A lending protocol's governance token can sit idle in your wallet or help protect the protocol. When collateral falls below 100% of what a borrower owes, the gap becomes bad debt that someone must absorb. A common answer is a staking backstop: locked tokens that earn rewards for stakers and can be cut to cover a deficit.
On Aave, that backstop is called the Safety Module, and stkAAVE is the staked token you receive when you lock AAVE into its legacy pool. The AAVE in the module was designed as insurance against a shortfall, which is why stakers earn rewards in return (source: Aave docs, Glossary). Recovering your AAVE requires a timed exit, and since March 23, 2026 it starts with a 2-day cooldown (source: Aave Governance, AIP 459 Reduce Safety Module Emissions). Once the cooldown ends, you unstake inside a 2-day window (source: Etherscan, stkAAVE contract read).
A newer system called Aave Umbrella stakes aTokens (the interest-bearing tokens you receive when you supply assets to Aave) and GHO (Aave's own stablecoin) as it gradually replaces the legacy module (source: Aave Docs, Umbrella). stkAAVE now operates beside it as a separate position with independent rules.
What is stkAAVE?
stkAAVE is the token the legacy Safety Module credits to you when you stake AAVE, and it represents the AAVE you have locked in that pool. It is an ERC-20 token on Ethereum, which means your wallet displays it and you can send it to another address like any other token (source: Etherscan, Staked Aave (stkAAVE)).
The legacy module runs three staking pools, one each for AAVE, ABPT (a Balancer pool token) and GHO. Umbrella pools accept aTokens such as aUSDC, aUSDT and aWETH, as well as GHO (source: Aave Labs, Stake). stkAAVE is the staked token of the AAVE pool, and staking moves AAVE you already own from your wallet into the module, which changes where those tokens sit while the total AAVE supply stays exactly the same.
The AAVE token is the governance token of the Aave lending protocol, where lenders supply assets and borrowers post collateral to take loans. Holding stkAAVE keeps you exposed to the AAVE price, because each staked token is redeemed for AAVE at the exit. What it adds are two features that liquid AAVE lacks: staking rewards and slashing risk (source: Aave docs, Glossary). A slash needs an onchain governance vote (source: Aave Labs, Stake). The maximum for stkAAVE is currently 0% (source: Etherscan, stkAAVE contract read).
To stake, you need AAVE in a self-custody wallet, and purchasing the token on an exchange is the usual first step. On BloFin, AAVE/USDT Spot buys the token itself, while the AAVEUSDT Perpetual is a USDT-settled contract that tracks the AAVE price and gives you price exposure only. Spot is the route when you plan to stake: once you buy AAVE on AAVE/USDT Spot, you withdraw it to your personal wallet and stake from there.
Trading costs differ between a spot purchase and a perpetual position, so compare the maker and taker rates for both markets on the BloFin fee schedule before you place the order.
How the legacy Safety Module staking cycle works
Entering the legacy Safety Module takes two wallet transactions on Ethereum, approve and then stake, and leaving takes two more, activate the cooldown and then unstake. You hold stkAAVE between those steps while Safety Incentives accrue. Outside the period right after a slash, the exit takes at least 2 days.
Staking starts with an approval, because the staked token contract needs an allowance before it can move AAVE out of your wallet. Your first transaction authorizes that allowance. The second sets the amount and confirms the stake, after which the AAVE sits in the module and starts earning Safety Incentives (source: Aave Labs, Stake).
Suppose you hold 100 AAVE in a self-custody wallet, approve the module, stake all 100 AAVE and receive 100 stkAAVE at the same address. While the position is open, you can claim the Safety Incentives it earns at any point, either while you are staked or after you unstake (source: Aave Labs, Safety Incentives). Claiming is its own transaction with no effect on the cooldown (source: Aave Labs, Unstake). You can therefore collect rewards for months and still have the full exit ahead of you.
