Borrower Guide

Moono lets you borrow quote liquidity to create and seed a pump.fun token. Public launches currently support WSOL and USDC quote pools.

1. Choose a Quote Asset

Quote	Minimum	Maximum	Duration	Notes
WSOL	0.1 SOL	2500 SOL	1-336h	Uses wrapped SOL. The app can wrap native SOL when needed.
USDC	100 USDC	20000 USDC	1-24h	Uses SPL USDC directly. You still need SOL for transaction fees and rent.

WSOL and USDC are separate pools. Loan limits, overhead, migration reserve, and surplus split are read from each on-chain launch configuration; see Economics.

2. Register Your Profile

Create a Moono User Profile once. The same profile is used for borrowing, LP positions, MTrade, launch presets, and the browser service wallet.

3. Prepare a Launch Preset

A launch preset stores your token metadata and bundle settings:

base mint and token metadata
name, symbol, and URI
bundle wallet count and distribution
the selected launch configuration: pump.fun / WSOL or pump.fun / USDC

For pump.fun launches the base token is a Token-2022 mint with pump.fun-compatible supply and decimals. See Launch Presets for the preset workflow.

4. Plan the Launch

Choose:

borrowed quote amount
initial quote buy amount
loan duration
optional bundle wallet buys
optional user co-buy

The app runs preflight and estimator checks before sending. A valid launch is either:

all pre-graduation — total demand stays below the pump.fun migration threshold
cap path — the launch itself crosses the threshold, then Moono migrates and completes the buy on PumpSwap

The app rejects gray-zone flows where a later bundle/user buy would be the trade that graduates the curve.

5. Submit the Ordered Transaction Flow

Every public launch follows this order:

launch_0 / launch_2
launch_migrate_0 / launch_migrate_2
launch_complete_0 / launch_complete_2
optional bundle_buy chunks
optional user_buy last

The _0 family is the WSOL path. The _2 family is the USDC path. The user interface chooses the correct path from the selected launch configuration.

launch_migrate_* and launch_complete_* are included even when migration is not needed. They are idempotent no-ops on normal launches and active on cap-path launches.

6. Manage the Loan

After launch, the initial buy and bundle holdings are loan collateral. You have two main exits.

Repay

Repay returns the borrowed quote to the pool and transfers the collateral base tokens to your wallet. If a preset used bundle wallets, repay also sweeps their base tokens to you and unlocks the preset.

Liquidate / Sell and Liquidate

Liquidation sells collateral on the live venue: pump.fun before graduation or PumpSwap after graduation. Sale proceeds repay the quote vault. Any positive surplus is split:

Recipient	Share
LPs	20.00%
Platform	10.00%
Borrower	70.00%

The split is snapshotted at launch time. If sale proceeds plus reserve are below the borrowed amount, the funding LP ticks take the shortfall through lower NAV.

WSOL vs USDC Behavior

Topic	WSOL	USDC
Quote asset	Wrapped SOL SPL token	SPL USDC
User preparation	Native SOL can be wrapped automatically or ahead of time	User needs USDC balance and SOL for fees
Accounting units	9 decimals, displayed as SOL	6 decimals, displayed as USDC
Public methods	`_0`	`_2`
Migration reserve	WSOL-denominated	USDC-denominated
