In the world of web3 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 blocktorch we came across this need internally, and so we decided to open source the decoder service we have built.
There are a number of good reasons of 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: 0xf32bec2f . From that encoded data alone it is hard to understand the actual error and consequently fix the issue.
The blocktorch-xyz/decoder simplifies the decoding process of the data into a human-readable format, thereby enhancing efficiency and clarity in your web3 engineering tasks.
How the decoder service works
To use the decoder, all you require is the Application Binary Interfaces (ABIs) of the relevant smart contract in addition to the encoded data.
Using the previously mentioned example (error 0xf32bec2f), we will proceed to decode the data. To accomplish this task, we construct a call to the blocktorch-xyz/decoder containing ABIs associated with the smart contract, and the encoded data. The smart contract we are using in our example is the Aggregation Router from 1inch Network on Polygon with address 0x1111111254eeb25477b68fb85ed929f73a960582.
The ABI for verified and published smart contracts can be found on block explorers - for the example we are using polygonscan derive the smart contract ABI: https://polygonscan.com/address/0x1111111254eeb25477b68fb85ed929f73a960582#code

Once you know the data you want to decode, the smart contract address and ABI you can trigger the call to the decoder service.
For our example we trigger the following call:
POST /api/internal/transaction/decode
{

The same will also work in case the smart contract uses a proxy, all you need to do is provide the proxy ABI and the service will decode it for you.
Running the web3 data decoder locally
1.Clone the repository
git clone git@github.com:blocktorch-xyz/decoder.git
- Add .env.development file with the following envs (remark: as a general best practice if you push to github please always ensure the files your environment variables are stored in are included in your .gitignore file)
BASIC_AUTH_INTERNAL_USERNAME=username
BASIC_AUTH_INTERNAL_PASSWORD=very-secure-password
- Install dependencies and run the service
npm i
npm run dev
or
yarn
yarn run dev
That's it, you can run the following call to test it
curl --location 'http://localhost:8000/api/internal/transaction/decode' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic dXNlcm5hbWU6dmVyeS1zZWN1cmUtcGFzc3dvcmQ=' \
