Abstract

Methods and systems are described herein for performing a cold start operation of a system for acquiring non-fungible tokens (NFTs) using on-chain data. In particular, a user feed initialization system may receive an on-chain address associated with a cryptography-based storage application (e.g., an address associated with a crypto wallet of a user) and determine, based on the on-chain address, NFTs that the user's cryptography-based storage application controls (e.g., NFTs that the user owns). The user feed initialization system may use on-chain data associated with the NFTs (e.g., via interrogating the on-chain programs associated with the NFTs that the user owns) to identify (e.g., via a machine learning model) other NFTs that the user may desire to acquire.

Claims20

Dependent claims

A system for performing a cold start operation using on-chain data, the system comprising:

one or more processors;
and
one or more non-transitory computer-readable storage media storing instructions, which, when executed by the one or more processors, cause the one or more processors to:
in response to detecting an initial login associated with a user, for an on-chain user address associated with a cryptography-based storage application, retrieving blockchain operation datasets associated with the on-chain user address and extracting program identifiers for a plurality of on-chain programs from the blockchain operation datasets;
generating, using the program identifiers, data requests for the plurality of on-chain programs to obtain, from the plurality of on-chain programs, non-fungible token datasets associated with the on-chain user address, wherein each of the data requests comprises (i) a query to a corresponding on-chain program for non-fungible token data and (ii) a program identifier for the corresponding on-chain program, and wherein each of the non-fungible token datasets comprises a set of non-fungible token attributes associated with a corresponding non-fungible token;
inputting each set of non-fungible token attributes into a machine learning model to determine available non-fungible tokens for the user;
and
providing, via a data feed, indications of the available non-fungible tokens to a user device of the user.

5 more elements

A method for performing a cold start operation using on-chain data, the method comprising:

receiving an on-chain address associated with a cryptography-based storage application;
retrieving blockchain operation data associated with the on-chain address, wherein the blockchain operation data comprises one or more program identifiers for one or more on-chain programs;
generating, based on the one or more program identifiers, one or more data requests for the one or more on-chain programs to obtain one or more sets of non-fungible token attributes, wherein each data request of the one or more data requests comprises a query to a corresponding on-chain program for non-fungible token data, and wherein each set of the one or more sets of non-fungible token attributes is associated with a corresponding non-fungible token;
determining, via a machine learning model, one or more non-fungible tokens for a user based on the one or more sets of non-fungible token attributes;
and
providing one or more indications of the one or more non-fungible tokens to a user device of the user.

3 more elements

One or more non-transitory, computer-readable media comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

detecting a cryptography-based storage application associated with a user;
receiving an on-chain address associated with the cryptography-based storage application;
retrieving blockchain operation data associated with the on-chain address, wherein the blockchain operation data comprises one or more operations associated with one or more on-chain programs;
generating, based on the one or more operations, one or more data requests to obtain one or more program identifiers for the one or more on-chain programs, a respective one of the one or more program identifiers being associated with a corresponding set of non-fungible tokens;
determining, using data provided by a machine learning model, one or more non-fungible tokens for the user based on the one or more program identifiers;
and
providing one or more indications of the one or more non-fungible tokens to a user device of the user.
