Keep your stablecoins safe and earn on Uniswap v4

unisafe is an NFT-owned vault (a “Manager”) that holds your tokens and earns fees by providing liquidity on Uniswap v4. A Stable manager holds stablecoins and earns auto-compounding fees in stablecoin pools; a Volatile manager runs any other Uniswap v4 pair, such as ETH/USDC. Whoever holds the Manager NFT controls the funds.

Create a Manager (minted as an NFT) and choose its type — Stable for pegged pairs, Volatile for any other Uniswap v4 pair. Fund it with tokens, deploy them to up to 32 pools in a single transaction, then collect or compound the fees and withdraw to any address at any time.

Pick Stable if you want to earn on pegged pairs like USDC/USDT with the least upkeep: you set one price range per pool when the Manager is created, it stays fixed, each pool holds one position, and reinvest compounds the earned fees for you. Pick Volatile if you want to provide liquidity to any other Uniswap v4 pair — ETH/USDC, WBTC/USDC and so on: you choose the price range each time you allocate, you can hold several ranges in the same pool at once, and recenter moves a position to a new range in a single transaction. Volatile has no reinvest, so you compound by claiming fees and allocating them again. The trade-off is upkeep and risk: a volatile pair moves, so a position can drift out of its range and stop earning until you recenter, and holding both sides of a moving pair can end up worth less than simply holding the tokens — the app computes that impermanent loss for each position. The type is chosen when the Manager is created and cannot be changed afterwards, so if you want both, create one of each.

A Volatile manager is the same NFT-owned contract wallet as a Stable one, configured for pairs that are not pegged to each other — any hookless Uniswap v4 pool, such as ETH/USDC or WBTC/USDC. Instead of one fixed range per pool, you choose the price range every time you allocate, and a pool can hold several positions at different ranges at the same time. When the price moves away, recenter rebuilds a position at a new range — remove, optional balancing swap, re-add — in one transaction. There is no reinvest on Volatile: you claim the earned fees to the Manager balance and allocate them wherever you want them next. Volatile managers are available on Ethereum, Unichain, Arbitrum and Base.

Major stablecoins such as USDC, USDT and DAI, on Ethereum, Unichain, Arbitrum and Base. Volatile managers run on the same four networks and take any hookless Uniswap v4 pair, including ETH/USDC and WBTC/USDC.

There is no deposit or withdrawal fee. A 10% protocol fee is taken only from the trading fees you earn; the remaining 90% stays in your Manager.

Yes. Each Manager is your own separate smart-contract wallet, deployed just for you, that is itself a singleton ERC-721 NFT — whoever holds that one NFT controls the wallet and is the only address that can move its funds. Both Stable and Volatile managers use hookless Uniswap v4 pools only, and unisafe never takes custody of your principal.

Your stablecoins provide liquidity to stable pools and collect swap fees. You can reinvest those fees back into the position to compound, or claim them to the Manager balance.

A Manager shows you two figures side by side, and they answer different questions. The plan — labelled “Pool APR · plan” — is what the pools your money sits in are paying right now: their recent trading fees divided by the value locked in them, projected out to a year, and averaged across your pools weighted by how much of your money is in each. It is what you look at before adding money. The fact — labelled “Earned” — is what this Manager has actually made and kept: the swap fees it has collected plus the ones still sitting in its positions, less the 10% protocol fee, in dollars, and the same amount expressed as a percentage a year against what you put in, over how long the money has been working. It is what you look at afterwards. They are not supposed to match, and a gap between them is information rather than a fault: a position sitting outside its price range earns nothing while the pool APR beside it stays positive, a position opened yesterday has barely had time to earn, and a tightly concentrated range can earn a multiple of the pool figure.

