Functions

func FullNodeProcessProposalHandler 

func FullNodeProcessProposalHandler(
	txConfig client.TxConfig,
	bridgeKeeepr ProcessBridgeKeeper,
	clobKeeper ProcessClobKeeper,
	stakingKeeper ProcessStakingKeeper,
	perpetualKeeper ProcessPerpetualKeeper,
	pricesKeeper ProcessPricesKeeper,
) sdk.ProcessProposalHandler

FullNodeProcessProposalHandler is the `ProcessProposal` implementation for full-nodes. This implementation calculates and reports MEV metrics and always returns `abci.ResponseProcessProposal_ACCEPT`. Validators within the validator set should never use this implementation.

func GetAppInjectedMsgIdxMaps 

func GetAppInjectedMsgIdxMaps(numTxs int) (map[txtype]int, map[int]txtype)

GetAppInjectedMsgIdxMaps returns two maps. The first map is `txtype` to the index where that particular `txtype` msg can be found in the block proposal's list of txs. The second map is the reverse of the first map.

func ProcessProposalHandler 

func ProcessProposalHandler(
	txConfig client.TxConfig,
	bridgeKeeper ProcessBridgeKeeper,
	clobKeeper ProcessClobKeeper,
	stakingKeeper ProcessStakingKeeper,
	perpetualKeeper ProcessPerpetualKeeper,
	pricesKeeper ProcessPricesKeeper,
) sdk.ProcessProposalHandler

ProcessProposalHandler is responsible for ensuring that the list of txs in the proposed block are valid. Specifically, this validates:

  • Tx bytes can be decoded to a valid tx.
  • Txs are ordered correctly.
  • Required "app-injected message" txs are included.
  • No duplicate "app-injected message" txs are present (i.e. no "app-injected msg" in "other" txs).
  • All messages are "valid" (i.e. `Msg.ValidateBasic` does not return errors).
  • All proposed prices within `MsgUpdateMarketPrices` are valid according to non-deterministic validation.

Note: `MsgUpdateMarketPrices` is an exception to only doing stateless validation. In order for this msg to be valid, the proposed price update values are compared against the local index price. Because the outcome depends on the local index price, this validation is dependent on "in-memory state"; therefore, this check is NOT stateless. Note: stakingKeeper and perpetualKeeper are only needed for MEV calculations.
