A secure messaging workflow specification

This document describes how to implement a DSL workflow using smart contracts for a secure messaging smart control protocol.

It contains building blocks that can be apply to other domains (DeFi, supply chain, flash loans, and others)

Define states

After your discovery phase and business requirements, create the different states that will define the workflow.

export class WalletConnectDappUtils {
  public static async waitFor(methodResponse: any) {
    let result: any = {};
    // CANNOT BE executed with the plugin due to next tick issues with Javascript
    let exit = 5;
    let n = methodResponse.beforeBlock - 2;

solido-provider-wallet

Solido Wallet Provider

Implementing WalletConnect Protocol for a VeChain Dapp

solido-provider-wallet is a wrapper for solido-provider-connex which injects a SolidoSigner interface that sends signing requests to WalletConnect.

Additionally, a Dapp needs to instantiate a self hosted connex. To create a new connex instance, add @vechain/connex-framework and @vechain/connex.driver-nodejs. The latter only works with server side applications but is enough to let us create a connex object.
