If I had a nickel for every time someone named Frank in the solana ecosystem turned out to be a snake oil salesman, I'd have two nickels. Which isn't a lot, but it's weird that it happened twice

Prepare to hold your color
Please make sure your bSOL is either in your wallet or in a supported DeFi protocol.
All DeFi integrations have been added to the snapshot script. It was a difficult process, but no bSOL holder will be left behind!
Continuing to do further testing before taking the snapshot 🫡

i wanna talk more about slumlord's design. i think its the most deliciously simple onchain program we've ever designed and it fully makes use of some less well-known properties of the SVM runtime to achieve its goals 🧵👇

We've built upon the model pioneered by

We are putting out some early stage test utils that allow you to easily create test token accounts and provide traits for method call chaining on ProgramTest and BanksClient among other things:
if you're starting out in anchor, don't waste your time writing typescript tests.
use solana-program-test. it's much, much better and faster.

Yes. Yes. Yes. Most of the time you really only need pubkey and the basic crypto stuff like signing and pda computation. No borsh and no usage of libraries below 1.0. Im sick of compiling all this zk crap when i dont even use any of it

@HeyAndyS
Hashmaps are usually not needed because the solana runtime itself is a giant hashmap; Whats your hashmap key? Account pubkey? Simply use PDA[account pubkey] (maybe adding a fixed prefix/suffix to prevent collisions with other PDAs) and store the value at that address
