We build custom smart contracts that power your Web3 product, from initial audit to mainnet deployment. Our process delivers gas-optimized, secure code with a focus on long-term maintainability.
Mobile Remittance Smart Contract Audit & Development
Smart Contract Development
Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.
- DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators, and automated market makers (AMMs).
- NFT Ecosystems: ERC-721A, ERC-1155 marketplaces, dynamic metadata, and royalty engines.
- Enterprise Solutions: Supply chain tracking, tokenized assets, and custom
ERC-20implementations.
Every contract undergoes rigorous security review using static analysis, formal verification, and testnet simulation before launch.
Deliverables include: comprehensive audit reports, deployment scripts, and documentation. We ensure your contracts are upgradeable and compliant with the latest EIP standards.
Core Smart Contract Capabilities We Deliver
Our mobile remittance smart contracts are engineered for security, compliance, and seamless cross-border transactions. We deliver battle-tested code that meets the rigorous demands of financial applications.
Cross-Chain Settlement Contracts
Deploy secure bridging and atomic swap logic for multi-asset transfers across Ethereum, Polygon, and BNB Chain. Reduce settlement latency and eliminate single-chain dependency.
Compliant Transaction Logic
Integrate automated regulatory checks (AML/CFT), transaction limits, and jurisdiction-based rules directly into contract logic. Ensure compliance without sacrificing user experience.
Gas-Optimized Payment Routing
Implement efficient fee calculation and dynamic routing algorithms to minimize transaction costs for end-users, crucial for micro-remittances and high-frequency transfers.
Multi-Signature Treasury & Escrow
Secure fund management with customizable M-of-N signature schemes and time-locked escrow releases. Provide operational security and fraud prevention for pooled liquidity.
Upgradable Architecture & Emergency Controls
Deploy using proxy patterns (UUPS/Transparent) with secure upgrade mechanisms and emergency pause functions. Ensure long-term maintainability and rapid response capability.
Why Choose Chainscore for Your Remittance Contracts
We deliver secure, compliant, and scalable smart contract infrastructure for global remittance platforms. Our focus is on reducing your technical risk and accelerating your time-to-market.
Specialized Cross-Chain Architecture
We build remittance contracts optimized for interoperability across EVM chains (Polygon, Arbitrum, Base) and Layer 2s, ensuring low-cost, fast settlement for end-users.
Security-First Development & Audits
Every contract undergoes rigorous internal review and formal verification. We provide a comprehensive audit report and remediation support before mainnet deployment.
Regulatory Compliance Built-In
Incorporate travel rule (FATF), sanctions screening, and transaction monitoring logic directly into your contract architecture to meet global compliance standards.
Proven Deployment Framework
Leverage our battle-tested deployment pipeline with multi-sig governance, upgradeability patterns, and emergency pause mechanisms for secure, controlled launches.

Our Security-First Development & Audit Process
From initial architecture to post-deployment monitoring, our end-to-end process is designed to eliminate vulnerabilities and ensure regulatory compliance for cross-border payments.
Architecture & Threat Modeling
We begin with a formal threat model, identifying attack vectors specific to remittance flows, multi-signature wallets, and compliance checks before a single line of code is written.
Secure Development with Formal Verification
Contracts are built in Solidity 0.8+ using OpenZeppelin libraries. Critical logic for fund routing and fee calculations is formally verified using tools like Certora and Slither to prove correctness.
Multi-Layer Security Audits
Every contract undergoes automated analysis, manual review by senior auditors, and a final review focused on financial logic, oracle security, and regulatory hooks (e.g., OFAC sanctions).
Gas Optimization & Cost Analysis
We optimize for low transaction costs—critical for micro-remittances. Every function is benchmarked, with detailed reports on gas usage for transfers, compliance checks, and batch operations.
Deployment & Incident Response
We manage secure multi-sig deployments on mainnet and testnets, establish monitoring with real-time alerts for anomalous flows, and provide a documented incident response plan.
Compliance & Regulatory Readiness
Build with embedded hooks for travel rule compliance (e.g., TRP), sanctions screening, and transaction limits. Our contracts are designed to integrate with traditional KYC/AML providers.
Protocols & Standards We Build With
Our mobile remittance solutions are built on battle-tested standards and audited by industry leaders, ensuring secure, compliant, and cost-effective cross-border transactions.
Compliance & Regulatory Frameworks
Build with Travel Rule (TRP) protocols and embedded regulatory checks. Our contracts support modular compliance modules for different jurisdictions (FATF, MiCA).
Payment Channel Networks
Implement state channels for instant, high-volume micro-payments. Ideal for remittance corridors requiring sub-second finality and negligible fees for repeat transactions.
Frequently Asked Questions

Our process follows a structured 4-phase approach: 1) Discovery & Scoping (1 week): We analyze your requirements, tokenomics, and target chains. 2) Architecture & Development (2-4 weeks): Our team builds the contracts using Solidity 0.8+ with OpenZeppelin libraries, implementing features like multi-currency support and compliance hooks. 3) Comprehensive Audit (1-2 weeks): Our in-house security team conducts manual review and automated testing (Slither, MythX). 4) Deployment & Support: We assist with mainnet deployment and provide 90 days of bug-fix support. This ensures a predictable path from concept to live protocol.
