Explore the complete Cardano ADA supply distribution for epoch 634, which began on 2026-05-29 and is still ongoing.
This interactive insight helps you understand how the total ADA supply is allocated across key categories — from circulating supply and reserves to staking rewards and the treasury.
At the close of each 5-day epoch, the Ouroboros protocol performs supply and reward calculations across all participating nodes. The resulting transfers distribute staking rewards and allocate a portion to the Cardano treasury, supporting ongoing development and ecosystem growth.

Epoch 634 facts:
Q: How did the values change compared to the previous Epoch?
A: At the start of epoch 634, the Cardano Ouroboros protocol distributed the staking rewards for epoch 632 and transaction fees collected in epoch 633. This transferred 10,441,320 ada from the reserves to the active supply, equivalent to a 0.16% decrease in reserves and a 0.03% increase in active supply.
Q: How much ada was added to the treasury?
A: In epoch 634, rewards and fees contributed 3,800,254 ada — 36.40% of the overall staking rewards — to the treasury. However, withdrawals of 131,510,090 ada from this epoch outweighed this amount, resulting in a net decrease of 127,709,836 ada (-8.42%) compared to the previous epoch.
Q: How many fees were collected and distributed?
A: In the currently running epoch, 45,536 ada in transaction fees have been paid so far. 659,035 ada from epoch 633 was distributed as rewards and treasury extension. These fees came from 134,039 transactions, averaging 0.33 ada per transaction, and accounted for 0.44% of the total rewards distributed
Q: Were there withdrawals from the treasury in epoch 634?
A: There were 6 treasury withdrawals totaling 131,510,090 ada.

Q: Where can I learn more about the Cardano Mainnet reward calculation?
The reward calculation is based on the ledger specification. Further information can be found in the Cardano Blueprint documentation. There is an independent Java implementation with many explanations, as well as a training course from Cardano Academy on calculating staking rewards.
