Does Flashbots support Arbitrum,BSC?

I hope to use flashbots on Arbitrum layer2 of eth. Does it work out? What should I do to support this? Or Binance smart chain?

Hi, welcome to the forum! :wave:

The Flashbots products are only available on the Ethereum L1.

Hi, so the repo simple-arbitrage too, only runs on Ethereum L1?

if so, is there a cheaper way to play with demo code: simple-arbitrage ?
Testing it on L1 is too expensive now.

MEV relays are also exists on Goerli and Sepolia testnet.