When you decide to recover the 100 AAVE, you activate the cooldown with one transaction, wait for it to finish, and then send the unstake transaction, which moves the AAVE out of the module and back into your wallet. The same two-step exit applies to Umbrella positions and to the legacy module alike (source: Aave Labs, Unstake).
Every step in the cycle is an Ethereum mainnet transaction, so each one requires a gas fee paid in ETH. Maintain some ETH in the staking wallet for the entire life of the position, because the unstake step has the tightest deadline and is the worst moment to discover that the wallet cannot cover a transaction fee.
Cooldown and the unstake window
The cooldown is a mandatory wait that starts only when you activate it. For stkAAVE it has lasted 2 days since March 23, 2026, when governance executed AIP 459 and cut it from 7 days (source: Aave Governance, AIP 459 Reduce Safety Module Emissions).
As late as September 2025 the same cooldown was 20 days (source: Aave Governance, ARFC Safety Module & Umbrella Emission Update), so a stkAAVE guide that still counts 20 days predates both cuts. After the cooldown, you have 2 days to unstake (source: Etherscan, stkAAVE contract read). Missing that window sends you back to the start, because you must activate the cooldown again and sit through the full wait once more (source: Aave Labs, Unstake). Holding stkAAVE starts no countdown of its own, so a position you staked a year ago still needs the full cooldown on the day you decide to leave. Start it on a day that puts the window on dates when you know you can sign a transaction.
Umbrella keeps the longer timing: a 20-day cooldown followed by a 2-day unstake window. Governance can change that cooldown length through a vote (source: Aave Docs, Umbrella). The same exit rules therefore cost very different amounts of time depending on which position you hold.
Imagine a 50 AAVE stake on which you activate the cooldown for all 50 stkAAVE on day 0. The window opens on day 2 and closes on day 4, and suppose you miss it because you were traveling or because gas fees spiked and you decided to wait. Nothing is lost immediately, since you continue to hold 50 stkAAVE and the position keeps earning rewards, but the only way forward is a fresh cooldown. Started on day 4, it ends on day 6, so the exit you planned for day 2 moves to day 6. The same miss on an Umbrella stake is far more expensive: a window that opens on day 20 and closes on day 22 is followed by a fresh 20-day cooldown, so an exit planned for day 20 opens no earlier than day 42. In both cases the mistake is treating the window as flexible, because the unstake option ends the moment it closes.
Your AAVE stays staked until the unstake transaction confirms. A legacy slash lowers the exchange rate, the rate at which stkAAVE redeems for AAVE, including stkAAVE that is already in cooldown (source: BGD Labs, Stake token properties). Umbrella stake tokens follow the same rule, with rewards accruing and funds staying slashable during the cooldown (source: Aave Docs, Umbrella). That design closes an obvious loophole, because a staker who could leave the moment a deficit appeared would collect rewards in good times and pass the losses to everyone who stayed.
Slashing in the legacy Safety Module
Slashing is the reduction of staked assets to cover a shortfall. In the legacy module, a slash can happen only through an onchain governance vote, up to a maximum share that governance sets (source: Aave Labs, Stake). For stkAAVE that maximum now stands at 0% (source: Etherscan, stkAAVE contract read).
Consider what a slash would do to a 100 stkAAVE position if governance first raised that maximum and then approved a slash of one tenth of the AAVE pool, a figure chosen only for the arithmetic. The AAVE in the pool would fall by a tenth while the number of stkAAVE tokens stayed the same, so each stkAAVE would redeem for 0.9 AAVE, and your 100 stkAAVE would return 90 AAVE at the exit. Your wallet would still show 100 stkAAVE. The loss would appear only as a lower exchange rate on each token (source: BGD Labs, Stake token properties). Umbrella stake tokens handle a slash the same way, by lowering the value of every share (source: Aave Docs, Umbrella).
The maximum slash is itself a governance parameter, and slashing is the risk Safety Module stakers were originally paid to carry. For stkAAVE the maximum fell in steps, from 30% before Umbrella to 20% in June 2025 and 10% in July 2025. Governance proposed the final cut to 0% in September 2025 (source: Aave Governance, ARFC Safety Module & Umbrella Emission Update). A later vote could raise it again, so treat any number you read as current only until the next vote.
