Smart LP developers

For wallets, dashboards, yield aggregators, and keeper bots wiring deposits, withdrawals, reads, and indexing on the Safety Deposit Box Smart LP vaults. Each vault is an immutable ERC-20 share token over one Uniswap v3 position. Discover vaults from the registry, read the floor through the lens, and never hardcode a vault address.

Live addresses

The registry is the only source of truth for vault addresses on each chain, and vaults never move between chains. Delisting only removes a vault from the UI surface; the vault keeps working, so keep serving positions you already track.

Verifying a vault is genuine

Registry listing is a curation signal. To verify a vault carries the audited bytecode, fetch its runtime code and check all three: code length exactly 23,718 bytes, every linked library slot carries 0x4A2dA8e70b51595Bf564082A86336AbDDc62E32F, and the code with immutables, library slots and the solc metadata hash blanked to zero hashes to 0x1c32f1291fb1038d8c6506800210a217c649195efb2dd0134869d8776d1eb2e3. The same pin passes on both chains; the site applies it to every registry row before rendering (app/lib/smartLpCodePin.ts).

Discovery and reads

// SmartLpRegistry
count() ? uint256
vaults(index) ? address
all() ? address[]

// SmartLpLens (live)
viewAll(registry) ? VaultView[]           // whole floor in one call
viewVault(vault) ? VaultView
previewWithdraw(vault, shares) ? (out0, out1)   // net of the 10 bps retention

// VaultView: vault, pool, token0, token1, symbol0/1, decimals0/1, mode (0 FR / 1 BB / 2 ASK),
// baseIsToken0, poolFee, tickLower, tickUpper, spotTick, positionId, totalSupply,
// totalValueQuote, tvOk, capQuote, maxCapQuote, perfFeeBps, withdrawFeeBps,
// depositsPaused, settled, allBase, lastRecenterAt, feeManager

Shares are quote denominated (about one quote unit per 1e18 shares at genesis). Never present shares as token amounts; show USD and underlying values from the lens. Treat tvOk == false as value unavailable, never as zero TVL. USDG, USDC and USDT are 6 decimals.

Deposits and withdrawals

// Deposits (guarded by TWAP band + fresh Chainlink cross check, capped)
deposit(amount0, amount1, minShares, to) payable        // FR, BB pair deposit
zapDeposit(tokenIn, amountIn, minShares, to) payable     // FR, BB single token entry (swaps in the vault pool)
depositSingle(amountBase, minShares, to) payable         // ASK base only, swap free

// Withdrawals (never pausable, never gated, no oracle)
withdraw(shares, min0, min1, unwrapNative, to)           // proportional, in kind
zapWithdraw(shares, tokenOut, minOut, unwrapNative, to)  // single token exit, runs the guard

// Permissionless cranks
compound()                                               // collect fees, skim 10%, reinvest
harvest()                                                // harvest mode vaults only, pays the caller a reward

Every deposit function returns the minted shares, so an eth_call from the depositor is the quote: sign with minShares at 98% of the simulation. Native ETH on WETH quoted vaults is added on top of the declared amount (pass amountIn = 0 with msg.value). Approve the vault for the exact amount. A genesis deposit must be worth at least minFirstDepositQuote(). The 10 bps withdraw retention stays in the vault for remaining holders; show it before signing.

Stock vaults carry a Chainlink cross check that only runs while the feed is fresh. Equity feeds pause from Friday close to Monday 00:00 UTC, which widens the TWAP band instead of blocking; on Monday open a drifted pool briefly reverts FeedDeviation on deposits until arbitrage converges it. Probe availability with a 1 wei simulated deposit and gate the form with plain copy. Plain withdraw is never affected.

Staged V2 generation

V2 prices deposits on the vault basket instead of the TWAP, refunds the unused leg of a pair deposit, adds a permissionless settle() for single sided vaults, a depth gate on band vaults, and an exact previewWithdraw. Its ABIs are published so you can prepare; the guide tags every V2 row.

Smart accounts and ERC-6551 wallets are first class depositors (no EOA gate). Preflight the inner call from the account address so real selectors surface; gas comes from the signer. Questions and listings: simple@clutch.market.
