How notax works

Launching a coin costs a flat 0.5 SOL, sent to the notax treasury. That is the platform’s only revenue line.

On top of the fee, Solana itself charges rent for the three accounts a launch creates: the mint, the bonding curve, and the curve’s token vault. Together they come to under 0.01 SOL. Rent is a deposit held by the network, not a fee paid to notax.

Buys and sells have no fee term at all. The price comes from the reserves alone, and every lamport a buyer sends goes into the curve.

When you trade, the app builds the transaction with a notax sponsor wallet as the fee payer. Your wallet signs it, then the server co-signs and sends it. You never need SOL set aside for fees.

The sponsor only signs transactions that touch the notax program, the compute budget, and token account creation, and it never appears inside an instruction, so no program can move its SOL. If the sponsor is off, or your wallet can only sign-and-send, your wallet pays the normal network fee instead.

Every coin mints 1,000,000,000 tokens. 793,100,000 are sold on the curve; the rest is reserved to seed the DEX pool at graduation. The curve starts with 30 virtual SOL against 1,073,000,000 virtual tokens, which sets the opening price.

Each buy adds SOL to the reserves and removes tokens; each sell does the reverse. All rounding favors the curve, so a buy followed by a sell can never gain a lamport.

For the first five seconds after launch, each buy is capped at 1 SOL. That keeps bots from sweeping the opening price before people can get in.

With the default parameters, the curve sells out after about 85 SOL of buys. Trading on the curve stops. The raised SOL and the reserved tokens seed a Meteora DAMM v2 pool at the lowest fee the pool allows, and trading continues there.

Only the configured migration authority can release a graduated curve, and only once. Until it does, the curve holds the SOL.

Coins are Token-2022 mints with on-chain metadata and nothing else: no transfer-fee extension, no transfer hook, so the token itself can never carry a tax. The full supply is minted into the curve at launch, then the mint authority is revoked. Freeze authority is never set.

Pausing the launchpad stops new launches and buys. Sells always stay open, so holders can always exit.
