Chains
SharpBlock covers Robinhood Chain and Base. How to switch, what carries over, and what doesn't.
SharpBlock covers two chains today. You pick one at a time from the selector in the header, and everything on screen — prices, tokens, blocks, search results — belongs to that chain.
The chains
Robinhood Chain
The default. An EVM chain with chain ID 4663, native token ETH.
Most tokens on Robinhood Chain launch on flap.sh, a launchpad. That has a practical consequence for what you'll see: a token still on its bonding curve has no DEX pair yet, so the usual market-data providers return nothing for it. SharpBlock falls back to flap's own data for name, symbol, price and logo until the token graduates and gets listed on a DEX.
If a very new Robinhood token shows sparse or zero trading stats, it usually hasn't graduated off the launchpad yet — not a bug.
Base
Coinbase's L2. EVM, chain ID 8453, native token ETH. A mature ecosystem, so tokens here generally have full DEX coverage, holder data and price history.
Switching chains
Use the selector in the header. Your choice is:
- Remembered between visits, and
- Reflected in the URL as
?chain=baseor?chain=robinhood, so a link you copy opens on the chain you were viewing.
Why switching sometimes sends you home
Tokens, wallets, transactions and blocks exist on exactly one chain. There is no meaningful equivalent of "this transaction, but on Base" — that hash simply isn't there.
So if you switch chains while viewing one of these pages:
/token/…/wallet/…/address/…/tx/…/block/…
SharpBlock takes you to the homepage on the new chain rather than showing you a broken page.
List pages behave differently — the homepage, Gems, Blockchain, Favorites and Verified all stay where they are and simply reload with the new chain's data.
What about Ethereum and Solana?
Both are recognised internally — SharpAI can answer questions that name them explicitly — but neither is offered in the chain selector. Ethereum and Solana don't have the full explorer surface behind them, and Solana isn't EVM at all, so the address, transaction and block pages can't render it.
If you're looking for full Ethereum mainnet coverage, SharpBlock isn't that today.
