Launching your base token using thirdweb

If a developer wants to have their own base token for a [virtual chain] launched via AuroraCloud, they can use, for example, OpenZeppelin or Aurora Contracts.

But what if you're just a beginner in the web3 world? thirdweb comes to the rescue here and provides an easy UI to do exactly that - deploy, mint, burn your own ERC-20, and even allows conducting airdrops with it.

Of course, to be used as a base token for your [virtual chain] that token will need to be bridged to NEAR first via [OmniBridge], but we will discuss that in the next article.

Token burning is the act of permanently removing a certain number of tokens from circulation. This article delves into its intricacies and offers guidance based on my real-world experiences at Aurora

How to get USDC tokens on Aurora testnet

When you develop a contract, quite often you need ERC-20 tokens for testing. If your contract is rather small and doesn't use cross-contract calls, most likely, you don't need official USDC tokens or any other specific tokens. In that case, the best solution is just to take the standard ERC-20 contract, deploy it, and mint as many test tokens as you wish.

However, sometimes the easier solution for testing can be to get official testing tokens. For example, if your contract is use difficult cross-contract calls and dependencies contracts are already deployed on testnet and support only limited numbers of tokens. When I am testing RainbowBridge during development I use the USDC tokens on testnet.

In this article, I will explain how to get official native Ethereum ERC-20 tokens on your Aurora testnet account in the example of USDC tokens. This method will work with other popular native Ethereum ERC-20 as well, and it will be clear how to get these tokens also in Goerli Ethereum and in Near testnet.
