Requirements & limits
- The project extends bs58 with Base58Check checksum handling.
- The README demonstrates importing the package and calling decode and encode.
- The public repository identifies the license as MIT.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Source-based practical guide
Decode and re-encode a Base58Check string
Convert the example Base58Check string to bytes and encode those bytes back to a string.
Before you start
- A JavaScript project that can import
bs58check.
Steps
Import
bs58checkfrom the package.Call
bs58check.decode()with the example string shown in the README.Pass the decoded bytes to
bs58check.encode().
Expected outcome
The example bytes are produced and re-encoding them yields the original string.
Guide limitations
- The README demonstrates only the stated example; it does not document installation steps or error handling.
