Bridge

Bridge Overview

The StonkBrokerChain bridge is the canonical rollup bridge — the same trust-minimized mechanism Arbitrum One uses, not a third-party token bridge. $STONKBROKER locked on Robinhood Chain is provably backed 1:1 by native $STONKBROKER on StonkBrokerChain.

How it flows

        DEPOSIT (~1 minute)
Robinhood Chain ──── lock STONKBROKER in bridge ────▶ StonkBrokerChain
   (ERC-20)                                       (native coin)

        WITHDRAW (minutes)
StonkBrokerChain ──── burn native STONKBROKER ────▶ Robinhood Chain
  (native coin)      prove & release                (ERC-20)

Deposit — approve, then deposit the ERC-20 into the bridge inbox on Robinhood Chain. The same amount is credited to the same address on StonkBrokerChain as native $STONKBROKER.
Withdraw — send native $STONKBROKER to the ArbSys withdrawal precompile. Once the validator confirms the state, the tokens are released from the bridge on Robinhood Chain.

Speed

Robinhood Chain → StonkBrokerChain	~1 minute
StonkBrokerChain → Robinhood Chain	minutes — not the multi-day wait of classic optimistic rollups

Withdrawals are fast because the chain runs fast confirmation: the validator finalizes state assertions immediately instead of waiting out a long challenge window. See Fast Finality for the trade-off.

Amounts and decimals

$STONKBROKER has 18 decimals on both sides, so amounts map 1:1 — bridge 100, receive 100. The bridge itself charges nothing; you pay only network gas (ETH on Robinhood Chain for deposits, $STONKBROKER on StonkBrokerChain to initiate withdrawals).
