Bridge
Withdraw
Move $STONKBROKER from StonkBrokerChain back to Robinhood Chain. It settles in minutes thanks to fast confirmation, in three stages.
What you need
- Native $STONKBROKER on StonkBrokerChain — a bit more than the withdrawal amount, for gas
- A little ETH on Robinhood Chain for the final claim transaction
- Your wallet connected to StonkBrokerChain to start
The three stages
- 1Initiate (child chain, instant) — the bridge sends your $STONKBROKER to the
ArbSyswithdrawal precompile. Your native balance drops immediately. - 2Confirmation (automatic, minutes) — the validator posts and fast-confirms a state assertion covering your withdrawal on Robinhood Chain.
- 3Claim (Robinhood Chain, one transaction) — execute the withdrawal against the bridge
Outbox. The ERC-20 is released to your address.
Under the hood
- Initiation calls
ArbSys.withdrawEth(destination)at the fixed precompile0x…0064, with the amount as native value. withdrawEth is the Nitro precompile name — on this chain it withdraws the native coin, which is $STONKBROKER. - The claim calls
executeTransaction(...)on theOutboxon Robinhood Chain with a Merkle proof. Anyone can submit the claim; funds always go to the withdrawal’s destination address.
Troubleshooting
- Claim reverts right after initiating — the assertion covering your withdrawal has not confirmed yet. Wait a couple of minutes; the proof root must be registered in the Outbox first.
- Cannot pay for the claim — the claim is a Robinhood Chain transaction paid in ETH there. Keep a small ETH balance.
