Non-Custodial Cryptographic Policy

Security & Key Safety

Probl adheres to strict non-custodial Web3 principles and zero-trust AI permissions.

✓

1. 100% Non-Custodial Wallet Signing

Probl never holds user private keys, seed phrases, or custody of funds. All transactions (Buy, Sell, Launch, Claim Cashback) must be explicitly approved and signed inside the user’s self-custody wallet (MetaMask, Rabby, Rainbow, Coinbase Wallet).

🛡️

2. AI Zero-Authority Guarantee

Claude and our AI abstraction layer operate in strict read-only analytical mode. Claude NEVER receives private keys, and has ZERO cryptographic authority to sign or initiate fund transfers on behalf of any user or smart contract.

🔒

3. Server-Side Secret Isolation

Anthropic API credentials (ANTHROPIC_API_KEY) are securely isolated in serverless runtime environments. Client-side browser code never has access to backend secrets or privileged RPC relay endpoints.

⚡

4. Smart Contract Anti-Snipe Decay

The bonding curve enforces an automated 3-second block fee decay (99% → 24.8% → 5.2% → 0%) preventing predatory MEV sandwich bots and sniper scripts from cornering community token launches.
