Ethereum MEV capabilities

[douglasgalico]

In order to support Flashbots / MEV-Share , there are some endpoints that can be integrated to near-ca in order to make them works from near-ca:

• eth_callBundle - for simulation
• mev_simBundle - for simulation using MEV-Share new bundle spec
• mev_sendBundle - for MEV-Share submission
• eth_sendBundle - for Flashbots integration (older bundle format)
• eth_sendPrivateTransaction - Submitting into private mempool
• eth_sendPrivateRawTransaction - Submitting raw transaction to private mempool.

To think: cancel endpoints are needed from near-ca ?

Also expanding ethereum to some L2s , can other private mempools be supported as well? Like Merkle for Base and FastLane for Polygon? (Maybe also Jito for Solana in future)

Shouldn't forget MEV Blocker

One thing to note is that this library's CLI capabilities are not really the primary use case. This is intended to be a library for other front ends and is also the primary dependency of Near Safe: https://github.com/BitteProtocol/near-safe

So the front end user of this library rarely calls "eth_sendRawTransaction" to a public mempool, but rather sends to whatever RPC they want.
