While fully compatible with EVM, the SVM has been architected to follow the leading universal VM found in computers worldwide, the x86–64 OS process model, with possible extensions to arm64 in the future. The SVM enables on-chain security parameters to allow smart contracts to interact differently with each other in accordance with their risk tolerance. Additionally, the SVM is designed to support a smart contract sandbox, isolating the operation of smart contracts (especially those that have yet to be secured) from the rest of the system.
