Cardano staking: APY, no lock-up, and where the rewards come from

Staking Cardano pays a low single-digit return, calculated per epoch as described by cardano.org, for delegating ADA to a stake pool. It is the most forgiving model among major chains: no lock-up, and the ADA never leaves your wallet. The trade-off is the lowest headline rate of the large proof-of-stake networks.

How staking works on Cardano

Cardano’s Ouroboros protocol elects stake pools to produce blocks in proportion to the stake delegated to them. Delegation is a certificate posted from your wallet; the ADA itself stays spendable at all times. Rewards are calculated per 5-day epoch and compound automatically once they start arriving (first rewards take ~15–20 days after initial delegation).

Where the yield comes from

Rewards blend transaction fees with reserve emissions: each epoch a fixed fraction of the not-yet-circulating portion of ADA’s 45 billion max supply is paid out. Because the reserve only shrinks, the reward rate declines gently over the years, a fixed-supply variant of inflation funding. Pool performance and the saturation cap (which stops rewards growing past a per- pool stake limit) decide what an individual delegator actually receives.

Unstaking and lock-ups

There is nothing to unstake. Moving or spending delegated ADA simply reduces the live stake; the only outlay is a ~2 ADA stake-key deposit, which is returned when you deregister the key. This makes Cardano the reference point for “liquid by default” staking.

What can go wrong

• Pool selection. An oversaturated, badly configured or offline pool earns you less; the loss is opportunity cost, never principal.
• Declining rate. Reserve depletion means the current rate is the high end of what future years will pay, all else equal.
• Market risk. As everywhere: the yield is denominated in an asset whose price moves far more than the yield itself.

Cardano staking vs THORChain bonding

Cardano offers near-zero protocol risk at a low rate funded by reserves; THORChain bonding offers a historically much higher rate funded by swap fees, in exchange for whitelist entry, churn-timed exits and slash exposure. If you hold both assets, they answer different questions. The comparison is at THORChain vs Cardano staking, and the THORChain side at THORChain bonding.
