USDC fragmentation risk #112

Open detectivekim opened 11 months ago

detectivekim commented 11 months ago

Details

There is both bridged USDC (USDC.e) and native USDC that Circle introduced on Arbitrum. This complicates matters because it is likely for both to use the same price feed, but the bridged USDC could possibly de-peg from the native one due to bridge hacks, or other black swan events. In addition, they share the same token symbol, so while they have separate addresses, the ERC20 wrapped coupon symbol and name would be the same too.

Mitigation

Something to bear in mind and consider as an edge case scenario to deal with.

Yeap, we should consider this issue again before the live production.
