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:

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

Or add to Cargo.toml:

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

Basic Setup (Anchor)

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(())
    }
}
