Quickstart

Java 8 (or higher) is required.
Docker is required for running smart contract tests.

1. Clone this git repo:

git clone https://github.com/bane-labs/bridge-neo-contracts.git

2. Go to the project directory:

cd bridge-neo-contracts

3. Compile the smart contract for the bridge:

./gradlew neow3jCompile -PclassName=network.bane.bridge.BridgeContract

4. You will see the following output in the directory ./build/neow3j:

$ ls -la build/neow3j
total 24
drwxr-xr-x  5 user  wheel  160 23 Feb 17:40 .
drwxr-xr-x  7 user  wheel  224 23 Feb 17:40 ..
-rw-r--r--  1 user  wheel  425 23 Feb 17:40 NeoXBridge.manifest.json
-rw-r--r--  1 user  wheel   94 23 Feb 17:40 NeoXBridge.nef
-rw-r--r--  1 user  wheel  430 23 Feb 17:40 NeoXBridge.nefdbgnfo

5. Compile the bridge management contract

./gradlew neow3jCompile -PclassName=network.bane.management.BridgeManagementContract

Then, similar to the bridge contract before, you will see the following output in the directory ./build/neow3j:

$ ls -la build/neow3j
total 24
drwxr-xr-x  5 user  wheel  160 23 Feb 17:40 .
drwxr-xr-x  7 user  wheel  224 23 Feb 17:40 ..
-rw-r--r--  1 user  wheel  425 23 Feb 17:40 NeoXBridgeManagement.manifest.json
-rw-r--r--  1 user  wheel   94 23 Feb 17:40 NeoXBridgeManagement.nef
-rw-r--r--  1 user  wheel  430 23 Feb 17:40 NeoXBridgeManagement.nefdbgnfo

6. Run the contract test

./gradlew test

7. Deploy the bridge contracts locally

• Run a local Neo Express instance. The project includes a Neo Express configuration file.
• Fund Alice's account: neoxp transfer 100 GAS genesis alice
• Go to the network.bane.scripts.deploy.DeployAll class and run it.
