the outgoing token and SEI’s USDC as the receiving token. Link your wallet and double-check your wallet address.

4. Click confirm and wait for the transaction to complete. Ensure your wallet has enough SEI tokens (e.g., $1 worth of SEI) for gas fees for subsequent transactions on the SEI network.

5. Verify your token transfer on BaseScan and SEI’s official page. Once SEI’s official page shows you have SEI and USDC tokens, you’re ready for the next step.


When transferring assets to SEI, the main expense you’ll incur is the network gas fees, which fluctuate depending on the activity level of the originating blockchain. The official SEI Bridge does not add any extra charges on top of these gas fees for using its bridging service. To better understand the total costs involved, check the latest gas prices on the blockchain you’re transferring assets from before starting the bridging process to SEI.

As a result, we highly suggest you bridge a few $SEI tokens into your wallet before you actually deposit USDC to our platform in order to avoid any inconvenience or non-smooth experience.

Deposit USDC to PredX

  1. Click the deposit button and follow the instructions in the extension to deposit USDC into your PredX account. Note that, due to legal reasons, IP addresses from mainland China and the United States are prohibited.
