Sei Network issued a warning to holders of USDC.n tokens, urging them to swap for native USDC ahead of a major upgrade planned for March.
USDC.n is a bridged version of Circle’s USDC stablecoin on the Sei Network, originally issued on the Noble appchain and enables interoperability in ecosystems like Cosmos.

The SIP-3 upgrade, scheduled for the mainnet in March, will transition Sei to an EVM-only chain, meaning it will no longer support Cosmos-native assets like USDC.n.
“After this upgrade, USDC.n may become inaccessible or lose its value on the Sei Network,” said the Sei team in a statement
The team urged holders to use tools like DragonSwap or Symphony to swap small amounts, and Brr to migrate larger volumes through Circle’s Cross-Chain Transfer Protocol (CCTP).
