Контракт с одним адресом на все EVM-блокчейны: как работает Safe Singleton Factory
Когда мне понадобилось задеплоить один и тот же контракт в разные EVM-сети с одинаковым адресом — оказалось, что всё не так просто. Даже если всё заранее посчитать и подготовить, любой лишний nonce может всё сломать. В этой статье я разбираю, как вообще формируется адрес контракта при деплое (при использовании CREATE и CREATE2), зачем появился Deterministic Deployment Proxy, и почему Safe в итоге сделали свою версию — Safe Singleton Factory. Расскажу, как ей воспользоваться через Remix, Foundry и Hardhat, на что стоит обратить внимание (например, при работе с байткодом), и какие грабли могут ждать при попытке всё упростить.

I'm finally moving over to Radicle (https://radicle.xyz) instead of switching to another centralized code forge (like GitHub, GitLab, Codeberg, etc.). I definitely love the idea behind a #P2P code forge and I'm hopeful for Radicle's future, but I do have some reservations starting off:
1) Despite talking a lot about freedom and privacy in the tutorial, the group building Radicle (https://radworks.org/) is planning to sell hosting and make a profit via an Ethereum-based cryptocurrency (https://www.tally.xyz/gov/radworks) as well as NFTs and smart contracts. Some big Libertarian red flags there.
2) At some point there was a Swiss nonprofit "Radicle Foundation", but this now seems to be a for-profit venture (see https://radicle.xyz/history). I wish it could just be a nonprofit.
3) In the user guide chapter on private repos (https://radicle.xyz/guides/user), it says that I need to use a public DNS address trusted seed node to share the repo. I understand there's no DHT here, but I hope it's not too much of a pain to run this over my local network instead of the internet. (And yeah, I know I can use git locally, I just want to test Radicle locally.)
Overall, I think that if radworks turns out to be evil it will be a way easier transition to fork Radicle than it has been to leave GitHub, but I still wish I didn't have to worry.
middle managers being replaced by DAO (decentralized autonomous organizations) is a very real near future possibility https://builtin.com/blockchain/decentralized-autonomous-organization
