UniswapV3Juggler
GitHub: link
Given xPYT/NYT input, computes how much to swap to result in an equal amount of PYT & NYT.
Used in conjunction with UniswapV3Swapper::swapNytToUnderlying() and UniswapV3Swapper::swapXpytToUnderlying(). Should only be called offchain since the gas cost is too high to be called onchain.
Constants
MIN_SQRT_RATIO_PLUS_ONE
uint160 MIN_SQRT_RATIO_PLUS_ONE
The minimum value that can be returned from #getSqrtRatioAtTick + 1. Equivalent to getSqrtRatioAtTick(MIN_TICK) + 1 Copied from v3-core/libraries/TickMath.sol
MAX_SQRT_RATIO_MINUS_ONE
uint160 MAX_SQRT_RATIO_MINUS_ONE
The maximum value that can be returned from #getSqrtRatioAtTick - 1. Equivalent to getSqrtRatioAtTick(MAX_TICK) - 1 Copied from v3-core/libraries/TickMath.sol
MAX_BINARY_SEARCH_ITERATIONS
uint256 MAX_BINARY_SEARCH_ITERATIONS
The maximum number of binary search iterations to find swapAmountIn
Immutable parameters
factory
address factory

juggleXpytInput
function juggleXpytInput(contract ERC20 nyt, contract ERC4626 xPYT, uint24 fee, uint256 tokenAmountIn, uint256 maxError) external returns (uint256 swapAmountIn)
Given xPYT input, compute how much xPYT to swap into NYT to result in an equal amount of PYT & NYT.
| Name | Type | Description |
|---|---|---|
| nyt | contract ERC20 | The NYT contract |
| xPYT | contract ERC4626 | The xPYT contract |
| fee | uint24 | The fee tier of the Uniswap V3 pool to use |
| tokenAmountIn | uint256 | The amount of token input |
