Cardano’s gap between transaction fee revenue and staking reward outlays has become a central structural concern, according to full-chain data from Bitquery. Over 73 five-day epochs ending Sept. 1, 2026, the network generated 3.3 million ADA in transaction fees while distributing 493.7 million ADA in staking rewards. Fees covered about 0.668% of rewards, leaving the reward total roughly 149.6 times larger than fee revenue.
The official epoch 654 snapshot showed a similar pattern on a shorter window: 108,500 transactions and 33,855 ADA in fees over five days, against about 9.998 million ADA in distributed rewards. Cardano’s epoch 655 data placed remaining reserves at 6,126,859,027 ADA, equal to 13.62% of the 45 billion ADA maximum supply.
Network usage has weakened markedly. Cardano averaged 90,294 daily transactions in 2022, but only 24,869 daily transactions from January through August 2026, a decline of 72.46%. Bot activity also became more prominent: the share of transactions classified as bots rose from 11.5% in 2022 to 32.8% in 2026. The share of circulating ADA staked fell from 75.6% at the end of 2022 to 58.3% in the final studied epoch.
Under Cardano’s monetary policy, transaction fees and 0.3% of the remaining reserve enter a virtual pot each epoch. The treasury receives 20%, while the rest is available for staking rewards, subject to pool performance. The reserve is designed to shrink exponentially with a documented half-life of roughly four to five years, though no fixed exhaustion date is set. As emissions decline, nominal reward payouts can fall, which mechanically reduces the fee revenue needed to match them, but the network would still require substantial real fee-generating activity.
Scaling the 2026 average of 24,869 daily transactions by the 149.6 reward-to-fee ratio produces a simplified gross breakeven scenario of about 3.72 million transactions per day, or roughly 43.1 transactions per second, before the treasury allocation. That aligns with an earlier CryptoSlate model placing the central estimate near 45 TPS after the treasury cut.
Cardano’s planned Leios upgrade may address the capacity side. In an August public testnet update, Cardano reported roughly sixfold Leios performance using synthetic traffic, and a later test environment demonstration showed about 1,000 TPS. The proposed CIP-164 specification models sustained capacity above the simplified 43.1 TPS scenario. Intersect’s Dijkstra planning document targets code completion in the fourth quarter of 2026, excluding Preview and pre-production testing and governance time; the mainnet hard-fork date remains undetermined. Still, test results show capacity, not demand. Multiplying fee revenue by roughly 150 times will depend on applications and users producing sustained paid activity.
