Horizen to Shut Down Cross-Chain Bridge on November 4; USDC.e Not Included in Refund Plan

Horizen will shut down its L3-to-Base cross-chain bridge on November 4 at 21:00 Beijing time, with users required to move assets before the deadline. Notably, USDC.e operated via Stargate is excluded from the Horizen DAO's refund plan, so holders must bridge it out themselves before the cutoff. At closure, Horizen will snapshot all balances and staking positions, and after a one-week public review, the DAO plans to return remaining ZEN—including unclaimed staking rewards—and any balances above 0.001 ETH to the same addresses on Base, expected in the second half of November. The shutdown was accelerated by Base's Denim upgrade, which will leave the Horizen L3 unable to process user transactions. Key items to watch: whether USDC.e holders exit in time, the snapshot and review process, and the timing of the DAO's refund distribution on Base.
