Low Fees

Our pool has a fixed fee of 25 ADA plus a 2% variable fee. This low fee structure distributes ~98% of the block rewards each epoch to our delegators, e.g., if the pool produces 10 blocks in an epoch, the effective tax rate is ~2.25%.

High Reliability

We operate VIPER stake pool on Amazon Web Service (AWS) cloud servers for guaranteed hardware performance and security. Multiple failover nodes are maintained and monitored by custom software to ensure reliability.

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. Read more about how pools take their payments here.

Pool Operator

Hello, I've been a part of the Cardano community since early 2018, when I purchased some of my first ADA at over 40 cents! Ever since learning about the project, I've wanted to run a stake pool and help decentralize what I believe to be the best cryptocurrency project in the world. My background is electrical engineering, in which I have a Ph.D. from Georgia Tech. Through my work on high-performance electromagnetic simulations, I developed my Linux sysadmin skills. Thank you for considering the VIPER stake pool! - Dylan
