Circle USDC.e to USDC Migration
Circle is launching native USDC on Starknet, replacing the bridged USDC.e as the standard stablecoin. This guide covers the migration process, timeline, and how avnu supports this transition.Quick Recap
For the upcoming USDC.e → native USDC migration:- Migration Support: avnu will integrate both the migration contract and liquidity pools. Our routing engine will automatically route users to the option offering the best rate at execution.
- Token List Update: On migration day, we will automatically update our token list. The current USDC address will be replaced by the new native one, and we’ll create a fresh USDC.e entry for the bridged token.
- Seamless Integration: All our integrators (wallets like Ready, Braavos, Xverse, Keplr, etc.) will receive these updates instantly.
Timeline
- Official Launch: December 3, 1 pm UTC (8 AM EDT).
- Circle public announcement of CCTP + native USDC
- 12 pm UTC: We merge the token list update (USDC.e and USDC token).
