QuantumPoolsMEV & Slippage

MEV & slippage: what we remove, and what no one can

Providing liquidity is not trading. Because QuantumPools never swaps to re-center a position, there is no swap to slip and no swap to sandwich — but a re-center is still a public transaction, so some risk lives on the chain, not with us. Here is the honest line between the two.

We extract nothing from you, and we remove the costs we control — but we don't claim immunity from the chain itself.

Protocol & keeper MEV: removed. Chain-level MEV: mitigated, not eliminated.

01 · The starting point

No swap, so no swap slippage

A re-center preserves the position's width and rebuilds it from the tokens it already holds. Nothing is traded, so there is no swap slippage and no price impact from us. Every deposit and withdrawal additionally carries minimum-amount floors that you set.

"No slippage" is a statement about us, not about the pool. Impermanent loss is real, and the value of a position still moves with price — re-centering lowers the cost of following the price, it doesn't remove the loss. See Impermanent Loss for the denominator behind that.

02 · The honest split

Two kinds of MEV

MEV — value a transaction ordered around yours can capture — comes from two very different places. We are precise about which one we remove.

Where it comes from	Our posture	Why
The protocol & the keeper	Removed	Fees are paid to the position owner, never to whoever sends the transaction. Every fund-moving path is owner-gated, and the keeper never chooses the new range — it is derived on-chain from your own saved width. The invariant suite asserts the keeper's balance is zero after ~40,000 randomized keeper actions.
The chain itself	Mitigated, not eliminated	A re-center is a public transaction, and any public transaction can be observed and front-run. A re-center mint can be JIT-sandwiched at the pool level like any other liquidity action.

protocol & keeper MEV → removed · chain-level MEV → bounded

03 · The guard rails

How we bound the part we can't remove

We don't pretend chain-level MEV is gone. We make it expensive and small:

Per-transaction slippage floors. A re-center carries minimum-out amounts on both removing the old liquidity and minting the new range, so it can't settle at a manipulated price.
A deadline. The transaction expires if it isn't included promptly, so it can't be held and executed at a worse moment.
Two prices must agree. A position only moves when the pool's 30-minute average and the live price both say it has left its range — an optional on-chain guard rejects a re-center when the live price has strayed too far from that average, which makes nudging the price to force a move costly.
Withdrawals skip all of it. A withdrawal takes no 30-minute average and no price check — you get both tokens back at the pool's current ratio, with no swap, at any time.

Still true: these bound the exposure; they do not erase it. A public chain gives everyone the same ordering risk, and we won't tell you otherwise.
