Part 1 of the Catalyst Off-Chain Impact Series

When Cardano needed a faster, simpler way to build and submit smart contract transactions, mLabs delivered the Cardano Transaction Library (CTL), a modular SDK that’s now powering DeFi, GameFi, and DAO apps across the network.

This in-depth case study goes beyond on-chain metrics to reveal how CTL became essential ecosystem infrastructure: how phased funding shaped its growth, how modular design accelerated adoption, and how open-source stewardship secured its long-term impact.

As the first in a 12-part series funded under Project Catalyst grant #1300147, it offers rare, data-driven insight into how targeted infrastructure investments can transform developer experience, and set the standard for funding success in decentralized ecosystems.
