Abstract: Methods and systems for multi-point token-based access control to online resources using a single wallet verification. A system, such as an e-commerce platform, receives a wallet address and digital signature from a user device during a user session, and obtains ownership data from a blockchain network with regard to the wallet address. Based on token ownership, the system determines whether the wallet address satisfies a token-based access condition. The system then detects a second access control event at a subsequent phase of the user session and, in response, obtains current ownership data from the blockchain network to determine whether a second token-based condition is satisfied before permitting a requested transaction in the subsequent phase.
