Tachyon is a privacy-native cross-chain payment protocol. Submit a signed intent describing what your user wants, “send 1,000 USDC from Arbitrum to this address on Base”, and Tachyon delivers it confidentially. Sender, recipient, amount, and route stay private end-to-end.

Quickstart

Submit your first intent via the SDK in five minutes.

Concepts

How integration looks

// Planned SDK surface. Today: createIntent on-chain + POST /store-recipients.
const { intentId } = await tachyon.intent.submit({
  sourceChain: "base_mainnet",
  destChain:   "horizen_mainnet",
  tokenIn:  USDC_BASE,
  tokenOut: USDC_HORIZEN,
  amountIn:     1_000_000_000n,
  minAmountOut:   999_000_000n,
  reward:          50_000_000n,
  deadline: Math.floor(Date.now() / 1000) + 600,
  recipients: [{ address: "0xRecipient...", amount: 999_000_000n }],
}, wallet);
The recipient’s app auto-sweeps from the destination stealth address. Done.
