Short answer: The answer is that there's no difference. In this case, #[account] has no effect in the generated code. The reason for this is that the parsing logic for the #[account] macro in this spe …

Looks like the User struct isn't serialized with Borsh on the drift side, hence deserialization that way will fail. It's a zero-copy account instead. Try using anchor's AccountLoader to deserialize ac …

Clockwork lets you do this. It's an automation engine that lets you schedule transactions. Check out this repo for an example of on-chain usage. Here a Pda is given delegation over a token account, ma …

Both pack and unpack are provided by the Pack trait. You'll have to first bring the trait into scope with use solana_program::program_pack::Pack;

You can only conveniently access code written in Anchor with the interface Anchor provides through its ts package. This is because the entrypoint to an Anchor program first attempts to strip any instr …

Try this: impl<'info> BuyIn<'info> { pub fn transfer_to_vault(&self, amount: u64) -> Result<()> { let cpi_context = CpiContext::new( ctx.accounts.system_program.to_account_info …

A way to do this would be to create a separate account for each wallet that contributes. That account would be a PDA to prevent duplicity, and would store contribution details such as the amount contr …

Here's a code snippet to transfer tokens from a token account with PDA authority: let config_bump = ctx.accounts.config.bump; let config_seeds = &[ "config".as_bytes().as_ref(), ctx.accounts. …

Quoting an answer to this exact issue as shown here, with minor changes: "0x0 means you're attempting to initialize an already initialized account. What's happening here is that because your vaultAcco …
