Market Rules & Terms

evently is a fully on-chain prediction market protocol on MegaETH. Markets use LMSR pricing. By creating or trading, you agree to these rules. All outcomes are settled by smart contract — evently is not liable for individual results.

1. Collateral & Market Creation

1.1
Collateral — Any user creating a market must lock 50 USDm as collateral. Admin-created markets are exempt.
1.2
Return — Your 50 USDm is returned in full upon honest resolution accepted without dispute.
1.3
Slashing — If a dispute succeeds, your 50 USDm collateral is sent to the treasury. Repeated violations may result in permanent blacklisting.
1.4
Dispute window — A dispute window follows each resolution. During this period, any bettor may contest the result. The admin has final authority.
1.5
LMSR pricing — Markets use a Logarithmic Market Scoring Rule (LMSR) with a liquidity parameter b=200 USDm. Prices automatically adjust with each trade based on the outstanding shares.

2. Fees & Revenue

2.1
Total fee — A 2.5% fee applies on every trade (not at resolution). It is split between three recipients.
2.2
Fee breakdown — 1% goes to the market creator · 1% goes to the evently treasury · 0.5% goes to the resolver pool.
2.3
Creator fee — As a market creator you earn 1% of all trade volume routed through your market. Admin-created markets redirect this 1% to the treasury.
2.4
Cancelled markets — No fees on cancelled markets — all positions are refunded in full.
2.5
Creator revenue — On 10,000 USDm of trade volume in your market, you earn 100 USDm in creator fees (1%).

LMSR mechanics — You buy outcome shares using USDm. Shares in the winning outcome are redeemable 1:1 for USDm at resolution (minus protocol fees).
3.2
Betting deadline — No trades can be placed after the betting deadline. The creator sets this at market creation.

Who can dispute — Any bettor on a resolved market may raise a dispute within the dispute window.
5.2
Admin authority — The evently admin settles disputes on-chain. Admin decisions are final.
