Swap Kiwi (Niftyhorde)

Swap Kiwi (swap.kiwi) is an NFT trading platform developed by Niftyhorde GmbH, a Munich, Germany-based Web3 startup and Animoca Brands portfolio company, that enables peer-to-peer swaps of NFTs including ERC-721 and ERC-1155 tokens with no platform fees. Users initiate a swap by selecting NFTs from a connected wallet (MetaMask or WalletConnect) and proposing a trade to a counterparty's wallet address; the counterparty can add their own NFTs, and the initiator can accept or reject but not modify the proposal, ensuring a transparent process. Assets are held in a blockchain-based escrow smart contract for the duration of the swap, and either party can cancel at any point to recover their NFTs before completion.
