Spend approval
Let the ghost spend from your own wallet, up to a limit.
If you'd rather keep your funds in your own wallet, you can grant SpendGhost a spend approval instead of depositing. You sign once, off‑chain, and the ghost can then debit USDC from your wallet — up to a cap you choose — when you place an order.
How it works
Connect your wallet
From your dashboard, connect the wallet you want to spend from.
Sign an approval
Sign a USDC spending approval (a gasless EIP‑2612 / EIP‑3009 permit). This is a signature, not a transaction — it costs you no gas.
Set your limit
Choose the amount you're comfortable authorizing.
After that, your available balance is simply what you've approved (up to what's in your wallet). The ghost debits it as you buy, and never more than your cap.
Why it's safe
Approval vs. deposit
Both end at the same place — a balance the ghost can spend. Deposit moves USDC into your SpendGhost wallet; approval leaves it in your own wallet until an order debits it. Pick whichever you prefer; see How funding works.
