Infrastructure Comparison
SBT-Gated vs. Traditional Collateral Rental
A technical and operational comparison between modern SBT-based access control and legacy collateral models for rental marketplaces.
| Feature | Traditional Collateral | SBT-Gated Access |
|---|---|---|
Onboarding Friction | High (Capital lockup, credit checks) | Low (Wallet connection, token verification) |
Default & Dispute Resolution | Manual, slow, legal overhead | Programmatic, automated via smart contract |
Liquidity Requirement | High (Collateral per rental) | Minimal to None |
User Experience | Cumbersome, multi-step | Seamless, self-custodial |
Fraud & Sybil Risk | Moderate (Fake IDs, chargebacks) | Low (On-chain reputation, non-transferable) |
Development Complexity | Medium (Integrate payment rails, escrow) | High (Requires SBT issuance & gating logic) |
Time to Integrate | 4-6 weeks | 2-3 weeks with our SDK |
Regulatory Surface | Large (Financial regulations apply) | Emerging (Focus on data/identity) |
Typical Implementation Cost | $75K - $150K+ | $25K - $60K with our templates |

Frequently Asked Questions
Common questions about implementing blockchain-based identity verification for rental properties.
A standard deployment for a single property or small portfolio takes 2-4 weeks from kickoff to production. Complex multi-chain integrations or large-scale property management platforms typically require 6-8 weeks. Our agile process includes a 1-week discovery phase to finalize your specific requirements before development begins.
