You can find more examples under the examples directory:

• Create Child VASP account
• All Types Peer To Peer Transfer
• Intent Identifier

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

Wallet Example: this is a highly simplified example of a wallet backend server implementation (no UI, no database, no un-related APIs) for demonstrating building off-chain API services through the Python SDK off-chain module.

To start the example as a local http server:

make init
source venv/bin/activate
make server

Example curl to hit the server (should get an error response):

curl -X POST -H "X-REQUEST-ID: 3185027f-0574-6f55-2668-3a38fdb5de98" -H "X-REQUEST-SENDER-ADDRESS: tdm1pacrzjajt6vuamzkswyd50e28pg77m6wylnc3spg3xj7r6" -d "invalid-jws-body" http://localhost:8080/v2/command

See mini_wallet.md

make init
make test

run specific test:

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

run with local docker testnet:

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

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