UseNosh implements a novel, on-chain mechanism for directing memecoin creator fees toward NFT floor sweeps on Robinhood Chain. Its core contracts — the fee router, vault, and raffle distributor — are described in detail across the website and docs (web_1, web_2), with explicit, immutable rules: 80/20 fee split hardcoded in EIP-1167-cloned routers; vaults lack withdraw functions and enforce Seaport-only, cap-bound sweeps; raffles use drand-backed OpenVRF with public challenge windows and permissionless draw resolution. Privileged actions are narrowly scoped: the keeper posts floor caps (1h TTL), snapshots holders, and opens raffles — but cannot withdraw ETH, re-roll draws, or override custody logic. External vaults introduce off-chain coordination but retain on-chain accountability via time-locked withdrawals and Zcash viewing keys (web_2). No audit reports, formal threat model, or third-party verification of contract behavior is present in the evidence. The primary thesis — that fees reliably convert to NFTs and distribute them fairly — rests entirely on claimed design, not verified execution or adversarial testing. Market data (api_2) shows circulating supply near max, but no liquidity, volume, or holder distribution metrics are supplied. While architecture is transparent and privilege surfaces are well-documented, absence of independent security validation limits confidence in runtime correctness.
