FAQ

Do I need a custom token?

Not necessarily. You can use Wrapped SOL (default) as collateral — just wrap SOL when depositing. Custom tokens are useful for testing stablecoin-margined markets.

Do I need tokens in my wallet?

Yes. To deposit into a Percolator market, you need tokens of the collateral mint in your wallet. This page mints them directly to you.

What about Wrapped SOL?

If your market uses Wrapped SOL as collateral (the default), you don't need to mint anything — the Launch Wizard handles wrapping SOL automatically.

Can I mint more later?

Yes, use the "Mint More" section below. You must be the mint authority (the wallet that created the token).
