PAYDOWN Launch a coin
001Launch #001: a Kamino loan gets paid off

Your coin pays off someone's loan.

Launch on Pump.fun, point creator fees at the PAYDOWN vault, and nominate a real Solana loan: a Kamino, marginfi or Save position that's underwater. Every trade fills the meter. When it's full, the vault repays the loan on-chain. The repayment transaction is the receipt.

Launch a coinHow the money moves

Solana lending protocols where a third party can repay a position on the borrower's behalf. The vault repays straight from the protocol's own repay instruction; PAYDOWN never touches the borrower's wallet.

Who's getting paid off

Only coins the bot has verified on-chain appear here. First payoff: Launch #001.

The mechanic

How it works

No custom contract. Pump.fun's own creator-fee sharing moves the money, the lending protocol's own repay instruction pays the loan, and an open-source bot does the bookkeeping in public.

STEP 1

Nominate a loan

Paste a Solana wallet with an open loan on Kamino, marginfi or Save. Yours, a holder's, a stranger's.

STEP 2

Launch on Pump.fun

Open Creator fee sharing and give the vault at least 50%. Saving locks the split.

STEP 3

Get listed

Submit your mint. The bot reads the lock on-chain before your coin hits the board.

STEP 4

Fill the meter

Every trade pays creator fees. The bot pulls them into the vault every 15 minutes.

STEP 5

Loan paid off

At 100% the vault repays the position on-chain. The repay transaction goes on the card. Then the next nominee.

Launch post

By launching you create the coin from your own wallet; you're its creator. PAYDOWN never holds your keys and never touches the borrower's wallet: repayments go straight to the lending protocol.

Don't trust, verify

Check every address yourself

Fees move through Pump.fun's own programs into one public multisig. The bot that tracks them is open source, and its ledger is a file anyone can read.

Questions

Before you ape the idea

How can you repay someone else's loan?

Solana lending protocols let any wallet repay a position on the borrower's behalf: the repay instruction takes the borrower's obligation account and the repayer's tokens. The vault calls it with the coin's meter. Nothing is taken from the borrower, nothing is sent to their wallet, the debt just goes down.

Who picks the loan?

The dev nominates a wallet at launch. It can be their own, a holder's, or a stranger's. The bot reads the position on-chain, sets the meter to the debt, and refuses wallets with no open borrow.

What if the position gets liquidated first?

Then there's nothing to repay. The meter rolls to the next nominee the dev listed, or to a buyback if that's what they chose. Funds never leave the vault except to a lending protocol or a buyback.

Can the dev change the split after launch?

No. Pump.fun lets a coin set its fee shares once, then revokes the authority on-chain. The bot won't list a coin until it reads that lock.

Who holds the vault?

A multisig, published above. Every inflow and every repayment is in the public ledger with its transaction signature.

What does PAYDOWN earn?

10% of what reaches the vault, disclosed in the code. $PAYDOWN is the project's own Pump.fun coin; its creator fees go to the team.

Is this a lender? Is it investment advice?

No and no. PAYDOWN never lends, never charges interest, never holds anyone's collateral. It repays existing loans with meme-coin fees. Memecoins are extremely risky and most go to zero.

House rules

What we won't do

Loans only

Vault money goes to a lending protocol's repay instruction or a buyback. Nowhere else, ever.

No lending, no interest

PAYDOWN pays debts down. It never gives loans, never takes collateral.

Everything is a tx

Nomination, verification, repayment: each one is a transaction you can open on Solscan.
