Cover letter

I've built a production double-entry ledger handling 4M+ daily entries with strict idempotency and reconciliation. For your escrow flow I'd model accounts for client funding, platform escrow, talent pending/available, and the fee account, then expose idempotent transaction APIs keyed on operation IDs. I'll include a reconciliation report and a full test suite covering refund and partial-release edge cases.
