Problem Statement

Instant liquidity from your ETH using virtual debit cards. No KYC required. Immediately get the card details and use it for IRL purchases. In future, integrations with 0x swap would ensure that all tokens can be accepted. Additionally, Polygon ID solution would protect against sybil attacks.

Solution

Leveraging Lithic's API to issue virtual debit cards. Authorization server is self-hosted so that allows ability to APPROVE/DECLINE transactions. Using transaction hash to fetch the amount and converting that USD amount to set the spending limit for the virtual debit. The virtual debit card is issued against my personal account.
