These pages explain Koine in plain words for someone who has never used it. Each section ends with a "Source:" line naming the code it describes, so you can check it.

## What is Koine?

Koine is a website for launching and trading new coins on Solana. Anyone can launch a coin, and each coin starts with a presale where everyone pays the same price. Trading opens about an hour after the presale ends, with a fee that starts at 99% and falls to 1% in about 100 seconds, so bots that rush in first pay most of what they spend as fees. After that, part of every trading fee goes to the coin's creator while they keep looking after it, part buys the coin back and burns it, and part goes to Koine. You do all of this from a Koine wallet that Koine makes for you when you sign in.

Koine is preparing to launch on Solana mainnet and isn't open yet. Its code has not been audited.
