Welcome to SharpBlock
A block explorer for Base and Robinhood Chain with an AI assistant that answers questions about tokens, wallets and transactions in plain English.
SharpBlock is a block explorer built for people who are trying to make sense of a token, not just read raw chain data. Alongside the usual explorer surfaces — blocks, transactions, addresses — it ships SharpAI, an assistant you can ask questions like "who are the biggest holders of HOODER?" or "is this contract a honeypot?" and get a real answer instead of a wall of hex.

Plain-English questions about tokens, wallets, blocks and transactions.
Find new tokens
Filter the market by market cap, volume, category and verification.
Supported chains
SharpBlock currently covers two chains, switchable from the chain selector in the header:
| Chain | Chain ID | Native token | Notes |
|---|---|---|---|
| Robinhood Chain | 4663 | ETH | The default chain. Most tokens here launch on flap.sh. |
| Base | 8453 | ETH | Coinbase's L2. |
Your choice is remembered between visits, and it's part of the URL
(?chain=base) so links you share open on the right chain.
Chain-specific pages
A token, wallet, transaction or block belongs to exactly one chain. If you switch chains while viewing one of those pages, SharpBlock sends you back to the homepage — that record doesn't exist on the other chain.
