Ndax API integration services (Canadian crypto · CAD & staking OpenData)

Authorization & session bridge

We reverse engineer the Ndax mobile authorization flow — device binding, 2FA challenge handling and token refresh — and expose it as a clean REST facade. Typical use: allow a back-office tool to read a client's Ndax positions without scraping or screen share, while keeping session state isolated per tenant.

Trade history & statement export API

Pull executed orders, matched fills, CAD/crypto fees and cost basis per lot. Output is delivered as JSON, CSV or XLSX; fields are mapped to common accounting formats so the data lands directly into QuickBooks Online, Xero or Koinly pipelines used by Canadian accountants.

Real-time price & market data proxy

The Ndax mobile app exposes ticker widgets and market depth for its 60+ pairs. We wrap this in a normalized ticker endpoint and WebSocket stream so trading bots and BI dashboards can consume bid/ask, 24h volume and price change in a single schema across venues.

Staking rewards ledger

We surface per-asset staking events — delegation, accrual, payout, unstake and the 20% admin fee deduction — as an append-only ledger. The result powers CRA-ready income reports and lets finance teams reconcile staking yield across SUI, SOL, ETH, ADA, DOT, NEAR, ATOM and the recently added Sonic / SEI.

Interac & fiat rails webhook

CAD deposits and withdrawals — including the expanded $10,000 Interac e-Transfer cap introduced in 2025 — are pushed to your webhook within seconds. Use it to auto-create ledger entries, notify treasury, or trigger fraud checks on unusual CAD flows.

Portfolio snapshot & tax-lot engine

Combines balances, deposits, trades and staking into a point-in-time snapshot with ACB (adjusted cost base) — the Canadian tax methodology — computed per asset. Ready for CRA T1 reporting periods and for wealth platforms that roll Ndax into a broader household view.

1. Canadian crypto tax season automation

A tax software vendor onboards thousands of Canadians who trade on Ndax. By consuming the trade blotter + staking rewards + fiat ledger APIs, the tool computes ACB per asset, T5008-style disposition records and staking income. No more CSV uploads; the pipeline maps directly to Trade.execute_at, Trade.price_cad and Staking.payout_amount.

2. Treasury dashboard for Canadian SMBs

A small business holding BTC and ETH on Ndax feeds balances and CAD rails events into its ERP. The OpenFinance bridge normalizes Ndax alongside bank accounts so finance can see end-of-day cash plus crypto book value, and trigger alerts when an Interac deposit above $5,000 hits.

3. Portfolio aggregator for wealth platforms

A Canadian robo-advisor wants to show clients a single net-worth line combining Wealthsimple, Questrade and Ndax. The integration reads holdings, price_cad and staking_positions, pushing a consolidated snapshot to the app every 15 minutes through a read-only OAuth-style consent.

4. Crypto accounting & CRA reporting

Accounting firms ingest Ndax activity into Xero or QBO via a scheduled job. Each Ndax fill becomes a journal entry with CAD value, fees and realized gain/loss fields. Staking rewards flow to an income ledger; the 20% admin fee is posted as a deductible expense.

5. AML / fraud intelligence

A compliance team monitors deposit/withdrawal events against sanction and PEP lists. Webhooks deliver new Interac, wire and on-chain events; risky patterns — rapid fund-in, stake, withdraw — trigger a case in the AML tool, supporting Canadian FINTRAC expectations for CTPs.

Kraken

A global exchange active in Canada since 2011 with 400+ assets and a strong Kraken Pro API. Users who also trade on Ndax often need a unified trade blotter across both venues for CAD-denominated tax reporting.

Wealthsimple Crypto

Canadian robo-advisor with 3M+ users that places crypto next to stocks and ETFs. Aggregators often merge Ndax staking rewards with a Wealthsimple household view of registered and non-registered accounts.

Coinbase

Entered Canada in 2023 and holds CSA / FINTRAC / OSC registrations. Teams building a Canadian multi-exchange dashboard commonly pair Coinbase's public API with an Ndax data adapter for CAD completeness.

Netcoins

Vancouver-built exchange with staking up to ~15% APR and free Interac deposits. Similar CAD rail patterns make it a natural comparison when modelling Interac e-Transfer webhook semantics.

Shakepay

BTC-focused Canadian app with no explicit trading fees and a popular Shake Sats reward. Integrations often need to reconcile Shakepay's spread-based model against Ndax's transparent maker/taker figures.

VirgoCX

Toronto-based CTP with 60+ coins and free crypto withdrawals on most assets; sits in the same category as Ndax for CAD-first retail trading and reconciliation flows.

Bitbuy

Toronto exchange designed exclusively for Canadians. Integration buyers frequently request a shared schema so Bitbuy and Ndax statements can feed the same tax or accounting pipeline.

Coinsquare

Long-running Canadian venue with 60+ coins and fees rolled into the spread. A consolidated Coinsquare + Ndax export is common for traders rotating between platforms.

Crypto.com

Global platform operating in Canada since 2022 with 400+ assets and a card/rewards ecosystem. Users with an Ndax CAD account plus a Crypto.com Visa card often need unified spend and staking ledgers.

About our studio

We are an independent technical studio focused on App interface integration, authorized API integration and OpenData delivery. Our engineers come from banking, payments, crypto exchanges and protocol analysis backgrounds, and have shipped production connectors for Canadian, European and Asian fintech stacks.

For Canadian crypto platforms we know the CSA / CIRO restricted-dealer landscape, FINTRAC reporting rules and CIPF coverage mechanics. That context helps us translate app features — Ndax staking, Interac rails, CAD P&L — into API contracts that pass a Canadian compliance review rather than getting stuck at legal.

• Fintech, crypto, wealth & accounting integrations
• Custom SDKs in Python, Node.js, Go and Kotlin
• Protocol analysis → build → validation → compliance memo
• NDA / DPA signed on request
