Robinhood Chain
Chain ID 4663, public RPC, Blockscout, and why Flips is single-chain.
Flips trades on Robinhood Chain only. That is an Arbitrum Orbit L2. Chain ID 4663. Native gas token is ETH.
Add the network
- Chain ID:
4663 - RPC:
https://rpc.mainnet.chain.robinhood.com(public, rate-limited) - Explorer: robinhoodchain.blockscout.com
A linked browser wallet that is still on Ethereum mainnet will not send a Flips ticket. Switch the wallet, do not paste the 4663 address into a mainnet send modal and hope.
Block time
Blocks are on the order of 0.1s. Windowed stats (5m, 1h) are a lot of blocks. If a chart looks "empty," it may be a query window, not zero flow.
Testnet
Chain ID 46630 exists. The production terminal is mainnet 4663. Do not deposit real size to a testnet address because a faucet page looked similar.
Bridges
In and out of 4663 go through Deposit & withdraw, not through a random L2 bridge UI that does not list Robinhood Chain.
