New on-chain data has put a hard number on one of Cardano's most debated long-term questions: can network fees ever carry a meaningful share of staking rewards?
According to an analysis by blockchain data provider Bitquery, Cardano collected 3.3 million $ADA in transaction fees across 73 epochs between September 1, 2025 and September 1, 2026. Over the same period, the network distributed 493.7 million ADA in staking rewards. The result: fees accounted for roughly 0.67% of total reward payouts, or about one ADA in fees for every 150 ADA paid out to stakers.
The shortfall is not a bug in Cardano's design, at least not yet. Under the protocol's monetary policy, staking rewards are funded from two sources: transaction fees and a controlled release from the protocol reserve.Each epoch, 0.3% of the remaining reserve enters a virtual pot alongside collected fees. The treasury takes 20% of that pot, with the remainder distributed to stake pools based on performance. The reserve is deliberately structured to shrink over time.
The problem is that fees have not grown fast enough to offset declining reserve emissions. A snapshot of epoch 654 illustrates the scale of the challenge: 108,500 transactions generated just 33,855 ADA in fees across five days, equivalent to around 21,700 transactions per day and 0.251 transactions per second. Fees in that single epoch covered only 0.339% of the roughly 9.998 million ADA distributed in rewards.
Daily transaction volumes tell a similarly sobering story. Cardano averaged 90,294 transactions per day in 2022. From January through August 2026, that figure dropped to 24,869, a decline of more than 72%, according to Bitquery's count. Bots' share of transactions also rose from 11.5% in 2022 to 32.8% in 2026, with batchers forming the largest identified bot subgroup.
Cardano's original economic design anticipated this transition. As network usage increases and reserve emissions decrease, transaction fees are designed to become the primary yield source. That handoff has not yet materialised at the volumes required.
Planned protocol upgrades could expand the network's capacity. The Leios testnet went public, with the Musashi Dojo testnet launching on June 23, the first time Ouroboros Leios has run on a live test network.By introducing endorser blocks and committee-based validation, Leios aims to safely scale Cardano's throughput capacity by 10x to 65x through a phased rollout. However, Leios can add capacity, but Cardano still needs enough paying demand to close a roughly 150-fold gap.
Organic demand from decentralised applications, DeFi, and everyday users will ultimately determine whether fee income can close the shortfall. For now, the numbers are stark: 3.3 million ADA in fees against 493.7 million ADA in rewards. Cardano's epoch 655 data showed roughly 6.1 billion ADA left in reserves, equal to 13.62% of the network's 45 billion ADA maximum supply. The reserve continues to shrink each epoch. Growing on-chain activity is not just a metric worth watching. It is increasingly central to Cardano's economic future.
