Blockhead: SH '24

Blockhead is an open-source interface for the decentralized web, with a portfolio tracker, multi-chain block explorer, and browsers for various web3 protocols.

For Superhack 2024, I created an explorer for Ethereum Attestation Service. Browse recent attestations, schemas, attesters, attestees and smart contract deployments across all supported networks (including Ethereum, OP Mainnet, Base, and many more). IPFS content, transactions, and accounts are embedded throughout the views and link to corresponding pre-existing protocol explorer views throughout Blockhead's interface.

Additionally, the Explorer has been updated to support most Superchain networks (OP Mainnet, Base, Celo, Fraxtal, Mantle, Metal L2, Mint, Mode, Redstone, Zora Network) and their testnets, along with an experimental live timeline view to visualize recently published blocks.

Tech stack:

SvelteKit + custom UI components

Blockscout's REST API + RPC network for onchain data, verified smart contracts

Easscan GraphQL API for Ethereum Attestation Service data

Infura's EAS IPFS endpoint for attestation data posted to IPFS

Tanstack Query + visjs-timeline for live timeline view

Conduit data manually pulled from dashboard for rollup stack metadata
