In this episode, I speak with Ben Hart, Chase, and Luke from MLabs about Pisa – their smart contract implementation of Babel fees on Cardano. Pisa allows users to pay for transaction fees, minimum ADA, and collateral using native tokens instead of ADA. The smart contract handles real-time token swaps behind the scenes and returns a ready-to-submit transaction. No changes to the Cardano ledger are required. SPOs are involved as normal, and there’s no batching – just seamless UX. Developers can integrate Pisa with a few lines of code via HTTP API or an upcoming NPM package. Topics include:

• What Babel fees are
• How Pisa improves the user experience
• Differences from other solutions like Aquarium
• Developer integration and the planned CIP
• Launch timelines and supported tokens

Pisa launches within 60 days and is set to improve onboarding for wallets, DeFi apps, and games across Cardano.
