Uniswap V4 Docs
Protocol Documentation
Improved protocol documentation and authored delta handling guidance for liquidity modifications.
01 · Requirement Analysis
V4's flash-accounting and unlock-callback model confused integrators — especially how to settle currency deltas after liquidity modifications. The task was to make that flow legible and correct in the official docs.
02 · Architecture Discovery
Read the V4 PoolManager, the unlock callback, and how currency deltas accumulate then settle within a single transaction. Traced real callback paths so each explanation was grounded in actual control flow.
03 · Software Architecture
Documentation structured as guide → concept → reference, with the unlock-callback and delta-handling pages authored as the canonical path integrators follow when modifying liquidity.
04 · Development Principles
Accuracy over the lifecycle ordering, minimal working snippets, single-source-of-truth explanations, and explicit callouts for the invariant — deltas must net to zero before settlement.
05 · Impact
Reduced integration confusion for V4 hook and router authors, establishing a reference path that later contributors extend.
