Cryptrac
Crypto payment platform for businesses.
The project
Most crypto payment tools either custody funds (which is a regulatory and trust problem) or force merchants to stitch together five different SDKs to accept a single coin. Cryptrac is the thing merchants actually want: one link, any chain, money in your wallet, no intermediary.
The approach
Non-custodial by architecture — Cryptrac never holds customer funds or merchant private keys. That constraint shapes every design decision, from how checkout flows work to how wallets connect, not just the marketing copy.
One unified payment link that accepts 82+ cryptocurrencies across multiple networks, with automatic network detection and routing so merchants don't need to think about chains, tokens, or wallet compatibility.
Stripe-style developer experience — clean dashboard, shareable checkout URLs, webhooks, real-time tax via TaxJar, and subscription billing — all in a Turborepo monorepo with shared types across marketing site, dashboard, checkout, and API.
