truffle-config.js

/**
 * 
 * Use this file to configure your truffle project. It's seeded with some
 * common settings for different networks and features like migrations,
 * compilation and testing. Uncomment the ones you need or modify
 * them to suit your project as necessary.
 *
 * More information about configuration can be found at:
 *
 * trufflesuite.com/docs/advanced/configuration
 *
 * To deploy via Infura you'll need a wallet provider (like @truffle/hdwallet-provider)
 * to sign your transactions before they're sent to a remote public node. Infura accounts
 * are available for free at: infura.io/register.
 *
 * You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
 * public/private key pairs. If you're publishing your code to GitHub make sure you load this
 * phrase from a file you've .gitignored so it doesn't accidentally become public.

            Transactions on Polygon network are dirt cheap. Forget Ethereum, forget BSC, we're talking 
            about fractions of a cent for most transactions. So this faucet will only send you 0.0005 
            MATIC - which is enough to deposit some fund on Aave and earn fresh MATIC, for instance
            With 0.001 MATIC, you can do 100 basic transactions on Polygon network ! You can even deposit 
            or withdraw funds on Aave, even though it is a pretty expensive transaction (50$+ on Ethereum, 
            1$+ on Binance Smart Chain). The goal of this faucet is not to make you rich but just to make 
            the onboarding to Polygon smoother. You can use it up to 3 times a day, for the most clumsy 
            of us 🙄 Feel free to send some spare change at 0x8C5a6C767Ee7084a8C656Acd457Da9561163aE7E 
            to replenish the faucet once you're rich 🦄

            How to earn (much) more MATIC ?

            First bring your assets from Ethereum to Polygon through the bridge
            Then there's a variety of things you can do:
                Swapping assets on QuickSwap or ComethSwap, the equivalents of Uniswap on Polygon
                Paraswap is also available and will route your swaps through the cheapest path.
                Depositing your assets on Aave or Curve to farm some fresh MATIC
                Enjoy the same functionalities Ethereum has, only with less friction 🦄
