How to lock liquidity on Robinhood Chain with the Safety Deposit Box

The Safety Deposit Box is the liquidity locker of Robinhood Chain. Teams lock their LP so holders can verify that nobody, including the team, can pull the pool. It also vests plain tokens with an immutable schedule. Every token that graduates on Stonklauncher bonds its raise into a pool whose LP position lands in the box permanently, which is why launcher tokens carry the LP locked badge.

What you can lock

How a lock works

1. Pick what to lock. Choose a Uniswap V3 LP NFT, a native ETH Uniswap V4 position, an up. DEX concentrated or v2 LP position, or a plain ERC-20 balance for vesting.
2. Pick the schedule. Permanent (no unlock ever), a hard cliff that releases everything on one date, or a linear unlock that releases over time.
3. Choose the fee mode and deposit. LP locks pick a fee tier that decides how collected swap fees split between the lock holder and the Safety Deposit Clock In. Token vesting pays a flat 1 bps deposit fee and nothing else.
4. Hold the receipt. The desk mints a transferable lock receipt NFT. Whoever holds it collects the fees and, on non permanent locks, withdraws once the schedule allows.

What the box guarantees

• No admin path to principal. The locker owner can change fee parameters for future locks but cannot withdraw, pause, or reassign an existing lock. Permanent locks have no unlock at all.
• Fees stay yours. Swap fees on a locked LP position keep accruing. The lock receipt holder collects them from the desk, with the protocol share routed to the Safety Deposit Clock In that pays activated StonkBrokers.
• Receipts are transferable. A lock receipt is a standard ERC-721, so a team can hand fee rights to a multisig or sell them without touching the underlying liquidity.
• Vesting is immutable. Token vesting schedules cannot be cancelled, paused, or clawed back once created, and each vest escrows in its own vault so a hostile token can only ever affect its own lock.
• Audited. The Safety Deposit Box ships a Hashlock Certified audit report, linked from the docs.

Smart LP lives in the same box

Smart LP volatility farming vaults are Safety Deposit Box vaults that actively market make Robinhood stock tokens on canonical Uniswap V3 pools and compound the swap fees back into the position. If you want yield on GME, NVDA, TSLA, AAPL, USDG, ETH, or $STONKBROKER rather than a static lock, that is the desk to open. The full explainer is in the stock token market making guide.

How to verify a project locked its LP

• On a Stonklauncher token page the Safety Deposit Box panel lists every locked pool, its lock receipt id, and pending fees.
• On the locker desk the feed lists every lock on chain with its schedule and unlock date. Permanent locks read forever.
• On Broker Tools or Blockscout you can read the lock receipt owner and the locked position directly from the contracts. Locked TVL is also reported to DefiLlama under StonkBrokers.
