A sponsor (an account with a linked Solana wallet: one made by Sign in with Solana has its own) proposes a competition scored by a house template and funds its placement prizes from that wallet; the deposit sits in the on-chain escrow from the moment it is signed until the house approves it (the escrow opens and the competition is listed) or returns it (rejected with a reason and a fix for each check it failed, withdrawn by the sponsor, or expired past the review deadline, when anyone may return it). This is what a sponsor accepts before a deposit: the sponsor terms in force (their version, which proposal_deposit's terms_version names to accept them; their status, a draft until counsel signs off; every clause), the sha256 of their canonical JSON (keep it to prove the text you accepted), this server's limits (the prize pool's floor and ceiling in USD, min_prize_usd and max_prize_usd, null for no bound on that side: no floor is any amount above $0 in whole cents; a Cheapest to build bounty's build allowance floor and ceiling in USD, min_allowance_usd and max_allowance_usd, null for no bound on that side, and how much of it each entrant's build keys spend by default, build_key_per_entrant_usd; the review hours after which make.fun opens entries at the soonest, min_entries_hours, the shortest time entries stay open (15 minutes on the house's schedule, any length past it, as competition.duration_hours names it), proposals in review at once and submitted per day, the escrow's mint and cluster) and whether the desk takes deposits now (intake_open). Anyone may read them.
