overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From tokenomics to governance, we translate your business logic into robust on-chain systems.
- Full-Stack Development:
ERC-20,ERC-721,ERC-1155, and custom standards with OpenZeppelin security patterns. - Security-First Process: Rigorous internal review, formal verification tools, and preparation for third-party audits by firms like CertiK or Quantstamp.
- Deployment & Management: End-to-end support from testnet (
Sepolia,Holesky) to mainnet deployment and upgrade management via Transparent Proxies.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to deploying a Confidential Payment Verification Oracle, designed to minimize risk and accelerate your time-to-market.
01
Architecture & Design Review
We analyze your existing payment flow and design a custom oracle architecture. This includes defining the zero-knowledge proof circuit logic, data attestation sources, and integration points with your smart contracts.
2-3 days
Design Sprint

Requirement Alignment
02
Secure Circuit Development
Our cryptographers implement the zk-SNARK or zk-STARK circuits in Circom or Halo2. Every circuit undergoes formal verification and peer review to ensure correctness and prevent logic vulnerabilities.

Frequently Asked Questions
Get clear answers about our process, security, and how our oracle service integrates with your payment infrastructure.
Our oracle acts as a secure bridge between your traditional payment rails (like Stripe, PayPal, or bank APIs) and your smart contracts. It listens for payment events, cryptographically verifies the transaction data off-chain, and submits a signed, zero-knowledge proof to your contract. This allows your dApp to trustlessly release digital assets or unlock services upon confirmed fiat payment, without exposing sensitive customer data on-chain.
