USDC on Arbitrum One

Arbitrum One supports two different types of USDC:

1. USDC: USDC tokens that are native to the Arbitrum One chain.
2. Bridged USDC (USDC.e): Ethereum-native USDC tokens that have been bridged to Arbitrum One.

Differences between USDC and USDC.e

	USDC	Bridged USDC
Token Name	USDC	Bridged USDC
Token Symbol	USDC	USDC.e
Token Address	0xaf88d065e77c8cC2239327C5EDb3A432268e5831	0xff970a61a04b1ca14834a43f5de4533ebddb5cc8
Benefits	CEX Support, directly redeemable 1:1 for U.S. dollars

The Arbitrum Bridge will continue to facilitate transfers of all USDC tokens. When depositing Ethereum-native USDC, the option exists to receive Bridged USDC using Arbitrum's bridge or Arbitrum-native USDC using Circle's Cross-Chain Transfer Protocol.

Historical context

The Arbitrum Bridge will continue to facilitate transfers of all USDC tokens. When depositing USDC from Ethereum, the option exists to receive USDC using Circle's Cross-Chain Transfer Protocol or receive Bridged USDC using Arbitrum's lock-and-mint bridge. In 2023, Circle launched USDC natively on Arbitrum One and added support for the Cross-Chain Transfer Protocol, which enabled direct minting and burning of USDC between Ethereum and Arbitrum One. Due to this, the token symbol for Bridged USDC has been renamed to USDC.e to accommodate an ecosystem-wide liquidity migration to native USDC. The expectation is that over time, the liquidity migration of USDC.e to USDC will continue.
