Methods
addProcedure
▸ addProcedure<A, R>(Proc: ProcedureClass‹A, R›): (Anonymous function)
Inherited from void
Defined in src/procedures/Procedure.ts:91
Appends a Procedure into the TransactionQueue's queue. This defines what will be run by the TransactionQueue when it is started.
Type parameters:
▪ A
▪ R: any
Parameters:
Name | Type | Description |
| ProcedureClass‹A, R› | A Procedure that will be run in the Procedure's TransactionQueue |
Returns: (Anonymous function)
whichever value is returned by the Procedure
addSignatureRequest
▸ addSignatureRequest<A>(request: SignatureRequest‹A›): (Anonymous function)
Inherited from void
Defined in src/procedures/Procedure.ts:179
Appends a signature request into the TransactionQueue's queue. This defines what will be run by the TransactionQueue when it is started.
Type parameters:
▪ A
Parameters:
Name | Type | Description |
| A signature request that will be run in the Procedure's TransactionQueue |
Returns: (Anonymous function)
a PostTransactionResolver that resolves to the signed data
addTransaction
▸ addTransaction<A, R, V>(method: LowLevelMethod‹A› | FutureLowLevelMethod‹V, A›, __namedParameters: object): (Anonymous function)
Inherited from void
Defined in src/procedures/Procedure.ts:137
Appends a method or future method into the TransactionQueue's queue. This defines what will be run by the TransactionQueue when it is started.
Type parameters:
▪ A
▪ R: any[]
▪ V: any
Parameters:
▪ method: LowLevelMethod‹A› | FutureLowLevelMethod‹V, A›
A method (or future method) that will be run in the Procedure's TransactionQueue. A future method is a transaction that doesn't exist at prepare time (for example a transaction on a module that hasn't been attached but will be by the time the previous transactions are run)
▪Default value __namedParameters: object= {}
Returns: (Anonymous function)
a PostTransactionResolver that resolves to the value returned by the resolver function, or undefined if no resolver function was passed
prepare
▸ prepare(): Promise‹TransactionQueue‹Args, ReturnType››
Inherited from void
Defined in src/procedures/Procedure.ts:52
Mandatory method that builds a list of transactions that will be run
Returns: Promise‹TransactionQueue‹Args, ReturnType››
prepareTransactions
▸ prepareTransactions(): Promise‹void›
Overrides void
Defined in src/procedures/ApproveErc20.ts:21
Approve spend of an ERC20 token by another wallet. The token in question defaults to POLY if no address is supplied
Note that if the amount has already been approved, the spending approval transaction will not be added to the queue and the procedure will return
Note that the procedure will fail if the owner's token balance is less than the amount being approved. The only exception to this is when approving a POLY spend on a testnet. If that is the case, an extra transaction will be submitted to request the missing amount of tokens from the faucet
Returns: Promise‹void›
