Introduction

Halo is a Solana launchpad that prices the first block instead of banning it, pays creators 0.5% of every trade, and uses another 0.5% to buy the coin back and burn it, so the volume stays with the people who made it.

Launchpads are under fire, and the complaints are fair. A few wallets take a huge slice of a new coin in the first block for a few SOL. Everyone else fights over what is left. The fees disappear into somebody's wallet.

The usual fixes make it worse. Cut creators off, and builders have no reason to launch with you. Ban duplicate tickers, and a good copy just picks another one while a real project that arrives a minute late gets blocked. Add more pairs, and one market splits into several thin ones.

Halo is built for launches where the crowd gets a real first block, and it gets there by pricing the first block instead of banning it. Taking 5% of a new coin in the first block costs 1.47 SOL on Pump's published curve and 3.65 SOL on Halo's. Taking 30% costs 11.64 SOL there and 27.92 SOL here. Creators keep 0.5% of every trade. Another 0.5% goes back into the coin itself, buying it back and burning it automatically. All of it runs on one SOL pair, so launching, trading and holding draw from the same volume instead of someone extracting it.

Each problem has one answer.

How the money moves

Each trade pays a flat 1.56% fee, and Halo's configuration splits what is left after Meteora's cut:

  • Creator, 0.5% of volume. Paid on chain and claimable from the creator's own wallet. See Creator fees.
  • The coin, 0.5% of volume. Spent automatically buying that same coin back and burning it, with nothing to claim and no schedule to wait for. See Buyback and burn.
  • Treasury, 0.25% of volume. Buys and burns the main coin the same way.

The first block is covered in First-block pricing, including the numbers and what the design does not stop.

What a launch looks like

  1. You connect a Solana wallet, fill in a name, symbol, image and description, and sign one transaction. Launching has no platform fee; you pay the network rent for the accounts that are created.
  2. The transaction creates the token (1 billion supply, 6 decimals, fixed supply, no mint authority) and its virtual pool on the shared Halo configuration. You can include a first buy in the same transaction.
  3. The coin appears on the board and anyone can buy and sell against the curve.
  4. When the curve has collected 120 SOL, the coin graduates: the SOL and 292 million tokens seed a real Meteora DAMM v2 pool, and the liquidity is permanently locked.
One transaction launches a coin. At 120 SOL raised it moves to a pool with locked liquidity.

Where to go next

Halo is built on Meteora's Dynamic Bonding Curve program and does not deploy its own smart contract. The buybacks and burns are run by Halo's job off chain, with every swap and burn public on chain, and are described honestly in Buyback and burn and Security.
