Description
## SolPayTool — Solana Payment Platform for Sale **Asking Price: $1,999 — Negotiable** SolPayTool is a developed, pre-revenue Web3 payment platform designed to simplify SOL payments for merchants, freelancers and digital businesses. The project combines a React/TypeScript web application with a custom Rust-based payment program deployed on Solana Mainnet. The platform was developed and previously tested with successful payment transactions. It is now available for acquisition by a developer, entrepreneur or Web3 company interested in further development and commercialisation. ### Key Features - **Solana Payment Links:** Generate and share payment links with a recipient wallet address, amount and optional description. - **Non-Custodial Payments:** SOL is transferred directly from the payer's wallet to the designated recipient. - **Phantom Wallet Integration:** Connect a compatible Phantom wallet to authorise payments. - **On-Chain Fee Processing:** The custom Solana program distributes the merchant payment and transaction fee. - **Flexible Fee Structure:** Currently configured for a 0.75% transaction fee with a minimum of 0.005 SOL. These are illustrative settings that can be modified through source-code changes and a corresponding program upgrade. - **Transaction Confirmation:** Includes Solscan transaction links. - **Custom Rust Smart Contract:** Deployed on Solana Mainnet with upgrade authority available for transfer. ### Technology - React, TypeScript and Vite - Solana Web3.js - Phantom Wallet Adapter - Rust / Solana Program - GitHub source repository - Vercel deployment ### Assets Included in the Sale - solpaytool.com domain - Existing SolPayTool website and payment application - Frontend source code - Rust smart contract source code - Deployed Solana Mainnet program - GitHub repository and development history - Relevant project documentation and existing development files - Secure transfer of program upgrade authority ### Development and Verification The project has been compiled successfully, and its local program binary was confirmed to match the deployed Solana Mainnet binary using SHA-256 comparison. The upgrade authority key has also been verified against the authority recorded on Mainnet. ### Current Status and Disclosures SolPayTool is a pre-revenue project with no established commercial customer base. The payment flow was previously tested successfully, but current production functionality has not been independently retested. The smart contract has not undergone an independent security audit. A known issue involving validation of the fee recipient requires remediation before commercial deployment. The project is sold **as-is**, with no commitment to ongoing development, maintenance or technical support. ### Potential Applications The existing codebase could serve as a starting point for a Solana payment service, merchant checkout solution, Web3 payment integration or other blockchain-based payment product. ### Reason for Selling The owner is concentrating on other business activities and no longer has the time to continue developing the platform. **Asking Price: $1,999 USD — Reasonable Offers Considered.** Website: https://solpaytool.com Serious enquiries welcome.
Tech stack
Growth opportunities
SolPayTool offers several opportunities for further development and commercialisation within the Solana ecosystem. Potential areas for growth include: - **Merchant Adoption:** Target freelancers, digital businesses and online merchants looking to accept SOL payments. - **E-commerce Integrations:** Develop payment plugins for Shopify, WooCommerce and other online commerce platforms. - **Token Support:** Extend the existing SOL payment system to support SPL tokens and compatible stablecoins. - **Flexible Monetisation:** Adjust transaction fees and minimum charges to suit different business models. - **Developer API:** Introduce API access, webhooks and payment verification tools. - **Merchant Dashboard:** Add transaction history, reporting and payment management features. - **International Expansion:** Market the platform to businesses interested in non-custodial blockchain payments.

How the escrow transaction works
- 1. Payment to escrow
You pay for the listing — funds go to an escrow account, not directly to the seller.
- 2. escrow_held — funds secured
Funds are locked. The seller transfers the domain, code and access.
- 3. in_inspection — inspection period (7 days)
Check the assets you received and confirm receipt to release the funds.
- 4. completed — funds released
Transaction complete. The business is now yours.
Funds are released to the seller only after you confirm receipt of the assets.
