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
- We have already deloyed an
ERC20contract for you that gives you rights to mint new coins and send to user's wallets. - Fetch the token id: Get the
testERC20tokenDataIdsof 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 -62a369c43a45893dcf7bae66is thetokenDataId. - Send the tokens: Use the following API to mint new
ERC20tokens to a wallet. eg. here we will mint 100000 of this into my walletId -627cb7ea2cd263018f2adfb7. See API Reference for code snippets in more languages ↗️
