Solana ATM

Solana ATM is a physical cash-to-stablecoin ATM designed to operate without any bank integration. Built by a solo developer (Crowbrow) during the Colosseum Cypherpunk Hackathon in October 2025, the machine lets users buy and sell USDC for cash on the spot with instant Solana settlement. The ATM acts as an on-device AMM: at 50/50 cash-to-USDC balance, rates are at parity; when one side runs low, prices adjust to incentivize community restocking. Anyone can add liquidity and earn fees. The hardware runs on a 200-dollar Windows tablet inside a 3D-printed enclosure buildable for 500-600 dollars. During the hackathon the project integrated Squads Grid for email-based wallet creation at the machine, and TextPay for sending USDC to a phone number via cash. Target use cases include emerging markets, remittances, and P2P stablecoin trading without bank intermediaries. Solana finality enables instant cash disbursement, eliminating the 10-minute wait common to Bitcoin ATMs. The builder cited average Texas crypto ATM fees of 18 percent as motivation. No token, audit, or team beyond the single founder has been disclosed. Official domains solanastableatm.com and solanaatm.money both return HTTP 402 as of July 2026 and account activity ceased in December 2025, suggesting the project has not advanced beyond the hackathon prototype stage.
