Cosmos ATOM Staking

How ATOM staking works on Cosmos Hub via Yield.xyz

Cosmos Hub ATOM staking with validator selection, 21-day unbonding, and reward claiming via the unified Yield.xyz API.

---

What this yield is

• Asset: ATOM (native Cosmos Hub token)
• Mechanism: Delegate ATOM to validators to secure the network
• Rewards: Staking rewards accrue per block; must be claimed explicitly
• Unbonding: 21-day unbonding period; funds do not earn during unbonding

---

Required inputs

Argument	Required	Description
amount	Yes	Amount of ATOM to stake
validatorAddress	Yes	Validator operator address (cosmosvaloper…)

Fetch available validators from the validators endpoint.

Actions & lifecycle

Enter

• Call /actions/enter with amount and validatorAddress
• Single delegation transaction returned
• Sign with Cosmos-compatible signer (cosmjs, Keplr, etc.)
• Position becomes active after block confirmation
• Rewards begin accruing immediately

Exit

• Call /actions/exit with amount to undelegate
• Initiates 21-day unbonding period
• Funds do not earn rewards during unbonding
• Cannot be cancelled once initiated
• After 21 days, funds become claimable

Manage

• Claim rewards: Withdraw accrued staking rewards
• Restake: Compound rewards back into delegation
• Redelegate: Move stake to different validator (no unbonding)
• Check pendingActions in balances for available operations

2. Get validators

   List available validators with performance metrics.

3. Request enter action

   Call enter with amount and chosen validator.

4. Sign & submit

   Sign the Cosmos transaction and broadcast.

5. Track balances

Operational notes

21-day unbonding

Unbonding cannot be cancelled. Plan exit timing accordingly. During unbonding, funds are not earning rewards and are not liquid.

Slashing risk

Delegated ATOM is subject to slashing if the validator misbehaves. Diversify across validators to reduce exposure.

Reward claiming

Rewards accumulate but must be claimed explicitly. Use the manage action with claim-rewards type. Rewards can also be auto-restaked.

Redelegation

Cosmos allows instant redelegation to a new validator without unbonding. However, you cannot redelegate again for 21 days from the destination validator.

Shield recommendation

For institutional custody flows, validate transactions with Shield before signing.

Considerations

When a user delegates additional tokens to a validator they already have a staked position with, any earned rewards are automatically claimed and added to the user’s available balance. Similarly, when a user partially or fully unstakes their position, the unclaimed rewards are also automatically claimed.

In some cases, there can be a precision loss issue in the Cosmos SDK during unbonding, specifically when converting from validator shares back to tokens. The loss due to this issue can be 1 uatom.

Osmosis

OSMO staking (14-day unbonding)
