Blockhead is an all-in-one browser for Ethereum, EVM-based blockchains, web3 protocols, and their collective ecosystem of DeFi apps, digital organizations and internet experiences.

It features a crypto/DeFi/NFT portfolio tracker; a cross-EVM block explorer; dynamic interfaces and explorers for smart contracts, DeFi protocols and web3 apps; and comprehensive data controls that let YOU decide the infrastructure powering the interface.

Blockhead pushes the limits of web3-native UX by embracing the multi-faceted architectural trade-offs at each layer of the web3 stack, synthesizing them into a unified interface that is informative, concise, transparent and adaptive toward many use cases.

With a local-first, dynamic, data-agnostic design, Blockhead is the ideal place to track, visualize and explore the decentralized world wide web!

🅱 Features/Integrations

🧮 Portfolio:

• Portfolio: create groups of Ethereum/EVM-based blockchain accounts to see associated token balances, DeFi balances and NFTs across the selected Ethereum and EVM-compatible chains and estimate their crypto net worth.
  • Add Account: enter a raw wallet address (0xabcd...6789), ENS name (e.g. vitalik.eth) or Lens handle (e.g. stani.lens), along with one or more supported EVM-based networks.
• Account:
  • Balances: sort assets alphabetically or numerically, and optionally hide small/irrelevant balances.
  • DeFi: view DeFi balances grouped by DeFi protocol (red-colored numbers denote debt/borrowed assets). Optionally show underlying assets backing vaults, liquidity pools, or index tokens.
  • NFTs: browse non-fungible tokens and their associated images, grouped by collection (contract). Optionally show their on-chain or off-chain metadata/attributes.
  • Feed: optionally show a live activity feed for supported web3 apps.
• Explore: Click any address, DeFi app, NFT contract name, ENS name or Lens handle to show more details in Explorer or Apps.
• Data transparency:
  • All data is sourced though data providers defined in Preferences and tagged with corresponding labels and icons throughout the interface.
  • Preferences and portfolio data are saved/cached within your browser's local storage.

🧭 Explorer:

• Explore blocks and transactions across several EVM-based blockchain networks: Ethereum, Polygon, Gnosis Chain, Arbitrum, Optimism, Aurora, Avalanche, BNB Smart Chain, Celo, Cronos, Evmos, Fantom and more!
• Network overview: monitor statistics for a given network including the current block height and the native currency's current/historical price.
• Look up a transaction ID, block number, or address (0xabcd...6789, ENS name or Lens handle) by typing in the search field or via URL (blockhead.info/explorer/{networkName}/{query}).
  • The search field query is preserved when switching chains so you can easily look up details for the same address across multiple chains.
• Address (externally-owned accounts or smart contracts):
  • Balances: native/ERC-20 token balances associated with the address. Click a token to filter for transactions involving that token.
  • Smart contracts: browse verified smart contract code from Sourcify (IPFS).
• Block (by block number):
  • Look up consensus metadata and associated transactions.
  • Cross-reference blocks produced around the same time on other chains.
• Transactions (by transaction hash):
  • Browse transactions in three levels of detail:
    • Summary: just the primary action and/or native currency transfers, based on context.
    • Detailed: includes just the smart contract event logs directly involving the address, based on context.
    • Exhaustive: includes all transaction fees and smart contract event logs.
• Data transparency:
  • All data is sourced though data providers defined in Preferences and tagged with corresponding labels and icons throughout the interface.

📱 Apps:

• Dynamic interfaces and data explorers for popular dapps and web3 infrastructure projects:
  • ENS: browse registration details and records associated with names on the Ethereum Name Service (e.g. vitalik.eth)
  • Lens: look up Lens profiles by Lens handle (e.g. stani.lens)
  • Audius: search the Audius network for music artists, curators, playlists, and tracks, and play tracks directly from IPFS
  • The Graph: browse GraphQL schemas for subgraphs of popular dapps
• Integrated dashboards, and visualizations for DeFi protocols/primitives:
  • Uniswap, Aave, Balancer, Compound, Curve, 1inch, Sushi, InstaDapp, Loopring, Superfluid, Liquity, Quickswap and more!

📒 Accounts & Wallets:

• Wallets: connect and manage multiple wallet connections simultaneously, with easy drag-and-drop access from a toggleable side panel
  • Supported wallet connection protocols: injected EIP-1193 (browser extensions, mobile in-app browsers), WalletConnect 1.0, WalletConnect 2.0, Coinbase Wallet SDK, webmax.js
  • Supported wallet brands: MetaMask, Rainbow, Coinbase Wallet, IntmaxWallet, Liquality Wallet
• Lens: "Sign in with Lens" to generate an access token and enable interactions within Lens protocol.

⚙️ Preferences:

• Appearance:
  • Theme: choose a light or dark theme for the interface.
• Blockchain Data:
  • On-Chain Data: relay read-only smart contract data through "official" JSON-RPC endpoints, Alchemy, Figment, Infura, Pocket Network, QuickNode or Tenderly.
  • Transaction/Blocks: fetch block/transaction metadata from Airstack, Covalent, Etherspot or the chosen JSON-RPC node.
• Account Data:
  • Token Balances: relay native tokens and ERC-20 balances through the specified indexer API or RPC network.
  • DeFi Balances: fetch DeFi balances from the Zapper API (off-chain) or the Zerion DeFi SDK (on-chain).
  • NFTs: fetch NFT metadata from Airstack, Covalent or NFTPort.
• Analytics:
  • Currency: denominate token balances in Ethereum, Bitcoin or your local fiat currency.
