Abstract: Systems and methods for upgradable smart contract factories are disclosed. A system can provide, on a blockchain of a blockchain network, a beacon contract configured to (i) deploy proxy contracts in response to corresponding requests and (ii) maintain a list of a plurality of implementation contracts stored on the blockchain. Each implementation contract can corresponding to a respective token type. The system can invoke the beacon contract to deploy a first proxy contract corresponding to processing of a first token type, contract causing the blockchain network to determine that the list includes an implementation contract corresponding to the first token type, generate the first proxy contract on the blockchain, and provide an address of the first proxy contract in response to the request.

Abstract: Systems and methods for token metadata management are disclosed. A system can determine that a token has been minted on a blockchain based on a smart contract identifying an identifier of the token and a base uniform resource identifier (URI). Responsive to determining that the token has been minted on the blockchain, the system stores metadata for the token at a location in a database. The database corresponds to the base URI and the location in the database is identified by the identifier of the token. The system generates a metadata URI for the token based on the base URI and the identifier for the token, detects a change to a status of a contest identified in the metadata of the token, and upon detecting the change to the status of the contest, modifies the metadata of the token using the metadata URI.
