Blackbox Vaults

Blackbox is RFY's higher-conviction vault tier: a managed USDT vault built for strategies that need more freedom than passive yield. Depositors receive ERC-4626 receipt shares, while the share price reflects the vault's realized performance through NAV.

Blackbox is a higher-risk product. Returns are not fixed or guaranteed, and NAV can decline.

Inside the Blackbox

Blackbox is best understood as a managed capital engine, not a fixed-rate pool. Three layers work together throughout each rolling epoch.

The vault

USDT enters an ERC-4626 vault. Receipt shares represent each depositor's proportional claim on the vault's assets.

The strategist

A vetted strategist directly manages the mandate, combining options premium capture with selective momentum exposure and controlled position sizing.

The reserve

Eligible idle collateral may be deployed into curated onchain opportunities when appropriate, adding a yield layer while capital is not in active strategy positions.

The result is a continuous loop: capital is accounted for onchain, deployed by the strategist within the mandate, settled back into the vault, and reflected in totalAssets() and receipt-share NAV. Deposits and withdrawals align with the vault's rolling epoch windows rather than an always-open liquidity model.

Blackbox vault architecture

Deposit and withdrawal requests may be queued until the applicable epoch, settlement, or redemption window. Check the live vault page for the current status before submitting a request.

Live deployments

Both Blackbox vaults currently accept USDT.

Always confirm the selected network, vault contract, and deposit-token address before approving USDT or depositing.

Contract architecture

Blackbox uses the same core vault contracts as RFY's other vaults. The post-BailSec changes were minor and were not specific to Blackbox; Blackbox does not introduce a separate product-specific contract system.

See Audits and Contract Addresses.

Fees

Blackbox currently charges no management or performance fee. Confirm the terms shown in the RFY app before depositing because vault terms may change.

Principal risks

  • Strategy and market risk — Options and momentum positions can lose value, especially during sharp or persistent market moves.

  • Directional exposure — Blackbox is not designed to remain fully delta neutral at all times.

  • Strategist and counterparty risk — Offchain execution and settlement depend on the strategist and the venues used.

  • Liquidity risk — Deposits and withdrawals may be queued around rolling epochs.

  • Smart contract and protocol risk — RFY contracts and any onchain yield protocols used can fail or be exploited.

  • Performance risk — Backtests and prior returns do not predict future results.
