Overview

Notara is a launchpad for coins on Solana. Any wallet can create one, and from the transaction that creates it the coin trades on a bonding curve of its own.

What runs it

• Meteora's Dynamic Bonding Curve program does the on-chain work on Solana. It creates each coin, keeps the SOL of every curve and executes every trade, all through one configuration account: the Notara launchpad. Notara runs no program of its own.
• An indexer follows the launchpad and feeds the lists, charts, history and Zcash states shown on these pages. The price of a trade always comes from the curve itself.

Get ready

1. A Solana wallet in your browser

   Any wallet that announces itself to the page through the Wallet Standard works, and Notara shows the name and icon that wallet gives. With one wallet installed, Connect goes straight through. With several, a short list lets you choose. With none, the button points to a wallet directory. On a phone, open this site inside your wallet app's own browser.

2. Nothing to switch

   Your wallet signs for whichever cluster the page uses, so there is no network to add or change. This page uses Solana development network.

3. SOL in the wallet

   Launches and buys are paid in SOL, as is the small amount Solana charges to process a transaction. Keep a little spare: the panels reserve 0.01 SOL when they check your balance.

Every transaction is approved in your own wallet. Notara never needs your seed phrase or private key, and nothing on this site asks for them.

Your first coin

Connect a wallet and open the Launch page. The form walks through these parts.

1. Name and ticker

   A name of up to 32 characters and a ticker of up to 10, made of letters, digits, spaces and plain punctuation.

2. Project links

   A website and an X account are required, and a Telegram link is optional. They are packed into the coin's metadata link, which is stored on Solana with the coin, shown by wallets and explorers, and listed on its page.

3. An image, if you like

   Accepted formats are PNG, JPEG, WebP and GIF. The image is cropped to a square, stored, and named after a hash of the stored file. That hash rides in the coin's metadata link, which lets anyone compare the picture on the page with what was launched. Without an image, the coin gets art drawn from its address.

4. A first buy, if you like

   The launch transaction can buy some of the new coin for you before anyone else can. It has its own slippage setting, from 0.1 to 10 percent, and the form shows how far your buy moves the price.

5. Review, then sign

   The review sheet repeats each field and adds the creation fee (reading), the first buy and the full amount your wallet pays. The launch is simulated on Solana first, with the creation fee read again from the launchpad account, and only then does your wallet open. The coin's address is a fresh key generated in your browser, and it signs alongside your wallet.

6. Trading opens

   A moment later the coin exists: 1,000,000,000 of it, with 6 decimals, and an open market. You get links to the coin page and to the launch transaction on the explorer.

Buy and sell

Every coin page has a panel with Buy and Sell. It reads the curve straight from Solana and quotes with the program's own math, so trades work even while the indexer is catching up.

Slippage

Default slippage is 1 percent, and any value between 0.1 and 10 works. It sets the minimum you accept, and the program rejects a trade that would land below it. If the numbers move between review and signing, the panel asks you to review again.

Four steps per trade

A trade passes through Check, Wallet, Solana and Done. Right before your wallet opens, the app reads the curve and quotes again, then simulates the transaction to confirm that the curve is open, your balance covers it and the price is within your slippage setting.

Curve and pool

Each coin starts with its whole supply, 1,000,000,000, on a curve of its own. The program's formula raises the price with every buy and lowers it with every sale.

The curve is complete when it holds reading. Its liquidity then moves into a Meteora pool and stays locked there, and trading carries on in the pool.

How a launch is notarized

Think of a notarization as a signed statement of fact. It names the wallet, the coin, the Solana slot and time of the launch, and the name, ticker and links the coin started with. It is written into the memos of a Zcash transaction, so Zcash's proof of work fixes its date. A copy of the coin made tomorrow gets a notarization dated tomorrow.

1. Launched

   The coin and its curve go live in a single Solana transaction. Notarizing runs after that, so the launch never waits for it.

2. Signed

   Once Solana has finalized the launch, the signer signs the entry twice: with ed25519, the scheme behind every Solana key, and with Falcon-512, a post-quantum scheme.

3. Sent

   One shielded Zcash transaction carries three memos: a readable line that names the coin, then the signed entry split over two data memos.

4. Confirming

   Each Zcash confirmation adds one to the count on the coin page, which runs up to 10.

5. Notarized

   Once 10 confirmations are in, the viewing key decrypts the memos and each field is matched against the launch on Solana.

What a coin page can show

• Notarization pending: Solana is still finalizing the launch.
• Lined up for Zcash, then Broadcast to Zcash: the entry is on its way to Zcash.
• Confirming, 1 of 10 through 10 of 10: the Zcash confirmations counted since it went out.
• Notarized and checked: 10 confirmations in, opened and checked.

Notarization dates this coin on Zcash and names the wallet that launched it, signed.

Read entries in a Zcash wallet

The memos of a Zcash transaction are encrypted for the account that receives them. A viewing key reads them without any power to spend, and Notara publishes the viewing key of the account that receives every notarization. Add it to a Zcash wallet that supports viewing keys and each entry shows up as a memo that begins with the coin's name, mint address, slot and time.

The viewing key shows up here as soon as the first notarization is written.

Entries from this site go to the Zcash development network. The readable line is a convenience. The check that counts is the pair of signatures, which verify against the signer listed in the reference tables, and the open verifier runs exactly that test.

Check one yourself

A coin page links to the launch on a Solana explorer and, once the entry is sent, to its transaction on a Zcash explorer. That explorer shows the transaction but keeps the memos closed without the viewing key above. Compare the slot, time and transaction signature in the entry with the launch.

Fees

Notara takes two fees, both in SOL.

• Trade fee, reading. It comes off the SOL you spend on a buy and off the SOL you receive on a sale, and it is written into the launchpad account.
• Creation fee, reading. You pay it once, when you launch a coin.

The curve program collects both and pays them to Notara's treasury wallet, listed in the reference tables. Meteora keeps a share of each trade fee as its protocol fee.

Solana also charges a small amount to process each transaction, and the first time you hold a coin your wallet pays rent for that coin's token account.

Reference tables

Launchpad values are read from the launchpad account as the page loads and are marked as such. Everything else comes from the indexer.
