Working with WSOL

Some launch configurations on Moono Protocol use WSOL (Wrapped SOL) as the quote currency — for example, the pump.fun configuration. This page explains what WSOL is, how the protocol handles it, and how to optimize your workflow.

What is WSOL?

WSOL is an SPL token representation of native SOL. On Solana, native SOL cannot be used directly in token swap or DeFi transactions — it must first be “wrapped” into an SPL token called WSOL. The process is reversible:

• Wrap — convert native SOL into WSOL (creates a WSOL token account and deposits SOL)
• Unwrap — convert WSOL back into native SOL (closes the token account and returns SOL)

WSOL is always 1:1 with SOL. There is no exchange rate or price difference. The only cost is the Solana transaction fee and a small amount for token account rent (~0.002 SOL).

Two Approaches

Approach 1: Automatic — For Occasional Use

If you are making a single launch or interact with the protocol infrequently, you don’t need to prepare anything. The Moono app handles everything automatically:

1. You initiate a launch or other action requiring WSOL
2. The app detects that you don’t have enough WSOL
3. It automatically wraps the required amount of SOL into WSOL before executing the transaction
4. After the action completes (repay, liquidation), any remaining WSOL can be unwrapped back to SOL

This is the simplest approach — just make sure you have enough native SOL in your wallet and the app does the rest.

Trade-off: each automatic wrap/unwrap adds a small overhead — the Solana transaction fee plus ~0.002 SOL for the temporary WSOL token account rent. For a single launch this is negligible, but it adds up over many launches.

Approach 2: Manual Pre-Wrap — For Frequent Use

If you plan to make multiple launches, provide liquidity, or interact with the protocol regularly, it’s more cost-efficient to wrap SOL in advance:

1. Go to the Profile section in the Moono app
2. Wrap a larger amount of SOL into WSOL (enough for several launches plus fees)
3. Your WSOL balance is now ready — all subsequent launches will use it directly without additional wrap transactions
4. When you’re done, unwrap your remaining WSOL back to SOL in the Profile section

Benefits:

• Lower costs — you pay the wrap/unwrap overhead only once instead of on every launch
• Faster transactions — launches don’t need the extra wrap step, so transactions are simpler
• Better control — you always see your WSOL balance and know exactly how much is available

Recommendation: if you plan more than 2-3 launches, pre-wrapping is worth it. Wrap enough for your planned launches plus fees and interest with some buffer.

Cost of Wrap/Unwrap

Each wrap or unwrap operation requires:

Operation	Cost
Wrap (SOL → WSOL)	Solana transaction fee (~0.000005 SOL) + token account rent (~0.002 SOL)
Unwrap (WSOL → SOL)	Solana transaction fee (~0.000005 SOL); rent is refunded

The token account rent (~0.002 SOL) is charged when creating a WSOL token account and refunded when the account is closed (unwrap). So the net cost of a full wrap → unwrap cycle is just the transaction fees.

Which Launch Configurations Use WSOL?

Currently, the pump.fun launch configuration uses WSOL as the quote currency. Future launch configurations may use different quote assets — each configuration specifies its own quote currency independently.

You can check which quote currency a launch configuration uses in the app before initiating a launch.
