The Cosmos Hub is a proof-of-stake blockchain secured by validators who lock up (bond) ATOM. Most holders participate by delegating their ATOM to one or more validators — the tokens never leave your wallet's control, but they back the validator's weight in consensus and earn a share of the rewards.

Staking rewards on the Cosmos Hub come from two sources:

• Newly issued ATOM — the protocol mints new tokens each block and distributes them to bonded stakers. Issuance is dynamic: it adjusts with the share of ATOM staked, and governance has tightened the inflation bounds over time.
• Transaction fees — a share of the fees paid on the Hub is distributed to validators and their delegators.

Validators charge a commission on the rewards they generate for delegators — commonly around 5%, but each validator sets its own rate. Your net reward rate is the network rate minus this commission, which is why two delegators staking the same amount can earn different yields.

Rewards accrue every block (roughly six seconds) but are not added to your stake automatically. You claim them in your wallet and can restake them to compound. If you want to switch validators, redelegation takes effect immediately — no unbonding required — though each stake can only be redelegated once per unbonding period.

There are three main ways to put ATOM to work, each with trade-offs:

Native delegation — Delegate from a self-custody wallet such as Keplr or Leap. There is no minimum amount, you keep custody of your keys, and you earn the full network rate minus only the validator's commission. The trade-off is the 21-day unbonding period when you want to exit.

Exchange staking — Centralized exchanges stake on your behalf. It is the easiest setup and often offers flexible redemption, but the exchange holds your keys and takes a cut of the rewards, so net yields are usually lower than native delegation.

Liquid staking — Protocols such as Stride issue a token (e.g., stATOM) that represents your staked position and accrues staking value. You stay liquid and can use the token in DeFi, in exchange for protocol fees and added smart contract risk.

The calculator above uses the live Cosmos reward rate, so you can compare what a given amount of ATOM earns across time horizons and providers with their actual fees factored in.

Staking ATOM is a core, protocol-level yield strategy, but it is not risk-free:

• Slashing — If your validator double-signs, a portion of its stake (including delegations) is slashed — 5% on the Cosmos Hub — and the validator is permanently removed. Extended downtime triggers a smaller 0.01% slash plus temporary jailing. Choosing established, well-run validators keeps this risk low.
• Unbonding lockup — Undelegating takes 21 days, during which your ATOM earns no rewards and cannot be transferred or sold. Liquid staking tokens avoid the wait but add their own protocol risk.
• Validator quality — Commission rates, uptime, and governance participation vary. A high commission or poor uptime directly reduces your net yield.
• Price volatility — Rewards are paid in ATOM, so your realized return in fiat terms depends on the token price as well as the reward rate.
• Tax treatment — Staking rewards are typically taxable as income when received. Consult a local tax professional.
