Rekey account assignment

You are given 3 accounts - A, B and C. Rekey account A to a MultiSig account. The MultiSig account should contain B and C and have a threshold of 1. Once account A is rekeyed, use it to send 100,000 microAlgos (or 0.1 Algos) to account B.

Write your solution in the skeleton code provided in rekey.js.

Setup instructions

1. Install packages with npm install.
2. Copy .env.example to .env.
3. Update Algorand Sandbox credentials in .env file.
4. Use variables from .env file by running source .env.

Running your script

2. Run your script with node rekey.js.

Key points to remember

1. Accounts need to maintain a minimum balance of 100,000 microAlgos to carry out transactions.
2. Transactions sent from a rekeyed account needs to be signed off by the authorising account.
3. A MultiSig account with a threshold of 1 means that either B or C can sign off.

Hints

These are the javascript SDK functions needed to carry out transactions. Refer to the documentation for more details.

// get suggested params for transactions
let params = await algodClient.getTransactionParams().do();

// create a payment transaction
let txn = algosdk.makePaymentTxnWithSuggestedParams(...);

// sign a transaction
let signedTxn = txn.signTxn(...);

// create a multisig account
let multsigaddr = algosdk.multisigAddress(...);

// sign a multisig transaction
let signedTxn = algosdk.signMultisigTransaction(...).blob;

// check account information
let account = algodClient.accountInformation(...).do()

Rekey Transaction

1. For a rekey transaction, create a payment transaction with the following,
   • Set the amount 0.
   • Receiver has the same address as the sender.
   • Specify the account to rekey to.
