Project Overview

We are seeking a qualified developer or development team to design and build a Bitcoin Retirement Calculator for our website. The calculator should help users explore how their Bitcoin holdings, future contributions, and retirement goals may affect their long-term financial outlook.

Access must be restricted exclusively to verified holders of the COMPLIANCE TOKEN. Wallet connection and token ownership verification are mandatory components of this project.

Mockup

Scope and Requirements

1. Retirement Calculator

Users should be able to enter and adjust:

• Current age and target retirement age.
• Current Bitcoin holdings.
• Planned monthly contributions in USD.
• Assumed annual Bitcoin price growth.
• Desired annual retirement spending.
• Inflation assumptions and retirement duration.

Results should include projected Bitcoin holdings and USD value at retirement, estimated retirement funding surplus or shortfall, and how long holdings may support the selected spending level. Provide clear charts and conservative, moderate, and aggressive scenarios with editable assumptions.

Calculation methodology and assumptions must be documented. Projections must be clearly labeled as hypothetical and include an appropriate financial-information disclaimer.

2. Mandatory COMPLIANCE TOKEN Verification

Only users holding the required COMPLIANCE TOKEN balance may use the calculator.

The solution must:

• Include a wallet connector compatible with the token’s blockchain and relevant wallets.
• Require a signed message to confirm control of the connected wallet.
• Verify token ownership against the designated token contract or asset identifier.
• Enforce access through server-side verification or an equivalent secure mechanism. Hiding the calculator in the interface alone is insufficient.
• Revalidate eligibility when a session begins, when the connected wallet changes, and periodically during active use.
• Deny access when ownership cannot be verified or the required balance is no longer held.
• Display clear instructions for connecting a wallet and explaining eligibility.

Wallet verification must not require private keys, seed phrases, token transfers, or spending approvals. Token network, contract or asset identifier, and minimum qualifying balance will be confirmed before development.

3. Website Integration and Design

• Integrate with our existing website and branding.
• Provide a professional, responsive experience on desktop and mobile.
• Include clear loading, error, wallet connection, and access-denied states.
• Allow authorized administrators to update default assumptions and token eligibility settings.
• Minimize collection and retention of wallet and financial-input data.

Deliverables

• Completed calculator and wallet verification integration.
• Deployment to a staging environment and our production website.
• Source code and setup documentation.
• Documentation of calculation methodology, third-party services, and recurring costs.
• Testing covering calculation accuracy, mobile usability, wallet verification, and unauthorized access attempts.
• At least 30 days of post-launch bug support.

Proposal Submission

Please include:

• Relevant examples of calculator development and wallet integrations.
• Proposed technical approach and supported wallets.
• Estimated timeline and key milestones.
• Fixed project fee or itemized estimate.
• Expected hosting, blockchain-data, and maintenance costs.
• Assumptions, dependencies, and information required from our team.

Acceptance Criteria

The project will be accepted when the calculator produces results consistent with the agreed methodology, functions across supported devices, and reliably restricts calculator functionality to verified COMPLIANCE TOKEN holders. Direct requests that bypass the wallet verification flow must be rejected.

Proposals will be evaluated on relevant experience, security approach, usability, delivery timeline, and total cost.
