## Description

Complete deBridge Protocol SDK for building cross-chain bridges, message passing, and token transfers on Solana. Use when building cross-chain applications, bridging assets between Solana and EVM chains, or implementing trustless external calls.

# deBridge Solana SDK Development Guide

A comprehensive guide for building Solana programs with the deBridge Solana SDK - enabling decentralized cross-chain transfers of arbitrary messages and value between blockchains.

## Overview

deBridge is a cross-chain infrastructure protocol enabling:
- **Cross-Chain Transfers**: Bridge assets between Solana and 20+ EVM chains
- **Message Passing**: Send arbitrary messages across blockchains
- **External Calls**: Execute smart contract calls on destination chains
- **Sub-Second Settlement**: ~2 second median settlement time
- **Capital Efficiency**: Intent-based architecture with 4bps lowest spreads

### Key Features
- 26+ security audits (Halborn, Zokyo, Ackee Blockchain)
- $200K bug bounty on Immunefi
- 100% uptime since launch
- Zero security incidents

## Quick Start

### Installation

Add the SDK to your Anchor/Solana program:

```bash
cargo add --git ssh://git@github.com/debridge-finance/debridge-solana-sdk.git debridge-solana-sdk
```

Or add to `Cargo.toml`:

```toml
[dependencies]
debridge-solana-sdk = { git = "ssh://git@github.com/debridge-finance/debridge-solana-sdk.git" }
```

### Basic Setup (Anchor)

```rust
use anchor_lang::prelude::*;
use debridge_solana_sdk::prelude::*;

declare_id!("YourProgramId11111111111111111111111111111");

#[program]
pub mod my_bridge_program {
    use super::*;

    pub fn send_cross_chain(
        ctx: Context<SendCrossChain>,
        target_chain_id: [u8; 32],
        receiver: Vec<u8>,
        amount: u64,
    ) -> Result<()> {
        // Invoke deBridge send
        debridge_sending::invoke_debridge_send(
            debridge_sending::SendIx {
                target_chain_id,
                receiver,
                is_use_asset_fee: false,  // Use native SOL for fees
                amount,
                submission_params: None,
                referral_code: None,
            },
            ctx.remaining_accounts,
        )?;

        Ok(())
    }
}
