Uniswap Moves Unichain to OP Enterprise on October 13: What It Means for Your Coins on the Chain

Unichain, the layer-2 chain run by Uniswap, is changing its technical foundation. The testnet migrates on October 13, 2026, with the mainnet following on October 29. For your balance on the chain, Uniswap says this means nothing at all. Chain ID, contracts, balances and applications stay the same, and Uniswap v2, v3 and v4 keep running as before. What changes is the operation behind the scenes, and that is the part that concerns you as a holder.Uniswap announced the move on its own blog on October 9, 2026.
