NEBRA's Universal Proof Aggregator (UPA) is our answer to the growing cost of on-chain ZK proof verification.
UPA aggregates proofs into batches, passing on the savings to you. The current release of UPA targets the popular proof system Groth16. Aggregating your proofs with UPA can save you up to 90% in verification costs!
We have used UPA to aggregate 1 million proofs in 36 hours. Check out the contract here.
