REVERSIBLE TRANSACTIONS INFRASTRUCTURE FOR WEB3
Production-ready. Seeking strategic investment.
REVERSO is the first non-custodial reversible transaction protocol for EVM chains. We solve a $3.8B annual problem: crypto transactions are irreversible, causing massive losses from mistakes, phishing, and fraud.
| Metric | Value |
|---|---|
| Problem Size | $3.8B+ lost annually |
| Solution | Time-locked reversible transfers |
| Product Status | MVP complete, 163 tests passing (131 Hardhat + 32 API) |
| Chains Supported | 7 live (ETH, BSC, Base, Arbitrum, Polygon, Optimism, Avalanche) |
| Revenue Model | 0.3-0.7% fees + 0.2% insurance + API subscriptions |
| Ask | $50,000 |
| Use | Security audit + enterprise partnerships + go-to-market |
Every blockchain transaction is final and irreversible. This creates massive friction:
| Problem | Annual Loss | Who Suffers |
|---|---|---|
| 🎣 Phishing & Scams | $3.8B | Retail users |
| 📝 Wrong Address | $1.2B | Everyone |
| 💀 Smart Contract Bugs | $1.5B | DeFi users |
| 🏢 Payroll Errors | $500M+ | Enterprises |
| TOTAL | $7B+ | The entire ecosystem |
For enterprises, this is unacceptable risk:
- Exchanges face chargebacks they can't reverse
- Payroll providers risk sending to wrong addresses
- E-commerce loses customers afraid of crypto payments
- DAO treasuries have no safety net
REVERSO introduces a non-custodial safety layer between sender and recipient:
┌─────────────────────────────────────────────────────────────────┐
│ REVERSO TRANSACTION FLOW │
├─────────────────────────────────────────────────────────────────┤
│ │
│ SEND ──▶ LOCK PERIOD ──▶ UNLOCK ──▶ CLAIM ──▶ COMPLETE │
│ │ │ │ │ │
│ │ [CANCEL OK] [RECIPIENT [DONE] │
│ │ CAN CLAIM] │
│ │ │
│ If cancelled → instant refund │
│ If unclaimed → auto-refund after expiry │
│ If all fails → rescue after 90 days │
│ │
│ 🛡️ 5 LAYERS OF PROTECTION: │
│ 1. Cancel during lock │
│ 2. Recovery Address 1 (hardware wallet) │
│ 3. Recovery Address 2 (exchange backup) │
│ 4. Auto-refund after expiry │
│ 5. Rescue abandoned funds (90 days) │
│ │
└─────────────────────────────────────────────────────────────────┘
Key Differentiators:
- Non-custodial: Funds stay in smart contract, not our wallets
- Configurable lock: 1 hour to 30 days
- Multi-chain: Same UX across 7 EVM chains
- Insurance option: +0.2% for full scam protection
- Enterprise API: HMAC-secured, rate-limited, webhook-enabled
| Pain Point | Without REVERSO | With REVERSO |
|---|---|---|
| Payroll errors | Lost funds, legal issues | Cancel within 24-72h |
| Customer refunds | On-chain = final | Built-in reversal window |
| Fraud protection | Accept loss | Insurance + cancel option |
| Compliance | Irreversible = risky | Audit trail + recovery |

| Stream | Rate | Projected Revenue* |
|---|---|---|
| Transaction Fees | 0.3-0.7% (progressive) | $5.8M/year @ $1B volume |
| Insurance Premiums | 0.2% on premium transfers | $600K/year |
| API Subscriptions | $99-$2,000/month | $600K/year |
| TOTAL | ~$7M/year |
*Projections based on capturing 0.1% of annual DeFi transaction volume
| Amount | Fee | Example |
|---|---|---|
| < $1,000 | 0.3% | $500 → $1.50 fee |
| $1K - $100K | 0.5% | $10,000 → $50 fee |
| > $100,000 | 0.7% | $1M → $7,000 fee |
Why progressive? Small users pay less (adoption), whales pay more (premium service).
| Segment | Size | REVERSO Position |
|---|---|---|
| Crypto transactions | $2T+/year | Safety layer |
| DeFi TVL | $50B+ | Recovery option |
| Crypto payroll | $500M+/year | B2B solution |
| E-commerce crypto | $100M+/year | Payment safety |
| Alternative | Problem | REVERSO Advantage |
|---|---|---|
