Optimizing Solana Multisend with SPL Tokens: A Trustless and Efficient Approach
Solana is a fast and scalable blockchain platform that has gained popularity among developers and users due to its high-performance capabilities. One of the key features of Solana is its ability to perform multisending, where multiple addresses can send tokens without needing to interact with a User’s wallet. In this article, we will explore an efficient way of sending any number of addresses some amount of SPL (Solana Token) tokens using the SOL token pair and a trustless approach.
What is Solana Multisend?
Multisending allows users to send multiple transactions on behalf of another user, eliminating the need for them to interact with the wallet. This feature is particularly useful when you need to transfer tokens between accounts or when you want to automate tasks without exposing your wallet to security risks.
Requirements and Setup
To get started with Solana multisend, you will need:
- A Solana node (e.g., Solflare Node or Solana CLI)
- The SOL token pair (SOL/WETH)
- The SPL-enabled wallet (e.g., MetaMask or Ledger Live)
We’ll be using the solana-client library to perform transactions and interact with the Solana network.
Step 1: Create a New Wallet
First, create a new wallet on your Solana node. You can use the following command to generate a new wallet:
npx solana-cli-gen-key --name "newwallet" --key-path ./key.json
This will generate a new private key and corresponding public address for your wallet.
Step 2: Configure the Wallet
Next, configure your wallet to enable multisend. You can do this by editing the solana-client configuration file:
module.exports = {
// ... other configurations ...
multisender: true,
};
This tells Solana that your wallet is a multisender.
Step 3: Send Tokens using Multisend
Now, let’s send some tokens from one address to another using the solana-client library. Create a new transaction and specify the token pair you want to use:
import { Client } from "solana-web-sdk";
const client = new Client();
const multisenderTokenPair = {
pubKey: 'some-public-key',
pubkey: 'some-pubkey',
};
const txParams = {
account0: {
pubkey: 'addr1',
amount: 100,
},
account1: {
pubkey: 'addr2',
amount: 50,
},
multisenderTokenPair: multisenderTokenPair,
paymentId: 'some-payment-id',
};
client.sendTransaction(txParams)
.then((result) => console.log(result))
.catch((error) => console.error(error));
This will send 100 SOL to addr1 and 50 WETH to addr2, using the SOL/WETH token pair.
Trustless Approach: Using a Relay
To achieve a trustless approach, we’ll use a relay mechanism provided by Solana. A relay is an intermediary that can facilitate transactions without exposing its own wallet or private key.
First, create a new relay:
import { Client } from "solana-web-sdk";
const client = new Client();
const relayTokenPair = {
pubKey: 'some-public-key',
pubkey: 'some-pubkey',
};
const txParams = {
account0: {
pubkey: 'addr1',
amount: 100,
},
account1: {
pubkey: 'addr2',
amount: 50,
},
relayTokenPair: relayTokenPair,
paymentId: 'some-payment-id',
};
client.sendTransaction(txParams)
.then((result) => console.log(result))
.catch((error) => console.error(error));
This will send the same transactions as before, using the SOL/WETH token pair and a relay.
Conclusion
In this article, we’ve demonstrated an efficient way of sending any number of addresses some amount of SPL tokens using Solana multisend without needing to interact with a User’s wallet.
