USDC token migration

We’re excited to announce that native USDC is now available on ZKsync and accessible to developers and users – no bridging required. Circle Mint and Circle APIs now fully support USDC on ZKsync.

Ensure native USDC is clearly named as "USDC" and the token symbol shows as "USDC" (Note: USDC has been rebranded from USD Coin, now the official name is simply "USDC")

Understanding native vs. bridged

Circle brings USDC natively to new blockchain networks to empower developers to build on a stable foundation they can trust. Native USDC is officially issued by Circle and is always redeemable 1:1 for US dollars.3

In the case of ZKsync, there also exists a "bridged" form of USDC known as USDC.e, which is USDC that has been bridged from Ethereum. Bridged USDC (USDC.e) is not issued by Circle.

Bridged USDC from Ethereum

• Token Symbol: USDC.e
• Mainnet Address: 0x3355df6D4c9C3035724Fd0e3914dE96A5a83aaf4

Native USDC issued by Circle

• Token Symbol: USDC
• Mainnet Address: 0x1d17CBcF0D6D143135aE902365D2E5e2A16538D4
• Testnet Address: 0xAe045DE5638162fa134807Cb558E15A3F5A7F853
