C3 Bounty - Single Transaction Deposit

Overview

Short Description: The objective of this bounty is to develop the creation of a deposit operation of Algos/ASAs to a smart contract using a single transaction.
Bounty: 5000 ALGO tokens (US residents will receive USDCa and have to opt-in to receive the asset in their wallet)
Estimated Time Commitment: 2 Weeks (For the following info, please also add the according labels to the issue)
Category: Development
Experience Level: Beginner / Intermediate
Mode: Traditional

Description

What is this task?

How deposit works now:

User compiles a payment/asset transfer transaction of the desired amount
User compiles an deposit app call transaction
User group them, signs them once they are grouped, sends them
Contract verifies that the group is coherent (i.e.: by checking that the sender is the same, the receiver is the address of the contract, by reading the deposited amount in the first txn, ...)
Approves

Possible solution (developers can use this solution but we will value other ideas and if you use this solution we will value the minimal user security exposure) using rekey feature:

User compiles a deposit app call transaction and sets the rekeyTo (LINK: https://developer.algorand.org/docs/get-details/transactions/transactions/#common-fields-header-and-type) field to the address of the contract
Contract checks that the rekey is valid (i.e.: is set to the address of the contract) and reads the desired asset / amount
Contract compiles an inner payment/asset transfer transaction from the user's address to the contract's address because it is allowed to by the previous rekeyTo. It also gives back authority over the user's address to the user's private key by setting the rekeyTo field to the original user.
This is the trickiest bit because we want to rekey the user address (that is currently in our authority) and not the contract address (not sure if that's possible. This topic definitely deserves more research)
Approves

Hi, I have been keeping an eye on Algo for some time already and decided this bounty would be a great motivation to finally dive in. I hope to prepare before the hackathon starts and provide a robust solution. Fingers crossed! 2) algido has started work.

Will write smart contract examples for a few variations of the deposit transaction, accompanied by the Typescript code (ts-node) needed to run them. 3) algodoggo has started work.

Hello, I will write the contracts in TEAL if you don't mind. I find it safer / easier to debug. 4) jackchina11 has started work.

@marcosnc Hey I submitted work in this repo https://github.com/algido/single-transaction-deposit. It contains the PyTeal smart contract code, as well as the ts-node scripts needed to deploy the application and make a deposit transaction. The deposit transaction rekeys to the application address, creates an inner transaction and then rekeys back.
