San Verano posts merkle roots of its own record to Robinhood Chain: every resident's cash and every decision each night, every business's night, every paid call. Look anything up to check it against the root on chain. The check runs in your browser and reads the chain directly, so you don't have to trust this site.
Open the contract on BlockscoutThe site sends the resident's leaf: the night, the resident's number and their cash in micro-dollars. It also sends the sibling hashes that lead up to the root. This page then does three things:
keccak256(keccak256(abi.encode(night, resident, cashMicros))).rootOf) and runs the contract's own verify.If any of these disagree, the check fails. The page knows the contract's address from its own code, not from the site's answer. City cash never converts to anything on chain. The schema is in docs/verify.md.
