Solcala

What it is

Split client and server: a React client that only renders, and an Express and Socket.IO server that owns every rule, so a modified client cannot manufacture a result it would be paid for. Underneath is a custodial ledger that will not credit a deposit on a client’s say-so — the transaction is fetched by signature, rejected if it failed, checked that the depositing wallet actually signed it, and matched on exact atomic amount into the treasury token account, with a balance-delta fallback when instruction parsing does not resolve. Settlement pays out with a platform fee off the pot, creates the recipient account on demand and confirms before the ledger closes, with a refund path for matches that do not resolve. BigInt atomic units throughout, never floats.

Who built it
