AFGCoinExchange API integration (BEP-20 / OpenFinance)

1. Crypto accounting and tax export

An accounting SaaS pulls the AFGCoin staking ledger and AFG↔USDT conversion log nightly, normalises each entry into ledger-standard rows (date, base asset, quote asset, fee, USD value at execution time) and pushes them into QuickBooks, Xero or a custom data warehouse. Daily accruals at roughly 0.6% are tagged as income on the date of credit, while swap legs are paired into cost-basis events. This is a pure OpenFinance scenario: the data already exists in the app, the integration just makes it queryable.

2. Treasury and NAV dashboard

A small fund or DAO needs a single dashboard combining AFG holdings on AFGCoinExchange with positions held on Binance, Bybit, KuCoin and self-custody wallets. The integration polls the AFG balance and staking sub-balance every minute, signs each value with a venue identifier, and feeds them into a Grafana board next to live AFG market quotes. Treasury staff see realised yield, unrealised P&L and venue concentration in one place.

3. Compliance & AML monitoring

A regulated payment service provider adds AFGCoin transfer monitoring to its existing AML stack. The integration streams deposit and withdrawal events with their BscScan hashes into a rules engine that screens counterparties against sanctioned-address lists, applies the FATF Travel Rule for transfers above the relevant threshold and produces SAR-ready evidence packs. Login and KYC state are joined in for customer risk scoring.

4. White-label crypto onboarding flow

A neobank that already supports SEPA, UPI and card rails wants to offer AFGCoin staking inside its own app. The integration mirrors the AFGCoinExchange login, balance and stake-claim endpoints, but presents them inside the neobank shell. Users keep one login, one statement and one tax export, while the underlying staking continues to settle on AFGCoinExchange.

5. Research / market-data ingestion

An analytics startup combines aggregated, anonymised conversion volumes from AFGCoinExchange with on-chain data from BNB Smart Chain and price feeds from CoinGecko. Outputs feed a research dashboard tracking AFG liquidity, yield decay and average swap size — the kind of dataset typically only available through a paid market-data provider.

Compliance & privacy

Crypto integrations carry stricter obligations than ordinary OpenBanking flows. Every AFGCoinExchange engagement we deliver is scoped against the FATF Travel Rule for virtual-asset transfers and the European Union Markets in Crypto-Assets (MiCA) regulation, which became fully applicable for crypto-asset service providers on 30 December 2024. Where the end customer or end user is in the EEA, we add GDPR-aligned consent records and retention windows.

For deployments touching the Middle East and South Asia, we map the same controls onto VARA (Dubai), the Central Bank of the UAE crypto framework, the Securities Commission Malaysia DAX guidance and India's PMLA crypto reporting rules. Where local jurisdictions restrict crypto activity, we will refuse the engagement rather than deliver a non-compliant build.

Typical modules per engagement

• Account login, OAuth-style token refresh and device binding
• Wallet balance and staking sub-balance synchronisation
• Trade, swap and conversion history with on-chain hash
• Statement exports to JSON, CSV, Excel and PDF
• Webhook delivery for swap, deposit and withdrawal events
• BscScan reconciliation and missing-transaction alerts

What we deliver

• OpenAPI / Swagger specification covering login, balance, statement and webhook
• Protocol and authorization flow report (token / cookie / signature chain)
• Runnable Python and Node.js source for login and statement APIs
• Automated integration tests, plus golden-file fixtures from real responses
• Compliance pack: consent template, retention policy, FATF and MiCA mapping
• Optional hosted endpoint with pay-per-call billing for low-volume teams

About OpenFinance Lab

OpenFinance Lab is an independent technical studio specialising in mobile-app protocol analysis, OpenData ingestion and authorized API integration. Our engineers come from banks, payment gateways, exchange backends and reverse-engineering teams. We have shipped integrations across UPI, SEPA, PIX, Open Banking UK and a long list of crypto venues, so the AFGCoinExchange engagement plugs into pipelines we already understand end to end.

• Two engagement models: source-code delivery from $300, or pay-per-call API billing
• Full pipeline: protocol analysis → build → validation → compliance handover
• Custom Python, Node.js, Go and Kotlin SDKs and test harnesses on request

Engagement workflow

1. Scope confirmation — list endpoints (login, balance, statement, webhook) and target SDK languages.
2. Protocol analysis and API design — typically 2 to 5 business days.
3. Build and internal validation against real test accounts — 3 to 8 business days.
4. Documentation, code samples and replay-able test fixtures — 1 to 2 business days.
5. Handover, NDA, optional ongoing maintenance retainer.
