DeFi Pulse is a service that ranks Decentralized Finance applications by how much money, i.e. Ether, Bitcoin or Dai) is locked in their smart contracts. Tokens may be locked for a variety of reasons such as loan collateralization as in MakerDAO or to provide automated liquidity as in Bancor and UniSwap. Also included are second-layer networks like Bitcoin's Lightning Network or the XDai sidechain which lock value on the main chain to issue their own equivalent tokens.
