Having contracts on the local blockchain is nice, but we want to deploy them to the real chain and make them accessible to the world. We will deploy our contracts to the Coston testnet, which is a public testnet for Songbird that is used by many projects. Since Flare/Songbird/Coston is…

The custom tokens are fine and well, but let’s see how to interact with the native chain tokens and move them around. We will create a simple vault contract. Users will be able to deposit native tokens to the contract and withdraw it back after some time (Exercise: come up…

We now have a token, but it is pretty basic. Let’s add some more functionality to it. Before we start writing the code, we should pause a bit and try to think about what we want to achieve. The token should be able to perform a few necessary functions Transfer…

Before starting, make sure that you have your .env file in order (it should contain the private key, otherwise the hardhat will compile). The contract Let’s start with a simple token. Create a new file in the contracts/ directory and name it MyToken.sol and write the following code in it: Run…
