Crypto Trends 29 March 2021

Crypto Trends

A summary of the crypto trends for the week.

Uniswap v3

Better deals for users (less slippage and a future Optimism deployment).

Uniswap v3 uses Business Source License 1.1, essentially a time delayed GPL 2. It will be interesting to see if other projects adopt this approach for some protection from forks.

Community launch of Optimism ~ July

Updated timeline based on community feedback, integrating more infrastructional/foundational projects before the community launch (e.g. a multisig).

Testnet for Scaling Ethereum hackathon for 20th April.

Remix @ imports + deep linking

We can now use @ imports in Remix (Live). Try out the following contract in Remix:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyToken is ERC20 {
    constructor() ERC20("MyToken", "MTK") {
        _mint(msg.sender, 1000000 * 10 ** decimals());

@ imports and deep linking allow some very cool functionality. :mage:



OpenZeppelin are hiring:


VB on Legitimacy

I have been publishing #crypto-trends for over a year now. :birthday:


Wasn’t buidler-evm released under a similar license back in the day?
