Make the Pool Admin redundant! Join our discord server to learn about Automated Friedger Pool and how to earn xBTC rewards.

Hi! I'm Friedger, join the Friedger Autonomous Self-service Trust (Fast) stacking pool using the Hiro stacking app (works with Hiro Wallet or Xverse Wallet).


I have been a contributor to Stacks since 2018, and am based out of Europe.

I worked on the Android SDK back in 2018. Since then, I have submitted many patches, test libraries and tools as they have become available. I have developed Stacks apps, have mined Stacks earlier in 2022, and even deployed the first user contract on mainnet.

I am inspired by all work that helps to bring back a user-owned internet. Fast Pool is another step towards this vision.

You can reach me on discord (friedger#0185) to provide feedback and ask questions.

As delegatee, I cannot make any APY promises about the payouts. It depends on how much the miners transfer. We do not know in advance, but you can view to get an idea and view for historical data.

This pool is run for the community, there are no fees.

Fast Pool (aka Friedger Pool)

The pool is now called Fast Pool. It is a SELF-SERVICE pool, the smart contract is the pool operator, only reward distribution is (still) trustfull.

The rewards are distributed as STX tokens to your address used for stacking (or the one registered in the payout hints smart contract.

The website gives you easy access to the pool features.

No need to enter a BTC address anywhere as rewards distribution is in STX.

Your STX token will lock immediately, you can increase the amount every cycle, you can revoke at any time and your STX tokens will unlock 1 day after the end of the cycle.

For Hiro Wallet Desktop users, you can use ‘SP21YTSM60CAY6D011EZVEVNKXVW8FVZE198XEFFP.pox-fast-pool-v2’ as pool address. (Yes, it is a contract). You need to use version 4.10 or later.

Do not send any tokens (STX or others) to the smart contract, instead follow the delegated stacking flow in your preferred wallet

Please do not stack less than 40 STX. Small payouts are hard to manage.

You or somebody else need to renew your delegation every cycle! You have 1 week to stop pooling, after that you can ask your friends or family to do renew for you, or setup an automated script.

You can check whether your address is part of a cycle at
