# Migrate your USDC.n to USDC.inj

> Migrate USDC.n to USDC.inj manually with Skip:Go, before the one-step migration.

Use this guide to migrate **USDC.n to USDC.inj** with [Skip:Go](https://go.skip.build/).

## Why this migration is needed

<Frame>
  <img src="https://mintcdn.com/skip-go/jO4YGzxyzS8I510F/images/usdc-migration-001.png?fit=max&auto=format&n=jO4YGzxyzS8I510F&q=85&s=1d1a3fc619b0af195514f96d1bde6245" alt="USDC.n is being deprecated in favor of USDC.inj" width="1672" height="941" data-path="images/usdc-migration-001.png" />
</Frame>

**USDC.n is being deprecated** and will no longer be the supported version of USDC on the chains covered by this guide. If you hold USDC.n, you should migrate it to **USDC.inj**, the version that will be supported going forward.

### What are the differences between USDC.n and USDC.inj?

Both are USDC, but they originate from different chains and are treated as separate assets on Cosmos chains.

* **USDC.n:** USDC originating from Noble
* **USDC.inj:** USDC originating from Injective

***

## What happens when you migrate

<Frame>
  <img src="https://mintcdn.com/skip-go/jO4YGzxyzS8I510F/images/usdc-migration-002.png?fit=max&auto=format&n=jO4YGzxyzS8I510F&q=85&s=c43d7afbf0806c9a0f8197499788dc7b" alt="Two-stage overview of the USDC.n to USDC.inj migration" width="1672" height="941" data-path="images/usdc-migration-002.png" />
</Frame>

After the migration, you will have **USDC.inj on the same chain where you started**.

For example:

`dYdX USDC.n → dYdX USDC.inj`

Skip:Go routes the migration through Injective. You do not need to send your funds to Injective manually.

***

## Who this guide applies to

This guide applies to USDC.n held on:

* dYdX, Cosmos Hub, Osmosis, Terra, Neutron, ZIGChain

If your USDC.n is on a chain not listed above, check whether **Skip:Go provides a route to transfer it to one of the supported chains listed above**. If a route is available, transfer your USDC.n to that chain first, then follow this migration guide.

If no supported route is available, contact the team responsible for your chain.

**For chain teams:** See [What if my USDC.n is on a chain not listed above?](#what-if-my-usdc-n-is-on-a-chain-not-listed-above) in the FAQ below for the requirements and process to add support.

<Warning>
  **dYdX users**

  This guide applies only to USDC.n held in your **dYdX Chain wallet**.

  It does not apply to USDC in a **dydx.trade trading subaccount**. Follow the official dYdX migration instructions for that balance when they become available.
</Warning>

***

## What to do

Manual migration will be available starting **August 28, 2026**.

A simpler one-step migration is planned for **Mid-September, 2026**.

| Details                             | Manual migration                                  | One-step migration                  |
| ----------------------------------- | ------------------------------------------------- | ----------------------------------- |
| Availability                        | **From August 28, 2026**                          | **Planned for mid-September, 2026** |
| Migration stages                    | 2                                                 | 1                                   |
| Wallet signatures                   | 3                                                 | 2                                   |
| Networks requiring transaction fees | Source chain, selected EVM network, and Injective | Source chain only                   |

<Note>
  The signature counts above only cover the migration itself and exclude any transactions needed to
  obtain fee tokens.
</Note>

***

## Before you start

The manual migration has **two stages**:

**Stage 1:** USDC.n on your source chain → USDC on an EVM network

**Stage 2:** EVM USDC → Injective → USDC.inj on the chain where you started

This guide uses **dYdX** as the source chain and **Avalanche** as the EVM network.

If your USDC.n is on another supported source chain, select that chain instead. The overall migration flow is the same.

<Warning>
  **Stay safe**

  Use only the official Skip:Go site at **go.skip.build**. Never share your seed or recovery phrase.
</Warning>

### 1. Prepare gas

<Frame>
  <img src="https://mintcdn.com/skip-go/jO4YGzxyzS8I510F/images/usdc-migration-003.png?fit=max&auto=format&n=jO4YGzxyzS8I510F&q=85&s=f6b0746c7357eed2c8f195af29afa5e4" alt="Preparing gas on the source chain, EVM network, and Injective" width="1586" height="992" data-path="images/usdc-migration-003.png" />
</Frame>

The manual migration requires transaction fees on **three networks**:

1. Your **source chain**
2. Your selected **EVM network**
3. **Injective**

Make sure you have the required fee tokens on all three networks before starting.

