Hi, all very happy to share this new approach to create ERC20 Token using Hyperledger Fabric for private blockchain.

Now, lets get started.

we will first look into the arc of Hyplerledger Fabric (HLF). then will see development setup along with creating chaincode for our Dapp.

check out detailed Medium article of this project [https://medium.com/@akshay.kurhekar1014662/erc20-token-implementation-in-hyperledger-fabric-103cbfc21379]

1. up network

check fabric binary:
run from any folder

$ docker images

if you find fabric images

cd token-erc-20

$ ./networkUp.sh

to deploy chaincode we need to run this script
 cd token-erc-20

$ ./deployChaincode.sh Chaincode_Name

-------------------------------

Now, lets move towards application part

$ cd api_server $ npm i

$ node registerAdmin.js

output:
Wallet path: /home/akshay/fabric/HLF-erc20Token-starter/token-erc-20/api-server/wallet
Successfully enrolled admin user "admin" and imported it into the wallet

$ node registerMinter.js

we invoke chaincode by this user Rama we have setToken details and fech data from ledger.

$ node invokeByMinter.js out put: Token details :: DevToken

day - 2 

create chain code fun for mint, transfer along with balance and accountId

Note:
once you deploy chaincode, if you updated logic of chaincode and you want to use that logic
need to upgrade chaincode with new_cc_name.

$ cd token-erc-20

$ ./upgradeChaincode.sh CC_Name

After upgrading chaincode we will test our ERC20 token functions

In node app by invokeByMinter script for minting 9000 Tokens Transfer it to different user and check balance .

$node invokeByMinter.js To stop container $ docker stop

To down network or we can say that to close development setup we need to do.

$ cd token-erc-20

check files you will get networkDown.sh script we need to execute it.

$ ./networkDown.sh
