summary

HEMVM integrates EVM and MoveVM inside an Aptos-based prototype by adding two system APIs and an invoker/handler pattern so contracts call across VMs atomically within one transaction. Evaluation shows less than 4.4% overhead for intra-VM work, up to 9,300 TPS for cross-VM paths, and a parallel prototype speeds mixed workloads by up to 44.8%. Implementation reuses existing toolchains and wallets, supports Pancake/Uniswap interfaces, and preserves language semantics while translating permission and parameter models between VMs.
