Why a generic solution fails for tokenized assets
Generic Custody vs. Chainscore's AppChain-Native Approach
Traditional custody services treat all assets the same, creating friction and risk for Real-World Asset (RWA) tokenization. Our approach is engineered specifically for the unique compliance, settlement, and operational needs of your application-specific blockchain.
| Custody Capability | Generic Multi-Chain Custody | Chainscore AppChain-Native Custody |
|---|---|---|
Native Asset & Protocol Support | Limited to major chains (ETH, SOL) | Full support for your custom AppChain & token standards |
Compliance & Legal Settlement Integration | Manual, off-chain processes | Programmable, on-chain settlement with legal attestation hooks |
Time to Integrate Custody | 3-6 months for custom logic | 4-8 weeks with our SDK and pre-built modules |
Transaction Finality for Settlements | Variable (mins to hours) | Sub-2 seconds on your dedicated chain |
Audit Trail & Proof of Reserve | Basic, aggregated reporting | Real-time, per-asset cryptographic proof on-chain |
Smart Contract Risk | High (uses generic, unaudited adapters) | Low (uses audited, chain-specific modules) |
Developer Experience (DX) | Complex API wrappers & workarounds | Native SDKs and direct chain interaction |
Total Cost of Ownership (Year 1) | $200K+ in dev & integration time | $50K-$150K all-in managed service |

STRUCTURED DEPLOYMENT
Our Delivery Process: From Architecture Review to Mainnet
A proven, phased approach to deliver secure, compliant, and production-ready RWA custody infrastructure for your application-specific blockchain.
01
Phase 1: Architecture & Compliance Review
We conduct a deep-dive technical and regulatory assessment of your AppChain's RWA use case. We map asset types, define custody models (self-custody, multi-sig, MPC), and establish a compliance-first technical blueprint.
Deliverable: A detailed architecture document and compliance gap analysis report.
2-3 weeks

Frequently Asked Questions for AppChain RWA Custody
Get clear answers on timelines, security, integration, and support for our AppChain-specific custody solutions.
Standard integration takes 2-4 weeks from kickoff to production-ready deployment. This includes smart contract deployment, API integration, and security review. Complex tokenization logic or custom compliance modules can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
