Please ensure to first remove all Roles and Rules within the app to recover 100% of your SOL, otherwise you won’t be able to delete the Rules and Roles after deleting the app.

Minimum example on how to delete an app using plain Javascript:

import { Keypair, PublicKey, Connection, clusterApiUrl} from "@solana/web3.js";
import { solCerberus, getProvider } from "sol-cerberus-js";
import * as anchor from "@project-serum/anchor";


/** Create a connection. **/
const connection = new Connection(clusterApiUrl("mainnet-beta"), "confirmed");
/**  NOTE: Replace the following Uint8Array by your own wallet private key **/
const wallet = Keypair.fromSecretKey(Uint8Array.from([174, 47, ...]));
 
const solCerberus = new SolCerberus(connection, wallet, {appId: new PublicKey("PASTE_YOUR_SOL_CERBERUS_APP_ID_HERE")});
// Delete existing Sol Cerberus app on-chain:
await solCerberus.deleteApp() // Async func

With React:

Small example on how to delete an existing app with React:

import React, { startTransition, useEffect, useState } from "react";
import { useConnection, useWallet } from "@solana/wallet-adapter-react";
import { SolCerberus } from "sol-cerberus-js";
import { PublicKey } from "@solana/web3.js";

export default function MyReactComponent({ router }) {
  const [solCerberus, setSolCerberus] = useState<SolCerberus | null>(null);
  const { connection } = useConnection();
  const { publicKey, wallet } = useWallet();
  const [app, setApp] = useState(null);

  const clearStates = () => {
    if (solCerberus) {
      solCerberus.disconnect(); // Remove Websockets listeners
      startTransition(() => setSolCerberus(null));
    }
  };

  const getAppData = async () => {
    const appData = await solCerberus.getAppData();
    startTransition(() => setApp(appData));
  };

  const handleDeleteApp = async () => {
    await solCerberus.deleteApp();
    startTransition(() => setApp(null));
  };

  // STEP 1: Init Sol Cerberus
  useEffect(() => {
    // Clear all data when user's wallet has been disconnected
    if (!publicKey) {
      return clearStates();
    }
    if (solCerberus) return;
    startTransition(() =>
      setSolCerberus(
        new SolCerberus(connection, wallet, {
          appId: new PublicKey("PASTE_YOUR_SOL_CERBERUS_APP_ID_HERE"),
        })
      )
    );
    return () => clearStates();
  }, [publicKey]);

  // STEP 2: Fetch app data
  useEffect(() => {
    if (!solCerberus) return;
    getAppData();
  }, [solCerberus]);

  return (
    <div>
      {!!solCerberus && (
        <div>
          {!!app && (
            <button onClick={handleDeleteApp}>
              Delete app: {solCerberus.appId.toBase58()}
            </button>
          )}
          {!app && <div>APP already deleted.</div>}
        </div>
      )}
    </div>
  );
}
