neos wallet

  • Double-entry ledger

    Every movement goes through one choke point that guarantees balanced debits and credits, with a running balance on each entry.

  • Multi-currency wallets

    One wallet per customer per currency, with transfers by wallet ID or e-mail — never across clients.

  • Mobile and web apps

    A mobile app (iOS/Android) and a web app with the same features and live balance updates.

  • Admin console

    Accounts, transactions, the ledger, audit log and system status; tenant management for the platform.

  • Partner API

    A public API for third-party integrations behind a rate-limited gateway, with a developer portal for self-service credentials.

  • KYC, cards and payments Roadmap

    Identity verification, card issuing and payment-provider integration.

How it works

  1. Every client, its own realm

    Identity is federated in Keycloak, one realm per client; the platform never sees a password.

  2. Every movement, a posting

    Transfers and top-ups create double-entry postings, validated per client.

  3. Every event, in real time

    The audit trail is published to Kafka and reaches the apps as events, without blocking operations.
