The people behind every byline
Three editors, each on a beat. Every story, guide and rating on OBOL names the person who wrote it, and links here.
Dario Fenn
DeFi & Markets Lead · DeFi protocols, yield, market structure and on-chain data
Dario Fenn leads OBOL's coverage of decentralised finance and market structure. His beat runs from the mechanics of automated market makers and lending protocols through to how a trade actually fills — order book depth, funding rates, and the difference between an advertised yield and the one a position returns after fees, gas and impermanent loss.

Nadia Okoro
Policy & Consumer Editor · Regulation, tax, stablecoins and the products retail users hold
Nadia Okoro covers the rules and the products where they land. Her beat spans regulation and tax on one side — MiCA, the US framework for payment stablecoins, information reporting, the travel rule — and on the other the consumer-facing services those rules reshape: exchanges, stablecoins, cards and custody arrangements.

Selin Aydin
Security Editor · Crypto security, custody, exploits and smart-contract risk
Selin Aydin runs OBOL's security desk, covering everything from the first drained wallet through to the post-mortem nobody wants to publish. She previously worked in smart-contract auditing, reviewing code for bugs before they became headlines, and now applies the same forensic patience to reconstructing incidents after the fact: where the exploit entered, what the audit missed, and who is quietly exposed next.
