Kelp Staking: Understanding the Temporary Decrease in Staked ETH

For those staking ETH in the Kelp Vault via the Yay! Dashboard, an initial decrease in the staked ETH amount may occur. This is due to the weekly calculation of management fees (2% per annum) and interest by Kelp Vault, which takes place on different days. At times, the management fee may be deducted before interest is applied, leading to a temporary reduction. Over time, the interest rate is designed to surpass the management fee, allowing the staked ETH amount to gradually increase.

Kelp DAO estimates that staked ETH amounts could potentially exceed the original staked value within 2-3 weeks from the start of staking. However, this timeframe is not assured and may vary based on several factors, including market conditions and the timing of fee and interest calculations.

For more details on Kelp staking and the factors that influence your staked ETH, please refer to Kelp DAO’s official page: .

The update frequency for the Eigen Layer has been changed from every hour to once per day.

Following a recent security incident related to Neemo Finance, we recommend users revoke any smart contract approvals associated with the following tokens:

• yayASTR

• nsASTR

• nrETH

As , there was a security incident involving the Neemo Vault. While the risk to Yay! users remains relatively low, we still recommend revoking approvals to ensure the security of your assets. This is a precautionary step and aligns with best practices in managing token permissions.

When you interact with DeFi applications, you often give them permission (approval) to move tokens on your behalf. If those contracts are later compromised or no longer maintained, leaving those approvals in place can expose your assets to unnecessary risk.

Revoking approvals removes this permission.

You can safely revoke token approvals using the tool:

Steps:

1. Connect your wallet and select the Soneium network.

2. Look for any approvals related to yayASTR, nsASTR, or nrETH.

3. Click Revoke on each.

We will continue monitoring the situation and provide updates as needed. For any questions, please contact us .

Summary

• On July 5, 2025, Neemo Finance (Astar) was exploited via a compromised admin key, enabling over-minting of nsASTR and subsequent liquidity drains.

• Governance intervention secured 204,283,546.036 ASTR; a white-hat later returned 91.634 ETH.

• The community approved the Asset-Linked (Burn) Compensation Model; claims require burn-to-claim.

• The incident occurred on Neemo Finance. Yay! smart contracts remain secure. However, Yay! stakers who used the Neemo vault are affected through their nsASTR positions and should follow the steps below.

• Phase 1 — Immediate: Burn nsASTR to receive ASTR from the recovered pool at the Phase 1 compensation rate.

• Phase 2 — Long-Term: Future Neemo dApp staking rewards (minus minimal ops) are redirected to a compensation pool and distributed monthly to wallets that completed Phase 1 until pre-hack value is restored.

1. Redeem on Yay! Dashboard: Convert yayASTR → nsASTR ().

2. Claim on Neemo:

   1. Open

• Redemption on Yay! Dashboard: 1 yayASTR → 0.9949 nsASTR This redemption rate is the same as before the incident and has not changed.

• Phase 1 (Neemo burn-to-claim):

  • Per 1 nsASTR: expect ~0.8686 ASTR in Phase 1 (≈ 78.3% of pre-hack value).

Note: The remaining ~21.7% (vs. pre-hack value) is planned to be paid over time in Phase 2 to wallets that complete Phase 1.

• Questions about redeeming on the Yay! Dashboard (yayASTR → nsASTR): use our .

On April 18, 2026, an external attacker exploited the LayerZero bridge of Kelp DAO, the protocol we partner with for our ETH staking feature. Approximately 116,500 rsETH (roughly USD 292M, or about 18% of circulating supply) is reported to have been drained.

Current Situation

• Kelp has executed an emergency pause on its core contracts shortly after the incident was detected

• Major DeFi protocols including Aave, SparkLend, and Fluid have frozen their rsETH markets

• The backing of wrapped rsETH (on L2 networks) is facing temporary uncertainty

• rsETH on Ethereum mainnet is reported to remain fully backed, pending official confirmation from Kelp

Yay!'s Response

• New staking deposits are suspended, effective today

• We are in direct contact with the Kelp DAO team to confirm the scope of impact on agETH holders and the recovery timeline (Yay! Staking wraps agETH)

• Once official statements and a recovery schedule become available, we will provide updates promptly on this page, via in-app notifications, and on

Regarding Your Position

• As of now, rsETH markets on major protocols (Aave, SparkLend, Fluid, etc.) are frozen, and secondary market liquidity is lower than usual — larger trades may experience significant slippage

• The "Unstake" function depends on the status of Kelp's contracts and may take longer than usual to process

We sincerely apologize for the concern this may cause. We will continue to keep you informed as the situation develops.

Thanks to feedback from several wonderful community members, we've identified some issues with point calculations. First, we'd like to express our gratitude to everyone in the community who brought this to our attention.

