YieldApp has opened its testnet to the public, allowing wider community access to its verifiable yield marketplace. The platform is the first of its kind to be powered by live, cryptographic proofs of yield data, provided by Accountable's Data Verification Network. This move follows a period of stress-testing by a group of early users. The testnet allows users to explore and interact with the marketplace's features. The company's goal is to build a premium marketplace for verifiable yield, aiming to increase transparency and trust in the DeFi space.
