TESTIMONIAL
Trusted by institutional clients and proven in real-world deployments.
We had to use different APIs for each blockchain, which took a lot of time and was pretty inefficient previously. But Nodit brought everything into a single API, and that made our operations much simpler and more efficient.
Upbit
After adopting Lambda256s node services, operating and managing exchange deposits and withdrawals became far more efficient.
Coinone
Obtaining large scale transaction data from L2 ecosystems had previously been slow and challenging. By leveraging Nodits high performance Web3 APIs, we can now analyze data in real time, greatly improving both research speed and efficiency.
Radius
Operating our own node infrastructure on emerging blockchains like Aptos was not only costly and difficult to maintain, but also frequently caused performance issues. Nodits Aptos node and data APIs, intuitive console, and responsive technical support have allowed us to focus on delivering a stable, high performance DeFi trading experience without infrastructure concerns.
