func IsArbTxLoose ¶

func IsArbTxLoose(tx sdk.Tx) bool

We check if a tx is an arbitrage for the mempool right now by seeing: 1) does start token of a msg = final token of msg (definitionally correct) 2) does it have multiple swap messages, with different tx ins. If so, we assume its an arb.

• This has false positives, but is intended to avoid the obvious solution of splitting an arb into multiple messages.

3) We record all denoms seen across all swaps, and see if any duplicates. (TODO) 4) Contains both JoinPool and ExitPool messages in one tx.

• Has some false positives, but they seem relatively contrived.

TODO: Move the first component to a future router module.
