1. A method for using digital identity frameworks and infrastructure to access and interact with decentralized applications, comprising:
receiving, by a proxy smart contract, a trade from an authorized trader and an on-chain format of a verifiable credential, wherein the on-chain format of the verifiable credential comprises a flattened array of an authorized trader verifiable credential, a trusted entity verifiable credential, and root issuer verifiable credential;
verifying, by the proxy smart contract and using a verifier smart contract, the on-chain format of the verifiable credential, wherein the verifier smart contract queries a digital identifier registry to verify that an authorized trader digital identifier associated with the authorized trader verifiable credential, a trusted entity digital identifier associated with the trusted entity verifiable credential, and a root issuer digital identifier associated with the root issuer verifiable credential are active; and
in response to the authorized trader digital identifier, the trusted entity digital identifier, and root issuer digital identifier being active, executing, by the proxy smart contract and with a decentralized finance smart contract, the trade.
