Getting Started

How to Get API Key

1 Login to Daemon Protocol

Visit daemonprotocol.com and login with your Solana wallet.

Security

All transactions are secured by Solana blockchain. API keys are required for balance checks and LLM access. Never share your private keys or API keys with anyone.

How to Top Up Credits

Payment Methods

You can top up your credits using any of these tokens on Solana:

  • SOL - Native Solana token
  • USDC - USD Coin stablecoin
  • USDT - Tether stablecoin

Step-by-Step Guide

1 Enter Your Wallet Address

Input your Solana wallet address in the Payment section. This will be used as a reference for tracking your payment.

2 Select Token & Amount

Choose your preferred token (SOL/USDC/USDT) and enter the amount. The system will automatically calculate the USD value and credits you'll receive.

3 Create Payment Request

Click "Create Payment" button. A QR code will be generated with the payment details.

4 Scan & Pay

Scan the QR code with your Solana wallet (Phantom, Solflare, etc.) or click "Open Wallet" button. Confirm the transaction in your wallet.

5 Wait for Confirmation

The system will automatically detect your payment and add credits to your account. This usually takes 10-30 seconds.

Tips

  • Minimum payment: 0.01 SOL or equivalent
  • Credits = USD value (1 USD = 1 Credit)
  • Transactions are final and cannot be reversed
  • Keep your transaction signature for records
