It’s not big news, but Cardano generated 3.3 million ADA in transaction fees against 493.7 million ADA in staking rewards across the 73 five-day epochs ending Sept. 1, 2026. Fees covered about 0.668% of rewards, leaving the reward pool roughly 149.6 times larger than fee revenue.
That gap widened as usage thinned out. Average daily transactions fell 72.46%, from 90,294 in 2022 to 24,869 between January and August 2026, turning the fee-versus-reward math into Cardano’s most pressing structural question heading into its next scaling upgrade.
Cardano’s Reward Model Faces a Growing Fee Revenue Gap
Cardano (@Cardano) collected 3.3 million cardano:native in transaction fees across 73 epochs from Sept. 1 2025 to Sept 1, 2026, according to Bitquery.

If we counted transactions from Cardano’s first block and grouped the comparison into 73 five-day epochs running Sept. 1, 2025, through Sept. 1, 2026. The official epoch 654 snapshot recorded 108,500 transactions and 33,855 ADA in fees over five days, against 9.998 million ADA in distributed rewards.
Cardano’s reserves stood at 6,126,859,027 ADA in epoch 655, equal to 13.62% of the 45 billion ADA maximum supply.

Why Reserve Emissions Still Do the Heavy Lifting?
Cardano (ADA)24h7d30d1yAll time
Under Cardano’s monetary policy, transaction fees and 0.3% of the remaining reserve flow into a virtual pot every epoch. The treasury takes 20% of that pot, and the rest is available for staking rewards, subject to pool performance.
The reserve is engineered to decay, with documentation citing a half-life of roughly four to five years and no fixed exhaustion date. As emissions shrink, nominal reward payouts can fall too, which mechanically narrows the fee-coverage gap without a single extra transaction being processed.
Current minimum fees combine a fixed component with a size-based charge, and protocol governance can still adjust those parameters, but closing the gap on a durable basis still depends on real fee-generating activity rather than a shrinking denominator alone.

Cardano News: Leios Solves Capacity, Not Demand
Cardano reported a sixfold increase in Leios performance in an August public testnet update using synthetic traffic. It is a capacity result, not evidence that mainnet users will generate enough activity to multiply fee revenue anywhere near 150-fold. Linear Leios is designed for throughput above the simplified 43.1 TPS scenario, giving the network a plausible technical path to process far more volume than it does today.
Ouroboros Leios is steadily progressing towards mainnet.
This week, the team demonstrated ~1,000 TPS in a test environment.
The mainnet-ready version is expected to be ready in November.
If all goes well, we could see Leios live on Cardano mainnet this year.

That gap between raw throughput and paying demand is not unique to Cardano. Solana’s Transaction v1 upgrade tripled data capacity on a chain that already runs higher fee volumes meaningfully, underscoring that added capacity only converts into network income when applications and users show up to spend it.
Until applications and users generate enough paid transactions to meaningfully close the 149.6-fold gap, Cardano’s staking yields remain a function of reserve depletion rather than organic network income, a distinction that matters for anyone pricing ADA on protocol fundamentals rather than nominal APY.
