Recently, Circle announced the launch of USDC on Avalanche, which is the native USDC token on the Avalanche blockchain (specifically, Avalanche C-Chain).
 

Circle customers are able to mint native USDC on Avalanche from the Circle Mint account and Circle APIs. Similar to other native USDC tokens on other blockchains, you can deposit USDC on Avalanche back into a Circle Mint account and off-ramp to fiat currency seamlessly.
 

USDC.e on Avalanche is a "bridged form of Ethereum USDC" that was bridged from the Ethereum blockchain via the Avalanche Bridge. For this reason, USDC.e is not the same as native USDC. Circle products do not support USDC.e.
 

You cannot send USDC.e to a Circle deposit address.
 

To elaborate, it is not possible to use USDC.e in the Circle APIs, nor deposit USDC.e into a Circle Mint account and off-ramp back to fiat currency.
 

To off-ramp back to fiat currency with USDC.e, you would need to "unbridge" the USDC.e back to the Ethereum blockchain via the Avalanche Bridge. After the "unbridging", you would end up with native USDC on Ethereum ("Ethereum USDC"). At that point, you would be able to deposit the Ethereum USDC into your Circle Mint account and off-ramp to fiat currency. You could also deposit the Ethereum USDC into your Circle Mint account and withdraw the corresponding amount of USDC on Avalanche to an Avalanche external address.
