Double-entry ledger
A transaction is a set of postings with a source and a destination, and it is rejected unless it balances. Entries are immutable — a correction is another transaction, so history stays true.
Hanzo Treasury
A double-entry ledger for money moving inside your product
// A $100 order, split three ways, written once.
// Numscript refuses to run this if the amounts do not add up.

Wallets with holds
Multi-currency virtual wallets that can hold an amount and release it later. That is how you take money at checkout and pay a seller on delivery without the balance lying in between.

What it is made of
A ledger, a language for writing transactions, and the machinery around them.
Reconciliation
Match what the ledger believes against what a payment provider reports, and show the rows that disagree. The breaks are the output; agreeing totals need no attention.
Accounts and balances
Hold balances per account and per currency, and move between them as ledger transactions. What an account settles against is configured per deployment.
Flows and webhooks
Longer sequences — capture, split, pay out, retry — run as orchestrated flows, and every change of financial state is delivered as an event you can subscribe to.
