Just confirmed if it was centralized but its actually not. From the website "Legolas Exchange incorporates a decentralized ledger within its proprietary centralized platform in order to neutralize front-running and guarantee the unalterability, temporality, and transparency of the order book".
Decentralized ledger is the buzzword to say blockchain in this instance it's the exchange's bitcoin wallet, the exchange in itself is centralized.
I quote their website:
"Fully Decentralized Exchanges: An Unrealistic Solution
Transactions between different blockchains and fiat transactions are impossible on decentralized exchanges. This is a significant drawback to their use given that transactions within the same blockchain represent only 3% of all daily transactions.
Although some projects have been working on the cross-chain issue, a satisfactory solution has yet to emerge, and in any case their potential future expansion is limited to 25% market share."Their whitepaper's title is
"Legolas Exchange A DEMONSTRABLY FAIR, PREMIUM CENTRALIZED EXCHANGE USING DECENTRALIZED BLOCKCHAIN TECHNOLOGY"https://legolas.exchange/static/public/legolas-whitepaper.pdf?v=11
