How it works
Post the coin on X. Its creator fees go to the people who post it.
A coin launches here
Anyone launches a Pump.fun coin from their own wallet. The launch points the coin's creator fees at a payout wallet that belongs to that coin, so the launcher cannot take them and cannot change it later. Every ticker exists once on Postbag.
You post the coin
Open your X feed on this site and quote or reply to any post with a coin attached, or write a new post from the coin's page. It goes out from your own X account. Posts written on X directly count too, as long as they include the coin's contract address.
Posts earn points
Every view is 1 point, every like is 25 and every repost is 100. These are the same numbers X shows under the post. A repost of someone else's post earns nothing for you, so write your own post or a quote.
Fees are split by points
Every few minutes the coin's creator fees are collected and split between everyone who posted it, by the new points their posts gained since the last split. Five times the points gets five times the SOL. When nobody gained points, the fees wait for the next round.
You claim it
Your share is booked to your X account from the first split. On your page, sign in with X, add a Solana wallet and claim everything at once. Solana's network fee comes out of the claim.
What nobody claims is burned
Claim within 7 days. After that, 75 percent of an unclaimed share is set aside to buy back and burn the coin it came from, and 25 percent to buy back and burn the Postbag token.
It is all on chain
Every collection and claim is a Solana transaction, listed in the ledger.
What makes a post count
- It includes the coin's contract address. A ticker alone is not enough, so a post about some other $CAT never takes this coin's fees.
- It was posted after the coin launched.
- It is your own post, quote or reply, from a public account.
