$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. Brick owners can boost their visibility by paying with $WALL tokens, increasing exposure on the grid. The $WALL token has two utilities: boost payments and deflationary pressure through protocol-funded buybacks. 30% of all brick sales revenue is allocated to purchasing $WALL tokens on the open market and permanently burning them, reducing circulating supply over time. Boost payments provide additional demand for the token beyond the buyback mechanism. Total supply is 1 billion tokens. The token launched in December 2024 via pump.fun with 80% public distribution and 20% allocated to the team with a two-month lock period.