We identified an issue in the snapshot data used to calculate rewards for StakeStone vault, StakeStone LP, and Kelp LP, which led to incorrect Yay! Gold and ???? Points being granted to some users. The fix has now been deployed, and a one-time adjustment has been applied.

Scope

The issue affected rewards earned:

• From StakeStone LP and Kelp LP since 11 September 2025

• From StakeStone vault since 29 September 2025

Other vaults, campaigns, and sources of Yay! Gold / ???? Points are not affected.

• We corrected the snapshot data used as the basis for reward calculation in the affected vaults.

• We recalculated past rewards using this corrected snapshot data.

• We then applied a one-time adjustment to both Yay! Gold and ???? Points for affected users so that balances now reflect the correct rewards.

• If you previously received fewer rewards than you should have, your Yay! Gold and/or ???? Points balance has increased.

• If you previously received more rewards than you should have, your Yay! Gold and/or ???? Points balance has been reduced accordingly.

• No action is required on your side; the adjustment has already been reflected in your account.

If you have questions about your Yay! Gold or ???? Points balance related to this adjustment, please contact us via this form: .

Regarding the security incident affecting Kelp DAO's rsETH cross-chain bridge that occurred on April 18, 2026 (UTC), we are pleased to report that, after approximately one month of industry-wide coordination and the efforts of the Kelp team, the incident has been fully resolved.

Resolution Status

• Kelp DAO's rsETH protocol has fully resumed (May 16). The exchange rate has been updated, EIGEN claims are distributable, and deposits/withdrawals are live on mainnet and L2s

• The reopening of Kelp's Always Gain vault (agETH) has been confirmed (May 18)

• Unstaking and withdrawals on Yay! Staking are now available as usual

About Yay! Staking

• Unstaking and withdrawals are available as usual

• Withdrawals may be settled primarily in stETH. Processing will proceed smoothly per Kelp's specifications

• We will continue to operate safely going forward

Closing Remarks

Since the incident occurred, Yay! has shared several updates on our , continuing to provide transparent information to our supporters.

Through industry-wide coordination (DeFi United led by Aave, Mantle, Consensys, Ethereum co-founder Joseph Lubin, Babylon Foundation, and many other contributors) and the dedicated efforts of the Kelp team over 30 days, this incident has been resolved.

We sincerely apologize for the concern this has caused, and we extend our heartfelt thanks to everyone who waited patiently throughout this period.

Thank you for your continued support of Yay! Staking.

Some Kelp Vault stakers may be eligible to claim the new LINEA token from the Linea ecosystem.

Key Details:

• The claim process is handled entirely by the Linea team, not Yay! or Kelp.

• Eligible users must visit the Linea Hub and connect their wallet to check eligibility and claim. → https://linea.build/hub/events/linea-airdrop

• Claim window: Open from Sep 10 to Dec 9, 2025.

Yay! stakers who staked via Kelp vault may be eligible, depending on when their assets were staked.

• The Kelp Vault had exposure to the Linea chain only until November 2024.

• This means only stakers who had positions before November 2024 were contributing to Linea’s ecosystem and are likely eligible.

• Stakers after that point were restaked to other protocols based on .

• Eligibility is determined by Linea LXP-L points accumulated during Linea campaigns.

• Some Yay! stakers may not meet the minimum threshold (15,000 LXP-L).

• Linea airdrop claims are live at:

• Only early Kelp vault stakers (prior to Nov 2024) may qualify.

• All claim conditions are managed by the Linea team.

For any issues related to the Linea airdrop, please consult the or directly.

Regarding the security incident affecting Kelp DAO's rsETH cross-chain bridge that occurred on April 18, 2026 (UTC), we are pleased to share that, after approximately three weeks of industry-wide coordination, decisive progress has been made toward resolution. This page provides the latest update.

Key Progress to Date

• DeFi United (an industry coalition led by Aave) has secured approximately $320M in support (137,700+ ETH), effectively covering the total damage (approximately $380M)

• Aave has fully liquidated the attacker's positions, with recovered collateral transferred to the Recovery Guardian (no impact on other users)

• A NY federal court has authorized the transfer of 30,766 ETH (approximately $71M) frozen on Arbitrum to Aave LLC (early morning JST, May 9)

• Kelp DAO has announced the full migration of rsETH's cross-chain infrastructure to the Chainlink CCIP/CCT standard (May 5)

As a result, the backing of rsETH is approximately 90% restored, and with the addition of the 30,766 ETH whose transfer was authorized by the NY federal court, full restoration is expected.

Regarding Your Position

• Unstaking and withdrawals will become available after Kelp's contracts have been reactivated

• The timing of reactivation depends on Kelp's announcement, and no specific date has been set at this time

• As the backing is restored, unstaking via Kelp is expected to become possible in due course

Looking Ahead

Since the incident occurred, we have shared 11 updates on our .

The impact on our supporters is expected to converge to a level significantly more limited than initially anticipated. Through the restoration of backing and the reactivation of Kelp's contracts, unstaking and withdrawals are expected to become available.

