Quick start
Settle your first invoice on the FTR rail in three steps. You'll need a self-custody wallet and a Whitechain RPC endpoint.
1 · Install the SDK
Add the FTR client to your project. It wraps settlement, collateral, and rewards calls behind one typed interface.
$ npm install @ftr/client
2 · Connect a wallet
Point the client at Whitechain Sepolia (the live public testnet, chain ID 1874) and your signer. Amounts are denominated in FTR at the $0.01 utility reference.
Gas is paid in WBT — claim free test WBT from the Whitechain faucet. Whitechain mainnet is not live yet; its parameters are published before launch.
import { FTR } from "@ftr/client"; const ftr = new FTR({ rpc: "https://rpc.testnet.whitechain.io", chainId: 1874, signer, });
3 · Settle an invoice
Call settle() with the counterparty and amount. Settlement confirms in about a second; full finality follows L1 settlement.
await ftr.settle({ to: "0x8Af…12E4", amount: "12_400", ref: "INV-0042", });
FTR is a utility token used to operate the rail. Nothing in these docs is financial advice or a promise of price or return.
FAQ

Settlements confirm on Whitechain in about a second (1s block time); full finality arrives once the batch settles on Ethereum.
Collateral you lock (FTR, USDC, wBTC) backs your credit line. Positions liquidate on-rail below a 1.05× ratio — a mechanical threshold, not a forecast.
No. FTR is a utility token used to operate the rail. Amounts are denominated at the $0.01 utility reference; nothing here is financial advice or a promise of price or return.
