Horizen set a November 4, 13:00 UTC bridge cutoff as it winds down its layer-three network. The source does not give a year for the cutoff. Holders must check the instructions for their specific assets; submitting a bridge transaction does not mean the transfer has finished.
Horizen says a later DAO return will cover ZEN and qualifying ETH balances, but not USDC.e. Smart-contract wallets need special handling, and an ETH minimum balance threshold applies. The project attributes the accelerated transition to compatibility issues tied to Base’s Denim upgrade and plans to make Base its ecosystem’s primary chain.