So far the risk has stayed theoretical, because no slash has ever been carried out in the legacy module's history (source: Aave Labs, Umbrella). Safety Incentives exist to compensate stakers for the chance that their assets are slashed to cover a deficit (source: Aave Labs, Safety Incentives). With the stkAAVE maximum at 0%, the exposure to watch is a future proposal that raises it, so read any vote that touches the stkAAVE slashing parameter before deciding whether to stay staked.
Legacy Safety Module vs Umbrella
Umbrella is Aave's replacement for the legacy Safety Module. It stakes aTokens and GHO and slashes automatically within one asset on one network once a deficit passes its offset, the bad debt the Aave DAO covers first (source: Aave Docs, Umbrella). The legacy module stakes AAVE, ABPT and GHO and slashes by governance vote (source: Aave Labs, Stake).
| Dimension | Legacy Safety Module | Umbrella |
|---|---|---|
| Staked assets | AAVE, ABPT, GHO | aTokens (for example aUSDC) and GHO |
| Token you hold | stkAAVE, stkABPT, legacy stkGHO | A stake token for the matching asset |
| Slash trigger | Onchain governance vote | Automatic, once a deficit exceeds its offset |
| Risk scope | The whole staked pool | One asset on one network |
| Exit timing | stkAAVE: 2-day cooldown, 2-day window | 20-day cooldown, 2-day window |
| What a stkAAVE holder does | Keep the position as it is | Stake an aToken separately, if wanted |
The two systems will overlap for some time, because Umbrella is taking over from the legacy module in stages, and stkAAVE and stkABPT keep working throughout. Holders of those two tokens are not required to take any immediate step (source: Aave Docs, Umbrella). Slashing on stkAAVE is already at 0% (source: Etherscan, stkAAVE contract read), and governance cut slashing on stkAAVE/wstETH BPTv2, the Balancer pool token module, from 10% to 0% in AIP 459 (source: Aave Governance, AIP 459 Reduce Safety Module Emissions). A stkAAVE holder can therefore keep the stake exactly as it is.
The reason for the switch is capital efficiency, because Umbrella stakes aTokens that match the asset at risk. Burning staked aUSDT covers USDT bad debt directly, with no market sale required (source: Aave Docs, Umbrella). Covering the same deficit from the legacy module would mean selling AAVE, a token unrelated to the asset that went into deficit (source: Aave Labs, Umbrella).
Asset isolation changes what a deficit means for you, which is easiest to see if you hold 100 stkAAVE and also stake aUSDC in Umbrella on Ethereum. A USDC deficit on Ethereum would first be set against the configured offset for USDC. Any amount above that would be covered automatically by burning staked aUSDC (source: Aave Labs, Umbrella). Your stkAAVE could be touched only if governance raised its 0% maximum and then voted for a legacy slash. The common mistake is to assume both stakes share one risk pool, an assumption that breaks the first time a single asset's deficit is covered by the stakers of that asset alone.
Voting power while AAVE is staked
Staking AAVE keeps your governance power intact, because holders of AAVE, stkAAVE and aAAVE (the aToken you receive for supplying AAVE to the Ethereum V3 market) receive governance power in proportion to the sum of those balances on Ethereum mainnet (source: Aave Docs, Governance).
Moving 100 AAVE into stkAAVE therefore keeps your total exactly where it was. That total carries two separate powers: proposal power, which lets you create a proposal, and voting power, which you use to vote for or against active proposals. You can delegate the two together or separately to any Ethereum address (source: Aave Docs, Governance).
Splitting the two is useful while you are staked. You might delegate voting power to someone who follows every proposal closely while you retain proposal power, and because delegation moves no tokens, your AAVE stays staked and your stkAAVE keeps earning Safety Incentives the entire time. When you would rather decide yourself, you can vote with AAVE and stkAAVE directly from the same wallet.
