With Cardano the impact of pool fees on rewards reduce as stake increases, up until the saturation point is reached. For these reasons a flat fee approach is sub-optimal, they reduce rewards when a pool is small and needs to grow and they offer no resistance to reward killing over-saturation as they get too big.

Why our fees are better than flat fees:

  • Encourages growth, no fees until pool exceeds 15% saturation
  • Low fee of 1% between 15 to 65% saturation
  • Gears pool towards optimal stake and therefore optimal rewards
  • Increased Saturation Protection as stake grows too large
  • No surprises

BIRD Pool Saturation Margin Fee Up to Stake
0 - 15% 0% 9.51M ₳
15% - 65% 1% 41.21M ₳
65% - 80% 2% 50.72M ₳
80% - 95% 3% 60.23M ₳
+ 95% 5%

Saturation Protection

Without a saturation mitigation strategy even a 0% pool is likely to be less profitable over the long term, the slower the pool recovers from over-saturation the more devastating the losses. Critically even the most active stakers are slow to react as they don't realize the drop in rewards until it hits their wallets 2 epochs later!

With Saturation Protection our pools automatically regulate stake via a progressive fee structure which ramps up in the final 5% of saturation. This brings back delegation towards an optimal stake preventing the pool from reaching over-saturation which massively impacts rewards.

  • Enables highly profitiable set and forget staking
  • Actively combats over-saturation - before it impacts rewards
  • Discourages new stakers when pool is under threat of saturation
  • Encourages active stakers to migrate before pool becomes saturated
