Anonymous Reputation & Soulbound Token (SBT) Architecture

We design and implement systems where user reputation is privately accumulated and verified via zero-knowledge proofs. Enable trust and access control without exposing personal identity or history.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, and NFT platforms. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security from day one. Deliverables include full technical specifications, gas-optimized code, and comprehensive test suites.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 with minting, vesting, and governance modules.
  • DeFi Logic: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing protocols.
  • Enterprise Features: Upgradeability via proxies, multi-signature admin controls, and compliance hooks for regulatory requirements.
  • Full Audit Support: Code is structured for seamless review by firms like CertiK or Trail of Bits.

We deliver a production-ready MVP in 2-4 weeks, backed by a 99.9% uptime SLA for deployed contracts. Our focus is on eliminating vulnerabilities and reducing time-to-market for your core product.

Core Architecture Components We Deliver

We build the modular, secure, and scalable infrastructure that powers your on-chain reputation and identity systems. Each component is production-ready, audited, and designed for seamless integration.

01

Soulbound Token (SBT) Smart Contracts

Custom ERC-721 and ERC-1155-based SBTs with non-transferability enforcement, revocation logic, and on-chain metadata attestations. Built with OpenZeppelin standards and gas-optimized for high-volume minting.

02

Anonymous Reputation Aggregator

Zero-Knowledge (ZK) circuits and verifiers that compute reputation scores from private inputs (e.g., transaction history, credentials) without exposing underlying data. Enables privacy-preserving user verification.

Reputation Oracle & Data Feeds

Secure oracles that fetch, compute, and deliver verifiable off-chain data (social, DeFi, DAO activity) to smart contracts. Includes fraud-proof mechanisms and decentralized node operators.

Access Control & Permission Layer

Flexible rule engine for gating actions (minting, voting, access) based on SBT holdings or reputation scores. Implements role-based (RBAC) and attribute-based (ABAC) access patterns.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, security-first approach to architecting and deploying your on-chain reputation layer. We deliver production-ready systems, not just prototypes.

01

Architecture & Design Review

We analyze your use case to design a custom SBT and reputation model. This includes selecting the optimal standard (ERC-721, ERC-1155, or custom), defining attribute schemas, and mapping privacy requirements to zero-knowledge proofs or selective disclosure patterns.

Frequently Asked Questions

Get clear answers on how we design and implement privacy-first, verifiable identity systems for Web3 applications.

A standard implementation takes 4-8 weeks from initial design to mainnet deployment. This includes a 1-week discovery phase, 2-3 weeks for smart contract development and testing, 1-2 weeks for integration with your frontend, and a final week for security audits and deployment. Complex systems with custom zero-knowproof circuits or multi-chain attestations may extend to 12 weeks.
