Cardano proposal seeks to cut minimum pool cost from 170 ADA to 75 ADA

  • Cardano submitted a standalone proposal to reduce the minimum pool cost to 75 ADA.
  • 170 ADA is the current mainnet minimum, while voting ends in epoch 661 on Oct. 11.
  • The earlier bundled action expired after insufficient stake pool operator support.

Cardano has submitted a standalone governance proposal to reduce the minimum pool cost, or minPoolCost, from 170 ADA to 75 ADA without changing Plutus memory limits. Unlike the earlier bundled action, the proposal requires approval from DReps (delegated representatives) and the Constitutional Committee but not stake pool operators. The earlier action expired on Sept. 1 after DRep support reached 68.6% against a 67% threshold and five of seven committee members voted yes, while SPO support reached only 34.5% of counted stake against a required 51%. In a cached DRepTalk tally checked Sept. 23, the new proposal had 11.7% of counted DRep stake in favor and two of seven committee members voting yes, or 28.6%, against a 66.7% threshold. Voting ends in epoch 661 on Oct. 11. The proposed floor would not force lower fees: operators could declare 75 ADA, continue charging 170 ADA, or retain a higher amount. A pool's fixed cost is deducted from gross rewards before its margin and before the remaining rewards are distributed by stake, meaning smaller pools and delegators could benefit when operators actually lower their charges. The economic effect remains uncertain because an Input Output Research study found that 340 ADA remained the most common declared fee after the previous minimum was cut from 340 ADA to 170 ADA in October 2023. The proposal's author presents the lower floor as an interim step toward broader fee reform, but its success will depend on operator behavior, future delegation and pool sustainability.
