How to read smart contract data?

What is ERC-721?
  • Smart contracts are autonomous digital agreements that play a pivotal role in cryptocurrency transactions.

  • Gaining an understanding of how to interpret smart contract data is vital for maintaining security and avoiding potential scams.

  • Various tools are available that can assist users in reading and understanding smart contract data.

What is a Smart Contract?

A smart contract is a digital agreement that carries out transactions based on predefined conditions. These contracts are programmed to make decisions and execute transactions between multiple parties without the need for manual intervention or trust.

For example, if you aim to obtain a loan on a Decentralized Finance (DeFi) protocol, the smart contract of the protocol intends to issue you a loan as soon as it verifies that you have locked the required collateral. The smart contract aims to automatically release your collateral once you repay the loan.

Why is Understanding Smart Contracts Important?

Once you agree to a smart contract, it automatically executes and the agreement is final—it cannot be undone. That's why it's crucial to fully understand what you're agreeing to.

For example, scammers might mimic well-known games and offer victims NFTs that they can stake in exchange for rewards. But the smart contract might actually be set up to allow scammers to take all the funds from the victim's wallet as soon as they approve the transaction.

Being able to read and understand a smart contract is key to avoiding these types of scams.

How to Interpret Smart Contract Data?

There are tools available that can assist you in reading smart contract data.

To use these tools, you first need to locate the smart contract address for the project you're examining. This can typically be found on a project’s official website, white paper, or marketplace listing page.

Once you have the smart contract address, you can input it into the search bar of the tool to access the smart contract’s page. Here, you may find a variety of information such as the creator address, token name, tokens held in the contract, and so on.

Interpreting the Statistics of a Contract’s Tokens

Tools can provide statistics of a contract’s tokens and what they convey. This includes information about the total supply of tokens, the number of holders, and the number of transfers. This information may help you gauge the activity level of a project.

Accessing the Source Code of a Contract

For a more in-depth analysis, the source code of a contract may be accessible. This could help you understand the functions of the contract and how it operates.

However, reading the source code requires some understanding of programming languages such as Solidity.
