Build confidential
applications.

XELIS Vault is MIT-licensed, fully open source, and built to be extended. The wallet protocol (XSWD) is a simple JSON-RPC WebSocket. The contract language (Silex) is Turing-complete. Below is everything you need to ship a confidential DeFi app — repositories, examples, and bounties for the work that still needs doing.

Code examples

Working snippets you can paste into a dApp. All entry IDs and parameter formats are real.

Connect to wallet via XSWD

Open a WebSocket to the local wallet daemon and request permissions.

const ws = new WebSocket('ws://localhost:44325/xswd')

ws.onopen = () => {
  ws.send(JSON.stringify({
    id: 'my-dapp-' + Math.random().toString(36).slice(2),
    name: 'My XELIS App',
    description: 'Built on XELIS Vault',
    url: window.location.origin,
    permissions: [
      'get_balance',
      'get_address',
      'build_transaction',
      'transfer',
    ],
  }))
}

Open a vault (deposit + borrow)

Call VaultEngine.deposit entry function with XEL collateral and borrow xUSD.

// entry_id 10 = VaultEngine.deposit
// params: [collateralAsset, collateralAmount, borrowAmount]
const tx = await wallet.callContract(
  VAULT_ENGINE_ADDRESS,
  10,
  [
    { type: 'Hash', value: XEL_ASSET_HASH },
    { type: 'U64',  value: '100000000000' }, // 100 XEL
    { type: 'U64',  value: '50000000000'  }, // 500 xUSD
  ]
)

await wallet.sendTransaction(tx)

Submit oracle price (as miner)

If you are a registered miner, submit the latest XEL/USD price.

// entry_id 5 = StakedOracle.submit_price
// params: [price (u64), timestamp (u64)]
const tx = await wallet.callContract(
  STAKED_ORACLE_ADDRESS,
  5,
  [
    { type: 'U64', value: '1294' }, // $12.94
    { type: 'U64', value: String(Math.floor(Date.now() / 1000)) },
  ]
)

await wallet.sendTransaction(tx)
