What It Does

Aera V3 is a noncustodial, trustless smart contract protocol for on-chain treasury and yield management. It provides the vault contracts, permission model, and extensibility framework that powers the majority of Gauntlet’s vault infrastructure across Ethereum, Arbitrum, Base, Optimism, Polygon, and Avalanche. Aera V3 handles asset custody, operation validation, and hook-based extensibility while Gauntlet handles curation, strategy, and risk management.

​
How Gauntlet Uses It

Gauntlet deploys Aera V3 vaults in two configurations:
  • Single-depositor vaults serve dedicated treasuries where one entity deposits capital and Gauntlet manages strategy execution. These use SingleDepositorVault contracts with time-delayed fee calculation.
  • Multi-depositor vaults accept deposits from multiple participants through a Provisioner contract that handles minting, redeeming, and async order fulfillment. These use MultiDepositorVault contracts with unit-based fee calculation.
Both configurations support a hook system for custom behavior at lifecycle points and a constrained guardian model where all operations are validated against on-chain Merkle trees. For architectural deep-dives on guardians, hooks, and cross-chain mechanics, see the Aera V3 Architecture section in the Contracts tab.

​
What Integrators Touch

Aera V3 vaults expose the standard ERC-4626 tokenized vault interface. Integrators use the same deposit/redeem patterns described in the Deposits and Withdrawals guide. Key integration considerations:
  • Vault type matters: Single-depositor vaults have direct deposit/withdraw on the vault contract. Multi-depositor vaults route through a Provisioner with async fulfillment. See Vault Types.
  • Fees: Aera V3 includes a FeeVault contract for on-chain fee accrual and claiming. Partners can configure fee recipients. See Fees.
  • Wrapper vaults: Partners needing bespoke allocations or custom fee configurations can use wrapper vaults that deposit into underlying Gauntlet vaults. See Wrapper Vaults.
  • Data: Vault metrics are available through the Gauntlet API and on-chain. See Displaying Data.
