Secure, audited smart contracts that power your Web3 product, from concept to mainnet deployment.
We build production-ready smart contracts for ERC-20, ERC-721, ERC-1155, and custom protocols. Our process delivers audit-ready code in 2-4 weeks, using battle-tested patterns from OpenZeppelin and rigorous internal review.
Deploy with confidence, backed by formal verification and gas optimization.
CertiK or Halborn conduct final audits.ABIs, deployment scripts, and frontend SDKs (ethers.js/web3.py) for seamless integration.Our oracle delivers verifiable, privacy-first compliance checks directly to your smart contracts, eliminating manual processes and reducing risk.
Automated, on-chain screening against global sanctions lists (OFAC, UN, EU) and Politically Exposed Persons (PEP) databases. Updates propagate in under 5 minutes, ensuring your protocol remains compliant with evolving regulations.
Users prove KYC/AML status without revealing personal data. Our oracle verifies ZK proofs from certified providers (e.g., Worldcoin, Polygon ID), enabling private, compliant transactions. Built with Circom and Halo2 for optimal verification gas costs.
Configurable risk models that analyze transaction patterns, wallet history, and jurisdictional data. Assign risk scores (0-1000) to addresses, enabling tiered access controls and automated alerts for high-risk activity directly within your dApp logic.
A unified, portable compliance record that follows user addresses across EVM and non-EVM chains (Solana, Cosmos). A 'Pass' on Ethereum is recognized on Polygon or Arbitrum, preventing regulatory arbitrage and simplifying user onboarding.
Every oracle response and risk assessment is immutably logged on a private, permissioned ledger (Baseline, Hyperledger). Provides regulators and auditors with a tamper-proof record of all compliance decisions for simplified reporting.
Guaranteed 99.95% uptime SLA with multi-region failover. Real-time monitoring, alerting, and dedicated support for critical incidents. Our infrastructure is certified SOC 2 Type II compliant and undergoes regular penetration testing.
Our privacy-preserving KYC/AML oracle delivers concrete, auditable advantages that accelerate your go-to-market and build user trust.
Integrate our API to verify users in under 2 seconds, reducing drop-off rates by up to 70%. No manual document uploads or waiting periods.
Automated, tamper-proof compliance logs for auditors. Our system is built to meet global standards including FATF Travel Rule and EU's MiCA regulations.
Verify user credentials without exposing sensitive PII. We use zk-SNARK proofs to confirm AML status, keeping your platform and users' data private.
Eliminate the cost of manual review teams and third-party vendor fees. Our automated oracle slashes compliance overhead by over 80%.
Single API for 150+ countries with localized sanction lists and watchlists. We handle regulatory fragmentation so you can scale globally.
Institutional-grade compliance attracts larger investors and higher-value users. Demonstrate provable safety to partners and VCs.

Security & Audit Overhead | High (unaudited, custom risk) | Low (pre-audited, battle-tested) |
Compliance Expertise Required | Must hire/develop in-house | Included (FINTRAC, FATF, Travel Rule) |
Supported Jurisdictions & Schemas | Limited to internal research | 30+ jurisdictions, 100+ ID schemas |
Integration Complexity | High (custom API, ZK circuits) | Low (standardized APIs, SDKs) |
Uptime & Reliability SLA | Your responsibility | 99.9% with financial backing |
Feature Updates (Sanctions, PEPs) | Manual, lagging updates | Automated, real-time updates |
Team Focus | Diverted to compliance infra | Freed for core product innovation |
A structured, security-first approach to integrating privacy-preserving KYC/AML, designed for rapid deployment and regulatory confidence.
We begin with a deep-dive analysis of your target jurisdictions, user flows, and data requirements. This phase defines the optimal privacy model (ZK-proofs, MPC, selective disclosure) and integration architecture, ensuring regulatory alignment from day one.
Our team builds the core infrastructure: the off-chain oracle for credential verification and the on-chain smart contracts for attestation management. All code follows OpenZeppelin standards and is optimized for gas efficiency and security.
Every component undergoes mandatory internal and external security reviews. We partner with leading firms like Trail of Bits and CertiK for formal verification of cryptographic circuits and smart contract logic before any deployment.
We deploy to a testnet environment first, supporting your team through end-to-end integration testing. Following sign-off, we manage the mainnet deployment with zero-downtime strategies and provide comprehensive monitoring dashboards.
Secure, production-ready smart contracts built for speed, scale, and compliance.
We architect and deploy custom smart contracts that form the secure backbone of your Web3 application. Our process delivers audit-ready code from day one, ensuring your core logic is robust and resilient.
ERC-20, ERC-721, ERC-1155, and ERC-4626 vaults with advanced features like minting controls and royalty enforcement.AMMs), staking pools, governance modules, and multi-signature treasuries.We deliver a fully tested, documented, and deployable contract suite in as little as 2-4 weeks, accelerating your path to mainnet launch.
Get clear answers on how our zero-knowledge KYC/AML oracle integrates with your DeFi or on-chain finance application.
Our oracle acts as a secure bridge between off-chain identity verification and on-chain applications. Users submit KYC data to our certified, non-custodial verification partner. Upon successful verification, the oracle mints a zero-knowledge proof (ZKP) credential (e.g., a Semaphore identity or zk-SNARK proof) to the user's wallet. Your smart contract can then query our oracle to verify the proof's validity without ever seeing the underlying personal data. This ensures compliance while preserving user privacy.
