💡 This contract is for educational purposes only. It has not been audited. Introduction In this blog post, we'll explore how to write a venture funding smart contract in Algorand Python. The aim is to provide a secure way for investors to pledge s...

I assume calling arc4.abi_call for VaultFactory.new method implies that the VaultFactory had been deployed prior to the call and minimum balance requirements are satisfied?

I believe it's creating a new contract on the fly. The 'vault factory' contract is ephemeral in a way... a new contract is deployed whenever the method is called, and then it's deleted in the same transaction group. The contract account remains even after the application is deleted.

I think that's why you have to supply the compiled TEAL approval program and clear state programs. There's no existing application on the chain that gets called... it's creating a new one from scratch each time.

I think the reference to VaultFactory.new probably just provides the the information for the ABI call (the method signature to use for encoding and decoding).

As I understand it, the minimum balance requirement only needs to be satisfied by the end of the transaction group.

The act of creating a vault and rekeying it is all done with inner transactions.

Hope that makes sense...

Alexander Codes So it's kind of like:

Outer:

Application Call (pledge method)

Inner:

Deploy vault factory
(inner rekey to sender & return the address)
Delete vault factory contract
Fund vault account

Thank you for this, Alex. Top quality as usual! Special thanks for Python idiosyncrasies explanation (e.g. falsey in find_vault method)

Set up your NFD wallet asap )

I've just set it up, it's alexandercodes.algo :)
