Transaction Lifecycle

Deposits

  1. User Deposit: User calls deposit() with assets

  2. Immediate Minting: Shares minted synchronously at current PPS

  3. Asset Custody: Assets transferred to strategy for allocation

  4. Hook Execution: Strategist executes hooks to deploy capital

  5. PPS Updates: Validators provide updated PPS reflecting new positions

PPS Updates

  1. Off-Chain Calculation: Validators calculate PPS independently

  2. Signature Generation: Validators sign PPS with private keys

  3. Aggregation: Signatures collected and submitted to oracle

  4. Validation: Oracle verifies signatures and quorum

  5. Forwarding: Validated PPS forwarded to aggregator

  6. Strategy Checks: Aggregator runs dispersion/deviation checks

  7. Storage: PPS stored and made available for vault operations

Strategy Management

  1. Hook Approval: Strategist proposes new hook root

  2. Timelock Period: 15-minute delay configurable by governance for strategy hooks

  3. Execution: Hook root updated and new strategies enabled

  4. Guardian Oversight: Guardians can veto malicious updates

Redemptions

  1. Redeem Request: User calls requestRedeem() with shares

  2. Redeem Slippage: User optionally calls setRedeemSlippage() (default 0.5%)

  3. Share Escrow: Shares transferred to escrow contract

  4. Fulfillment: Strategist executes hooks to free up assets

  5. PPS Validation: Slippage protection against recorded request PPS

  6. Asset Claim: User calls withdraw() to receive assets

PPS Validation

Flexibilty and security is economically enforced by validators submitting PPS, supported by oracle infrastructure in Superform core. If interested in becoming a SuperVault validator, we recommend reading Become a Validator.

Validators currently use a ECDSAPPSOracle which validates price updates using cryptographic signatures from the decentralized validator network.

  1. Message Construction: keccak256(abi.encodePacked(strategy, pps, ppsStdev, validatorSet, totalValidators, timestamp))

  2. Signature Recovery: Uses ECDSA to recover signer addresses

  3. Validator Verification: Checks signers against registered validator set

  4. Quorum Enforcement: Requires minimum number of signatures

  5. Duplicate Prevention: Prevents the same validator from signing twice
