Mark Lamb, CEO of CoinFLEX | Bitcoin, flexUSD & How Interest-Bearing Stablecoins Are Changing DeFi | Bitcoin.com Interviews

Mark Lamb, CEO and co-founder of CoinFLEX, joins Dustin Plantholt on Bitcoin.com Interviews to discuss how Bitcoin and DeFi innovation are transforming stablecoins, yield generation, and the future of on-chain liquidity.

A veteran in the crypto space, Mark discovered Bitcoin in 2012, became one of the largest OTC market makers, and later founded Coinfloor, the UK’s first Bitcoin exchange. In 2018, he launched CoinFLEX, the first deliverable crypto futures exchange, and later introduced flexUSD — the only stablecoin that automatically pays interest. Today, CoinFLEX processes billions in repo volumes and manages over half a billion in yield-generating products like flexUSD and AMM+.
