# USDC on Injective

> USDC stablecoin contract addresses, CCTP integration details, and testnet faucet information for building with USDC on Injective.

USDC is available on Injective as a **native stablecoin** through
[Circle's Cross-Chain Transfer Protocol (CCTP)](https://www.circle.com/cross-chain-transfer-protocol).
USDC on Injective implements the [MultiVM Token Standard (MTS)](/developers-evm/multivm-token-standard),
which means the same token is accessible across both the EVM and Cosmos protocols on Injective networks, without bridging.

You can use USDC for trading on Injective's on-chain order book, as collateral for derivatives markets,
for cross-chain transfers via CCTP, and as a settlement currency in DeFi applications built on Injective.

Try this out hands-on in our [USDC CCTP Tutorial](/developers-defi/usdc-cctp-tutorial).

## Frequently asked questions

<Accordion title="What is USDC on Injective?">
  USDC on Injective is a native deployment of Circle's USD Coin stablecoin.
  It is backed 1:1 by US dollar reserves held by Circle and is transferred to Injective through the Cross-Chain Transfer Protocol (CCTP).
  USDC on Injective follows the MultiVM Token Standard (MTS),
  making it usable across both the EVM and Cosmos protocols of the Injective blockchain network.
</Accordion>

<Accordion title="Where can I verify the smart contract addresses for USDC, and USDC CCTP?">
  The information provided above is for your convenience only.
  You should always consult Circle's documentation as the *canonical source* for smart contract addresses,
  and USDC CCTP domain IDs.

  References:

  * [USDC smart contract addresses](https://developers.circle.com/stablecoins/usdc-contract-addresses)
  * [USDC CCTP smart contract addresses for EVM-compatible blockchains](https://developers.circle.com/cctp/references/contract-addresses)
</Accordion>

<Accordion title="How do you get USDC on Injective Testnet?">
  On Injective Testnet, you can obtain Testnet USDC from the [Circle Faucet](https://faucet.circle.com/).
  You will likely also need to use the [Injective Testnet Faucet](https://testnet.faucet.injective.network/) to obtain Testnet INJ,
  in order to pay for transactions.
  You may also use [Circle's CCTP](https://www.circle.com/cross-chain-transfer-protocol)
  to transfer USDC from other supported networks.
</Accordion>

<Accordion title="How do you get USDC on Injective Mainnet?">
  On Injective Mainnet, you can transfer USDC to Injective from other supported networks using
  [Circle's CCTP](https://www.circle.com/cross-chain-transfer-protocol).
  The CCTP V2 contracts listed above handle the minting and burning of USDC for cross-chain transfers.
</Accordion>

<Accordion title="What is CCTP on Injective?">
  The Cross-Chain Transfer Protocol (CCTP) is Circle's native cross-chain infrastructure that enables
  USDC to be transferred between blockchain networks.
  On Injective, CCTP V2 contracts (`TokenMessengerV2`, `MessageTransmitterV2`, `TokenMinterV2`, and `MessageV2`)
  handle the minting and burning of USDC for cross-chain transfers.
</Accordion>

<Accordion title="What is the `restricted action` error when transferring USDC?">
  For regulatory compliance, every USDC transfer on Injective is validated by an EVM hook that calls a contract during the transaction.
  If your transaction runs out of gas mid-call, it will surface an error similar to:

  ```text theme={null}
  transfer is restricted by EVM hook: panic during EVM hook: types.ErrorOutOfGas: {EVM hook call failed}: contract hook query error: restricted action
  ```

  If the error includes `types.ErrorOutOfGas`,
  it does not mean the transfer was actually restricted.
  It means the validation call *ran out of gas* before completing.

  **Solution**: Retry the transaction with a higher gas limit.
</Accordion>

<Accordion title="Can USDC be used across both EVM and Cosmos on Injective?">
  Yes.
  USDC on Injective follows the [MultiVM Token Standard (MTS)](/developers-evm/multivm-token-standard),
  which means the same token balance is accessible from both EVM smart contracts and Cosmos-based modules.
  There is no need to bridge or wrap USDC when moving between the two execution environments.
