PROVEN PROCESS
Our Delivery Methodology
A structured, security-first approach to building and deploying confidential cross-border payment rails. We deliver production-ready systems, not just prototypes.
01
Architecture & Protocol Design
We design your confidential payment rail using battle-tested zero-knowledge proofs (zk-SNARKs, zk-STARKs) and privacy-preserving protocols like Aztec or Zcash Sapling. This ensures transaction amounts and counterparty details remain encrypted on-chain.
2-3 weeks

On-Chain Privacy
02
Smart Contract Development & Audit
Our engineers write production-grade Solidity/Vyper contracts for settlement and compliance logic. Every line of code undergoes internal review followed by a formal audit from a top-tier firm like Trail of Bits or Quantstamp before deployment.

0 Critical
Guaranteed Post-Audit
03
Integration & Oracles
We seamlessly integrate your system with critical external data. This includes secure FX rate oracles (Chainlink), compliance verification modules for AML/KYC, and connections to traditional banking APIs (SWIFT, SEPA) via licensed partners.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy mission-critical smart contracts on EVM and Solana. Every contract undergoes a rigorous security-first development cycle, including internal audits, formal verification, and integration with leading audit firms like CertiK and Quantstamp.
- Custom Logic: Build bespoke DeFi primitives, NFT mechanics, DAO governance, or enterprise-grade asset tokenization.
- Gas Optimization: Achieve up to 40% lower transaction costs through expert
Solidity/Rustoptimization. - Full Lifecycle: From initial spec and
OpenZeppelinintegration to mainnet deployment and upgrade management viaProxypatterns. - Compliance Ready: Implement
ERC-20,ERC-721,ERC-1155with modular features for regulatory requirements.
Deploy a secure, audited MVP in as little as 2 weeks, backed by a 99.9% uptime SLA for live contracts.

Frequently Asked Questions
Get clear answers on how we build secure, compliant, and high-performance payment rails for your business.
We architect systems using zero-knowledge proofs (like zk-SNARKs) and confidential assets to encrypt transaction amounts and counterparties on-chain. Our legal team provides a compliance-by-design framework, integrating KYC/AML checks via modular, non-custodial services (e.g., identity verification oracles) before funds enter the private payment channel. This ensures full auditability for regulators without exposing sensitive commercial data on the public ledger.
