Solana: How do I take the cut from a transaction in Solana/Token?

How ​​to Deduct a Portion of Your Transaction in Solana: A Guide

Solana, a fast and scalable blockchain platform, allows developers to build a wide range of applications on its network. A popular use case is creating token-based products that leverage the Solana coin (SOL). However, when it comes to monetizing these products, there is one key aspect to address: deducting a portion of transaction fees.

In this article, we will look at how to deduct a portion of your Solana transaction and give you tips on how to fund your project through the platform.

Why is it necessary to deduct a portion of transaction fees?

Transaction fees are a significant source of revenue for the Solana ecosystem. When users send SOL to receive a payment, the transaction fee is deducted from the amount. While this feature may seem convenient, it can actually be detrimental to the project if not handled properly.

How ​​to earn commission on Solana transactions: Step-by-step guide

• Make sure you have a Solana node: To earn commission on transactions, you need to have a Solana node installed and running on your own infrastructure.

• Select a transaction fee model: There are two main billing models: the SOL-based model (where users pay in SOL) and the Solana fee model (where you receive a fixed percentage of the transaction fee).

• Set up SOL-based transactions

  : When users send SOL to your token contract, they essentially pay a fee that is deducted from the SOL amount.

• Use the solana-transactions library: To earn commission on transactions, you can use the solana-transactions library which provides a simple API to interact with Solana nodes and manage transactions.

Here’s an example of how to create a transaction that deducts fees from your SOL amount:

import { TransactionConfig } from '@solana/web3.js';
const configuration: TransactionConfig = {
accounts: [
// The public key of the token contract, used to sign transactions
{ pubkey: '0x...Your token public key...' },
],
data: '0x...Transaction data...',
};
async function removal() {
const tx = await transaction.createSignedTx({
configuration,
accounts: [...],
});
await tx_sign(tx);
}

• Manage transaction fees: You need to decide how much of the transaction fee you want to treat as revenue. This amount can be calculated by subtracting a fixed percentage or based on the user’s SOL balance.

Example use case: Token-based product

Suppose you are building a token-based product that allows users to stake their SOL in exchange for rewards and participate in governance decisions. To get a share of the transaction, you can set up a transaction model where users receive a certain amount of reward (e.g. 10% of the transaction fee) in addition to the SOL paid.

Here is an updated example:

import { TransactionConfig } from '@solana/web3.js';
const configuration: TransactionConfig = {
accounts: [
// The public key of the token contract, used to sign transactions
{ pubkey: '0x...Your token public key...' },
],
data: '0x...Transaction data...',
};
async function removal() {
const tx = await transaction.createSignedTx({
configuration,
accounts: [...],
});
await tx_sign(tx);
}

Project Funding via Solana

To fund your product, you need to create a Solana-based token that allows users to purchase using SOL or other tokens. This can be achieved by creating a new token contract and implementing a token creation and burning mechanism.

Here is an example of creating a Solana-based token:

“`javascript

import { TransactionConfig } from ‘@solana/web3.js’;

const configuration: TransactionConfig = {

accounts: [

// The public key of the token contract, used to sign transactions

{ pubkey: ‘0x…Your token public key…’ },

],

date: ‘0x…
