transak_skill

Overview

This skill integrates Transak fiat-to-crypto on-ramp and off-ramp capabilities into Web3 apps. It exposes APIs and widget generation utilities to let users buy and sell crypto using 100+ payment methods across 170+ countries. The skill includes examples for price quotes, order status, webhook verification, and widget customization to accelerate integration.

How this skill works

The skill wraps Transak REST endpoints and provides shell examples to fetch supported fiat/crypto, get price quotes, create widget URLs, and poll order status. It also documents webhook payloads and a simple HMAC-SHA256 verification function to validate events. Environment variables are used for API keys and environment selection (staging or production).

When to use it

• You need a simple fiat-to-crypto on-ramp for wallets, NFT checkouts, or DeFi apps.
• You want to display a prebuilt Transak widget tailored to a user's wallet and currency.
• You need to fetch price quotes and supported currency lists for UX flows.
• You want to accept multiple local payment methods across many countries.
• You need off-ramp support to let users sell crypto to fiat.

Best practices

• Store TRANSAK_API_KEY and TRANSAK_SECRET securely on the server; never expose keys client-side.
• Use TRANSAK_ENV to switch between staging and production endpoints during development.
• Verify webhook signatures using HMAC-SHA256 and your TRANSAK_SECRET before trusting payloads.
• Always check order status server-side before granting on-chain assets or unlocking features.
• Validate wallet addresses and supported networks to avoid routing errors.

Example use cases

• Embed a Transak widget URL in a wallet onboarding screen to let users buy ETH instantly.
• Fetch fiat/crypto support to populate a currency selector in a checkout flow.
• Request a price quote server-side to display estimated crypto amounts and fees.
• Handle webhook ORDER_COMPLETED events to credit user accounts after on-chain settlement.
• Offer local payment rails (PIX, UPI, SEPA) in region-specific storefronts.
