TLDR
USDC is live on several Ethereum L2s now, including Arbitrum (ARB), Base, and Linea, per recent announcements and integrations.
- Arbitrum supports USDC for merchant payments per a recent integration report.
- Base has active USDC support, cited in the same integration report and a press release.
- Linea is specifically noted for USDC transactions in a recent press release.
Deep Dive
1. Arbitrum
USDC is supported on Arbitrum (ARB) for payments and merchant processing, as highlighted in a gateway integration that adds ETH and USDC on Arbitrum and Base for lower-fee transactions and faster confirmations on L2s. See the integration report.
If you prioritize speed and cost, Arbitrums L2 environment can make USDC transfers cheaper and near-instant compared with Ethereum L1.
2. Base
USDC is actively used on Base for payments and card programs. One merchant integration explicitly supports USDC on Base, and a card providers U.S. launch mentions USDC transactions on Base. See the integration report and a related press release.
Base offers USDC transfers with low fees and fast settlement, useful for consumer payments and merchant acceptance within the Coinbase-affiliated L2 ecosystem.
3. Linea
USDC transactions on Linea are called out in a recent U.S. debit card launch, which lists Linea among supported networks. This indicates operational USDC usage for card spending flows on the L2. See the press release.
Linea is another L2 option where USDC can move with low friction, potentially appealing for dApp payments and cross-ecosystem spending.
Conclusion
Recent integrations and announcements show USDC active on Arbitrum, Base, and Linea, aligning with L2 goals of lower fees and faster settlement for payments and transfers.
