I saw some good websites charging more than actual gas cost for batch register/renewals. So I made my own contract… max opinionated/optimized with builtin chainlink ETH_USD price feed to calc exact pricing, fully packed calldata with dnswire, offchain utf-8 char counters… all written in 100% assembly as fun experiment. Also supports max calldata compression using Solady/libzip as fallback mechanism.
Minimum fee per batch : ZERO
Fixed max fee per batch : 0.00015 ETH
Downsides: no premium domain support, GIGO contract design is making hard to estimate gas, so it’s hardcoded.
v0 Etherscan verified contract

*might do proper v1 contracts for future…
