1 min read
Pronunciation
[wuhn-click el-pee zap]
Analogy
Like a one‑click checkout on e‑commerce that fills your address, payment, and shipping details automatically.
Definition
A user flow that abstracts multiple steps of providing liquidity—token approvals, pairing, staking—into a single action (“zap”), simplifying LP onboarding.
Key Points Intro
One‑click LP zaps streamline liquidity provisioning with a single transaction.
Key Points
Batching: Combines swaps, approvals, and `addLiquidity()` calls.
Slippage control: Applies safeguards across all sub‑transactions.
Token routing: Automatically sources required token pairs.
UX simplification: Single confirmation dialog.
Example
A DEX front end lets users click “Provide Liquidity” once; the zap contract swaps half their ETH for DAI, approves both, and supplies the ETH‑DAI pool.
Technical Deep Dive
Zap contract uses `multicall`: first `swapExactETHForTokens()`, then `approve()`, then `addLiquidity()`. It reverts atomically on any failure and emits detailed events.
Security Warning
Complex zaps can have hidden slippage or front‑running risk; review contract code.
Caveat
Single‑click hides complexity; advanced users may lose fine‑grained control.
