Build it on primitives

Common products teams ship on 1st Node — each assembled from composable primitives on a single key.

Crypto AML & compliance API

Embed AML into your product with one API: address risk-score, KYT transaction screening, sanctions checks and multi-hop fund-flow tracing, metered by credits.

Wallet infrastructure API

Build wallets on one API: balances, net-worth, approvals, transaction simulation plus create, sign and broadcast — across BTC, ETH and TRON.

Crypto payments API

Accept and send crypto with one API: invoices, checkout, deposit detection, mass payouts and settlement — with AML screening on the same key.

On-chain data API for trading

Power a trading terminal with one API: spot and OHLCV prices, DEX trades and pools, smart-money flows and decoded on-chain data.

Blockchain intelligence API

Query on-chain intelligence as an API: entity clusters, wallet labels, counterparty graph, path-finding and smart-money signals.

Transaction monitoring (KYT) API

Know-Your-Transaction as an API: screen transfers in real time, score counterparties and trace fund flow to meet AML monitoring obligations.
