We specialize in a range of contract types to meet your specific needs:
- Tokens: Custom
ERC-20,ERC-721, andERC-1155implementations. - DeFi: Automated Market Makers (AMMs), lending/borrowing pools, and staking contracts.
- Governance: DAO frameworks with proposal and voting mechanisms.
- Utility: Access control, vesting schedules, and multi-signature wallets.
Privacy-Preserving Staking
Frequently Asked Questions
Common questions from CTOs and technical founders evaluating our identity layer for institutional staking and DeFi.
We implement a zero-knowledge proof (ZKP) system, typically using Circom and Halo2, that allows validators to prove their eligibility and reputation without revealing their on-chain addresses or staking history. The core is a verifiable credential system where identity attestations (like KYC/AML status or institutional accreditation) are issued off-chain and proven on-chain via ZK-SNARKs. This enables private participation in slashing committees, governance, and whitelisted pools.
