type ClobDecorator ¶

type ClobDecorator struct {
	// contains filtered or unexported fields
}

ClobDecorator is an AnteDecorator which is responsible for:

• adding short term order placements and cancelations to the in-memory orderbook (`CheckTx` only).
• adding stateful order placements and cancelations to state (`CheckTx` and `RecheckTx` only).

This AnteDecorator also enforces that any Transaction which contains a `MsgPlaceOrder`, or a `MsgCancelOrder`, must consist only of a single message.

This AnteDecorator is a no-op if:

• No messages in the transaction are `MsgPlaceOrder` or `MsgCancelOrder`.
• This AnteDecorator is called during `DeliverTx`.

This AnteDecorator returns an error if:

• The transaction contains multiple messages, and one of them is a `MsgPlaceOrder` or `MsgCancelOrder` message.
• The underlying `PlaceStatefulOrder`, `PlaceShortTermOrder`, `CancelStatefulOrder`, or `CancelShortTermOrder` methods on the keeper return errors.

	next sdk.AnteHandler,
) (sdk.Context, error)

type ClobRateLimitDecorator ¶

type ClobRateLimitDecorator struct {
	// contains filtered or unexported fields
}

ClobRateLimitDecorator is an AnteDecorator which is responsible for rate limiting MsgCancelOrder and MsgPlaceOrder requests.

This AnteDecorator is a no-op if:

• No messages in the transaction are `MsgCancelOrder` or `MsgPlaceOrder`.

This AnteDecorator returns an error if:

• The rate limit is exceeded for any `MsgCancelOrder` messages.
• The rate limit is exceeded for any `MsgPlaceOrder` messages.

TODO(CLOB-721): Rate limit short term order cancellations.

) (newCtx sdktypes.Context, err error)

type ShortTermSingleMsgClobTxAnteWrapper ¶

type ShortTermSingleMsgClobTxAnteWrapper struct {
	// contains filtered or unexported fields
}

ShortTermSingleMsgClobTxAnteWrapper is a wrapper for Antehandlers that need to be skipped for single msg clob txs `MsgPlaceOrder` and `MsgCancelOrder` which reference Short-Term orders. For example, these transactions do not require sequence number validation.

func NewShortTermSingleMsgClobTxAnteWrapper(handler sdk.AnteDecorator) ShortTermSingleMsgClobTxAnteWrapper

func (anteWrapper ShortTermSingleMsgClobTxAnteWrapper) AnteHandle(
	ctx sdk.Context,
	tx sdk.Tx,
	simulate bool,
	next sdk.AnteHandler,
) (sdk.Context, error)

func (antWrapper ShortTermSingleMsgClobTxAnteWrapper) GetAnteHandler() sdk.AnteDecorator

type SingleMsgClobTxAnteWrapper ¶

type SingleMsgClobTxAnteWrapper struct {
	// contains filtered or unexported fields
}

SingleMsgClobTxAnteWrapper is a wrapper for Antehandlers that need to be skipped for single msg clob txs `MsgPlaceOrder` and `MsgCancelOrder`. These transactions should always have `0` Gas, and therefore should never be charged a gas fee.

func NewSingleMsgClobTxAnteWrapper(handler sdk.AnteDecorator) SingleMsgClobTxAnteWrapper

func (anteWrapper SingleMsgClobTxAnteWrapper) AnteHandle(
	ctx sdk.Context,
	tx sdk.Tx,
	simulate bool,
	next sdk.AnteHandler,
) (sdk.Context, error)

func (antWrapper SingleMsgClobTxAnteWrapper) GetAnteHandler() sdk.AnteDecorator
