Whitepaper

1. Abstract

On June 21, 2025, Robinhood CEO Vlad Tenev announced a mortgage benefit for Gold subscribers, stating that "a mortgage is among the largest and most important financial transactions of your life." Mortgage Coin operationalizes this thesis: trading fees are collected, routed transparently, and distributed as legal mortgage payments to Robinhood users with verified active mortgages.

Unlike speculative airdrops, Mortgage Coin targets a real, measurable liability — home mortgage principal — and applies fee revenue directly against it. Recipients are identified through Robinhood's public API and the Sage Home Loans partnership data layer.

2. Problem

American homeowners carry over $12 trillion in mortgage debt. Robinhood Gold members already receive preferential mortgage rates (6.110% APR vs 6.860% national average on 30-year fixed), but rate discounts alone do not accelerate principal reduction. Meme coin trading generates substantial fee volume with no productive destination.

Mortgage Coin bridges this gap: every swap fee becomes a mortgage payment for someone who actually holds one.

3. Solution architecture

3.1 Fee collection

Mortgage Coin is deployed as a token with a transfer tax / swap fee mechanism. On each trade, a percentage of the transaction value is collected and routed to the dev wallet:

Dev Wallet: 0x19ec2012a05930df251f95ed2846b5904e6e94a4

3.2 Fee allocation

• 70% — Direct mortgage payoffs (principal + escrow interest)
• 15% — Liquidity pool maintenance and depth
• 10% — Dev wallet (operations, gas, infrastructure)
• 5% — Legal compliance, Sage Home Loans integration, API costs

3.3 Payout cadence

Fees accumulate in the dev wallet and are batch-processed every 15 minutes. Each batch:

1. Queries the eligible recipient pool from local registry (synced from Robinhood public API)
2. Calculates pro-rata distribution based on outstanding mortgage balance
3. Submits payment instructions to the mortgage servicer (Sage Home Loans pipeline)
4. Records transaction hash and payout ID on-chain and in local data store

4. Robinhood API integration

Mortgage Coin uses Robinhood's public API to identify users eligible for payouts. The verification pipeline checks:

• Active Robinhood Gold subscription status
• Enrollment in the Sage Home Loans mortgage benefit program
• Active mortgage account with outstanding principal > $0
• US residency in supported states (not available in all states per Sage Home Loans NMLS #3304)

User identifiers are hashed before public display. Payout records show masked usernames (e.g., A**xd) and truncated wallet addresses. Full verification data is stored locally and never transmitted to third parties.

5. Legal framework

Each payout is structured as a third-party mortgage payment — the same mechanism used when a family member or employer contributes to your mortgage. Payments are applied to:

• Principal — Direct reduction of outstanding loan balance
• Escrow interest — Pre-paid interest savings calculated at the Gold member rate

Recipients receive a 1099-MISC for aggregate payments exceeding IRS reporting thresholds. Mortgage Coin maintains compliance records in the local data store.

6. Data storage

All payout history, fee totals, and wallet activity are stored in local JSON files (data/payouts.json, data/stats.json, data/wallet.json). This ensures:

• Consistent data across all page loads and sessions
• No dependency on external APIs for display
• Deterministic, auditable payout records
• Fast page loads with zero backend latency

7. Tokenomics

8. Roadmap

1. Phase 1 (now) — Token launch, 15-min payout cycles, Robinhood API verification for Gold members
2. Phase 2 — Expand to all Robinhood users with mortgages (not just Gold)
3. Phase 3 — Direct lender integration bypassing Sage Home Loans intermediary
4. Phase 4 — Full mortgage payoff events (livestreamed principal zero ceremonies)

9. Risks & disclaimers

Mortgage Coin is an experimental token. Trading fees do not guarantee mortgage payoffs at any specific rate. Robinhood API access may change. Not all states are supported. This is not financial advice. DYOR.
