What our customers say
Grant Cermak, CEO
“Credmark's platform allows us to develop DeFi risk models faster than we ever could before. The integration of curated data sets, Python, and a library of pre-built data structures and models are an incredible springboard.”
Daniel Tse, CTO
“We started using Credmark's Token API and then needed some custom portfolio calculations. Credmark was able to build and deploy those in days. Thanks to their DeFi API we were able to immediately integrate that new data into our app.”
Exa, CTO
“Credmark enables us to easily write our own models, query historical data sets via APIs using an open source framework. This means we can focus on product iteration instead of building our own web3 data stack, or creating custom integrations to wrangle data.”
Cwalk, Founder
“Our deal with REDACTED was only made possible with Credmark’s DeFi API and the Credmark Model Framework. With the platforms, lenders can know the facility is backed by verifiable on-chain data.”
