How to use the package to update information on DeFiMetaChain

import {handler} from "@waveshq/state-relayer-bot";
import { EnvironmentNetwork } from "@waveshq/walletkit-core"

handler({
    testGasCost: false,
    urlNetwork: "https://ocean.defichain.com/",
    envNetwork: EnvironmentNetwork.MainNet,
    contractAddress: /* YOUR STATE RELAYER PROXY ADDRESS */,
    signer: /* signer object */,
    gasUpdateDEX: /* gas limit for dex update transaction */,
    gasUpdateMaster: /* gas limit for master node update transaction */,
    gasUpdateVault: /* gas limit for vault update transaction */
})

Instruction to consume the smart contract information

Examples on how to consume the information exposed by the smart contract is showcased via this folder and this folder

How to deploy your smart contract on DMCTestnet

Install the dependencies and compile smart contracts:

npm ci
npx hardhat compile

If you use .env file, just execute this:

npx hardhat run --network DMCTestnet scripts/deployment.ts

If you want to use Ledger, comment the accounts line and uncomment the ledgerAccounts line under DMCTestnet section. Execute this command:

npx hardhat run --network DMCTestnet scripts/deployment.ts

How to manage permission for smart contracts via Metamask

There are three main functions related to this: grantRole(bytes32,address), revokeRole(bytes32,address) and renounceRole(bytes32,address)

Clone the repo.

git checkout v0.0.1, (the version that the smart contract is deployed from)

Install dependencies and compile smart contract:

npm ci
npx hardhat compile

Copy file scripts/utils/generateEncodedData.ts from main onto this branch (v0.0.1) and then generate encoded data by executing this command line:

npx ts-node scripts/utils/generateEncodedData

After this, enable metamask to be able to show hex data.

Then when creating a transaction to send, enter the smart contract address as the recipient, then paste the generated encoded data into the "Hex data" field.

A similar flow is showcased in video/MetamaskInstruction.mov
