Public-facing web interfaces, documentation portals, the testnet faucet, and the mainnet block explorer.

Special Focus Areas

  • SSRF / RCE on the faucet backend
  • Subdomain takeover on *.chain.robinhood.com
  • Stored or reflected XSS via Robinhood Chain data on the explorer or public pages

Block Explorer

robinhoodchain.blockscout.com is in scope for Robinhood-specific issues only - for example stored or reflected XSS via Robinhood Chain data, or misconfiguration of the Robinhood instance. Vulnerabilities in core Blockscout software belong to Blockscout's own program.

Mainnet vs. Testnet

Mainnet (*.mainnet.chain.robinhood.com, chain ID 4663) is full severity. A testnet finding (chain ID 46630) that is reproducible on mainnet is full severity - demonstrate the mainnet vector rather than exploiting production. Testnet-only findings are discretionary.

Rewards are proposed maximums pending final Robinhood sign-off. Actual payouts are at Robinhood's discretion based on report quality, completeness, and exploitability.

Out of scope

The following issues are out of scope and not eligible for rewards.

For generic exclusions, see the Cantina Bug Bounty Out-of-Scope Policy.

L2 / Chain-Specific

  • The Arbitrum node software (Nitro and ArbOS) and the sequencer, public RPC, and feed endpoints that run it. Robinhood Chain is an Arbitrum chain; protocol-level bugs in this software are covered by Arbitrum's bug bounty program.
  • Validator software and operations (operated by Offchain Labs and Alchemy)
  • Internal sequencer infrastructure not reachable from public endpoints
  • Generic DDoS (amplification, reflection, flooding) that does not exploit protocol- or implementation-specific weaknesses
  • Theoretical transaction censorship by a small group of operators absent a demonstrated financial-impact path
  • Improperly configured nodes (node operator responsibility)
  • Hardware below recommended specs (node operator responsibility)
  • Local attacks against nodes requiring prior access to that node
  • Statesync peers are assumed trusted; findings against a malicious statesync peer are out of scope

Third-Party Code (report to the respective program)

  • Vulnerabilities in third-party protocols themselves (LayerZero core, etc.)
  • The Chainlink Data Streams aggregator and node operators, and incorrect data from third-party oracles in and of itself
  • Arbitrum-authored contract code for the canonical bridge / rollup (OCL / Arbitrum's program)
  • Core Blockscout software (Blockscout's program)
  • Alchemy's RPC, Data API, and account-abstraction (gasless transaction) infrastructure, including its bundler and paymaster.
  • Issuer-owned bridged token contracts (for example, USDG from the Global Dollar Network) and the third-party bridge paths that carry them.
  • Third-party applications, protocols, and infrastructure built on or integrated with Robinhood Chain, including the partners listed under the Ecosystem section of our About Robinhood Chain page.

Robinhood-Specific

  • Any repo, site, service, product, API, or resource not listed in the in-scope groups above
  • Robinhood's traditional brokerage / equities platform (this program covers Robinhood Chain and crypto products only)
  • Findings on Robinhood assets outside this program's scope belong in Robinhood's main bug bounty program; report them at robinhood.com/us/en/support/articles/report-security-vulnerabilities
  • Internal Robinhood infrastructure not reachable from public networks (corporate VPNs, internal monitoring, CI/CD)
  • Social engineering, physical attacks, attacks on Robinhood employees
  • Vulnerabilities requiring access to a user's device, account credentials, or 2FA
  • Findings reported to Robinhood through other channels prior to or concurrent with this program
  • Best-practice recommendations with no demonstrated exploit path

Default Out of Scope
