Mesh 1.5.0

• Add sendToken to the transaction builder
• Add support to more than 20 fungible tokens including DJED and SHEN
• Implement a brand new Coin Selection Algorithm called Keep Relevant
• Enable using Plutus Script Reference for minting

Mesh 1.4.0

Dandelion Support

Now you can provide a custom base URL when instantiating a cardano provider using MeshJS, thus you can use one of the already deployed services on Dandelion in your MeshJS App.

Ogmios Provider

MeshJS is officially adding Ogmios as one of the Cardano data providers, allowing users to use evaluateTx ,submitTx, and onNextTx natively. it uses the Ogmios instance deployed on Dandelion by default, but it also accepts custom URL if you have one deployed already.

Define IEvaluator and IListener contracts

Two new contracts got added to MeshJS allowing the evaluation of smart-contract transactions, to better estimate the budget required to execute a transaction thus reducing fees, and listening to newly submitted transactions and getting a callback executed as soon it gets confirmed on-chain.

Mesh 1.3.0

Minting Assets using Plutus Scripts

Mint tokens with a smart contract, utilizing the Plutus validator to determine under what kind of conditions to allow the minting to take place.

Prove Wallet Ownership with DataSign

Cryptographically prove the ownership of a wallet by signing a piece of data using DataSign. This Guide will show how to use the newly implemented checkSignature function to authenticate users.

Enable Staking Transactions

New APIs for staking ADA and managing stake address - register, unregister, stake, and withdraw operations.

Support Reference Scripts in Transactions

You can reduce the size and cost of your transactions by using reference scripts.

Mesh 1.2.1

• ADA Handle Support Added
• Tangocrypto Provider Added
• Add Support for preview and preprod to Koios Provider
• Add fetchAssetAddresses to fetcher contract

Mesh 1.2.0

Mesh React

Mesh provides a collection of useful UI components, so you can easily include web3 functionality and convenient utilities for your application. To start, install the new mesh-react package:

yarn add @martifylabs/mesh-react

MeshProvider

MeshProvider was added to allow your app to subscribe to context changes and wallet states.

import { MeshProvider } from "@martifylabs/mesh-react";

function MyApp({ Component, pageProps }: AppProps) {
  return (
    <MeshProvider>
      <Component {...pageProps} />
    </MeshProvider>
  );
};

UI Components

Mesh offers UI components you need to build your dApp, so you can jumpstart your next project and bring the user interface to life.

In this release, we introduce CardanoWallet and MeshBadge:

import { CardanoWallet } from '@martifylabs/mesh-react';

export default function Page() {
  return (
    <>
      <CardanoWallet />
      <MeshBadge dark={false} />
    </>
  );
}

Wallet Hooks

In a React application, Hooks allows you to extract and reuse stateful logic and variables without changing your component hierarchy. This makes it easy to reuse the same Hook among many components.

In this release, we introduce the following React hooks:

• useWalletList
• useAddress
• useAssets
• useLovelace
• useNetwork
• useWallet
