Discussions about the Ethereum Virtual Machine
we live in the early blockchain era when people mostly issue fixed supply tokens to satisfy markets that find dynamic supply token software difficult to digest
Anyone have strong feels for where to draw the line for a contract that *is* a proxy vs one that happens to contain a proxy-like thing? Specifically for WhatsABI's proxy autoresolving.
My current ideas is if the contract has an SSTORE then treat it as a destination contract first, proxy second? Is there a better heuristic?

Optimism has a pretty monstrous solidity codebase at this point, including a ton of tests and scripts.
Build times were starting to get pretty horrendous. Something we did that significantly improved the speed is to use this pattern of using `vm.getDeployedCode()` and `vm.etch()`.
This compiles MUCH faster than the `new SomeContract()` syntax, because the script/test doesn't need to wait for the contract being deployed to compile first.

Foundry protip: if your traces are hard to read because of huge vertical blocks of bytecode and other gunk, use `tput rmam` to disable wrapping. (`tput smam` to revert).

I want to make a simple mint frame that accepts erc20 payments for mints. Aiming for one click.
IMO the approval step adds confusion for first timers.
Is there an elegant way to transfer an erc20 to a contract and then check that msg.sender has sent the appropriate amount before minting?
All roads I've thought through so far lead to the check offchain. I'm ok with that but wondering if someone has done something similar and can help me out!

What's the magnitude of negative externality from @dune.eth buying the sim.io team and killing evm.storage? Auditors relied on it, now there's no substitute.
Maybe the next billion dollars North Korea steals will be because of this?
At least evm.codes was OSS from the same team so it's still around.

1) My latest PG extension decodes arbitrarily complex ABI data
2) Crypto companies should accept crypto payments

@daimo is the simplest service for accepting any coin, on any chain, from any wallet. Index Supply is the simplest API for instant access to Ethereum. But can they blend?

The growth stagnated because of L2 fragmentation
Decentralization is good for infrastructure…

Ethereum needs @VitalikButerin and Foundation to take back control and grow its ecosystem!

Honestly we should stop using terms like "transactions", "user operations" or "messages" when talking about Wallets
Just call it "actions"... for every Wallet approval 😎

does anybody know how to get Tenderly to recognize minimal proxy clones/instances of an already-verified implementation contract?
I found Convert to Proxy, but I need the inverse; more like "Convert to Implementation"

Introducing Create3s: Cheaper Create3 deployments for small sized contracts.
Create3s is up to 35K gas cheaper than Create3 for contracts sized <= ~3.6KB. The smaller the bytecode, the more gas saved.
For how this works, here is the link to the repository.

Ethereum should follow the steps of Optimism ❤️
Spin out the L1 execution into an L2 and rename it to “ETH Mainnet” with new logo
Then educate the world about Ethereum ecosystem
Ethereum is not ETH Mainnet
Ethereum are all the L2 rollups with ETH as gas

We can do better than having separate fee markets per "state hot spot": We can have fee markets per temporal event relating to a hot spot!
Imagine an ephemeral rollup that automatically deploys to aggregate state for a hot spot, then collapses state back into the L1 once the hot spot dissipates.
Could we make this completely transparent from the user's perspective and fully inherit security using native rollups?
We could have some settings on a per-contract level to enable this, the contract could choose a sequencer strategy if it needs to aggregate (contracts could commission their own sequencers for additional business models during periods of high activity).
Space ➡ Time.
