🏗️ Colosseum Hackathon 2026 — Encrypt Track — Deployed on Devnet

The privacy layer
AI agents need.

Every AI agent trading on Solana is exposed. Strategies leaked. Alpha copycatted. Shadow Vault hides deposits, withdrawals, and orders behind cryptographic commitments and nullifiers. Not a concept. Deployed. Working. Now.

The Problem

Every AI agent on-chain is naked

Autonomous agents executing trades on Solana expose their entire strategy. Balances, positions, order flow — all visible. All copyable. All front-runnable.

👁️

Strategy Leakage

Every trade is public. Competitors see your agent's positions in real-time and copy your alpha.

🎯

MEV Extraction

Visible order flow gets sandwiched. Your agent loses value to searchers on every execution.

📊

Portfolio Exposure

Wallet balances reveal conviction. Large positions trigger front-running before your agent can act.

How It Works

Three instructions. Total privacy.

Shadow Vault is a Solana program with three core operations. No admin keys. No upgrade authority after deployment. Immutable.

Commit

Deposit SOL with a commitment hash: H(amount || owner || nonce). The amount is hidden. Only the hash is stored.

Execute

Agent trades using encrypted order references. Details are hashed on-chain. Strategy stays private.

Nullify

Withdraw with a nullifier: H(vault || amount || nonce). Unlinkable to any deposit. Double-spend prevented.

Comply

Owner can decrypt order details and share with regulators. Selective disclosure without full exposure.

Why Shadow Vault

The only project at this intersection

Privacy for AI agents isn't a niche — it's the gap nobody filled. Shadow Vault is the first to combine encrypted vaults with AI agent strategy protection on Solana.

Get Started

Three steps to private trading

🔗

Connect Wallet

Phantom, Solflare, or any Solana wallet

→

🔐

Create Vault

Initialize your encrypted pool on-chain

→

🤖

Deploy Agent

Connect your agent via TypeScript SDK

For Developers

Integrate in 5 minutes

Shadow Vault ships with a TypeScript client SDK. Three methods: init, deposit, withdraw. Works with any Solana agent framework.

View on GitHub →

          src/devnet-client.ts
          TypeScript
        

import { ShadowVaultClient, generateNonce } from '@shadow-vault/solana';

// Connect to devnet
const vault = new ShadowVaultClient(owner);

// Deposit — amount HIDDEN on-chain
const dep = await vault.deposit({ amountSol: 0.1 });

// Execute encrypted order — details HIDDEN
await vault.executeOrder({
  details: { pair: 'SOL/USDC', side: 'BUY' },
  encryptionKey: generateNonce(),
});

// Withdraw — UNLINKABLE to deposit
await vault.withdraw({ vaultId, amountSol: 0.1, nonce: dep.nonce });
