Today's bags on sale
Every listing is checked on-chain before it shows: the seller really holds the bag and owns the deal account. Discounts are against the live chart price.

Put your bag on sale
Dumping a big bag on the chart pushes the price down while you sell. Listing it here gets you one fixed price, from one buyer, in one swap. The chart never sees it.

Keep this tab open while your bag is on sale: buyers ask here and you sign their deal with one tap.

The chart shows price. This shows the wallets behind it: groups funded by the same wallet, bundlers, wallets made after launch, KOLs and the dev's record.
04 · How it works
One swap. Two signatures. Nobody holds the money.
- 1Seller listsBag, price and timer go up on public Nostr relays. Free to read, no server of ours.
- 2You tap GrabFree, no approval. The seller's tab gets your wallet address.
- 3Seller signs your dealLocked to your wallet. A durable nonce keeps it valid until you use it or they cancel.
- 4You check and approveWe re-check the live price and the seller's balance, then you approve once.
- 5One transactionYour SOL goes to the seller and the bag comes to you, together or not at all.
Inside the transaction you approve
#0Use up the seller's deal account, so this deal works once#1–2Network fee settings (about 0.000015 SOL)#3Send the price in SOL: you → seller#4Open your token account if you don't have one yet#5Send the bag: seller → you
All or nothing. If any step fails (the seller sold the bag somewhere else, you're short on SOL) nothing moves and you only pay the network fee.

FAQ
Straight answers
Can a seller run off with my SOL?
No. Your SOL and their tokens move in the same transaction. If their side fails, yours never happens. There's no escrow and no wallet of ours in the middle.
Why does the seller have to be online?
A Solana signature covers the exact transaction, buyer included, so the seller signs once they know it's you. Their tab pings them when you tap Grab. If they're away, your request just waits.
What's a durable nonce and why the 0.001 SOL?
Normal transactions expire after about a minute. A nonce account lets the signed deal wait for you. It holds a small rent deposit that goes back to the seller when they close the shop. Closing it also kills every deal they signed.
Does the countdown stop a signed deal?
The countdown takes the bag off the board and stops new deals. A deal already signed stays valid until it's used or the seller closes the shop, so sellers should close when they're done.
Is a discount always a good deal?
No. A bag can be cheap because holders know something. Run Bag check first: if the seller is part of a wallet group still holding a lot, or the dev launched 40 coins this week, price that in.
Who runs the board?
Nobody owns it. Listings are public Nostr posts and anyone can post one. That's why this page checks every listing against the chain before showing it, and checks the deal again before you sign.
