Sei Network Warns USDC.n Could Become ‘Inaccessible’ After March
Why It Matters
The upgrade threatens the usability of USDC.n, risking loss for holders and highlighting the broader risk of bridge‑dependent stablecoins during chain migrations.
Sei Network Warns USDC.n Could Become ‘Inaccessible’ After March
Sei Network issued a warning to holders of USDC.n tokens, urging them to swap for native USDC
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,” the Sei team said 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).
