Code Sample

use anchor_lang::prelude::*;
use anchor_spl::token::{Mint, Token};

// Stablecoin Protocol (Solana / Anchor)
#[program]
pub mod stablecoin {
    use super::*;

    pub fn open_vault(
        ctx: Context,
        collateral_amount: u64,
        mint_amount: u64,
    ) -> Result<()> {
        let price = ctx.accounts
            .oracle.get_result()?.try_into()?;
        let ratio = collateral_amount
            .checked_mul(price).unwrap()
            / mint_amount;

        require!(
            ratio >= ctx.accounts
                .config.collateral_ratio,
            StableError::BelowRatio
        );

        // Transfer SOL & mint stablecoins
        anchor_lang::system_program::transfer(
            ctx.accounts.deposit_ctx(),
            collateral_amount,
        )?;
        token::mint_to(
            ctx.accounts.mint_ctx(),
            mint_amount,
        )?;
        Ok(())
