Algorand sandbox#

Initialization#

@2021-12-15
Examples

## Available accounts
./sandbox goal account list
## Example command to send between two accounts:
./sandbox goal clerk send -a 123456789 \
  -f 5FCT5DRXI0777MGBPGZUC7YWSQVIQQCWPQGOYZKYETPXA0K3PV3ZPOK5IM \
  -t GUJLQG20ALKCGD3DFLC3A5BCOYEK6HAI3UJBSJ6TRJ3YEGY4FQLBUBOZGY
# -a amount, -f from, -t to
## Soon after sending the transaction it will appear in indexer:
# check
curl "localhost:8980/v2/transactions?pretty"

Setup system env var
- export SANDBOX_DIR="PATH/TO/algorand/sandbox" #to the sandbox dir
- Or put project directory next to sandbox(share same parent dir)
- Important for VSCode: python interpreter should set to the python executable file of the venv.

What is sandbox#

@2021-12-24
(wrong:) I thought sandbox is a virtual chain, and we could create account, run transaction and smart contract inside the sandbox. But it's actually not.
(summary:) Algorand is a chain, on this chain we have several "client" to run different "smart contract". Sandbox is a quick way to setup a "client" so that we can deploy our smart contract on algorand (testnet).
From the repo, it's said "a fast way to create and configure an Algorand development environment with Algod and Indexer."
Algod is an Algorand's official implementation in Go. To me It's an client, who controls, maintains and executes the smart contract(s). I think the name stands for algo-docker, containing all features of algorand PoS chain. (update 220324: algo-daemon)
Indexer. To my understanding it's a server of the algod client, who keeps track of all the transactions and smart contracts executed by its algod client.
All py-algorand-sdk functions will run on testnet.

Interact with sandbox#

Create an account in sandbox: the sandbox is like a local smart contract client, you can't create account in sandbox.

Pending for sandbox#

[ ] what does those accounts on 8980 port do?
[ ] Are the on testnet / main net?

Better sandbox#

@2021-12-25
Instead of sandbox, we should usehttps://developer.purestake.io/
Reason: sandbox has some problem. The sample code is not working with error ``
