Crypto Registry: every USDT and ETH payment with its own document trail
This is what the books look like for a trading company that pays suppliers in USDT and contractors in ETH. The system only reads the chain and your documents: it moves nothing and holds no keys. Every payment gets a USD value on the date, a dossier the auditor can open, and a flag when a transfer needs a second look before the bank asks.

A pilot on one of your contracts
Two weeks. You provide the contract, invoices and wallet addresses; I build the registry, the dossier and the auditor statement on your data and walk your accountant through it. Then you decide whether you need the base version for every contract.
- transaction and wallet registry with import by address
- for groups and payment agents: several entities, agent-to-client reconciliation, client cabinets, statements per entity
- USD value on the date, ETH at market, realised gains and losses
- deal dossier: contract → invoice → tx hash → delivery note → customs or bill of lading
- review flag from $100,000 (your threshold) and a bank-ready dossier in one click
- auditor statement and export to QuickBooks, Xero or NetSuite
Pilot $1,500 · base from $6,000 · group registry for a payment agent or a group of companies $20–50k · paid in USDC or by invoice

What is not here
The system does not move money, hold keys, pick exchangers or file anything for you. It is bookkeeping: so that the accountant, the bank and the auditor share one answer to the question “what is this payment”.