Protocol changes pass through Aave governance, from forum discussion and an offchain temperature check to a formal onchain proposal. At the onchain stage, token holders and their delegates vote with AAVE, stkAAVE or aAAVE (source: Aave Docs, Governance). That includes the votes that set Safety Incentives and the maximum slash, so a stkAAVE holder votes on the parameters of the stake itself.
Your voting weight also follows the staked balance through every stage of the exit process. During a cooldown, and after a missed window, you still hold stkAAVE, so your weight is unchanged, and once you unstake, the AAVE returns to your wallet and counts toward the same total as liquid AAVE.

Frequently asked questions
What happens if I stake more AAVE during an active cooldown?
Your running cooldown carries on unchanged and covers only the stkAAVE that was in it when you activated it. The newly staked AAVE needs a cooldown of its own, started and completed separately, before you can unstake it. The same rule shapes partial exits: once the window opens, you can unstake only the amount that was in cooldown, and unstaking resets the cooldown to zero for that amount, so any balance still staked needs a fresh cooldown before it can leave (source: Aave Labs, Unstake). Plan each top-up and each partial exit as a separate cooldown.
Does transferring stkAAVE to another wallet carry the cooldown with it?
A transfer moves the tokens without their cooldown. The sending wallet keeps its own cooldown status, and the receiving wallet has a status of its own, so stkAAVE that arrives at a new address does not inherit the sender's cooldown (source: Aave Labs, Unstake). A cooldown the receiving wallet already started still covers only the amount it recorded at activation, so the incoming tokens need a new cooldown that covers them (source: BGD Labs, Stake token properties). That matters when you consolidate wallets during an exit, because sending stkAAVE to a fresh address near the end of a cooldown means the new address begins the wait from zero.
How does stkABPT differ from stkAAVE?
stkABPT is the staked token of the legacy module's second pool, which takes ABPT, a Balancer pool token, where the stkAAVE pool takes plain AAVE (source: Aave Labs, Stake). Both tokens sit in the same module and use the same cooldown-then-unstake sequence, though governance sets the waiting time for each token separately. The bigger difference shows at the exit: unstaking stkABPT returns the Balancer pool token, so getting back to liquid AAVE takes a further withdrawal from the Balancer pool itself. Check which staked token your wallet holds before you plan an exit, because the two names appear similar.
What happens to GHO staked in the legacy Safety Module?
Legacy staked GHO, known as stkGHO, is moving to savings GHO (sGHO), a vault that pays a fixed annual percentage rate (APR) with no cooldown and no slashing risk. The route is to withdraw GHO from the legacy contract and deposit it into the sGHO vault. Holders who want higher rewards and accept slashing can instead activate a cooldown on legacy stkGHO, unstake the GHO, and stake it in Umbrella (source: Aave Docs, Umbrella). Slashing on legacy stkGHO is already disabled (source: Aave Labs, Stake).
Where do legacy Safety Incentives come from?
Rewards on the legacy module, including stkAAVE, are paid mainly in AAVE. Aave Governance sets the emission parameters, and the tokens come from the Ecosystem Reserve, which holds AAVE, and/or the protocol treasury, so AAVE holders vote on how much goes to stakers and how it is spread over time (source: Aave Labs, Safety Incentives). stkAAVE emissions currently run at 150 AAVE per day (source: Aave Governance, Safety Module August 2026 Allowance Update). Umbrella uses a different model, an emission curve that pays more when staking sits below a target level and less once staking passes it (source: Aave Docs, Umbrella).
Which network do I vote on when I hold stkAAVE?
Each Aave proposal names its own voting network, which can be a lower-cost chain such as Polygon PoS or Avalanche C-Chain, while your balances and delegations stay on Ethereum mainnet. The voting network checks them against a snapshot of an Ethereum block using storage proofs, a cryptographic proof that your balance existed in that block, so your stkAAVE never moves (source: Aave Docs, Governance). Smart contract wallets that exist on only one network can set a voting representative, a separate address allowed to vote for them on each network.
