Eternl is a self-custody Cardano light wallet that provides an interface for Cardano native staking system rather than operating a proprietary staking product. When a user delegates ADA through Eternl, the ADA remains inside the user self-custody wallet. Only the wallet stake/delegation rights are assigned to a Cardano stake pool. The ADA remains spendable while delegated. This makes Cardano staking different from locked staking models on some other proof-of-stake networks.
Quick Facts
Product Type: Self-custody Cardano light wallet. Network: Cardano. Staking Asset: ADA. Staking Mechanism: Native stake-pool delegation. Custody: Self-custody. Funds Locked: No. ADA Remains Spendable: Yes. Liquid Staking Token: None. Reward Rate: Variable by Cardano stake pool.
Stake Key Registration Deposit: 2 ADA (refundable — not a fee). Label: "Refundable Cardano stake-key registration deposit — not a fee." Transaction Fee: Normal Cardano network fee applies. Wallet Staking Commission: No separate universal Eternl staking commission. Stake Pool Fees: Vary by selected pool. First Rewards: Typically around 15–20 days after first delegation. Subsequent Reward Cycle: Every Cardano epoch. Epoch Length: Approximately 5 days.
Current Version
Current version at last verification: v2.1.7.1 (released September 5, 2026). Version numbers change — this is a dynamic field, not evergreen content.
Unstaking
Cardano staking does NOT use a conventional lock-up. Users can spend ADA while it remains delegated. If a user wants to completely stop staking and deregister the stake key, they can undelegate/deregister through the wallet. Current/pending epoch rewards can still follow Cardano's protocol timing. The refundable 2 ADA stake-key registration deposit is returned when deregistration is completed according to protocol rules.
Do not show "Unstaking period: 21 days" or "Unstaking period: 7 days" for ordinary Cardano delegation — the ADA itself was never locked in the first place.
Rewards
There is no fixed Eternl staking APY. Cardano rewards depend on stake pool performance, pool saturation, operator margin, pool fixed costs, pledged stake, overall Cardano network participation, and protocol parameters. Do not manually publish one universal ADA APY.
What to Check Before Delegating ADA in Eternl
- Saturation: How much ADA is delegated relative to the pool saturation point.
- Pledge: ADA committed by the operator.
- Pool Fees: Fixed cost and percentage margin charged from the pool rewards.
- Performance: Whether the pool reliably produces its expected blocks.
- Return on Stake: Historical/estimated reward performance, not a guaranteed future return.
Avoid telling readers to simply choose the highest displayed RoS.
Governance Requirement
To withdraw staking rewards, a wallet must also have an appropriate governance delegation. Eternl users can delegate governance power to a DRep or select an option such as Always Abstain. Once the governance requirement is satisfied, staking rewards can be withdrawn. This does not mean governance delegation changes ownership of the user ADA.
Reward Withdrawal
Staking rewards automatically contribute to the user delegated stake, allowing them to compound without manually claiming every epoch. Eternl also provides Manual Reward Withdrawal and Auto Withdrawal. When Auto Withdrawal is enabled, Eternl can include reward withdrawal in another outgoing transaction, reducing the need for a separate transaction and potentially saving an additional network fee.
Risks / Limitations
- ADA market volatility
- Stake pool underperformance
- Pool fee changes
- Pool retiring
- Pool saturation
- Wallet/recovery phrase security
- Malicious wallet extensions or phishing
- Cardano network transaction fees
Native Cardano delegation does not expose users to a liquid staking token or mandatory staking lock. Do not claim staking is completely risk-free.
