* Cryptocurrencies
: like Bitcoin (BTC) or Ethereum (ETH), which can be traded on online exchanges.
* Smart Contracts : Self-Executing Contracts with the terms of the agreement written directly into lines of code. Examples include voting systems and insurance policies.

ERC-20 Tokens have been widely adopted in Various Industries, including:
- Finance: cryptocurrencies, derivatives, and stablecoins are all built on top of ERC-20 Token standards.
- Gaming: many gaming platforms, such as opensea and rarible, use ERC-721 for their NFT collection.
