Uniswap (V3) (Arbitrum)

What Is Uniswap (V3) (Arbitrum)？

Uniswap v3 is a novel AMM that gives liquidity providers more control over the price ranges in which their capital is used, with limited effect on liquidity fragmentation and gas inefficiency. This design does not depend on any shared assumption about the price behavior of the tokens. Uniswap v3 is based on the same constant product reserves curve as earlier versions, but offers several significant new features.

Uniswap v3 on the Arbitrum network - a Layer 2 scaling solution that enables near-instant transaction finality and low transaction fees while preserving the security guarantees of Layer 1 Ethereum.

What Are the Features of Uniswap (V3) (Arbitrum)？

• Concentrated Liquidity: Liquidity providers (LPs) are given the ability to concentrate their liquidity by "bounding" it within an arbitrary price range. This improves the pool's capital efficiency and allows LPs to approximate their preferred reserves curve, while still being efficiently aggregated with the rest of the pool.
• Flexible Fees: The swap fee is no longer locked at 0.30%. Rather, the fee tier for each pool (of which there can be multiple per asset pair) is set on initialization. The initially supported fee tiers are 0.05%, 0.30%, and 1%. UNI governance is able to add additional values to this set. 
• Protocol Fee Governance: UNI governance has more flexibility in setting the fraction of swap fees collected by the protocol
• Improved Price Oracle: Uniswap v3 provides a way for users to query recent price accumulator values, thus avoiding the need to checkpoint the accumulator value at the exact beginning and end of the period for which a TWAP is being measured. 
• Liquidity Oracle: The contracts expose a time-weighted average liquidity oracle
• Uniswap v3 introduces multiple pools for each pair of tokens, each with a different swap fee. All pools are created by the same factory contract. The factory contract initially allows pools to be created at three fee tiers: 0.05%, 0.30%, and 1%. Additional fee tiers can be enabled by UNI governance. 
• Arbitrum will support throughput of 80k arb gas per second, which should translate to transaction capacity roughly in line with Layer 1. Unlike L1, transactions on Arbitrum confirm instantly — no more pending or stuck swaps!
