Which L2s have native USDC now?

TLDR

Today, the Ethereum L2s with native USDC are Arbitrum and Base. This is enabled through Circles CCTP, which supports native USDC across multiple networks including Arbitrum and Base per a recent market piece on stablecoin rails. See the confirmation in a news recap that USDC now operates natively via CCTP on networks including Arbitrum and Base in the past week market update.

1. Arbitrum and Base both support native USDC flows, with payments tooling actively using USDC on these L2s merchant integration note.
2. Native USDC reduces bridge risk and enables mint/burn transfers across supported chains via CCTP market update.

Deep Dive

1. Arbitrum

Arbitrum supports native USDC via Circles Cross?Chain Transfer Protocol (CCTP), which burns on the source chain and mints native USDC on the destination chain, avoiding wrapped tokens. A recent market update explicitly lists Arbitrum among networks where USDC functions natively via CCTP market update.

Payments infrastructure also cites USDC support on Arbitrum in live merchant flows, reinforcing production readiness for stablecoin payments on this L2 merchant integration note.

2. Base

Base likewise supports native USDC via CCTP. The same market recap includes Base among the networks where USDC now operates natively through Circles protocol market update.

Merchant infrastructure has also highlighted USDC support on Base in production payment rails, indicating growing real?world usage for stablecoin settlement on this L2 merchant integration note.

Conclusion

Based on sources from the past week, the Ethereum L2s with native USDC are Arbitrum and Base. Native issuance via CCTP helps reduce bridge risk and improves settlement quality for payments and DeFi. If you want, I can watch for additional L2s as Circle expands support and update this list.
