RWA and ERC-20 quotes
Read what changes in a Hookr pool when the quote asset is not native ETH, and what a tokenized stock brings along with it.
Every rule works on every quote currency. This page covers what changes when the quote is not native ETH, and what to know before pairing a tokenized stock.
ERC-20 Quotes
The claim ledger is keyed by quote currency, so a native-quoted pool and an ERC-20-quoted pool share the module without their balances ever crossing. claim, claimTo, collect and accountingInvariant all take the quote address, with address(0) meaning native.
Four things differ from a native quote:
Payment. openNewTokenMarket and openExistingTokenMarket require msg.value == 0 when quote != address(0), and revert InvalidPayment(expected, received) otherwise. The coordinator itself pulls no quote on either lane: quoteAmount must be zero, and the only quote that moves at launch is the creator buy, which the router pulls (next paragraph).
The creator buy. For an ERC-20 quote the creator approves the Hookr router for the quote token before launching. The launch reverts otherwise.
The pot floor. A native quote uses the fixed MIN_POT_BUY_WEI = 0.001 ether. An ERC-20 quote must set potMinBuyWei to at least 10 ** (decimals - 3), one thousandth of one whole unit. Admission enforces this with a gas-bounded decimals() read and rejects a token whose decimals are below 3 or above MAX_QUOTE_DECIMALS = 36, or whose decimals() call fails. USDG has six decimals, so its floor is 1,000 base units.
Transfer behaviour. The coordinator and the module both compare balances before and after every ERC-20 movement; the coordinator reverts TaxedTransfer on a mismatch and the module reverts ClaimTransferFailed. A fee-on-transfer or rebasing quote will not work as a Hookr quote currency.
Robinhood Tokenized Stocks
A Robinhood stock token on chain 4663 is a BeaconProxy over a shared Stock implementation. Four properties matter to anyone integrating a pool that holds one.
A shared pause and blocklist registry. Pause and blocklist state lives in one chain-wide contract, not per token: 0xe10b6f6B275de231345c20D14Ab812db62151b00. The ERC-1967 beacon slot of both NFLX and AAPL holds that address, and it answers implementation() and isBlocked(address), so the same contract carries the implementation pointer and the access state. A pause halts transfers of that token, which halts every pool holding it. This is fail-closed: swaps revert rather than settling at a stale price.
A blocklist. The implementation checks from, to and spender. A blocked address cannot trade the pool, and a pool whose hook or router is blocked stops working for everyone.
adminBurn. A privileged role can burn a holder's balance. The supply a Hookr pool prices against is not fixed by the token's own contract.
ERC-8056 uiMultiplier. Corporate actions change a display multiplier. It changes what an interface should show. It does not change pool math, tick spacing, or any Hookr rule.
Combinations to Warn On
The contract permits all of these. The judgment is the integrator's.
| Combination | Why it needs a warning |
|---|---|
| Burn with a tokenized stock as subject | Every buy destroys a claim on a real share. |
| Burn with a stablecoin as subject | Every buy destroys a unit of the peg. |
| Burn with any subject the creator does not control | If the token blocks the transfer to 0x...dEaD, every buy reverts and the pool fails closed. Test one buy before launching. |
| Any pool holding a stock on either side | A pause of that token halts this pool. Corporate actions change the displayed multiplier, not the pool math. |
| Pot or LP reward with a stock as quote | Payouts and donations are denominated in shares. |
| Subject is HOOKR with burn enabled | Allowed and coherent. Every buy burns HOOKR. |
Two combinations the contract rejects outright: subject equal to quote, and a guard window on the existing-asset lane.
What the Hook Does Not Add
There is no stock-specific code path. A market pairing a tokenized stock satisfies the same StackLimits preconditions as any other market: the trusted router and quoter must be registered integrations, and maxLpFeePips must cover the base fee plus the surge cap. The properties above come from the token, not from the hook.
