CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
From tokenomics to governance, we translate your business rules into immutable, efficient code.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and staking logic. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, yield aggregators, and derivative contracts.
- Enterprise Logic: Multi-signature wallets, access control systems, and compliant KYC/AML modules.
- Full Audit Trail: Comprehensive unit, integration, and scenario testing with tools like Hardhat and Foundry.
We deliver production-ready contracts with detailed documentation, enabling your team to iterate and scale with confidence. Our focus is on security, gas efficiency, and upgradability from day one.

PROVEN PROCESS
Our Payment Gateway Audit Methodology
Our structured, multi-layered audit approach is designed to identify critical vulnerabilities in payment gateway smart contracts, ensuring financial security and operational resilience before mainnet deployment.
03
Manual Code Review & Logic Testing
Our senior auditors conduct line-by-line manual review and write custom test cases to uncover complex business logic flaws, edge cases in payment routing, fee calculations, and withdrawal patterns that automated tools miss.
04
Economic & Incentive Analysis
We simulate tokenomics, fee structures, and staking/reward mechanisms to identify potential for economic exploits, flash loan attacks, or incentive misalignment that could destabilize the payment system.
05
Formal Verification & Specification Checking
For critical payment functions, we use formal methods to mathematically prove the contract behaves as specified, ensuring absolute correctness for core operations like fund settlement and balance tracking.
06
Remediation & Final Verification
We provide a prioritized vulnerability report with actionable fixes and conduct a final verification audit on the updated code, delivering a certification seal for contracts that pass all security checks.

FOUNDATION
Custom Blockchain Development
Build secure, scalable blockchain networks tailored to your specific business logic and performance requirements.
We architect and deploy purpose-built blockchain solutions, from private consortium chains to high-throughput public network integrations. Our approach delivers production-ready infrastructure in weeks, not months.
- Custom Consensus & Architecture: Design networks with
Tendermint,IBFT, orHotStuffconsensus for your specific trust model and finality needs. - Smart Contract Layer: Develop and audit core business logic in
Solidity,Rust (Solana), orMove (Aptos/Sui). - Node Infrastructure: Provision and manage validator nodes with 99.9% uptime SLAs, automated monitoring, and key management.
We focus on the core protocol so you can focus on your product. Get a fully documented, audited mainnet launch without building an internal blockchain team.

Frequently Asked Questions
Get clear answers about our specialized security audit process for payment and settlement systems.
We employ a hybrid methodology combining automated analysis, manual review, and formal verification. Every audit includes: 1) Static analysis with Slither and MythX for pattern detection. 2) Manual line-by-line review by two senior auditors focused on business logic, access control, and financial flows. 3) Scenario testing for edge cases like oracle failure, front-running, and gas optimization. 4) Formal verification for critical state transitions and mathematical correctness of payment calculations. This multi-layered approach has secured over $500M+ in payment volume across 30+ gateway projects.
