OpenST Payments - Advance Payment infrastructure on top of the OpenST network

Latest version Travis Downloads per month Gitter: JOIN CHAT

While OpenST 0.9 is available as-is for anyone to use, we caution that this is early stage software and under heavy ongoing development and improvement. Please report bugs and suggested improvements.

Install OpenST Payments

npm install @openstfoundation/openst-payments --save

Init DynamoDB

Following commands need to be run once, only for the first time. DynamoDB initial migrations for shard management are run in it and one shard is created and registered for storing token balance.

. ./mocha_test/scripts/set_env_vars.sh
node tools/dynamo_db_init.js

Run Test Chain

cd mocha_test/scripts/
sh start_test_chain.sh

Set EVN Variables

Setup Initial Setup Variables:

export OST_UTILITY_GETH_RPC_PROVIDER=''
export OST_UTILITY_GETH_WS_PROVIDER=''
export OST_UTILITY_DEPLOYER_ADDR=''
export OST_UTILITY_DEPLOYER_PASSPHRASE=''
export OST_UTILITY_OPS_ADDR=''
export OST_UTILITY_OPS_PASSPHRASE=''

Deploy Branded Token Contract:

node tools/deploy/EIP20TokenMock.js conversionRate symbol name decimals gasPrice

Deploy Workers Contract:

node tools/deploy/workers.js gasPrice chainId

Deploy Airdrop Contract:

node tools/deploy/airdrop.js brandedTokenContractAddress baseCurrency workerContractAddress airdropBudgetHolder gasPrice chainId

Set Caching Engine:

export OST_CACHING_ENGINE='none'
For using redis/memcache as cache engine refer - [OpenSTFoundation/ost-price-oracle](https://github.com/OpenSTFoundation/ost-price-oracle)

Set DB Details For Payments/Airdrop:

export OP_MYSQL_HOST=''
export OP_MYSQL_USER=''
export OP_MYSQL_PASSWORD=''
export OP_MYSQL_DATABASE=''
export OP_MYSQL_CONNECTION_POOL_SIZE='5'

Create Airdrop Tables:

node migrations/create_tables.js
