First-block pricing
Grabbing a big share of a new coin in the first block costs a lot more on Halo, and the first moments carry a launch tax. Anyone can still buy in the first block.

Pump uses its published virtual reserves. Anyone can still buy in the first block, it costs more, and every buy is visible on chain.
Launch tax
A new coin's trading fee starts at 50% in its first block, is about 34% in the next, about 18% after that, and is the normal 1.56% in under a second. Everyone who buys in that moment pays it, including the creator's own first buy in the launch transaction. In the first block that is about double the Halo price in the table, and a patient buyer only has to wait under a second, so the tax targets block 0 and the first moments. The schedule is counted in slots, so its length follows the network's slot time.
The launch tax is split like every other fee: 32% goes to the creator, about 32% buys that coin back and burns it, 16% goes to the treasury and 20% to Meteora.
Why it costs more
Halo's curve starts at about 70 SOL of market cap, where Pump's starts at about 28. Both curves graduate at the same price, so early supply is priced higher on Halo and its price climbs less afterwards. See the curves side by side in Halo vs Pump in pictures.
Limits
A buyer can still take a large share of supply in the first block. It costs more. Meteora's program has no vesting or cap for tokens bought on the curve, so a creator's first buy pays the tax and has no other limit.
- The fee follows time since launch. It depends on how long ago the coin launched and ignores how much you buy, so a buy split across wallets pays the same fee. A size-based fee would hit honest buyers and can be avoided by splitting the buy.
- Every coin accepts any ticker. Anyone can buy in the first block at its price. A ticker rule is avoided by choosing another ticker and can block a real project. See Why Halo has one market.
- Launching is free. There is no deploy fee.
- Several wallets pay the same total. The curve prices supply for every wallet alike.
- A creator can buy their own coin. Their first buy is public and pays the same curve price.
- Selling works as usual. Check the holders list on the coin page.
