marginfi

marginfi.com

marginfi is a decentralized portfolio margining protocol for trading on Solana. The protocol gives traders a unified account to access margin, compose a portfolio, and improve capital efficiency across underlying trading protocols.

Overview

This crate provides a CPI interface to the marginfi program. It leverages the anchor-gen tool to generate it from the program IDL.

Usage

```rs use anchor_lang::prelude::*;

declare_id!("Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS");

[program]

pub mod example_cpi {

use super::*;

/// -----------------------------------------------------------------------
/// INITIALIZE
/// -----------------------------------------------------------------------

#[derive(Accounts)]
pub struct InitializeAccount<'info> {
    /// CHECK: no validation, for educational purpose only
    pub marginfi_program: AccountInfo<'info>,

    /// CHECK: no validation, for educational purpose only
    pub marginfi_group: AccountInfo<'info>,

    /// CHECK: no validation, for educational purpose only
    #[account(zero)]
    pub marginfi_account: AccountInfo<'info>,

    #[account(mut)]
    signer: Signer<'info>,

    pub system_program: Program<'info, System>,
}

pub fn initialize_account(ctx: Context<InitializeAccount>) -> Result<()> {
    let ctx = CpiContext::new(
        ctx.accounts.marginfi_program.to_account_info(),
        marginfi_cpi::cpi::accounts::InitMarginfiAccount {
            authority: ctx.accounts.signer.to_account_info(),
            marginfi_account: ctx.accounts.marginfi_account.to_account_info(),
            marginfi_group: ctx.accounts.marginfi_group.to_account_info(),
            system_program: ctx.accounts.system_program.to_account_info(),
        },
    );
    marginfi_cpi::cpi::init_marginfi_account(ctx)?;
    Ok(())
}

} ```
