Practical, step-by-step guides for building crypto payments and blockchain apps on our APIs — non-custodial by design, across 20+ blockchains. Every guide leads with real requests you can run today.
Accept and move crypto without giving up your keys — the API handles the public data and the heavy lifting; you sign offline.
Take Bitcoin, Ethereum and stablecoin payments to an address you control — single-address or per-order — watch for payment with a webhook, and sweep by signing offline.
Read the guide →Auto-forward incoming deposits to your treasury without a custodian — watch, prepare an unsigned sweep, sign offline and broadcast, on a loop. Your keys never leave your infrastructure.
Read the guide →Build wallets and react to on-chain activity in real time — non-custodial, no nodes to run.
Ship a wallet where users keep their keys — derive addresses from an xPub, track balances and transactions across 20+ chains, and send by signing offline.
Read the guide →Get a real-time callback the moment an address receives a payment, a token transfer or a new block — no polling, no node.
