Alpen Labs Bug Bounty Program

Alpen gives developers the freedom to program nearly any locking conditions for BTC imaginable, limited only by the Alpen block size and gas limits. This enables developers to create new kinds of applications for BTC with features such as:

• New signature types, "provide a valid P-256 signature to authorize a transfer"
• Vaults, "transfers must wait N days after being initiated to be effectuated, and can be cancelled in the mean time"
• Subscriptions, "address 0x123...9a can withdraw up to v BTC per month from this account"
• Strong privacy, "transaction details are end-to-end encrypted and verified using a zero-knowledge proof"
• Economically secured zero-confirmation payments, "if a double-spend from this sender is reported, the reporter gets to claim the sender's full wallet balance"
• Financial transactions, "if enough BTC is locked as collateral to maintain up to X% loan-to-value ratio, then up to Y of this other asset can be borrowed"

Rewards

Rewards by Threat Level

Smart Contract

• Critical: Up to $5,000
• High: Up to $2,000

Websites and Applications

• Critical: Up to $2,000
• High: Flat $1,000

Critical Reward Calculation

Mainnet assets: Reward amount is 10% of the funds directly affected up to a maximum of $5,000

Testnet assets: For critical smart contract bugs on testnet assets, the reward is paid as a flat amount of USD 2,500. For high level smart contract bugs on testnet assets, the reward is paid as a flat amount of USD 2,500.

Reward Payment Terms

Payouts are handled by the Alpen Labs team directly and are denominated in USD. Payments are done via wire transfer.

KYC Requirement

Alpen Labs will be requesting KYC information in order to pay for successful bug submissions. The following information will be required:

• Full name
• Date of birth
• Proof of address (either a redacted bank statement with address or a recent utility bill)
• Copy of Passport or other Government issued ID

Eligibility Criteria

Security researchers who wish to participate must adhere to the rules of engagement set forth in this program and cannot be:

• On OFAC's SDN list
• Official contributor, both past or present
• Employees and/or individuals closely associated with the project
• Security auditors that directly or indirectly participated in the audit review

Responsible Publication

Alpen Labs adheres to Category 3: Approval Required. This Policy determines what information researchers are allowed to make public from their submitted bug reports.

Primacy of Impact vs Primacy of Rules

Alpen Labs adheres to the Primacy of Rules, which means that the whole bug bounty program is run strictly under the terms and conditions stated within this page.

Proof of Concept (PoC) Requirements

A PoC, demonstrating the bug's impact, is required for this program and has to comply with the Immunefi PoC Guidelines and Rules. Proof of concept is always required for all severities.

Previous Audits

Alpen Labs's completed audit reports can be found at Project's Audits URL. Any unfixed vulnerabilities mentioned in these reports are not eligible for a reward.

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

Therefore, Immunefi has developed feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.

Prohibited Activities

• Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
• 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 that are executed against project assets
• Automated testing of services that generates significant amounts of traffic
• Public disclosure of an unpatched vulnerability in an embargoed bounty
• Any other actions prohibited by the Immunefi Rules
