I'm back, what am I missed?
Thank you for your support 💗 New version of 33bits is coming soon
Another great example of making farcaster onchain 🥳
Also, I've submitted farcaster-solidity to the Retroactive Funding Round 5

Released farcaster-solidity v1.4.0 💜

- A huge shoutout to @allemanfredi.eth for helping!
- Fixed bug with decoding casts with empty `mentions` and non-empty `parent_url`. This was caused by the default behaviour of protobuf3-solidity codegen, also submitted a PR there

What are the best practices and tools to increase security of the mnemonic/seed phrase? For example I can imagine building a deterministic permutation in order to create a trapdoor mnemonic. Same could be done by using non-standard derivation path.
Is there any chance to see a GraphQL endpoint for the replicator's db soon?

Is it just me or the quality of topics on https://ethereum.stackexchange.com/ have reduced dramatically over the years? I wonder what is the reason, remember spending days there in 2016-18
Fellas what do you do with old tennis balls? All the dog owners I know now have balls for the rest of their lives.
Amazing example of using farcaster-solidity. Great job, @limone.eth and @frankk 👏👏👏
1/ I've open-sourced my solution for using a beacon proxy with ERC4337 smart contracts, a problem many devs face.

Thanks to @johnrising and @hazim from @stackup and @konrad for their help and comments on it.

Released farcaster-solidity v1.3.0

https://github.com/pavlovdog/farcaster-solidity

- Added support for frame input text
- Provided example for using with frames API + nextjs
Got an FPV kit for Christmas and finally took my first flight in Abu Dhabi 🇦🇪 (loud!).

For those who are wondering, here's a kit link:

@horsefacts.eth's daily job is building frames and I'm jealous of it 😭
What is your favourite option for fully managed hosting? Last year I preferred using DigitalOcean apps, but after trying Vercel, I am considering migrating the rest of my projects into it. Will see how it works, I hope it's not the case where I surprisingly receive a 10k bill after forgetting to disable debug logs.
Farcaster-solidity 0.1.2 is released 🎉

- Added Frame Actions support, so you can attest to Frames actions onchain

In layman's terms - each Frame click comes with a signature, which proves that the user indeed clicked the button. Now you can verify this click onchain, creating trustless onchain frames!
1/ I've been working on a method to verify Farcaster messages onchain. The GitHub repo is now open-sourced under an MIT license.

If you haven't done it yet, take a look at the account abstraction modules.

https://github.com/rhinestonewtf/awesome-modular-accounts

It provides a way to connect plugins to your account (eg social recovery, kill switch, daily limit, etc). I like it so much!
Found this gem from 2018. Take your time and try to remember what happened through these years.

NO MOM, ETF HAS NOT LAUNCHED YET, STOP ASKING 😠😠😠
What is the recommended way for cross-chain storage access with Base? In particular, I have a smart contract in the Base mainnet and I need to read a public variable/storage slot of the contract in the Optimism mainnet. Bridges/oracles/storage proofs/etc, what do we have?