#### Source chain

Keep approximately **\$0.10 worth of a supported fee token** on the chain where your USDC.n is held.

| Source chain | Common fee token |
| ------------ | ---------------- |
| dYdX         | DYDX             |
| Cosmos Hub   | ATOM             |
| Osmosis      | OSMO             |
| Terra        | LUNA             |
| Neutron      | NTRN             |
| ZIGChain     | ZIG              |

#### EVM network

You also need gas on the EVM network used for the migration.

| EVM network   | Gas token | Approx. fee per transaction | Recommended gas balance |
| ------------- | --------- | --------------------------- | ----------------------- |
| **Avalanche** | AVAX      | **\~\$0.01**                | **\~\$0.10**            |
| Optimism      | ETH       | \~\$0.10                    | **\~\$0.50**            |
| Base          | ETH       | \~\$0.23                    | **\~\$1.00**            |
| Arbitrum      | ETH       | \~\$0.37                    | **\~\$1.00**            |
| Polygon       | POL       | \~\$0.43                    | **\~\$1.00**            |
| Ethereum      | ETH       | \~\$0.70                    | **\~\$3.00**            |

You can use another supported EVM network if you prefer or already have gas there.

#### Injective

You need **INJ** to pay the Injective transaction fee in Stage 2.

| Gas token | Approx. fee per transaction | Recommended gas balance   |
| --------- | --------------------------- | ------------------------- |
| INJ       | \~0.0025 INJ (\~\$0.01)     | **\~\$0.10 worth of INJ** |

<Note>
  Fees are estimates and may vary with network conditions. Recommended balances include extra
  buffer.
</Note>

### 2. Check your wallets and addresses

Before starting, make sure you can access:

* The wallet holding your **USDC.n**
* A wallet on your selected **EVM network**
* An **Injective address with INJ** for gas
* An address on your original source chain to receive **USDC.inj**

Your source and destination addresses may be in the same wallet, and the same wallet may support more than one of these networks.

This guide uses **Keplr** for dYdX and Injective. For the EVM network, use a wallet supported by Skip:Go.

<Warning>
  Select each address from a wallet that supports that network. Do not manually convert one address
  format into another.
</Warning>

***

## Stage 1: Move USDC.n to an EVM network

**dYdX USDC.n → Avalanche USDC**

* **Wallet signatures:** 1
* **Estimated time:** Up to 6 minutes

<Steps>
  <Step title="Select USDC.n and enter the amount">
    <Frame>
      <img src="https://mintcdn.com/skip-go/jO4YGzxyzS8I510F/images/usdc-migration-004.png?fit=max&auto=format&n=jO4YGzxyzS8I510F&q=85&s=05ea333bdb6e2f734e3dda460dcbe114" alt="Selecting USDC.n as the source asset and entering the migration amount" width="1672" height="941" data-path="images/usdc-migration-004.png" />

    </Frame>

    Check:

    * **From:** dYdX / USDC.n
    * **To:** Avalanche / USDC
    * **Amount**
    * **Destination address**

    Approve the transaction in your source wallet.

    **Signature 1 of 3**
  </Step>

  <Step title="Wait for the transfer">
    Skip:Go will track the transfer automatically.

    **Keep this page open** while the transfer is in progress.
  </Step>

  <Step title="Complete Stage 1">
    When Skip:Go displays **Go again**, Stage 1 is complete.

    Your USDC is now on Avalanche.

    Continue to **Stage 2** to migrate it to **USDC.inj on your original source chain**.
  </Step>
</Steps>

***

## Stage 2: Move EVM USDC to USDC.inj on your source chain

**Avalanche USDC → Injective → dYdX USDC.inj**

* **Wallet signatures:** 2

<Steps>
  <Step title="Select USDC and USDC.inj">
    <Frame>
      <img src="https://mintcdn.com/skip-go/jO4YGzxyzS8I510F/images/usdc-migration-006.png?fit=max&auto=format&n=jO4YGzxyzS8I510F&q=85&s=710d2cbffa468b9756960eeffe20204a" alt="Selecting Avalanche USDC as the source and dYdX USDC.inj as the destination" width="1586" height="992" data-path="images/usdc-migration-006.png" />
    </Frame>

    In Skip:Go, select:

    * **From:** Avalanche / USDC
    * **To:** dYdX / USDC.inj

    Enter the amount you want to migrate.

