Rigor is an innovative decentralized finance (DeFi) protocol for construction lending and payments. It enables lenders to find and finance building projects, gain transparency into the flow of their digital dollars, and be governed by smart contracts, all secured on a blockchain. As construction tasks are completed and verified, Rigor automates payments for them, paying the small businesses responsible for the work immediately and directly. When the home is sold, the lender is repaid with a fixed-yield rate, plus interest.
