Frequently Asked Questions
Get clear answers on timelines, security, and process for your cross-chain smart contract project.
A Multi-Ecosystem Simplified Payment Verification (SPV) contract is a lightweight, verifiable proof system that allows a smart contract on one blockchain (e.g., Ethereum) to trustlessly verify events or state from another blockchain (e.g., Solana, Polygon). You need one to build secure, scalable cross-chain applications like asset bridges, oracle networks, or interoperable DeFi protocols without relying on centralized intermediaries.