We will continue to share the latest developments on our .

We sincerely apologize for the continued concern this has caused.

Engaging in Yay! Staking involves interacting with various components of blockchain technology, each of which carries distinct risks. These can include technical challenges, such as smart contract vulnerabilities, oracle issues, and cross-chain transfer risks. Regular security assessments, commonly referred to as audits, are conducted to ensure the integrity and safety of the protocol’s code.

Smart Contract Integrity Risks

The functionality of the staking platform depends on smart contracts, which automate many aspects of the protocol. However, these contracts may encounter unexpected bugs or weaknesses, potentially causing disruptions or permanent loss of user assets.

Oracle Reliability Risks

The protocol relies on external data sources, or oracles, to provide accurate price feeds. If these oracles deliver incorrect information, experience outages, or are manipulated, this could lead to inaccurate transactions, including wrongful liquidations.

Cross-Chain Asset Transfer Risks

As assets move between different blockchains, Yay! relies on bridge mechanisms for secure transfers. Despite thorough evaluations, these bridges are not immune to attacks or liquidity issues, which could result in the misplacement or loss of funds during transactions.

Please refer to the Terms of Use for each specific vault.

Yay! has launched its own point tracking system to manage EigenLayer rewards earned through ETH staking and liquidity providing activities specifically within the StakeStone vault, as part of the Yay! ecosystem.

What Are Yay! EigenLayer Points?

Yay! EigenLayer Points are earned when you stake ETH in the StakeStone vault, or when you provide liquidity using yaySTONE. These points determine your eligibility for $EIGEN token rewards.

Why a New Point System?

Previously, all EigenLayer points were managed by StakeStone. As Yay! continues to grow, we’ve introduced our own point system—Yay! EigenLayer Points—to give users better visibility, faster updates, and support for more types of contributions like LPs. This also allows Yay! to expand its reward system more flexibly in the future. All points earned under this system are calculated and displayed directly in your Yay! Dashboard.

Season Timeline

• Season 1: December 8, 2024 – April 30, 2025

  • Claiming for Season 1 rewards will open a few weeks after the season ends. A separate announcement will include full instructions.

• Season 2: Begins immediately after Season 1 ends

• Points are updated hourly

• Total points are displayed directly on the Yay! Dashboard

• Points earned before December 8, 2024, were managed by StakeStone. If you participated during this period, you can view and claim your rewards directly via the StakeStone platform:

Please check your Yay! Dashboard to monitor your points. We’ll share more details once Season 1 claiming begins.

As a follow-up to our , the $KERNEL Season 1 airdrop is now officially claimable.

This guide is for users who deposited ASTR on Astar Mainnet and wish to withdraw it back to Astar Mainnet. Since direct withdrawal is not available, users must first bridge to Soneium and then bridge back to Astar Mainnet using the steps below.

Steps to Withdraw ASTR to Astar Mainnet

1. Bridge to Soneium

• Go to the Astar Vault page on the Yay! Dashboard.

• Bridge your ASTR tokens from Astar Mainnet to Soneium.

2. Bridge Back to Astar Mainnet

• Use the Astar Portal Bridge to transfer your ASTR tokens from Soneium back to Astar Mainnet.

• Astar Portal:

While withdrawal is possible, we encourage users to keep their ASTR tokens on Soneium for the following benefits:

• Users who bridge ASTR to Soneium continue earning points.

• ASTR tokens on Soneium provide a 10x point boost via the Yay! Dashboard.

• ASTR on Astar Mainnet will no longer earn points on the Yay! Dashboard.

• Yay! will cover the bridging fee (0.0001 ETH) for users who have deposited ASTR through Yay! Dashboard and have not yet bridged to Soneium and bridge back to Astar EVM. If you wish to proceed, please submit the required information via the form.

  • Apply for Bridging Fee Support: (available until March 31 2025, 23:59 JST)

If you have any questions please reach us . Thank you for your continued support and understanding.

The standard unstake process on the StakeStone Vault now takes significantly longer due to upstream changes by EigenLayer.

Key Updates:

• Withdrawal Time Extended: EigenLayer increased its normal unstake period from 7 to 14 days. Since StakeStone also needs to convert stETH to ETH via Lido (which adds another 14 days), the total waiting period is now approximately 28+ days.

• Instant Unstake Available: We’re working with the StakeStone team to mitigate this problem, and they will periodically refill ETH in the instant unstake pool. Users can use instant unstake with no downside compared to request unstake—there is no need to wait through the extended unstake timeline.

• Cancel Unstake Requests: A new feature now allows users to cancel their existing unstake requests. You can cancel and re-submit as an instant unstake if you prefer not to wait.

We understand this extended waiting period may cause inconvenience, and we appreciate your patience while we improve the experience. If you have any issues, feel free to reach out .
