Strategic Comparison
Build vs. Buy: Custom Escrow vs. Generic Bridges
A detailed breakdown of the trade-offs between developing a custom cross-chain escrow solution in-house, using a generic bridge, or partnering with Chainscore for a custom-built service.

Frequently Asked Questions
Get clear answers on our development process, security, timelines, and support for building secure, multi-chain escrow solutions.
A standard cross-chain escrow deployment takes 4-8 weeks from kickoff to mainnet launch. This includes 1-2 weeks for architecture design and smart contract development, 2-3 weeks for rigorous internal testing and security audits, and 1-2 weeks for deployment and integration. Complex features like multi-asset support or custom dispute resolution can extend the timeline, which we scope and agree upon upfront.
