Cryptocurrencies include various coins and tokens, each serving different purposes. Coins like Bitcoin (BTC) and Ethereum (ETH) run on their own blockchains and are used for transactions and as stores of value. Tokens, created on existing blockchains like Ethereum, serve specific functions in decentralized applications, such as ERC-20 for utility and ERC-721 for unique digital assets. Nadcab Labs, a leading blockchain development company, specializes in creating both coins and tokens. They provide tailored solutions for developing secure and efficient blockchain networks and tokens, ensuring comprehensive support from conceptualization to execution, including security audits and smart contract development.
