# What is glgl

Launch coins backed by the world's fastest resolving prediction markets. 20 and 60 second up/down rounds on Solana, powered by OddsFi.

glgl is a network for very short prediction markets on Solana. Pick Higher or Lower on the price of Bitcoin, wait 20 or 60 seconds, and the winning side splits the pool, with no house on the other side. The name means good luck, good luck.

Anyone can create their own market, with its own look and its own coin. Every market runs on the same rounds and the same liquidity, which OddsFi provides.

**Every round has two fees, both 2.5%:** one when you enter, and one on your payout if you win. The entry fee buys back ODDS and the market's coin. The fee on winnings funds the market maker's give-back, which aims to return it to players through the pools over many rounds. Neither is kept as platform revenue.
