What is Azuro?
Azuro is a decentralized protocol for prediction markets that supplies odds, liquidity and settlement to betting apps on EVM chains. Users do not bet on Azuro directly; they use frontends such as Bookmaker.xyz that connect to its contracts.
Azuro pools liquidity in a single LiquidityTree that backs every market across connected apps. Data providers post initial odds, and a virtual AMM adjusts them as bets arrive, so profit-seeking bettors push prices toward fair value.
Markets cover sports and other events. Version 3, released in May 2025, added cashouts and freebets, and the toolkit and SDK have had regular releases through October 2026. Production deployments are listed for Polygon, Gnosis, Base and Chiliz.
Bets are placed as transactions to Azuro contracts and winnings are claimed from the contract, so funds normally stay in the user's wallet. Apps are separate entities from AzuroDAO, and the docs warn users to check the frontend they use.
V3 contracts were audited by Hexens and Pessimistic in March 2025, with a PayMaster audit in April 2025. Results are settled by data providers under a published rules and settlement policy, with AzuroDAO governance and the AZUR token.
Good fit for
- Crypto users wanting on-chain sports betting with self-custody
- Developers building betting or prediction apps
Not ideal for
- Traders looking for order-book binary markets like Polymarket
- Users in jurisdictions where online betting is prohibited

Azuro fees
Azuro does not charge bettors a separate fee. Each market (condition) is created with a profit margin, and the protocol lowers the quoted odds by an outcome spread derived from that margin. The size of the margin is set per condition and is not published as a single number.
Bettors pay network gas on the chain they use; a PayMaster can sponsor gas on some apps. Liquidity providers earn from bettors' net losses and frontends receive a share of protocol revenue, so the effective cost to a bettor is the margin in the odds.
