ETH liquidity sits under the BEDROCK price. It only grows, only moves up, and nothing in the contract can withdraw it. Bedrock does not promise a floor. It publishes how far away the floor is.
Depth to refusalread from the contract once the pool is live
Every buy pays 3% in ETH. That fee is split in two and put to work under the price. The picture below is the whole protocol; the rest of this page is the detail.
01 Stage Liquidity
Half of every buy fee becomes ETH liquidity under the price: The Refusal. Nothing in the contract can withdraw it.
02 Buyback
The other half runs a core. It buys BEDROCK back, then stages fresh ETH just under the new price, in one transaction.
03 Absorb Sells
A sell runs into that liquidity instead of empty space. The protocol buys the dip with ETH it already placed.
The pool
BEDROCK trades against native ETH in one Uniswap v4 pool run by the Bedrock hook. The hook refuses to create any other pool, and takes its fee on every buy that goes through it.
Anyone can provide liquidity to that pool and take it back out. The liquidity the protocol places, The Refusal and every staged layer, belongs to the hook and has no withdrawal path. That is the liquidity depth to refusal measures.
Buyback and stage liquidity
Half of every buy fee funds cores. A core buys BEDROCK back, then immediately stages fresh ETH just under the new price. Without that second step, the first seller would take the move straight back.
Cores fire at a random interval between 0 and 10 minutes. Nobody has to be trusted to run them: anyone can call the contract once the interval has passed, and is paid a small bounty for it.
Permanent
The other half of every fee becomes The Refusal: ETH liquidity sitting below the price, held by the hook. When the price rises, new ETH is placed higher. When it falls, nothing moves down. The Refusal never steps back.
It cannot be withdrawn. Not by the team, not by an admin key, not in an emergency. There is no function for it, and the pool itself rejects every removal:
function beforeRemoveLiquidity(...) external view
onlyPoolManager returns (bytes4)
{
revert LiquidityIsPermanent();
}The limit
A sell larger than The Refusal's depth cuts straight through it, and the price keeps falling. The mechanism absorbs selling up to a limit. It does not remove the limit.
That is why the depth is published, block by block, from the contract: so you can size the limit yourself instead of assuming it is infinite.
The fee
The fee is taken on buys only, and always in ETH, because both of its jobs need ETH. Taking it in BEDROCK would force the protocol to sell its own token to fund its own floor. It never does.
Selling BEDROCK costs nothing beyond gas.
| You send | 1.0000 |
|---|---|
| Goes into the curve and comes back as your BEDROCK | 0.9700 |
| Fee | 0.0300 |
| Refusal reserve, then The Refusal | 0.0150 |
| Core reserve, then buyback and staged liquidity | 0.0150 |
Each core takes a quarter of the core reserve. Up to half a percent of that pays whoever triggered it. Of the rest, 40% is staged as liquidity under the price and 60% buys BEDROCK back. Every BEDROCK bought back is sent to the dead address.
These amounts are asserted to the wei in the contract test suite, for both exact-input and exact-output buys, including swaps routed through the Uniswap Universal Router on a mainnet fork.
On-chain history
Every core emits one event with everything needed to rebuild its history: the tick before and after, the ETH spent, the ETH staged back under the price, and the BEDROCK taken out of circulation.
This page reads those events straight from Ethereum. Nothing here comes from a Bedrock server.
Reading the log from the chain…
Read this first
A protocol that hides its limits gets judged on them the first time they show up. These are Bedrock's.
Bounded in the contract
Every changeable value is bounded inside the contract, checked when it is set, and delayed by two days so anyone can react before it applies. Ownership will be renounced once the values are calibrated in production; the date is announced at launch. After that, nothing on this list can change.
| Parameter | On-chain | Hard bound | Who can change it |
|---|---|---|---|
| Buy fee | 3.00% | 2.00% to 5.00% | Owner, after a 2-day timelock |
| Sell fee | 0% | at most 5.00% | Owner, after a 2-day timelock |
| Share of the fee to The Refusal | 50% | 20% to 80% | Owner, after a 2-day timelock |
| Core size, share of the core reserve | 25% | 5% to 100% | Owner, after a 2-day timelock |
| Share of a core staged as liquidity | 40% | at most 80% | Owner, after a 2-day timelock |
| Keeper bounty | 0.50%, capped | at most 2.00%, cap at most 1 ETH | Owner, after a 2-day timelock |
| Largest price move a core can cause | 2.00% | fixed | Nobody |
| Interval between cores | 0 to 10 min, random | fixed | Nobody |
| Smallest core | set by simulation | fixed | Nobody |
| Largest core | set by simulation | fixed | Nobody |
| Withdraw protocol liquidity or reserves | impossible | no code path | Nobody |
