As financial institutions increasingly adopt digital settlement and on-chain liquidity, the success of implementation hinges on secure and seamless technical integration. The SGChain Banking Technical Integration Blueprint provides a clear, institution-ready framework, demonstrating how traditional bank systems can connect safely with the SGChain ecosystem—without disrupting existing operations.
Built specifically for regulated banks and financial institutions, this blueprint prioritizes architectural clarity, compliance alignment, and operational reliability.
A Secure Bridge Between Banks and SGChain
At the heart of integration is a structured architecture linking a bank’s internal systems with the SGChain network via the SGChain Banking Gateway. This architecture connects:
- Bank Core Systems: custody cores, payment switches, and core banking infrastructure
- SGChain Banking Gateway: AML/KYT engines, fiat pools, and compliance controls
- SGChain Node: settlement, minting, and burn execution
This design ensures controlled, compliant communication between traditional banking infrastructure and on-chain settlement rails.
Dual-Rail Settlement Pipeline
SGChain uses a dual-rail settlement approach that separates fiat operations from blockchain responsibilities:
Bank Fiat & Settlement Rail
Handles fiat transactions using traditional rails such as RTGS, ACH, SWIFT, and local payment networks.
SGChain Settlement Rail
Manages on-chain token operations, including minting, burning, and liquidity vault management.
This separation allows banks to maintain complete control over fiat operations while leveraging blockchain efficiency for settlement processes.
Mint and Burn Transaction Lifecycle
SGChain defines a clear lifecycle for moving value between fiat and SGCoin:
Fiat to SGCoin (Mint)
Banks initiate transfers from regulated accounts, perform KYC/KYT checks, and mint SGCoin into SGChain liquidity pools after validation.
SGCoin to Fiat (Burn)
Tokens are burned on-chain, liquidity pools reconciled, and fiat settlement completed through standard banking rails.
This lifecycle ensures traceability, compliance, and settlement finality at every step.
API-Driven Bank Integration
SGChain provides structured, institution-ready API endpoints that enable banks to:
- Mint and deposit SGCoin securely
- Burn and withdraw SGCoin back to fiat
- Receive real-time updates via webhooks for minting, settlement, and reconciliation events
API-driven integration allows seamless automation while maintaining full audit visibility.
Embedded Compliance by Design
Compliance is integrated into every layer of SGChain’s architecture. Key compliance outputs include:
- Full AML and KYT screening
- Wallet and address risk monitoring
- FATF Travel Rule–aligned transaction packaging
Onboarding, transaction monitoring, and enforcement are managed through a combination of bank controls and SGChain compliance engines, ensuring regulatory adherence at all times.
Ledger and Reconciliation Model
SGChain provides a clear ledger structure to support audit and reconciliation:
- Bank-ledger accounts act as primary fiat clearing accounts
- SGChain fiat accounts serve as settlement counterparts
- Reconciliation is performed daily using transaction hashes, batch IDs, and integrity checks
This framework ensures full transparency across banking and blockchain records.
Risk Controls and Security Framework
SGChain incorporates multiple safeguards to protect institutional operations:
Risk Controls:
- Transaction ceilings
- Velocity checks to monitor transaction frequency and volume
- Multi-signature treasury controls
- Circuit breakers to prevent abnormal flow or peg deviations
Security Measures:
- Encrypted key storage
- Tamper-evident logging
- On-chain proof-of-reserves
- Audit-ready reporting
These measures protect banks while maintaining operational efficiency.
Sandbox Testing and Certification
Before going live, banks undergo a structured readiness process:
- Pre-integration technical review
- Sandbox testing for mint, burn, and stress scenarios
- Controlled deployment with monitoring and failover
- Final certification and regulatory sign-off
This phased approach minimizes operational risk and accelerates readiness for production.
Teams Required for Integration
Successful integration requires collaboration across key functions:
- Core banking and treasury teams
- Compliance and AML units
- Risk, payments, and cybersecurity teams
Coordination ensures alignment across technical, regulatory, and operational domains.
Conclusion
The SGChain Banking Technical Integration Blueprint provides a clear, structured, and institution-ready framework for connecting traditional banks to on-chain settlement infrastructure. Through secure architecture, embedded compliance, robust risk controls, and phased deployment, SGChain enables banks to adopt blockchain settlement confidently.
Rather than disrupting existing banking systems, this blueprint strengthens them—creating a compliant, auditable, and scalable bridge between traditional finance and next-generation digital settlement.
If you want, I can also create a matching cover image for this technical integration blog just like the previous SGChain blog covers.
