Taker is a liquidity protocol for novel crypto assets. It uses a quote-by-lock-in approach to price and allows asset holders to borrow stable coins. Taker starts with NFT assets to provide lending services for all kinds of novel crypto assets of the future. (1) The Taker protocol designs a new model for NFT lending. Soon, NFT synthetic indexes will be introduced to DeFi NFT assets and stimulate the liquidity and turnovers of NFT’s. (2) The Taker protocol builds cross-chain bridges to connect various public chains, such as ETHEREUM, POLKADOT, NEAR, SOLANA, and Polygon. These bridges will enhance the efficiency of asset transfer and enrich application scenarios. (3) The Taker token ensures effective collaboration for holders to use their voting power and participate in community governance. (4) The Layer 2 network is constructed using Polygon to reduce gas cost, improve asset turnovers, and expand data processing capacity. The network’s DeFi attributes and NFT ecology are supported by our protocol.
