# Flashside
Flashside is a set of NFT MEV contracts to claim [Otherside land NFTs](https://twitter.com/yugalabs/status/1505014986556551172) from various [BAYC](https://opensea.io/collection/boredapeyachtclub) and [MAYC](https://opensea.io/collection/mutant-ape-yacht-club) pools, via flashloans or flashswaps.
Assuming land has a floor of at least 2.5 ETH (the pre-sale whitelist cost) and hypothetically 5+ ETH, only profitable opportunities are mocked. For this reason, strategies like flashloaning xBAYC from NFTX are ignored (because of their relatively high average cost of 20 ETH/land).
## Potential strategies
1. Flashloans from NFT pools like [NFTX](https://nftx.org/)/[NFT20](https://nft20.io/). Only profitable for some pairs due to high index token costs (for example, NFTX costs `0.14x` token: `0.04` on claim, `0.1` on deposit)
2. Atomic purchase, claim, and sale into collection floors via [LooksRare](https://looksrare.org/)
## Implemented Strategies
1. `FlashsideNFT20` — 0-cost flashloan and claim via BAYC from NFT20
2. `FlashsideLooksRare` — ~1-1.5 ETH/land atomic purchase, claim, and sale via MAYC from LooksRare
## Test
Tests use [Foundry: Forge](https://github.com/gakonst/foundry).
Install Foundry using the installation steps in the README of the linked repo.
```bash
# Get dependencies
forge update
# Run tests against mainnet fork
forge test --fork-url=YOUR_MAINNET_RPC_URL
```
**Note:** Tests for `FlashsideLooksRare` currently require manual entry of test orders in `test/FlashsideLooksRare.t.sol`. In the future, this should be ingested via [Forge FFI](https://github.com/foundry-rs/foundry/blob/3f13a986e69c18ea19ce634fea00f4df6b3666b0/testdata/cheats/Ffi.t.sol) + [LooksRare API](https://looksrare.github.io/api-docs/#/Orders/OrderController.getOrders).
