Deep Dive

1. Starknet Launch

Native USDC and CCTP on Starknet mean the stablecoin is issued directly on the chain and can move via Circles burn?and?mint infrastructure. This reduces reliance on third?party bridges and consolidates liquidity across ecosystems. The core launch was affirmed in the Starknet announcement and Circles post, which also highlighted day?one app support such as AVNU and Ekubo.

2. Migration From USDC.e

Starknets guidance explicitly recommends migrating from the bridged USDC.e to native USDC, prioritizing unified liquidity and a smoother user experience. The network provided steps in its migration thread, positioning native USDC as the canonical stablecoin on Starknet.

3. Connectivity Expands

CCTP and related tooling continue improving native?to?native mobility. For example, Wanchain announced a native?USDC bridge for Sei, enabling movement across many supported networks via CCTP V2 (Wanchain update). While this isnt a new chain adding USDC this week, it shows the broader trend of native USDC becoming easier to move between chains.

Conclusion

The chain that added native USDC this week is Starknet, with formal launch and migration guidance published by the ecosystem. The broader context is growing native coverage and easier movement via CCTP, which supports better liquidity and lower operational risk for stablecoin use across chains.