    If your migration started on another supported source chain, select that **same chain** as the destination.

    <Warning>
      Make sure the destination asset is **USDC.inj**, not USDC.n.
    </Warning>
  </Step>

  <Step title="Review and confirm">
    Check:

    * **From:** Avalanche / USDC
    * **To:** dYdX / USDC.inj
    * **Amount**
    * **Destination address**

    Select **Confirm**.
  </Step>

  <Step title="Continue to signing">
    Skip:Go will display **2 signatures required**.

    Select **Continue** and keep the window open until both signatures are complete.
  </Step>

  <Step title="Complete both signatures">
    <Frame>
      <img src="https://mintcdn.com/skip-go/jO4YGzxyzS8I510F/images/usdc-migration-007.png?fit=max&auto=format&n=jO4YGzxyzS8I510F&q=85&s=75e654de901251fe15fd2262d6154c4e" alt="Approving both required signatures to complete Stage 2" width="1584" height="993" data-path="images/usdc-migration-007.png" />
    </Frame>

    Approve both transactions when prompted:

    1. **Injective transaction** → uses INJ for the transaction fee
    2. **Avalanche transaction** → uses AVAX for the transaction fee

    Review each transaction before approving it.
  </Step>

  <Step title="Wait for the migration">
    After both transactions are approved, Skip:Go will process the migration.

    **Keep this page open** while the migration is in progress.
  </Step>

  <Step title="Confirm completion">
    When Skip:Go displays **Go again**, the migration is complete.

    Confirm that **USDC.inj is available on dYdX**.

    **Migration complete:**

    `dYdX USDC.n → dYdX USDC.inj`
  </Step>
</Steps>

## FAQ

<AccordionGroup>
  <Accordion title="I use dydx.trade. Should I use this guide?">
    Only if you also hold **USDC.n directly in your dYdX Chain wallet**.

    Do not use this guide for USDC in a **dydx.trade trading subaccount**. Follow the official dYdX migration instructions for that balance when they become available.
  </Accordion>

  <Accordion title="What if I stop during the manual migration?">
    You can resume the migration later.

    * **After Stage 1:** Your USDC remains on the EVM network you selected. You can start Stage 2 later using that USDC.
    * **During Stage 2 signing:** Both signatures are required before Stage 2 proceeds. If you stop before completing both signatures, your USDC remains on the EVM network. You can start Stage 2 again when you are ready.

    For example, if you use Avalanche, your USDC remains on **Avalanche** until Stage 2 proceeds.
  </Accordion>

  <Accordion title="Is USDC.n → USDC.inj a swap?">
    This guide is specifically for migrating your balance from **USDC.n to USDC.inj**.

    Skip:Go may display **Swap** in parts of the interface because the same interface is also used for swaps and cross-chain transfers.

    Swapping USDC.n for another token, such as DYDX, AVAX, or INJ, is a separate transaction and is not part of this migration.
  </Accordion>

  <Accordion title="Do I need to migrate before mid-September?">
    No. **Mid-September is the planned launch date for the one-step migration, not a migration deadline.**

    Manual migration will be available starting **August 28, 2026**. You can use the manual flow or wait for the one-step migration planned for mid-September.
  </Accordion>

  <Accordion title="Do I have to use Avalanche?">
    No.

    This guide uses Avalanche as an example; you can use any supported EVM network.

    If you choose another network, make sure you have the required gas token before you start.
  </Accordion>

  <div id="what-if-my-usdc-n-is-on-a-chain-not-listed-above" />

  <Accordion title="What if my USDC.n is on a chain not listed above?">
    If your USDC.n is on a chain not listed above, check whether **Skip:Go provides a route to transfer your USDC.n to one of the supported chains listed above**. If a route is available, transfer your USDC.n to that supported chain first, then follow this migration guide.

    If no supported route is available, contact the team responsible for your chain.

    **For chain teams:** A direct IBC path with Injective is required to support your chain as a USDC.inj destination, including **IBC light clients, an ICS-20 transfer channel, and at least one reliable relayer**.

    If you need help meeting these requirements and already have a Skip contact, work with them for guidance and assistance.

    Once the IBC connection and relaying are operational, use your existing contact with Skip or submit a **Chain Integration Request** to request support for your chain as a USDC.inj destination on Skip:Go.
