Does EIP-152 work on Ethereum L2s like Arbitrum?

Yes, ZAP1Verifier's deployed there — same gas savings, assuming the L2 inherits the precompile.

How much gas for full Zcash Sapling proof verification?

Around 22,800 for hashing alone; total under 50K with Merkle ops. Feasible in one tx.

It's niche — Zcash-specific. Most devs chase NFTs or memecoins, not privacy proofs.

A dusty precompile from 2019 just made Zcash light-client verification feasible on Ethereum — at 22,800 gas per proof. Who's been sleeping on this?
