Chain basics
How do I use the Robinhood Chain testnet?
The Robinhood Chain testnet is chain ID 46630, with RPC at https://rpc.testnet.chain.robinhood.com and a block explorer at explorer.testnet.chain.robinhood.com. It uses ETH for gas, like mainnet.
The testnet mirrors mainnet's Nitro configuration, so contract behaviour, gas semantics and the Arbitrum-specific transaction types are identical. Anything that works on testnet will behave the same way on chain 4663.
Be aware that stock tokens on testnet do not track real corporate actions. If you are testing multiplier handling, you will need to simulate multiplier updates rather than wait for a real split.
