Validator-Level Compliance Filtering
Integrate real-time sanctions screening directly into your validator node software. Reject non-compliant transactions at the consensus layer before they are included in a block, ensuring network-level compliance for Solana, Cosmos, and other PoS networks.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Custom Logic: From
ERC-20tokens andERC-721NFTs to complex DeFi primitives and DAO governance systems. - Security-First: Every contract undergoes internal review against OWASP Top 10 and common
reentrancy/overflowvulnerabilities before external audit. - Full Lifecycle: We handle development, testing (
Hardhat/Foundry), deployment, and verification on mainnet and L2s.
Deliver a secure, functional MVP in as little as 2-3 weeks, with guaranteed code ownership and comprehensive documentation.

ENTERPRISE-GRADE COMPLIANCE
Core Capabilities of Our Validator Filtering Solution
Our infrastructure-level filtering provides granular control over validator selection, enabling financial institutions to meet regulatory requirements without sacrificing performance or decentralization.
01
Jurisdictional Compliance Filtering
Automatically exclude validators based on geographic location, regulatory status, or OFAC sanctions lists. Ensure your transactions only route through compliant nodes.

Architectural Comparison
Validator-Level vs. Traditional Post-Hoc Screening
A technical breakdown of proactive, on-chain compliance at the validator layer versus reactive, off-chain screening methods.
| Compliance Factor | Traditional Post-Hoc Screening | Chainscore Validator-Level Filtering |
|---|---|---|
Enforcement Point | Off-chain, after transaction | On-chain, at consensus |
Prevention Capability | Reactive (block/reverse) | Proactive (prevent inclusion) |
Latency Impact | Adds 500ms - 2s per check | Negligible (<50ms) |
False Positive Rate | High (5-15%) due to lag | Low (<1%) with real-time data |
Coverage | Limited to monitored wallets | Network-wide for all validators |
Regulatory Audit Trail | Separate log system | Immutable, on-chain proof |
Implementation Time | 3-6 months integration | 4-8 weeks deployment |
Annual Operational Cost | $200K+ for data & team | $50K-$150K managed service |

Frequently Asked Questions on Validator Compliance
Get clear, technical answers on how our Validator-Level Compliance Filtering service integrates, scales, and secures your blockchain operations.
Our solution deploys as a middleware layer that sits between your consensus client and the network. We provide a lightweight SDK or a sidecar proxy that intercepts transactions before they are proposed in a block. Integration typically requires under 50 lines of code and does not require forking your node software. We support Geth, Erigon, Prysm, Lighthouse, and other major clients.
