**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*](/classic-sdk/classes/_entities_transactionqueue_.transactionqueue.md)*‹Args, ReturnType››*

*Inherited from void*

*Defined in* [*src/procedures/Procedure.ts:52*](https://github.com/PolymathNetwork/polymath-sdk/blob/e8bbc1e/src/procedures/Procedure.ts#L52)

Mandatory method that builds a list of transactions that will be run

**Returns:** *Promise‹*[*TransactionQueue*](/classic-sdk/classes/_entities_transactionqueue_.transactionqueue.md)*‹Args, ReturnType››*

### prepareTransactions

▸ **prepareTransactions**(): *Promise‹void›*

*Overrides void*

*Defined in* [*src/procedures/InvestInSimpleSto.ts:56*](https://github.com/PolymathNetwork/polymath-sdk/blob/e8bbc1e/src/procedures/InvestInSimpleSto.ts#L56)

Buy Security Tokens from the STO

Note that this procedure will fail if:

* The Security Token doesn't exist
* The STO address is invalid
* The STO is either archived or hasn't been launched
* The STO hasn't started yet
* The STO is paused
* The STO has already been finalized
* Attempting to invest on behalf of another address when beneficial investments aren't allowed for the STO
