Authorization

Field	Type	Label	Description
terms	MsgCreateAuthorization
consumed	bool
revoked	bool
used_from	string
expire_height	uint64		expire_height is the absolute block height after which the authorization is rejected and pruned. Zero is invalid for new records.
attempted	bool		attempted records that a holder-funded execution was already attempted. It is stored with the authorization so genesis export/import keeps the no-retry guarantee.

ClaimMarker

ClaimMarker is the genesis form of a claim replay marker: either a spent nonce (revoked=false) or an explicitly revoked nonce (revoked=true).

Field	Type	Label	Description
signer	string
nonce	bytes
expiry_height	uint64
revoked	bool

QueryAuthorizationRequest

Field	Type	Label	Description
holder	string
order_seq	uint64

QueryAuthorizationResponse

Field	Type	Label	Description
authorization	Authorization
high_water_mark	uint64

QueryAuthorizationsRequest

QueryAuthorizationsRequest lists every authorization created by a holder, newest sequence last. Consumed and revoked authorizations are included.

Field	Type	Label	Description
holder	string
pagination	cosmos.base.query.v1beta1.PageRequest

QueryAuthorizationsResponse

Field	Type	Label	Description
authorizations	Authorization	repeated
pagination	cosmos.base.query.v1beta1.PageResponse

QueryHighWaterMarkRequest

Field	Type	Label	Description
holder	string

QueryHighWaterMarkResponse

Field	Type	Label	Description
sequence	uint64

SwapGenesis

Field	Type	Label	Description
config	SwapConfig
authorizations	Authorization	repeated
high_water_marks	SwapHighWaterMark	repeated
claim_markers	ClaimMarker	repeated	claim_markers preserves the single-tx permit replay state across genesis export/import. Expired markers are not exported.

double		double	double	float	float64	double	float	Float
float		float	float	float	float32	float	float	Float
int32	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int64	long	int/long	int64	long	integer/string	Bignum
uint32	Uses variable-length encoding.	uint32	int	int/long	uint32	uint	integer	Bignum or Fixnum (as required)
uint64	Uses variable-length encoding.	uint64	long	int/long	uint64	ulong	integer/string	Bignum or Fixnum (as required)
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