The app takes the pool’s trading fees over the last complete day, divides by the pool’s total value locked, and multiplies by 365. That is the same window on every network — printed as “· 24h” beside the figure — so two pools are always comparable, which they were not while some networks averaged a fortnight and others a day. Where the network has a Uniswap v4 analytics index, the smoothed figure sits next to it as “14d avg”: the identical calculation over the last two weeks. Read them together. One day is responsive, which is the point of it, and jumpy for the same reason — a single large swap can move it several-fold — while the fortnight is what says whether the headline is a trend or an accident. Neither is a promise about the future, and a pool younger than the window has less behind the number than it says.

Look at “Earned” on the Manager, or on any single position. It counts the swap fees that position has produced — both what has already been collected into the Manager’s balance and what is still accruing inside the position — valued at today’s prices, with the 10% protocol fee already taken off, so the number is what stays with you rather than what the pool paid. That fee comes off when fees are realised, which is why it is subtracted from the uncollected part too: those fees will be skimmed the moment anything moves them, and showing them whole would make the figure drop every time an operator worked. Open a position in Advanced mode and the same figure is broken into its parts — unclaimed, collected, and the protocol fee — so you can see where it comes from. The percentage beside it annualizes the net amount against what you put in. Impermanent loss is deliberately not subtracted from it: it is a different thing, it moves with the price rather than with trading, and each position charts it separately as “fees vs impermanent loss” so you can read the two together instead of losing both inside one blended number. If the figure carries a “≥”, it is understated: recentering and reinvesting have to realise the fees they find before they can move liquidity, and today they record only the new range or the liquidity added, never the fee amount. Those fees are yours and they are in your positions — they are simply missing from the running total, and the more often an operator works, the more is missing. The breakdown names that gap directly, as a “compounded” line with no amount against it, and the “fees vs impermanent loss” chart stops showing a net verdict on such a position: the same missing money is absent from the fee side and counted as a gain on the other, so any total of the two would be wrong twice over. A fix is on-chain work and will apply to Managers deployed after it.

Because it is computed on-chain, by the contract that draws the artwork, and it measures something narrower. For each open position it takes the fees earned but NOT yet collected, annualizes them over how long that position has been open, adds that up across positions and divides by their principal. Two consequences are worth knowing. It drops to almost nothing right after fees are collected, reinvested or a position is recentered — the uncollected pile it measures has just been emptied — and then climbs back as fees accrue again. And it values a volatile token by the live pool price against the stablecoin it is paired with, falling back to counting each token as one dollar only for pairs with no stablecoin leg, so it is an approximation rather than a market valuation. That is why it is drawn with a “~”. The figures on the site are the ones to read: the plan for what the pools pay, “Earned” for what you got.

Yes. The owner can authorize operator addresses to allocate, recenter, reinvest and claim fees on the Manager’s behalf. An operator can never withdraw funds, change the price oracle or authorize another operator.

Yes, and the cheapest way needs nothing installed: point your agent at https://unisafe.envelop.is/mcp and it can read your positions, the fees they have earned, who is authorised to operate a manager, and which of that manager's pools pays best — that server holds no key and cannot sign anything. Second, the agent skill is documentation your agent loads: what a Manager is, how Stable differs from Volatile, what the fees are, and which steps you have to do yourself in the browser; it needs no keys either. Third, the local MCP server runs on your machine, holds a dedicated operator key and places the transactions once you authorise its address as an operator. In Claude Code the skill and the local server arrive together as a plugin; other agents install the skill with one npx skills add command; on claude.ai you upload the skill folder as a zip.

An agent authorized as an operator can only move liquidity around inside the Manager: allocate idle balance, recenter a position, move a position from one of the Manager's pools into another, claim fees and reinvest them. It cannot withdraw funds to any address, change the price oracle, or authorize another operator — those are restricted to the NFT holder by the contract itself, not by the agent's good behaviour. Any swap the operator triggers must be vouched for by the price oracle and is rejected outright if it cannot be, and the owner revokes the agent at any time with a single setOperator transaction.

Each Manager is a singleton NFT. Transferring the NFT transfers control of all the tokens and positions it holds.
