How it works
A single core in Node.js and TypeScript serves ten networks: address generation, key encryption with AES-256-GCM derived through HKDF, and detection of incoming payments by polling blocks — and for Bitcoin through a ZeroMQ subscription to the node.
The confirmation threshold is set per network. Incoming funds are checked for origin by two external AML providers. The rate into local currency is computed automatically from the P2P order books of exchanges, and the margin tunes itself.
Storage is a fault-tolerant PostgreSQL setup with a balancer and geo-replication. The scale: a 283 GB database and more than 85 million operations. Alongside it there is a separate product — a P2P exchange with escrow, dispute arbitration and participant reputation.
