About

$WALL is a digital advertising protocol built on Solana where projects acquire permanent visibility slots on a fixed-size grid. Each slot, called a "brick," costs 1 USDC and remains owned indefinitely until sold through the protocol's marketplace. The platform uses x402 for all USDC transactions. This settlement infrastructure handles brick acquisitions, marketplace resales, and protocol fee collection without requiring multiple wallet signatures or token approvals. Ownership transfers occur exclusively through the on-chain marketplace. When a brick is resold, the protocol collects a fee from the transaction. The Wall includes social features allowing users to like and comment on bricks.
