    Yellow

    Yellow is a clearing Network that uses state channels to facilitate trading and settlement through smart contracts and on-chain margin accounts. We are contributor of erc7824.org and looking for comments on our initiative. State Channels are a very powerful way to scale dApps in a chain agnostic way. Yellow leverage it to make trading fully non-custodial, cross-chain and infinitely scalable.
