# Chains

> BaseStonk runs on Base and on Robinhood Chain. What is the same, what is different, and why.

BaseStonk is one venue on two chains. A launch is a live Uniswap v4 pool
from its first block on both; the fee hook, the launcher's no-custody
rule and the holder-dividend mechanics are the same contracts on both.
What differs is what a token can be priced in, and where the platform's
cut goes.

Switch chains from the header. The token list, the create form and your
portfolio follow it, and a wallet on the wrong network is asked to switch
before it can sign.

## Robinhood Stock Tokens as pairs

Robinhood issues 194 tokenized equities and ETFs on its chain - NVIDIA,
Apple, Tesla, the S\&P 500, and so on - and every one of them is
launchable against, subject to one gate.

<Note>
  **Admission is a predicate, not a list.** A pair is admitted if it is a
  genuine Robinhood Stock Token - the registry checks the issuer's proxy
  bytecode and a non-zero supply - or USDG or WETH. There is no allowlist to
  be on. A ticker Robinhood issues tomorrow is launchable the moment it has
  supply.
</Note>

The gate is depth. Before a launch opens, the registry measures the cost
of pushing the pair's own price down ten times through its deepest
market, and refuses any pair where that costs under **\$1,000**. It is a
test of whether the pair's market is real, not of whether the price is
precise: the failure the gate exists to prevent is a launch opening at a
market cap that was never there. At today's depth roughly half of the 194
clear it, and the create form only offers the ones that do.

Pricing comes from Chainlink where a feed exists and from the pair's own
market otherwise, read at the moment you sign. Never typed in.

## Where the platform's cut goes

On Base, the platform's share of every trade is converted to \$BSTONK
and burnt - the [second flywheel](/bstonk).

On Robinhood Chain it is not. **The platform's cut converts to USDG and
is held in the venue's fee vault on 4663.** Nothing bridges to Base
automatically, and \$BSTONK does not exist on Robinhood Chain. This is a
deliberate choice, not a gap waiting to be closed: \$BSTONK stays a Base
token, and moving value between chains is a decision the operator makes
by hand, never a pipe.

Two things follow for a launch on Robinhood Chain:

* **There is no \$BSTONK basket seat.** The slice of the creator's half
  that on Base feeds the platform basket does not exist here. A creator's
  half goes to their payees and to holder dividends, and that is the whole
  split.
* **Holder dividends are paid in the pair.** A token paired with USDG
  pays holders in USDG; a token paired with NVDA pays in NVDA. The
  [dividend basket](/dividend-baskets) can route them into other
  Robinhood assets, as on Base.

## Fees

Identical arithmetic. The platform takes `min(half the trade's rate, 1%)`
and the creator controls the rest - see [Fees](/fees). The only
difference is the destination of the platform's share, above.

## For builders

The REST API takes `chain=robinhood` wherever it takes `chain=base`;
every indexed surface - tokens, candles, trades, holders, rewards, stats -
answers for both. The [agent API](/integration/agents) prepares launches
and trades on either chain: send `chainId: 4663` in the body and the
unsigned transaction comes back for `RhLauncher` or the Robinhood router,
with the same verdict shape. The [contract reference](/integration/contracts) lists
the Robinhood Chain addresses, and the [on-chain page](/integration/onchain)
carries the launch tuple, which is narrower than Base's V6 tuple in one
respect: it has no `vaultShareBps`, `issuers` or `renounceBasket`,
because the basket seat it would describe does not exist there.

<Warning>
  Robinhood Chain produces a block every **0.1 seconds** - roughly forty
  times Base's rate. An indexer that scans by block range will see
  864,000 blocks a day. Filter `eth_getLogs` by address or topic; a wide
  unfiltered range is refused by every public endpoint on the chain.
</Warning>

## What is not on Robinhood Chain

* \$BSTONK, its buyback, and the platform basket vault. These are Base.
* Referral links. A referral is created by holding USDC on Base, and
  pays out there.
* B20 mode. B20 tokens are a Coinbase standard issued on Base.
* The Clanker, Virtuals and Bankr ecosystem pairs. Those catalogues are
  Base-native; Robinhood Chain's equivalent rail is the 194 equities.
