  • Alonzo Blue Cardano testnet operators (one of the first ten operators chosen by IOG)
  • SundaeSwap ISO operators (one of 38 operators voted for by the Cardano community)
  • Recovering lost wallet funds and rewards
  • Educational blog posts
  • NFT creators (AdaCards, Project Cosmos, Space Pirates)
  • Developed a high-performance NFT sales and distribution platform on Cardano
  • Cardano-Tools Python package
  • Original Cardano incentivized testnet (ITN) stake pool operators

Low Fees


Viper Stake Pool has a very low fee per block. This fee structure distributes over 96% of the block rewards each epoch to our delegators.

High Reliability


We operate Viper Stake Pool on high-reliability cloud servers for guaranteed hardware performance and security. Multiple failover nodes are maintained and monitored by custom software to ensure 100% uptime.

Open Communication


Join our Discord server or Telegram channel and follow us on Twitter to receive pool announcements and to ask us questions! We look forward to hearing from you!

Global Connectivity


  • Our VIPER and ADDER block producer nodes are firewalled from the outside world to prevent denial of service attacks and malicious activity.
  • We operate 4 relays with distributed connectivity to peers in the United States, Europe, Asia, and Oceania for optimal blockchain synchronization.
  • Our nodes are connected via a redundant ring topology to ensure we stay connected to the global network even if a node goes down.

Remember: Real stake pools will never charge you for staking, and do not have access to your ADA! Pools collect a fee by taxing the block rewards before distributing it to the delegators.
