Overview
BaseVault is the abstract base contract that all Aera V3 vault types inherit from. It provides the core infrastructure for guardian-based operation execution, Merkle proof verification, configurable hooks, and emergency pause functionality. Both SingleDepositorVault and MultiDepositorVault extend BaseVault to add depositor-specific logic.
The vault accepts batches of operations submitted by an authorized guardian. Each operation is validated against a Merkle tree that whitelists specific contract targets and calldata patterns. Hooks can intercept operations at multiple lifecycle points to enforce constraints such as slippage bounds, position limits, and approval cleanup.
For a conceptual overview of how BaseVault fits into the Aera V3 architecture, see Aera V3 Overview.
Functions
submit
Submits a batch of operations for the guardian to execute atomically. Each operation is validated against the guardian’s Merkle tree before execution. Submit hooks fire before and after the batch, and individual operations can have pre-hooks and post-hooks. Signature:pause
Pauses all guardian operations on the vault. Can be called by the guardian or the vault owner as an emergency safety mechanism. Signature:unpause
Resumes guardian operations after a pause. Can only be called by the vault owner. Signature:setGuardianRoot
Sets the Merkle root that defines the guardian’s allowed operations. Only callable by the vault owner. Signature:setSubmitHooks
Configures the before-submit and after-submit hook contracts for the vault. Only callable by the vault owner. Signature:checkGuardianWhitelist
Checks whether a guardian is still authorized on the vault’s whitelist. Can be called by anyone. Removes the guardian if it fails the whitelist check. Signature:guardian
Returns the address of the vault’s current guardian. Signature:owner
Returns the address of the vault owner. Signature:paused
Returns whether the vault is currently paused. Signature:Events
Submitted
Emitted when a guardian successfully submits a batch of operations.Paused
Emitted when the vault is paused.Unpaused
Emitted when the vault is unpaused.GuardianRootSet
Emitted when the guardian’s Merkle root is updated.SubmitHooksSet
Emitted when submit hooks are configured.Errors
Vault__Paused
Thrown when a guardian operation is attempted while the vault is paused.Vault__InvalidProof
Thrown when an operation’s Merkle proof does not verify against the guardian root.Vault__NotGuardian
Thrown when a non-guardian address attempts a guardian-only action.Vault__NotOwner
Thrown when a non-owner address attempts an owner-only action.Inheritance
BaseVault is the root of the Aera V3 vault hierarchy:
- BaseVault — Core guardian operations, Merkle verification, hooks, pause
- SingleDepositorVault — Adds single-depositor deposit/withdraw
- MultiDepositorVault — Adds multi-depositor ERC-20 vault units and order solving
