Set Up Your Wallet
Sandbox GHI runs on Solana. You need a Solana wallet to mint, stake, and receive $GHI rewards.
Supported Wallets
Phantom is the most popular Solana wallet — available as a browser extension and mobile app.
- Go to phantom.app (opens in a new tab)

- Click Create New Wallet
- Save your Secret Recovery Phrase — 12 or 24 words. Store it offline.
- Set a password
Your Phantom wallet is ready.
🚫
Never share your seed phrase. Anyone who has it can drain your wallet. Sandbox GHI will never ask for your seed phrase.
Fund Your Wallet
You need at least 0.031 SOL to mint one NFT:
- 0.03 SOL — mint price
- ~0.001 SOL — Solana transaction fees
Where to buy SOL
- Coinbase (opens in a new tab) — easiest for beginners
- Binance (opens in a new tab) — lowest fees
- Any CEX that supports Solana withdrawals
After purchasing, withdraw SOL to your wallet address (starts with a letter, ~44 characters).
Verify Your Wallet
Once funded, your wallet is ready. When you visit sandboxghi.xyz (opens in a new tab) and click Connect Wallet, your wallet extension will ask you to approve the connection — click Connect.
