can an auditor build a defi protocol? I'm pretty certain I can write a smart contract with zero security related bugs 👀 possible? or overconfident?

When transferring all SOL out of an account on Solana (aka "closing" the account), the account doesn't actually get removed until the end of the transaction. Done naively, this allows attackers to reuse or reinitialize the account, potentially draining funds from the protocol 🫢

Solana's official "Token Program", released in 2020, serves as an "ERC-20"-like program for creating fungible and non-fungible tokens. Interestingly, a new "Token-2022 Program" was developed, stemming from an issue with Solana's programming model.

Solana programs do not have overflow/underflow checks on by default. You must enable them by setting `overflow-checks = true` in your Cargo.toml

Hey @v sorry for the ping but my friend's casts are not showing up in any channels. Did he get shadowbanned or something?

I can't seem to find this cast that was posted /founders recently. Bug? https://warpcast.com/harsh/0x190e3716

Solana uses a fixed size stack frame of 4KB. This means if a function call uses more than 4KB of parameters, local vars, etc. then the program (thankfully) crashes

One way to bridge assets (or send messages in general) to/from Solana is to use the Wormhole protocol. Wormhole has an off-chain network of "Guardians" that pass these messages across chains. However, there are exactly 19, and only 19... anyone know something about this? https://wormhole.com/blockchains/#guardians

Lido's stETH is a rebasing token. Rebasing tokens are problematic to integrate with for the majority of protocols, due to holder balances constantly shifting. Fortunately Lido recognizes this and offers wstETH, representing *shares* instead, which are stable across rebases, making it compatible with defi in general.

On Solana, you can have a single transaction that makes multiple top-level program calls. In contrast, an EVM tx only supports sending calldata to a single contract address.

Security question: If deploying a contract can take 100-1000x transactions, then how does upgrading a contract work for that same number of transactions? Will the contract still function? As its old version? Or do you upload to a buffer and switch to it in 1 tx instead?

EVM smart contracts don't really have a max size, since an SSTORE opcode has an entire 256 bits of address space to write to (in theory, anyway) Solana accounts have a max size of 10 MiB, which must be incremented to via the limit of 10 KiB per instruction.
