What is Cosmos
Cosmos is an open ecosystem designed to connect multiple independent blockchains. It is often referred to as the “Internet of Blockchains.” Its architecture is based on Hubs and Zones. Hubs act as cross-chain centers, while Zones are independent blockchains that can operate autonomously. These blockchains communicate and exchange assets and data through Cosmos’ Inter-Blockchain Communication Protocol (IBC), breaking down the isolation between individual chains.
Cosmos uses the high-performance, secure, and scalable Tendermint consensus mechanism along with its modular SDK toolkit, enabling developers to easily build new chains and quickly join the ecosystem with flexibility, security, and interoperability.
What is Cosmos (ATOM) Staking
Cosmos adopts a Proof of Stake (PoS) mechanism, where validators verify and produce blocks. Staking ATOM means locking your ATOM tokens on the network and delegating your voting power to validators who maintain network consensus. In return, you earn block rewards while helping to strengthen the security of the entire Cosmos network.
Staked ATOM remains locked on the blockchain. When you choose to unstake, there is a 21-day unbonding period during which your ATOM cannot be transferred or traded.

Instructions
Staking Guidelines
-
Amount-based staking
In the CoolWallet ATOM staking mechanism, rewards are calculated based on the amount of ATOM staked. The more you stake, the higher your proportional reward.
-
Participation by Staking Address
If you already have an existing ATOM stake and use the same address to add more, any unclaimed rewards will be automatically claimed and newly staked ATOM will be combined with your existing stake and accrue rewards together.
-
Rewards automatically distributed as staking status changes
When the staking status changes (such as adding more stake or initiating an unstake), any unclaimed rewards will be automatically claimed and sent to your wallet address.
-
Unstaking
After initiating an unstake, there is an unbonding period of approximately 21 days. During this time, your staked ATOM cannot be transferred and will no longer accumulate rewards. Once the unbonding period ends, your staked ATOM and any unclaimed rewards will be automatically returned to your wallet address.
How to Start Staking
Step 1. Open the CoolWallet App → Wallet → Earn → ATOM to access the ATOM Manage Stakes page.

Step 2. Tap Stake, confirm your Cosmos address and chosen validator, then tap Continue to proceed.

Step 3. Review the transaction details carefully, then verify the transaction.
(CoolWallet Pro or CoolWallet Go users will need to have their cold wallet card ready to sign)

Once verification is complete, your ATOM will be successfully staked and staking rewards will start accumulating.

How to Check Staking Status
Once staking is successful and rewards begin to accumulate, you can view your accumulated rewards under the Earn tab on the Wallet page.

How to Claim Staking Rewards
Step 1. On the Manage Stakes page, tap Claim Rewards and select the wallet address to receive rewards.

Step 2. Review the transaction details, then verify it with your CoolWallet Pro or CoolWallet Go to sign.

Step 3. Once successful, your accumulated reward balance will reset to nearly zero, and the claimed ATOM rewards will be directly sent to your wallet address.

How to Unstake
Step 1. On the Manage Stakes page, tap Request Unstaking, then select the wallet address you want to remove from delegation.

Step 2. Review the unstaking transaction details carefully, then verify the transaction. (CoolWallet Pro or CoolWallet Go users will need to have their cold wallet card ready to sign).

Step 3. After successful submission, the 21-day unbonding period will begin. During this time, your staked ATOM cannot be moved and will stop generating rewards.
After the period ends, your principal ATOM and any pending rewards will automatically be returned to your wallet address.

FAQs
Q1. Can I transfer my ATOM while staking?
No. Staked ATOM is locked and cannot be transferred, traded, or used. However, any unstaked ATOM in your wallet remains fully transferable.
Q1. What is the minimum amount required to stake ATOM?
The Cosmos network does not enforce a minimum staking amount, but you must keep enough ATOM to cover on-chain transaction fees. It is recommended to leave a small balance in your wallet for future operations.
Q3. Can I unstake ATOM anytime?
Yes. You can initiate an unstake at any time, but you must wait through a 21-day unbonding period before your ATOM becomes available again. During this period, your staked ATOM cannot be moved and will stop generating rewards. Afterward, the tokens will automatically return to your wallet.
Q4. When are staking rewards distributed?
ATOM staking rewards accumulate continuously to your delegation address and can be claimed anytime through the CoolWallet App.
If your staking status changes (such as adding or removing stake), any unclaimed rewards will be automatically sent to your wallet address.
Q5. How are ATOM staking rewards calculated?
The validator takes a portion of the total reward and the rest is distributed to the staker as an incentive in proportion to the delegated amount.
The reward depends on the network conditions, in particular, the fixed supply in the network, transaction fees, block times, and also on the performance of the validator’s earnings and other important factors.
Q6. Which validator is currently available?
When staking ATOM on CoolWallet, the current validator partner is Everstake, a well-known professional validator service provider recognized for its stable and reliable operation.
Q7. Why does the unclaimed reward suddenly become "0" ?
Status change (redelegate, request to unstake) will trigger an auto claim for any unclaimed reward, which will be sent to your address directly.
Q8. Are there any risks when staking ATOM?
According to the operating protocol of Cosmos, if the validator is punished by the Cosmos network due to misbehaving, part of your locked ATOM asset will be taken as a penalty.
