Create & send FT

Send ERC20 coins to a user and check balance

🔭 Guide overview

In this guide you will send ERC20 tokens. After sending, will check user wallet balance.

📘

ERC20: Crypto Coins 🪙 , also known as fungible tokens.

The ERC-20 introduces a standard for Fungible Tokens, in other words, they have a property that makes each token be exactly the same (in type and value) as another token. For example, 1 ERC-20 token is and will always be equal to all the other tokens. Some popular examples of ERC-20 tokens are WETH, MATIC.

Learn more about the type of tokens: Ethereum.org docs on ERC20 tokens ↗️

🏷️ Use-case examples with the Croak ERC-20 APIs

• Reward users with coins
• Airdrop tokens to non-users for inviting them to use your application
• Reward community members for their contributions
• Send a user coins/fungible tokens in exchange of fiat payments. These coins can be used for ingame actions
• Assign reputation points for users in an online platform
• Assign financial assets to shareholders like a share in a company/dao

🧱 Implementation steps

1. We have already deloyed anERC20 contract for you that gives you rights to mint new coins and send to user's wallets.
2. Fetch the token id: Get the testERC20tokenDataIds of your client. If you don't already have it saved go to Get Company API Reference ↗️ and create a new client to start using. Here we will assume - 62a369c43a45893dcf7bae66 is the tokenDataId.
3. Send the tokens: Use the following API to mint new ERC20 tokens to a wallet. eg. here we will mint 100000 of this into my walletId - 627cb7ea2cd263018f2adfb7. See API Reference for code snippets in more languages ↗️
