Why Vaultly

Money safety, developer joy.

Every primitive you need to ship a multi-currency product — without reinventing accounting, FX, or auth.

Vault-grade ledger

Atomic, double-entry transfers with row-level locking and idempotency keys. Every cent has a paired credit and debit.

150+ currencies, one balance

USD-based ledger with live conversion to fiat & crypto. Auto-refresh from exchangerate-api and Wallex (IRR).

7-step preamble auth

Cryptographically chained per-request preamble keeps replay attacks out, even if a key leaks.

Programmable withdrawals

Submit, approve, and reconcile with admin workflows and webhook-friendly state transitions.

Real-time everything

Sub-millisecond balance reads, live FX rates, and instant transfers. Cron-driven refresh for exchange data.

Audit-ready by default

Every transfer, withdrawal and adjustment is immutable, timestamped, and queryable through the admin panel.

3 simple steps

From zero to first transfer in minutes.

01

Sign up

Create your account, verify your email, and land on a clean dashboard.

02

Generate API keys

Each key is a wallet — name it, secure it, and keep using it.

03

Move money

Send transfers, request withdrawals, query balances. All from one API.

Developer-first API

REST that reads like English.

No SDK lock-in. Authenticate with a 7-step preamble header, send JSON, and you're done. Every response is predictable: { "ok": true, ... }

✓ POST /api/v1/transfer
✓ POST /api/v1/withdraw
✓ GET /api/v1/balance
