What our customers have to say.


«Zokyo has been amazing. One of our earliest supporters they are willing to work with you from the earliest stages and scale into the high demand areas as you grow. They are a fantastic partner and we’d recommend them to anyone.»

- Bryan Pellegrino, Co-Founder and CEO of LayerZero Labs

Zokyo has been an instrumental part of our product launch process. Their auditing team has shown to have a deep knowledge of both the technical details of Solidity code auditing as well as higher level expertise on DeFi concepts. They did a great job building tests, making suggested improvements, and ensuring the safety of our contracts. We look forward to working with them as we build new products.
