Smart Contract Details

An in-depth description of the Ammplify smart contract.

High-Level Description

Ammplify is a protocol that wraps UniswapV3, manages deposits by breaking them into smaller pieces.

This means when a users deposits a typical UniV3 range, we split it into smaller pieces and re-deposits them back into UniV3. The reason to do this is because each piece falls into a bucket and all liquidity within each bucket is fungible. This allows us to apply two optimizations on each bucket: auto-compounding and borrowing.

In contract, the buckets are nodes in our segment tree and borrowed liquidity is called Taker liquidity. Regular liquidity is called Maker liquidity and Maker liquidity is split into a compounding version and a non-compounding version.

High-level Architecture

Ammplify is built according to the Diamond standard (EIP 2535) and it installs these facets:

• Maker Facet (For opening and closing liquidity positions)

• Taker Facet (A privileged facet for borrowing liquidity)

• View Facet (For examining contract storage)

• Admin Facet (For managing Taker rights and time-gating and protocol changes)

• Pool Facet (For interacting with the underlying pool)

The meat of the complexity is in the Walker library called by the Maker and Taker facets to deposit/borrow liquidity to/from the nodes in the segment tree stored in the tree folder. The majority of the tree logic is in Route.sol.
