Signed price quotes for Solana coins
Put your price in writing, signed by your wallet.
Write a price you are willing to buy or sell a coin at, sign it with your wallet, and send the link. Anyone who opens it can see it is really from you, when it runs out, and how it compares with today's market price.
The signature is an Ed25519 wallet signature checked inside the browser. Nothing is sent to us, and no money moves.
Coin address
Sample stamp. Price shown is live from Jupiter; the fingerprint is the real SHA-256 of the stamp's text.
How it works in 3 steps
- 1
Write your price
Pick a coin, buy or sell, how many and at what price.
- 2
Sign it in your wallet
Your wallet signs the text. We never see your keys.

Send the link or QR
They open it and see: real, still valid, and versus market.
Signing a quote is free and moves nothing. The only thing that ever costs a fee is the optional on-chain postmark, and only if you approve it.
Counter 1 · Write
Write and sign a quote
What this does: turns your price into a short signed note you can send to anyone, with the live market price shown next to it.
Your signed quote appears here, ready to copy, share as a link or show as a QR code.
Counter 2 · Check
Check a quote someone sent you
What this does: tells you whether a quote really comes from the wallet it names, whether it has run out, whether that wallet holds what it offers, and how far the price is from the market.
Counter 3 · Market
What would the open market pay right now?
What this does: asks Jupiter's live router what you would get for the same size on the open market, so you can tell whether a quote is a good deal.
The live route, the price you would really get, and the price impact of your size show up here.
The route of one quote
From your wallet to their screen, nothing in between holds anything.
- Write. The quote is plain text: coin, side, size, price, expiry, who it is for.
- Sign. Your wallet turns that text into a 64-byte signature only your key could make.
- Send. Text, signature and address travel together inside a link or a QR code.
- Check. Their browser re-does the maths, reads the live price and stamps a verdict.
Counter 4 · Postmark
Postmark a quote on chain, or read a postmark
What this does: optionally writes your quote's fingerprint into a public Solana Memo, which proves the quote existed at that moment. You can also read any memo transaction.
Postmark my last quote
Sign a quote first (Counter 1). Its fingerprint will show here.
Read a postmark
Counter 5 · My desk
Your desk: what you hold, what you have quoted
What this does: reads the coins in a wallet from mainnet so you can quote one in a click, and keeps your signed quotes in this browser with a live countdown.

Tokenomics
The coin, plainly
Status: planned. No coin has been launched yet; this is the structure it will follow.
0fixed supply
0%sold to anyone on the public bonding curve (no presale)
0%paired as pool liquidity at graduation, then locked or burned
0%team allocation. The team only holds what it buys on the curve like anyone else
- Mint authority: off (no new coins can ever be made)
- Freeze authority: off (no one can freeze your coins)
- No promises of returns. Holding the coin gives no rights over quotes or this site.
Bonding curve split shown is the standard curve launch: about 793M tokens sold on the curve, about 207M added to the pool.
Questions
Straight answers
What is this, in one sentence?
A way to put a buy or sell price for a Solana coin in writing, signed by your wallet, so the person you send it to can check it is genuine.
Is it safe? Does it touch my money?
Signing a quote only signs a piece of text; it cannot move coins and costs nothing. The page never asks for your seed phrase and never holds funds. The one optional exception is the on-chain postmark: a Memo transaction you review and approve yourself, which costs a network fee of about 0.000005 SOL and moves nothing else.
Is a signed quote a binding trade?
No. It is a signed statement of intent. A real swap between two people needs an escrow that holds both sides until both are in, and we have not built one. Use a quote to agree on a price, then settle through a tool you trust.
Can someone fake a quote with my name on it?
They can type anything, but they cannot produce your wallet's signature. The checker recomputes the signature against the address in the quote; if one character was changed, it fails. Try the "change one letter" button on Counter 2 to see it happen.
Why does my wallet show a message to sign?
That is the quote text itself. Read it: it should list the coin, the amount, the price and the expiry. If it says anything else, do not sign.
Which numbers are live and which are estimates?
Prices and the market route come live from Jupiter. Balances and memos are read live from Solana mainnet. The price gap is simple arithmetic on those; the "fair" band on the gauge is our own rule of thumb (within 2%), not advice.
Where are my quotes stored?
Only in this browser, and inside the links you choose to send. Nothing is uploaded to us. Clearing your browser data removes the list, not the quotes you already sent.
Is there a coin?
Not yet. The Tokenomics section shows the planned structure. If one launches, its address will appear at the top of this page and nowhere else is official.
