With EIP-4488 now coming post-Merge, here are other avenues to lower fees on rollups:

- Optimizations & calldata compression: Arbitrum Nitro will halve fees, Optimism working on it
- Wallets supporting BLS signatures: Arbitrum can enable it: easy ~1K gas reduction

(1/7)

- Socially & financially incentivize developers to deploy on rollups. Particularly memecoins & NFTs, which have been the majority culprit for excessive gas fees on Ethereum
- Incentives for dapps on rollups - Uniswap liquidity mining coming to A1 & OE is a big deal

(2/7)

- Greater usage on rollups -> lower fees. Currently, a swap on zkSync / ZigZag costs $0.61, will go lower. (Source: L2fees)
- Volitions: StarkNet & zkSync will both have alt-DA options. zkPorter estimates $0.01-$0.03 tx fees. Lower security, but still higher than alt-L1s.

(3/7)

- Explore minimum viable consensus layer solutions post-Merge as an alternative to 4488: e.g. dataspace on Beacon Chain, have just 1 data shard sharing p2p layer with Beacon Chain, or 4 data shards, 1 subnet, everyone validates etc. Just thinking out loud here.

(4/7)

(Btw: NEAR's first phase is like that: 4 "shards" but everyone validates)

- Rollup teams implement better security. More transparent and broader community multi-sigs, and ideally, with timelocks. Doesn't lower fees, but will make people more comfortable using rollups.

(5/7)

- More efficient L1 fee determination by rollups. Today, Optimism has a 1.5x buffer which is totally excessive. If you have a moving average function, we can easily drop this down to ~1.0x. Evade spikes by delaying batch submissions. Also, consider loss-leading.

(6/7)

I expect gas prices to be ~20 gwei if speculative activity like memecoins & NFTs see a lull. Swaps on ORs could be <$1, and <$0.25 on ZKRs. I think we accomplish a lot with social consensus. Let's use this time to push developers & people to using rollups by default.

(7/7)

Potential action plan:

- Tell all your friends & followers to use rollups, skip Ethereum
- Tell developers to deploy on rollups. If memecoin or NFTs, consider skipping Ethereum entirely.
- Push MetaMask & wallet teams to support BLS signatures
- Push CEXs to integrate rollups
