debridge-solana-sdk

About

debridge-solana-sdk allows you to easily and quickly connect your Solana programs to the debridge infrastructure. Debridge protocol enables decentralized transfers of arbitrary messages and value between various blockchains. See Debridge documentation for more information docs.

Project Structure

• At the root of the git repository you will find auxiliary methods to integrate debridge
• In example-program folder you will find an example program with different usage cases

Create a simple message and value transferring to other chain

This example show how you can send some tokens and message to any supported chain using debridge-solana-sdk crate.

Create a new program with Anchor

Debridge-solana-sdk doesn't depend on any solana framework like Anchor and can be connected to any Solana program. But for simplifying example we will use example program built with Anchor.

anchor init send-via-debridge

Add debridge-solana-sdk crate

Next step is add debridge-solana-sdk crate to program dependency:

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

Create simple contract with using Debridge protocol

Add in ./send-via-debridge/programs/src/lib.rs code of simple smart contract that transfer tokens and message to other chain with debridge solana program:

use anchor_lang::prelude::*;

declare_id!("3botMWU4s1Lcs4Q2wQBkZqsCW1vc3N9H9tY9SZYVs5vZ");

#[program]
pub mod send_via_debridge {
    use debridge_solana_sdk::prelude::*;

    use super::*;

    pub fn send_via_debridge(ctx: Context<SendViaDebridge>) -> Result<()> {
        invoke_debridge_send(
            SendIx {
                target_chain_id: chain_ids::POLYGON_CHAIN_ID,
                receiver: hex::decode("bd1e72155Ce24E57D0A026e0F7420D6559A7e651").unwrap(),
                is_use_asset_fee: false,
                amount: 1000,
                submission_params: None,
                referral_code: None,
            },
            ctx.remaining_accounts,
        )
        .map_err(|err| err.into())
    }
}

#[derive(Accounts)]
pub struct SendViaDebridge {}

Build and deploy example contract

Build program with anchor:

cd example_program; anchor build

Deploy program

solana program deploy --program-id target/deploy/send_via_debridge-keypair.json ./target/deploy/send_via_debridge.so

Write and run tests

Add file ./send-via-debridge/tests/send-via-debridge.ts with next test case:

import * as anchor from "@project-serum/anchor";
import { Program } from "@project-serum/anchor";
import { SendViaDebridge } from "../target/types/send_via_debridge";
import { AccountMeta, PublicKey, Signer } from "@solana/web3.js";

function accountsToMeta() {
  const result: AccountMeta[] = [

  return result;
}

describe("send-via-debridge", async () => {
  anchor.setProvider(anchor.AnchorProvider.env());

  const program = anchor.workspace.SendViaDebridge as Program<SendViaDebridge>;

  it("Send via Debridge!", async () => {
    const builder = await program.methods
      .sendViaDebridge()
      .signers([program.provider.wallet.payer]);
    builder.remainingAccounts([...accountsToMeta()]);

    let tx = await builder.rpc();

    console.log("Your transaction signature", tx);
  });
});

Then in ./send-via-debridge/Anchor.toml change cluster to mainnet to use Debridge production contract:

[provider]
cluster = "mainnet"

To run test use with build and deploy contract use:

anchor test

To test running only use:

anchor test --skip-build --skip-deploy
