What it does

​

What you can build

• Confidential payroll - stream salaries to employees and contractors without publishing compensation onchain.
• Confidential merchants - let merchants accept fast, low-cost stablecoin payments without leaking revenue or supply chain counterparties.
• Confidential token launches and OTC - let participants receive or trade tokens confidentially.
• Web wallets with confidential transfers built in - give everyday users privacy by default for transactions and balances.
• Agentic confidential payments - enable fast, confidential micropayments for subscriptions, APIs, or AI agents.
• Treasury management - let enterprises, funds, and market makers move capital without broadcasting strategy to the market.
• Confidential RWAs - trade onchain stocks, tokenized funds, or bitcoin without leaking activity, similar to how private financial activity works offchain.

Quick Start: Code Snippets

import { ConfidentialTransferClient } from '@fairblock/stabletrust';
import { ethers } from 'ethers';

// Example: Base Sepolia setup
const client = new ConfidentialTransferClient(
  'https://sepolia.base.org',
  84532
);

// signer is a standard ethers.js Signer
const { privateKey, publicKey } = await client.ensureAccount(signer);

const tokenDecimals = 6;
const depositAmount = ethers.parseUnits('1.0', tokenDecimals);

await client.confidentialDeposit(signer, tokenAddress, depositAmount);

const transferAmount = ethers.parseUnits('0.5', tokenDecimals);

await client.confidentialTransfer(
  signer,
  recipientAddress,
  tokenAddress,
  transferAmount
);

const balance = await client.getConfidentialBalance(
  signer.address,
  privateKey,
  tokenAddress
);

console.log(
  'Total Confidential Balance:',
  ethers.formatUnits(balance.amount, tokenDecimals)
);
