How to Decode Web3 Data into a Human-Readable Format

In the world of development, we often experience challenges with encoded errors, logs, or data in general. This data, typically presented in an encoded format, is in a lot of different use cases required to be human readable and thus we need libraries to decode it effectively. At we came across this need internally, and so we decided to open-source the decoder service we have built. web3 blocktorch There are many good reasons why data is encoded, for example, efficiency, integrity, and data security. But, of course, as long as humans are in the loop to work with the data, decoding the data and respective decoder services are indispensable. For example, we triggered a transaction and got this error: . From that encoded data alone it is hard to understand the actual error and consequently fix the issue. 0xf32bec2f The simplifies the decoding process of the data into a human-readable format, thereby enhancing efficiency and clarity in your web3 engineering tasks. blocktorch-xyz/decoder How the decoder service works To use the decoder, all you require is the (ABIs) of the relevant smart contract in addition to the encoded data. Application Binary Interfaces Using the previously mentioned example (error , we will proceed to decode the data. To accomplish this task, we construct a call to the containing ABIs associated with the smart contract, and the encoded data. The smart contract we use in our example is the Aggregation Router from on with address 0x1111111254eeb25477b68fb85ed929f73a960582. 0xf32bec2f) blocktorch-xyz/decoder 1inch Network Polygon The ABI for verified and published smart contracts can be found on block explorers — for example we are using polygonscan to derive the smart contract ABI:
