Flashside

Flashside is a set of NFT MEV contracts to claim Otherside land NFTs from various BAYC and MAYC 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/NFT20. 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

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.

Install Foundry using the installation steps in the README of the linked repo.

# 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 + LooksRare API.
