# Integrating with zkVMs zkVMs produce ZKPs of the validity of arbitrary computations. Very often, these proofs are STARK proofs, which are expensive to verify in Ethereum smart contracts. Consequently, these STARK proofs can be recursively wrapped to generate a Groth16 or PLONK proof which can be efficiently verified on-chain (in the EVM or similar execution environment). In this section, we describe how to take such Groth16 proofs and aggregate them via UPA. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.nebra.one/integrating-with-zkvms.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
