Borrower Guide

This guide walks you through the process of borrowing SOL from Moono Protocol to launch a token on pump.fun.

Prerequisites

• A Solana wallet (Phantom, Solflare, or any compatible wallet)
• SOL in your wallet to cover fees and interest (see Economics for exact costs)
• Token metadata ready: name, symbol, and image URI

Step 1: Register Your Profile

Before your first loan, you need to create a User Profile on the protocol. This is a one-time action.

• Connect your wallet to the Moono app
• Click Register (or the profile creation action)
• Approve the transaction — this costs 0.01 SOL (registration fee) plus a small amount for Solana account rent

Your profile tracks your loan history and assigns sequential loan IDs.

Step 2: Configure Your Loan

Choose your loan parameters:

Loan Amount

Select how much SOL you want to borrow. This determines how much SOL goes into buying your token on the pump.fun bonding curve.

	Min	Max
Loan Amount	0.1 SOL	10 SOL

A larger loan means a bigger initial buy on pump.fun, which pushes the token price higher on the bonding curve from the start.

Loan Duration

Choose how long you need the loan:

	Min	Max
Duration	1 hour	24 hours

You must repay within this window, or your loan becomes eligible for liquidation.

Token Details

Provide the metadata for your new token:

• Name — the full token name (e.g., “Moono Cat”)
• Symbol — the token ticker (e.g., “MCAT”)
• URI — link to the token metadata JSON (image, description, etc.)

Step 3: Review Costs

Before confirming, review the total cost breakdown:

1. Protocol Fee — 0.01 SOL (fixed)
2. Migration Reserve — proportional to loan size (see Economics)
3. Launch Overhead — 0.05 SOL (refundable)
4. Interest — depends on loan amount, duration, and current liquidity utilization

You pay the interest + fees upfront from your wallet. The borrowed SOL goes entirely into the pump.fun token purchase.

Note

Launch configurations that use WSOL as the quote currency (such as pump.fun) require WSOL for fees and interest. If you don’t have enough WSOL, the app will automatically convert the required amount from your native SOL balance. For frequent launches, consider pre-wrapping SOL to save on overhead — see Working with WSOL for details.

Tip

Check the Economics page for detailed cost examples at different loan sizes and durations.

Step 4: Launch

Confirm the transaction. In a single atomic transaction, Moono Protocol will:

1. Deduct fees and interest from your wallet
2. Borrow SOL from the liquidity pool (starting from the lowest-cost ticks)
3. Create your token on pump.fun
4. Execute the initial buy on the pump.fun bonding curve
5. Store the purchased tokens as collateral in a program-controlled escrow

After the transaction confirms, your token is live on pump.fun and tradeable by anyone.

Step 5: Manage Your Loan

Once your token is launched, you have two options:

Option A: Repay the Loan

Before the loan expires, you can repay to recover your collateral tokens:

1. Ensure your wallet has enough SOL to cover the repayment amount
2. Click Repay on your active loan
3. Approve the transaction

On repayment:

• The borrowed SOL is returned to the liquidity pool
• Your collateral tokens (the tokens bought on pump.fun) are transferred to your wallet
• The refundable launch overhead (0.05 SOL) is returned to you
• The loan is marked as Repaid

Option B: Let It Be Liquidated

If you don’t repay before the deadline, the loan becomes eligible for liquidation:

• You can trigger the liquidation yourself, or the protocol admin will do it
• The collateral tokens are sold on the pump.fun bonding curve
• Proceeds go to repay the liquidity pool
• You lose the collateral tokens, but you don’t owe anything extra

Caution

Once a loan expires, liquidation can happen at any moment. There is no grace period. If you want to keep your tokens, repay before the deadline.

Loan Statuses

Status	Meaning
Open	Loan is active; you can repay before expiration
Repaid	You repaid the loan and recovered your tokens
Liquidated by User	A user (could be anyone) triggered liquidation after expiry
Liquidated by Admin	Protocol admin triggered liquidation

Tips

• Start small — try a 0.1 SOL loan first to understand the flow
• Watch the clock — set a reminder before your loan expires if you plan to repay
• Check liquidity — if lower ticks are depleted, your loan will use higher ticks (more expensive)
• Factor in all costs — the interest is just one part; don’t forget the protocol fee and migration reserve
