"We're seeing builders move fast to Robinhood Chain," a Chainstack spokesperson told us. The infrastructure platform just went live with support for the new Arbitrum Orbit layer 2, offering endpoints across Global Nodes, Dedicated Nodes, and Chainstack Self-Hosted deployments. Robinhood Chain itself launched mainnet in early July, and Chainstack's infrastructure is now ready for both mainnet (chain ID 4663) and testnet (chain ID 46630).
What makes Robinhood Chain different from the growing pile of EVM-compatible chains is its design focus. It's built as an Arbitrum Orbit chain running the Nitro stack, purpose-built for finance and tokenized real-world assets. Blocks land every 100 milliseconds with sub-second soft confirmations, uses ETH as gas, and settles data to Ethereum via blobs for full finality in roughly 13 minutes. The chain exposes standard Ethereum JSON-RPC, so Foundry, Hardhat, ethers.js, viem, and web3.py work without modification. Solidity contracts deploy unchanged. That compatibility matters because it cuts onboarding friction for teams moving from Ethereum.
There's one quirk traders need to know: Robinhood Chain's sequencer orders transactions strictly first-come, first-served by arrival time, not by fee. That means a higher priority fee won't bump your transaction ahead in the queue. Endpoint latency, not gas strategy, determines execution outcomes. For high-frequency trading workloads, node placement becomes an execution concern, not a cost optimization problem. Chainstack's three deployment paths handle different needs. Global Nodes offer elastic, load-balanced infrastructure metered in request units. Dedicated Nodes give you an isolated instance with unlimited requests and full configuration control. Chainstack Self-Hosted puts the stack on your own cloud, on-premises, or bare metal with complete control and no metering. The platform already serves 100,000 developers across 70+ blockchain networks, so the addition signals mainstream adoption momentum for Robinhood Chain as financial applications start moving infrastructure.
