Robinhood Chain

Daemon builds on Robinhood Chain, the Arbitrum-stack Ethereum L2 that went live on July 1, 2026. Scaffold a Foundry project, compile with a pinned compiler, and deploy to testnet from the same workspace you use for Solana.

What Robinhood Chain is#

Robinhood Chain is an Ethereum layer 2 built on the Arbitrum stack. Gas is ETH and contract deployment is permissionless, so standard EVM tooling like Foundry works against it. Solana stays Daemon's home; this is the same workbench pointed at a second chain. Daemon deploys to the testnet only; the mainnet is listed here for reference.

Network	Chain ID	RPC	Daemon deploy
Testnet	46630	https://rpc.testnet.chain.robinhood.com	Yes
Mainnet	4663	https://rpc.mainnet.chain.robinhood.com	Disabled

The official reference is at docs.robinhood.com/chain. The testnet faucet is at faucet.testnet.chain.robinhood.com, and blocks are viewable on the Blockscout explorer.

What Daemon adds#

Chain presets

Testnet and mainnet configs, RPC readiness checks, explorer and faucet links, ready in a project.

Foundry scaffold

A pinned-compiler starter with a Counter contract and a Chainlink stock-feed reader that checks for staleness.

Deploy and verify

Deploy to testnet with a local signer, then submit source verification to Blockscout. The deploy is recorded in your project.

How signing works#

Daemon generates a local EVM wallet whose private key is encrypted with the operating system keyring, the same custody model as the Solana wallet. The key is never displayed, exported, or written to a project, and the build tool only ever compiles. Deployment is testnet only in this release; mainnet is disabled until it has the same approval controls as the Solana surfaces.

Build your first contract#

Ask ARIA to scaffold a Robinhood Chain project, or run the rh_scaffold_contract tool.
Create the EVM wallet and fund it from the testnet faucet.
Build the contract with a pinned compiler.
Deploy to testnet (chain 46630) and read back the deployed address.
Submit source verification to Blockscout.

Building with stock tokens#

Robinhood's stock tokens are composable ERC-20s with Chainlink price feeds, so a contract can read a reported price on chain. The scaffold includes a reader that fetches the latest answer and rejects stale or non-positive values.
