Uniswap v2 Now Live Across More Major Chains

Uniswap v2 is now live on Arbitrum, Polygon, Optimism, Base, Binance Smart Chain, and Avalanche, and users can swap and provide liquidity on it directly through the Uniswap interface. The announcement says v2 is cheaper for swaps, averaging under a dollar on L2s like Optimism and Arbitrum compared with a $35 average on Ethereum. It also states that v2 pools cover the full price range by default, which reduces the need for active management by liquidity providers. The text adds that over $55 million was lost in v2 fork exploits, bugs, and rugs across Binance Smart Chain, Base, and Arbitrum in the past year, and presents official Uniswap v2 contracts as a more secure option.
