Functions

func EncodeMsgsIntoTxBytes 

func EncodeMsgsIntoTxBytes(txConfig client.TxConfig, msgs ...sdk.Msg) ([]byte, error)

EncodeMsgsIntoTxBytes encodes the given msgs into a single transaction.

func FullNodePrepareProposalHandler 

func FullNodePrepareProposalHandler() sdk.PrepareProposalHandler

FullNodePrepareProposalHandler returns an EmptyResponse and logs an error if a node running in `--non-validating-full-node` mode attempts to run PrepareProposal.

func GetGroupMsgOther 

func GetGroupMsgOther(availableTxs [][]byte, maxBytes int64) ([][]byte, [][]byte)

GetGroupMsgOther returns two separate slices of byte txs given a single slice of byte txs and max bytes. The first slice contains the first N txs where the total bytes of the N txs is <= max bytes. The second slice contains the rest of txs, if any.

func PrepareProposalHandler 

func PrepareProposalHandler(
	txConfig client.TxConfig,
	bridgeKeeper PrepareBridgeKeeper,
	clobKeeper PrepareClobKeeper,
	pricesKeeper PreparePricesKeeper,
	perpetualKeeper PreparePerpetualsKeeper,
) sdk.PrepareProposalHandler

PrepareProposalHandler is responsible for preparing a block proposal that's returned to Tendermint via ABCI++.

The returned txs are gathered in the following way to fit within the given request's max bytes:

  • "Fixed" Group: Bytes=unbound. Includes price updates and premium votes.
  • "Others" Group: Bytes=25% of max bytes minus "Fixed" Group size. Includes txs in the request.
  • "Order" Group: Bytes=75% of max bytes minus "Fixed" Group size. Includes order matches.
  • If there are extra available bytes and there are more txs in "Other" group, add more txs from this group.

func RemoveDisallowMsgs 

func RemoveDisallowMsgs(ctx sdk.Context, decoder sdk.TxDecoder, txs [][]byte) [][]byte

RemoveDisallowMsgs removes any txs that contain a disallowed msg.

Types

) BridgeTxResponse

GetAcknowledgeBridgeTx returns a tx containing a list of `MsgAcknowledgeBridge`. The response contains an error if encoding fails.

type FundingTxResponse 

type FundingTxResponse struct {
	Tx       []byte
	Err      error
	NumVotes int
}

FundingTxResponse represents a response for creating `AddPremiumVotes` tx.

func GetAddPremiumVotesTx 

func GetAddPremiumVotesTx(
	ctx sdk.Context,
	txConfig client.TxConfig,
	perpetualsKeeper PreparePerpetualsKeeper,
) FundingTxResponse

GetAddPremiumVotesTx returns a tx containing `MsgAddPremiumVotes`. The response contains an error if encoding fails.

type OperationsTxResponse 

type OperationsTxResponse struct {
	Tx            []byte
	Err           error
	NumOperations int
}

OperationTxResponse represents a response for creating 'ProposedOperations' tx

func GetProposedOperationsTx 

func GetProposedOperationsTx(
	ctx sdk.Context,
	txConfig client.TxConfig,
	clobKeeper PrepareClobKeeper,
) OperationsTxResponse

GetProposedOperationsTx returns a tx containing `MsgProposedOperations`. The response contains an error if encoding fails.

type PrepareBridgeKeeper 

type PrepareBridgeKeeper interface {
	GetAcknowledgeBridges(ctx sdk.Context, blockTimestamp time.Time) *bridgetypes.MsgAcknowledgeBridges
}

PrepareBridgeKeeper defines the expected Bridge keeper used for `PrepareProposal`.

type PrepareClobKeeper 

type PrepareClobKeeper interface {
	GetOperations(ctx sdk.Context) *clobtypes.MsgProposedOperations
}

PrepareClobKeeper defines the expected CLOB keeper used for `PrepareProposal`.

type PreparePerpetualsKeeper 

type PreparePerpetualsKeeper interface {
	GetAddPremiumVotes(ctx sdk.Context) *perpstypes.MsgAddPremiumVotes
}

PreparePerpetualsKeeper defines the expected Perpetuals keeper used for `PrepareProposal`.

type PreparePricesKeeper 

type PreparePricesKeeper interface {

type PrepareProposalTxs 

type PrepareProposalTxs struct {
	// Transactions.
	UpdateMarketPricesTx []byte
	AddPremiumVotesTx    []byte
	ProposedOperationsTx []byte
	AcknowledgeBridgesTx []byte
	OtherTxs             [][]byte

	// Bytes.
	// In general, there's no need to check for int64 overflow given that it would require
	// exabytes of memory to hit the max int64 value in bytes.
	MaxBytes  int64
	UsedBytes int64
}

PrepareProposalTxs is used as an intermediary storage for transactions when creating a proposal for `PrepareProposal`.
