BFS-Contract

(ICON JAVA SCORE)

Getting Started

Requirements

1. Openjdk 11

2. goloop CLI see. https://icondev.io/getting-started/how-to-write-a-smart-contract

$ git clone [email protected]:icon-project/goloop.git
$ GOLOOP_ROOT=/path/to/goloop
$ cd ${GOLOOP_ROOT}
$ make goloop
$ ./bin/goloop version

goloop version v1.2.6 ...  # Success if version information is displayed.

Generate a keystore and get test ICX

$ ${GOLOOP_ROOT}/bin/goloop ks gen --out keystore.json --password xxxx

hxd9d79a5695f...2459905 ==> keystore.json  # Success if hxADDR is displayed.

Faucets for test ICX: https://icondev.io/icon-stack/icon-networks/main-network#test-network-faucets

Build

./gradlew build
./gradlew optimizedJar

Test

./gradlew cleanTest test -i

Deploy

Generate a keystore and get some ICX for deploy(see above.)

Following environment variables must be set before deploy

Name	Description
GOLOOP_RPC_URI	URI for RPC Endpoint (ex: http://localhost:9080/api/v3)
GOLOOP_RPC_NID	Network ID of the endpoint
GOLOOP_RPC_KEY_STORE	Keystore file for the wallet to send transaction
GOLOOP_RPC_KEY_SECRET	Secret file containing the password for the keystore file
GOLOOP_RPC_KEY_PASS	Password for the keystore file

Deploy the optimized jar to the network

./gradlew deployToRpc

Sample output

Starting a Gradle Daemon (subsequent builds will be faster)

> Task :java-score:deployToRpc
>>> deploy to http://localhost:9080/api/v3/icon_dex
>>> optimizedJar = /Users/mksong/work/bfs/bfs-contract/java-score/build/libs/java-score-0.9.0-optimized.jar
>>> keystore = owner.json
Succeeded to deploy: 0xfca11dc8120e65b8fb65fe72f282d6de0155e59dab9fbcafa23a10cf3b530c3d
SCORE address: cx9bcca392c17b838b7f8caac07e75f255a8370914

BUILD SUCCESSFUL in 5s
3 actionable tasks: 1 executed, 2 up-to-date

Then you should set the environment variable, BFS_CONTRACT, as the address of the deployed contract. For further commands. For the previous sample output, it may use the following for it.

export BFS_CONTRACT=cx9bcca392c17b838b7f8caac07e75f255a8370914

Then you can check the list of nodes with the following command.

./gradlew allNode

Update

To update the contract with the new code, use the following command.

./gradlew deployToRpc -PdeployTarget=<contract address>
