Marcus Tan

Marcus Tan is TheWeal's DeFi Editor, covering decentralised exchanges, lending, stablecoins, yield and the on-chain plumbing most readers never see. He has followed decentralised finance since 2018, through the first yield-farming wave, the stablecoin de-pegs, the bridge exploits and the slow institutional rediscovery of on-chain credit. Working from Hong Kong, Marcus reads contracts and dashboards as fluently as he reads price, and he treats total-value-locked, real yield and protocol revenue with the scepticism they deserve. His coverage is built on a habit of asking where a yield actually comes from — and saying so plainly when the answer is 'from the next person in'. Marcus believes the best DeFi journalism is a translation job: taking a mechanism that is genuinely complex and making it legible without making it sound safer than it is. He is candid about smart-contract and counterparty risk, and he expects TheWeal's explainers to leave readers more cautious and better informed, not more excitable.
