Numary

Numary has presented 1 V-Sum technical briefing. Clément of Numary demos Numary\'s open-source ledger and Numscript — a DSL purpose-built to model the hidden money-flow complexity of marketplaces and platforms (where customer payments, commission splits, and seller payouts quickly become an operational mess). The demo clones a DoorDash-style marketplace in Numscript: a "world" account injects funds, a coupon account funds a $15k FALL21 marketing campaign with a $10-per-redemption metadata value, an order\'s payment account pulls first from the user\'s wallet and falls back to world, and a single atomic Numscript splits the order payment four ways — 85% to the restaurant, a delivery amount to the rider, platform fees, and VAT-applicable taxes. Each step produces a transaction with clean source/destination postings in the Numary ledger, which the fintech later reconciles against Stripe, Wise, or their payment provider of record. The closing rider payout demonstrates the reconciliation handoff between Numary\'s internal ledger and the external payment system — the Numscript repo is open-sourced on GitHub at github.com/numary.
