Hostra for enterprises
Enterprise payment teams rarely start from zero. They already have an ERP, a treasury process, existing providers and a finance function that has to explain every number. Hostra is designed to sit alongside those systems as the settlement and ledger layer, not to replace them.
Where Hostra fits
Hostra owns the part between "we decided to move money" and "the movement is final and accounted for": durable intents, execution against the chosen rail, terminal state, and balanced double-entry postings. Your systems of record keep owning approval, procurement, treasury policy and reporting; they consume Hostra's events and read its ledger rather than re-implementing settlement logic internally.
Controls
- Scoped access: machine-to-machine keys with RBAC scopes, so a reporting integration cannot initiate a payout.
- Idempotency: every mutation takes a UUID v4 Idempotency-Key, making retries safe across your own middleware and queues.
- Reversal as a first-class operation with its own scope and its own ledger entries, instead of manual corrections.
- Tamper-evident audit hash-chain with a verification endpoint — useful when an internal or external reviewer asks whether history could have been edited.
- Structured errors (RFC 7807) and X-Request-ID correlation for incident response.
Processing at scale
The engine is built around failure rather than throughput theatre: intents survive process death, exclusive leases with fencing tokens stop two workers executing the same instruction, and query-before-retry reconciles with the provider before any repeat call. The result is that scale-related incidents — timeouts, restarts, partial outages — degrade into delays rather than into duplicate or missing money movements.
Rails and reconciliation
Card charge, card push (Visa Direct OCT) and on-chain stablecoin disbursement are available today; ACH, SEPA, SWIFT and wire are on the roadmap and not available. Whichever rail executes, reconciliation works the same way: derived balances, immutable entries, and a provider or network reference attached to the settlement record. See the ledger for the accounting model.
Position
Hostra is not a bank, a regulated financial institution or a licensed money transmitter, and it holds no regulatory authorisation. Enterprises integrate Hostra as technology within their own regulatory and banking arrangements.
