These contracts automatically execute when predetermined conditions are met, eliminating the need for intermediaries. For example, a smart contract can ensure that only verified users can trade a tokenized fund. They’re like vending machines for digital assets – you put in the right conditions (like payment), and you get the expected result (like a token).
Top TRC20 Tokens
The ERC-20 standard has seeped into almost every corner of the crypto ecosystem. A large number of popular tokens, such as the stablecoin tether and leading oracle service Chainlink, are actually ERC-20 tokens under the hood. The increasing demand for Ethereum transactions has led to network congestion and high gas fees, hindering the scalability and potential usage of ERC20 tokens.
Crypto Unlocks to Watch in the Next Days
If you’re creating a currency or a token that needs to be easily divisible and interchangeable, ERC-20 is probably your best bet. If you’re creating unique digital assets, like art or collectibles, ERC-721 is the way to go. And if you need a mix of both, or you want to save on gas fees by bundling different types of tokens into a single contract, ERC-1155 might be the answer.
Security Considerations for Smart Contracts
For example, some standards focus on improving security tokens and compliance, while others aim to streamline complex financial instruments. There are several types of blockchain token standards, each designed for different purposes. The most common ones you’ll hear about are ERC-20, ERC-721, and ERC-1155, all on the Ethereum blockchain. ERC-20 is for fungible tokens (like regular cryptocurrencies), ERC-721 is for non-fungible tokens (NFTs), and ERC-1155 is a hybrid that can handle both. It’s like having different types of vehicles – cars, trucks, and motorcycles – each suited for different tasks.

Ethereum, or ether, is a cryptocurrency that allows for the creation of a variety of applications, including tokens, that don’t require intermediary services to operate, unlike most traditional applications. Ether (ETH) is the native token used by the Ethereum blockchain and network as an internal payment system. ERC-20 is the standard for creating smart contract-enabled fungible tokens to be used in the Ethereum ecosystem.
ERC-20, the most widely adopted token standard on the Ethereum blockchain, has profoundly influenced the development of other token standards and protocols within the cryptocurrency ecosystem. DEXs rely on the “balanceOf” function to verify token ownership and facilitate swaps and trades effectively. Moreover, smart contracts leverage the “balanceOf” function to enforce token-based functionalities like staking, voting, or reward distribution https://ai-robert.com/ based on users’ token balances.
