Solana

for people looking to build solana mini-apps on farcaster fast, some tips below 👇:

1.	you don’t need to write smart contracts for 90% of use cases.
most protocols already expose great typescript and rust sdks.

👉 https://github.com/sendaifun/solana-agent-kit has everything to get you started.

2. landing a transaction on solana is tricky.

use this guide to properly set priority fees: https://www.helius.dev/blog/how-to-land-transactions-on-solana
or use jito bundles for transaction atomicity.

3.	everything is an account, and every account has an owner.

half of the bugs happen because you’re accessing the wrong account. understand the account model well:

4.	evm → svm mental model:

abi        = idl  
eoa        = account (owned by system program — the godfather)  
contracts  = programs aka program accounts (owned by bpf loader)

5.	once you understand pdas, they become an incredibly powerful tool.
this guide helps you shift from evm to svm thinking

6.	if you’re using partial signing:

make sure the frontend (farcaster wallet) signs the transaction before the backend does.
⚠️ not recommended as-is — the frontend can send a malicious transaction. if you do this, use it with a nonce.
the current farcaster wallet setup invalidates previous signatures — the team is working on fixing this.

7.	use good rpcs: helius, triton, or quicknode are reliable choices.

once you understand the solana account model and how transactions are formed, it all gets much simpler.

the solana community is actually super welcoming — way more beginner-friendly and supportive than people often perceive.

too late. i already deployed the rust contract and am trying to figure out how to create a frontend around it

I really appreciate your post, thearyanaq. very usùeul, this is what i need

This is great. Thanks for laying it out so clearly.

appreciate this very much, was looking into how to build mini apps yesterday, making it my weekend project 🫡

Nice work, landing transactions on Solana is very tricky

can you write more about the farcaster part, for pops that already know about solana ? 🙂

pls 😆🙏
