# USDC Migration Guide

USDC Migration on Sei: USDC.n to USDC

## Overview

On Sei Mainnet, there are currently **two types of USDC**:

* **USDC.n**: The IBC-enabled version of USDC, issued by Circle on the Noble chain and bridged to Cosmos-based chains like Sei.
* **USDC**: Native USDC on Sei is the official version of USDC directly issued by Circle to Sei via CCTP

Both are usable today, but **USDC is becoming the new standard** across the Sei DeFi ecosystem.

## Understanding the Difference

| Feature              | USDC                                         | USDC.n                       |
| -------------------- | -------------------------------------------- | ---------------------------- |
| Origin               | Native USDC on Sei                           | Bridge from Noble            |
| Bridging Method      | Circle CCTP                                  | IBC                          |
| Cross-Chain Support  | Native CCTP support (Ethereum, Solana, etc.) | Limited to Cosmos IBC chains |
| Ecosystem Preference | Preferred                                    | Deprecated                   |

### Why migrate to USDC?

Protocols on Sei (including Yei Finance) are adopting **USDC** as the primary stablecoin for the following reasons:

* USDC is issued directly by Circle, ensuring official backing and credibility.
* USDC supports native cross-chain transfers via Circle’s CCTP.
* It has stronger oracle, analytics, and developer tooling support.
* Integrating USDC into DeFi protocols is simpler and safer.

**USDC** will be the default stablecoin on Sei, offering better native liquidity and security. As Sei transitions to EVM-only, **USDC.n will no longer be supported.**

### How to migrate?

You can migrate to native USDC using the following three methods:

<details>

<summary><strong>Method 1</strong> – YeiBridge</summary>

**Suitable for most users. Convenient and secure, but users should watch for bridge caps and fees.**

YeiBridge also integrates with the third-party bridge Stargate. Be sure to check caps and fees before bridging.

* **Use YeiBridge to migrate.**

  * Visit [YeiBridge](https://app.yei.finance/bridge/) to send your USDC.n to another chain (such as Avalanche, Arbitrum) as USDC.

  * Then bridge the USDC back to Sei as native USDC.

  * If you don’t see native USDC in your wallet, you can add the Sei USDC token address [here](https://app.yei.finance/reserve-overview/?underlyingAsset=0xe15fc38f6d8c56af07bbcbe3baf5708a2bf42392\&marketName=sei_mainnet_1) and click “**Add token to wallet**,” then select USDC.

  * Make sure you have enough assets (such as AVAX or ETH) on the destination chain to cover transaction fees to bridge back.

<summary><strong>Method 2</strong> – CCTP via Skip:Go Bridge</summary>

**Suitable for large transfers to avoid slippage, but requires more steps and may take longer.**

This method is better for large amounts, offering zero slippage from Sei back to Noble (as of July 24, 2025). It leverages CCTP but requires additional setup, such as configuring a Keplr wallet.

* **Use CCTP via Skip:Go Bridge to migrate.**
  * **Transfer USDC onto your Keplr wallet.**
    * **Option 1:** Send USDC.n from your **Sei EVM wallet** to your **Keplr wallet.**

      * Go to <https://app.sei.io/> and link your Cosmos wallet to retrieve your EVM address.

      ![](https://content.gitbook.com/content/AVHC81FYBgMAILvctkBu/blobs/1FH6MeWFZisHUOWQWQxg/image)
    * **Option 2: Import the private key from your Sei EVM wallet into Keplr wallet.**
  * **Navigate to Skip:Go Bridge.**

    * Visit [Skip:Go Bridge](https://go.skip.build/), and bridge USDC.n from Sei-EVM to your desired EVM chain. Make sure the bridge cross through Noble before confirming the transaction to avoid slippage.

    ![](https://content.gitbook.com/content/AVHC81FYBgMAILvctkBu/blobs/XFIRxVRtExLp10orrJjc/image)

    * Wait for the bridge to complete and confirm USDC in your wallet.
  * Bridge native USDC back.

    * Visit [YeiBridge](https://app.yei.finance/bridge/)to bridge native USDC back to Sei.

    ![](https://content.gitbook.com/content/AVHC81FYBgMAILvctkBu/blobs/FU5pciXtpjsySw72Q3XA/image)
  * Make sure you have enough assets (such as AVAX or ETH) on the destination chain to cover transaction fees to bridge back.

<summary><strong>Method 3</strong> - YeiSwap</summary>

**Fastest method. Ideal for smaller amounts. Be aware of potential slippage.**

Make sure to have Sei token in your wallet to pay for the transaction.

* **Swap on YeiSwap.**
  * Visit [YeiSwap](https://swap.yei.finance/) to convert assets into USDC directly on Sei.

## Frequently Asked Questions

<details>

<summary><strong>Q: Do I have to migrate?</strong></summary>

A: Migration is strongly recommended. As Sei transitions to an EVM-only architecture, USDC.n will have fewer use cases and reduced support across the ecosystem. Yei Finance will disable deposits and borrowing for USDC.n after **Sep 1, 2025**.

</details>

<details>

<summary><strong>Q: Is USDC.n going away?</strong></summary>

A: Once Sei completes the SIP-3 transition, Cosmos-native assets will no longer be supported. For more details, see: [https://blog.sei.io/sip-3-update-sei-moves-toward-evm-only-architecture](https://blog.sei.io/sip-3-update-sei-moves-toward-evm-only-architecture/?utm_source=chatgpt.com).
