In a Sauce program, swap with @sauce/router’s function for the venue (uniswapV2, uniswapV3, uniswapV4, curve, balancerV2, …; Slipstream, PancakeSwap V3 and Algebra pools through uniswapV3), with a minimum output and, where the pool takes one, a price limit (the @sauce/router reference; several pools under one limit, the distributed swap).
DEX on Polygon with V2 (constant product, x*y=k) and V3 (Algebra-based concentrated liquidity with dynamic fees) pools.

​
What it offers

  • swapV2: Swap via V2 router with path routing
  • swapV3: Swap via V3 router with concentrated liquidity (Algebra, dynamic fees)
  • addLiquidity: Add liquidity to V2 pools
  • removeLiquidity: Remove liquidity from V2 pools

​
Notes

  • V3 uses Algebra protocol (same as Camelot V3): dynamic fees that adjust based on volatility, NOT fixed fee tiers
  • V3 uses limitSqrtPrice instead of sqrtPriceLimitX96
  • Polygon-only deployment
  • V2 uses standard Uniswap V2 interface with 0.3% fee
  • Prefer V3 for major pairs (better capital efficiency with dynamic fees)

Its names in a program

On Polygon, Quickswap is a namespace: its contracts need no import.

ABI

Where a line says what an address it returns is, a program that calls the function through its namespace calls that contract’s methods on the result directly: <Namespace>.<Contract>.<function>(...).<method>(...). A token’s methods are the ERC-20 functions, and its writes are SafeERC20.
