## Examples

```python3

>>> from diem import jsonrpc, testnet
>>> client = jsonrpc.Client(testnet.JSON_RPC_URL)
>>> client.get_metadata()

You can find more examples under the [`examples`](./examples/) directory:

* [Create Child VASP account](./examples/create_child_vasp.py)
* [All Types Peer To Peer Transfer](./examples/p2p_transfer.py)
* [Intent Identifier](./examples/intent_identifier.py)

Note: `make test` runs all examples too, see the Makefile for details.

### Off-chain service example

Checkout [MiniWallet](./src/diem/testing/miniwallet/app) implementation for off-chain service implementation example.

## MiniWallet and MiniWallet Test Suite

See [mini_wallet.md](mini-wallet.md)


## Build & Test

```
make init
make test
```

run specific test:

```
make test t=<test file / test name match pattern>
```

run with local docker testnet (requires initializing diem submodule):

```
make test t=<test file / test name match pattern> dt=1
```

## Re-generate diem_types, stdlib, jsonrpc response data structures

```
git submodule update --init diem
cd diem
git pull origin main
cd ..
make gen
```
