Walkthrough

The changes add support for ERC20 token prizes in hackathons by introducing logic to detect ERC20 prizes, fetch token symbols, and display the correct token symbol alongside prize amounts. The hackathon data structure and UI are updated to handle both ETH and ERC20 token prizes, with a helper function for formatting prize displays.

Poem

A token prize, not just in ETH,
Now hackathons can broaden their wreath!
With symbols fetched and prizes shown,
The blockchain’s bounty newly grown.
🐰 Cheers to tokens, big and small—
Explorer now can show them all!
