Program Overview

AlphaWallet is the only self-custodial wallet that's 100% open source, forked more than 550 times since 2018. Production ready, simply customize for your tokens and launch your MVP in 1/5 of the time. Built by web3 engineers, for the community.

It is the first NFT wallet and the first mobile wallet to use on-device Secure Enclave. It remains the only 100% open source wallet.

Our ambition is for AlphaWallet to become a super User Agent that manages your identity: who you are, what you have and what you do. It will be your bridge to everything in Web3 and beyond.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.1. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.

All web/app bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required.

Payouts are handled by the AlphaWallet team directly and are denominated in USD. However, payouts are done in USDT.

Assets in scope

All web/app of AlphaWallet can be found at https://github.com/alphawallet. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

If an impact can be caused to any other asset managed by AlphaWallet that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project. This applies to only Critical and High impacts.

Impacts in scope

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

Websites and Applications

Out of Scope & Rules

The following vulnerabilities are excluded from the rewards for this bug bounty program:

  • Attacks that the reporter has already exploited themselves, leading to damage
  • Attacks requiring access to leaked keys/credentials
  • Attacks requiring access to privileged addresses (governance, strategist)

Websites and Apps

  • Theoretical vulnerabilities without any proof or demonstration
  • Attacks requiring physical access to the victim device
  • Attacks requiring access to the local network of the victim
  • Reflected plain text injection ex: url parameters, path, etc.
    • This does not exclude reflected HTML injection with or without javascript
    • This does not exclude persistent plain text injection
  • Self-XSS
  • Captcha bypass using OCR without impact demonstration
  • CSRF with no state modifying security impact (ex: logout CSRF)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”) without demonstration of impact
  • Server-side non-confidential information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used only to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Feature requests
  • Issues related to the frontend without concrete impact and PoC
  • Best practices issues without concrete impact and PoC
  • Vulnerabilities primarily caused by browser/plugin defects
  • Leakage of non sensitive api keys ex: etherscan, Infura, Alchemy, etc.
  • Any vulnerability exploit requiring browser bugs for exploitation. ex: CSP bypass

The following activities are prohibited by this bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
  • Any testing with pricing oracles or third party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
