Embedded yield from Aave
Stable Vaults enable fintechs to embed stable-rate earning on stablecoins directly into their products.
What are Stable Vaults?
Predictable stablecoin earning for fintechs.
Traditional DeFi lending rates fluctuate with market utilization. Stable Vaults turn that volatility into a stable-rate product layer that is easier to explain, forecast, and embed.
Stable. Predictable. Trustworthy.
- No rate volatility.
- Per-user rates for loyalty, campaigns, or tiers.
- Yield compounds every second, automatically.
- Easy for end users to understand.
The rate you see is locked at deposit and compounds every second. Market yield moves underneath; the Vault absorbs the swings to hold your rate steady.
Why Stable Vaults
Bring stablecoin earning into your product.
Stable Vaults package DeFi-powered yield inside familiar product flows, with supported assets, rates, and redemptions all built in.
Multi-asset deposit and withdrawal
Deposit one supported stablecoin, redeem another: yield fits the rails already in your product.
Per-user rates
Assign rates by activity, tier, loyalty, or promo: the vault tracks each user automatically.
Multi-chain earning
Capital is spread across multiple chains and lending markets: lower fees, deeper liquidity, by default.
How it works
Deposit, earn, withdraw.
Stable Vaults keep the user experience familiar while the vault manages liquidity, accounting, and DeFi-powered yield beneath it.
Deposit
Users add a supported stablecoin through the product surface they already use.
Earn at a stable rate
The vault tracks the user's balance against a predictable stable rate.
Withdraw
Users request withdrawal and redeem through the same surface, across all supported assets.

FAQs
Each deposit accrues at a fixed per-second rate set by its assigned SubVault, so returns stay predictable no matter how underlying market rates move. An off-chain rebalancer continuously optimizes yield allocations to sustain those committed rates, absorbing market volatility at the protocol layer instead of passing it to depositors.
The vault continuously tracks its assets against its obligations to depositors. If earned yield falls short, principal is always guaranteed and an authorized party can top up the system to keep every position fully withdrawable; if assets exceed obligations, an authorized caller may sweep the surplus to the treasury—though never in a way that would leave the vault unable to cover what it owes.
Yes, because the Stable Vault supports multiple assets and is able to swap commonly denominated stablecoins while requiring a 1:1 exchange.
Slippage and swap/venue fees are funded by an external source. User deposits are never used to pay for slippage or fees and a 1:1 exchange is enforced at the smart contract layer.
Users never directly interact with bridging functionality. The funds deposited into the system are bridged cross-chain by a risk steward which pays for the bridging fees.
Every new external contract which is able to handle user deposits must be allowlisted and is subject to a timelock delay before the allowlist takes effect. Every allowlisted bridge and yield source is publicly auditable at any time.
Control splits into two on-chain tiers granted through an access manager. A fully-trusted Admin multisig, behind execution timelocks (seven days, up to fourteen for the most sensitive changes), handles high-risk actions like adding strategies, upgrades, top-ups, and claiming surplus interest. A partially-trusted Manager/Operator role, which can be granted to one or more parties, does frequent, lower-risk work such as assigning SubVault rate tiers and rebalancing, with no timelock but under constant off-chain monitoring. If a Manager is ever compromised, a guardian can revoke it instantly, and every role, allowlisted strategy or bridge, and parameter stays publicly auditable on-chain.
Deposits are synchronous: users approve the StableVault contract as spender, then call deposit. Withdrawals are two-step and asynchronous due to the system's multi-chain design. When local liquidity is sufficient, both steps can execute atomically; otherwise, the risk steward rebalances assets to support the withdrawal.
