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 tested the fast-bridge I use the USDC tokens on testnet. The fast-bridge is dependent on the classical rainbow bridge, which has a lot of components and is already deployed on the testnet. In this case it was much easier to use tokens, which are already supported by the classical rainbow bridge.

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.
