Treehouse is a decentralized application that introduces Treehouse Assets (tAssets) and Decentralized Offered Rates (DOR), new primitives that enable fixed income products in digital assets. Users who deposit ETH or liquid staking tokens (LST) into the protocol receive tETH and contribute to the convergence of fragmented on-chain ETH rates. tETH also enhances the cryptoeconomic security of DOR, a consensus mechanism for benchmark rate setting.
