Deposit, watch a cycle, withdraw. 3 minutes.

ESEC is live on devnet at FxausMaH3TWJkUeVPpLbYY55rVMztSKr6KtZ1jRFdrRw. The SDK is an alpha TypeScript client. Get devnet USDC, deposit, watch a cycle on the dashboard, withdraw.

1. Install the SDK

npm install @esec/sdk @solana/web3.js

2. Connect

import { EsecClient } from "@esec/sdk";
import { Connection, Keypair } from "@solana/web3.js";

const connection = new Connection("https://api.devnet.solana.com");
const wallet = Keypair.fromSecretKey(/* your secret */);

const cascade = new EsecClient({
  connection,
  wallet,
  cluster: "devnet",
});

3. Deposit

// Deposit 100 USDC into the SOL cluster vault.
// LP tokens (CASC-SOL) are minted to your wallet pro-rata.
const sig = await esec.deposit({
  asset: "USDC",
  amount: 100 * 1e6, // raw token units, USDC has 6 decimals
});

console.log("deposit tx:", sig);

4. Watch a cycle

// Subscribe to cluster signals + vault state transitions.
cascade.subscribeReceipts((receipt) => {
  console.log("cycle close:", {
    asset: receipt.asset,
    deployPrice: receipt.deployPrice,
    exitPrice: receipt.exitPrice,
    pnl: receipt.pnlSigned,
    reason: receipt.reason, // "Recovery" | "StopLoss" | "Timeout"
    durationSlots: receipt.exitSlot - receipt.deploySlot,
  });
});

5. Withdraw

// Burn 50 CASC-SOL, receive USDC pro-rata minus 0.1% withdraw fee.
const sig = await cascade.withdraw({
  asset: "USDC",
  lpAmount: 50 * 1e6,
});

console.log("withdraw tx:", sig);
