"We could've fought it," Robinscan said in an X post on Tuesday, Sept. 15. "Instead, we took it as a sign to finish what we'd started."
The team said it rebuilt the interface within days and launched a redesigned version.
Etherscan's operator sent the letter on Sept. 9, five days before Etherscan announced Robinhood Chain support.
Etherscan, one of crypto's most widely used services for looking up blockchain transactions, addresses and smart contracts, added support for Robinhood Chain, an Ethereum-compatible Layer-2 network designed by Robinhood around tokenized stocks, crypto and memecoins, Etherscan announced in an X post on Monday, Sept. 14.
- Robinhood launched the network's public mainnet on July 1, but the 75-day gap didn't mean Robinhood Chain had been operating without a block explorer.
- Blockscout has served as the chain's official explorer "from block one" and Robinhood's own developer documentation still directs users there for transaction data.
Etherscan's arrival also appears to have made one community-built alternative redundant almost overnight.
RH-Scan, an independent Robinhood Chain explorer launched in July 2026 by an unnamed community team behind the @rh_scan account, announced that it would shut down following Etherscan's launch.
"There is no further reason for us to exist, as @etherscan finally released the explorer everyone deserves," the team said, adding that the site would remain online during the transition and joking that it might return "for the next L2 launch."
Blockscout's documentation explicitly noted until recently that Etherscan didn't support Robinhood Chain, despite the network being fully compatible with Ethereum tooling.
The delay stands out because other infrastructure arrived immediately.
- Chainlink went live on Robinhood Chain from day one as its official data and cross-chain oracle provider, while blockchain analytics firm Elliptic also supported the network at launch.
- Trading infrastructure provider 0x similarly announced day-one integration.
- Etherscan hasn't publicly explained why support arrived more than two months later.
The addition doesn't replace Blockscout, but it gives developers and users another familiar way to inspect activity on Robinhood's increasingly busy blockchain.
