Technical & Operational Comparison
Private Channels vs. Standard Cross-Chain Bridges
A detailed breakdown of how our private, off-chain payment channels differ from traditional on-chain bridges, highlighting key advantages for high-frequency, confidential transactions.
| Feature / Metric | Standard On-Chain Bridge | Chainscore Private Channel |
|---|---|---|
Settlement Mechanism | On-chain, per transaction | Off-chain netting, on-chain finality |
Transaction Privacy | Public ledger visibility | Private state between participants |
Cost per Transaction | $2 - $50+ (gas fees) | < $0.01 (off-chain) |
Settlement Speed | Minutes to hours (block times) | Sub-second (instant off-chain) |
Finality Guarantee | Probabilistic (awaiting confirmations) | Cryptographically guaranteed |
Supported Asset Types | Native tokens, basic ERC-20 | Native tokens, ERC-20, ERC-721, custom |
Operational Complexity | High (monitoring, gas management) | Low (managed service, automated) |
Ideal Use Case | Infrequent, large-value transfers | High-frequency, micro-payments, confidential B2B flows |
Time to Integrate | 2-4 weeks (DIY) | < 1 week (with our SDK) |
Security Model | Bridge contract risk (hack surface) | Peer-to-peer, reduced attack surface |

Frequently Asked Questions
Get clear answers on development timelines, security, costs, and support for your custom payment channel solution.
A standard implementation for a single asset pair (e.g., USDC/ETH) on two EVM chains takes 3-5 weeks from kickoff to mainnet deployment. Complex multi-asset, multi-chain systems with custom logic can extend to 8-12 weeks. This timeline includes design, development, internal testing, and a comprehensive third-party security audit.
