    <strong>Performance-first Rust Framework to build APIs compatible with the Solana Actions Spec.</strong>
  </p>

Znap is an innovative Rust-based framework designed to simplify the creation of [Solana Actions](#) on the Solana blockchain.

- Rust eDSL for writing Solana actions
- Macro collection
- CLI and workspace management for developing complete Solana actions

If you're familiar with developing using the Anchor framework, then the experience will be familiar.

## Getting Started

1. `cargo install znap-cli`
2. `znap init <my-project-name>`
3. `cd <my-project-name>`
4. `znap new <collection-name>`

        let account_pubkey = Pubkey::from_str(&ctx.payload.account)
            .or_else(|_| Err(Error::from(ActionError::InvalidAccountPublicKey)))?;
        let receiver_pubkey = Pubkey::from_str(&ctx.params.receiver_address)
            .or_else(|_| Err(Error::from(ActionError::InvalidReceiverPublicKey)))?;
        let transfer_instruction = transfer(

        let transaction_message = Message::new(&[transfer_instruction], None);
        let transaction = Transaction::new_unsigned(transaction_message);

Ok(ActionTransaction {
            transaction,
            message: Some("send donation to alice".to_string()),
        })
    }
