The mint this transaction represents, if applicable
Methods
eraseProofs()
eraseProofs(): ProofErasedTransaction
Erases the proofs contained in this transaction
Returns
fees()
fees(params): bigint
The cost of this transaction, in the atomic unit of the base token
Parameters
params
Returns
bigint
identifiers()
identifiers(): string[]
Returns the set of identifiers contained within this transaction. Any of these may be used to watch for a specific transaction.
Returns
string[]
imbalances()
imbalances(guaranteed, fees?): Map<string, bigint>
For given fees, and a given section (guaranteed/fallible), what the surplus or deficit of this transaction in any token type is.
Parameters
guaranteed
boolean
fees?
bigint
Returns
Map<string, bigint>
merge()
merge(other): Transaction
Merges this transaction with another
Parameters
other
Returns
Throws
If both transactions have contract interactions, or they spend the same coins
serialize()
serialize(netid): Uint8Array<ArrayBufferLike>
Parameters
netid
Returns
Uint8Array<ArrayBufferLike>
toString()
toString(compact?): string
Parameters
compact?
boolean
Returns
string
transactionHash()
transactionHash(): string
Returns the hash associated with this transaction. Due to the ability to merge transactions, this should not be used to watch for a specific transaction.

string
deserialize()
static deserialize(raw, netid): Transaction
Parameters
raw
Uint8Array<ArrayBufferLike>
netid
Returns
fromUnproven()
static fromUnproven(prove, unproven): Promise<Transaction>

Parameters
prove
(unproven) => Promise<Transaction>
unproven
