About Marta

Marta moved into iGaming from fintech in 2020, after several years auditing DeFi protocols and writing on-chain analytics. She holds a Master's in Computer Science from KTH Royal Institute of Technology in Stockholm and applies that background to the parts of crypto gambling that traditional reviewers tend to skim past.

Her reviews verify provably-fair implementations against published server seeds, benchmark deposit and withdrawal times across Bitcoin, Ethereum, Lightning Network, Tron and Solana, and document where KYC actually triggers on each operator - not what the marketing page claims. She has personally tested every crypto-first casino listed on GambleDude.

Marta covers crypto-native operators globally, with a particular focus on no-KYC and provably-fair sites.
