CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
Deliver a secure, functional MVP in as little as 2 weeks, not months.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with advanced features like vesting, staking, and governance. - DeFi Logic: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with sub-second finality.
- Security First: Every contract undergoes internal review against Common Weakness Enumeration (CWE) standards before external audit.

TURNING INFRASTRUCTURE INTO ADVANTAGE
Business Outcomes: From Cost Center to Competitive Edge
Integrating a cross-border payment oracle network is more than a technical upgrade. It's a strategic investment that transforms a back-office cost center into a powerful engine for growth, customer acquisition, and market leadership.
01
Slash Operational Costs by 70-90%
Replace manual FX reconciliation, correspondent banking fees, and legacy middleware with automated, on-chain settlement. We deliver direct integration to real-time FX rate oracles and liquidity pools, eliminating intermediary markups and manual processing overhead.

Cost Reduction
Zero
Correspondent Fees
02
Accelerate Settlement from Days to Seconds
Move from T+2 banking cycles to near-instant finality. Our integration leverages blockchain's native settlement layer, providing transparent, immutable transaction proof and freeing up capital trapped in transit.

Frequently Asked Questions
Get answers to common questions about integrating our secure, low-latency oracle network for real-time FX rates and payment settlement.
Standard integration for a single payment corridor (e.g., USD-EUR) takes 2-3 weeks from kickoff to production deployment. This includes smart contract development, data feed configuration, and security review. Multi-corridor or custom logic deployments typically require 4-6 weeks. We provide a detailed project plan during the initial technical consultation.
