Credit Purchases

When you buy credits, you sign a transaction that:

• Sends exact amount of SOL/USDC to ZYBER payment address

• Specifies exact token amount (no "unlimited")

• Shows clear recipient and amount in wallet

Always verify the recipient address and amount before signing.

Never sign if you see:

• Unlimited token approval requests

• Unknown contract addresses

• Transactions you didn't initiate

• Amounts that don't match your action
