Solana Smartcontract

Hello! Ready to undertake the development of a decentralized payment system on Solana. The project is not simple, but it matches my profile — it can be implemented from scratch, focusing on stability, scalability, and proper architecture.

In the first stage, we will build a system that accepts payments in SOL, USDC, USDT, and any other SPL tokens. I will create a smart contract on Anchor, where each transaction will go through a separate address, with validation of amount, status, and token. All of this will be linked to a website, with API, payment status updates, and the ability to send notifications.

Integration with the frontend is no problem. Support for Phantom, Solflare, Trust Wallet, and other popular wallets via Wallet Adapter. We will immediately show the user: “Awaiting payment,” “Successful,” “Error.” If needed, escrow can be added or partial payments can be planned.

In the second stage, cross-chain support can be added — via Wormhole or LayerZero. This will allow accepting ETH, USDT on ERC20/BEP20, and transferring confirmation to the Solana network. Connecting with TON is a bit more complex but also possible, especially if there is an intermediate server or third-party API.

Timeline — 3–4 weeks for the first part. Price — from $3000, depending on details. Cross-chain will be discussed separately, as much depends on the chosen architecture and logic volume.
…
If everything is okay — send the details: which tokens, how the fee is split, whether escrow is needed, etc. We can connect via Zoom/Telegram, discuss, and start.

Good afternoon, Maxim!

I professionally develop microservices in Python for blockchains.
I am ready to create a decentralized payment system on the Solana blockchain for an online marketplace.
I can adapt the interface to yours.

Write in private, let's discuss the details!

Hello! We have already worked on similar tasks: implemented smart contracts on Solana supporting payments in SOL, USDC, USDT, and other SPL tokens, including integration into custom e-commerce solutions. Currently, we have a ready-made solution base:

– a written and tested smart contract for Solana that accepts payments linked to order metadata (safe escrow implementation if necessary);
– front-end integration with Phantom and Glow Wallet via Solana Web3.js;
– backend on Node.js implementing webhooks to track successful transactions and interact with the order database;
– modular architecture allowing scaling for NFT, marketplaces, landing pages, or hybrid applications.

We also implemented internal token verification via whitelist/blacklist, logic for handling multi-currency receipts, and an advanced logging system. Cross-chain support (ETH, BSC, TON) can be added at the second stage through LayerZero or Router Protocol — we have previously done similar integrations.

… For UI/UX, we can offer a solution similar to Cryptoinemporium, as shown in the example, with branding adaptation. The MVP timeline is from 7 to 10 working days. We are ready to connect now — we will explain the entire architecture and provide documentation.

Hello, Stepan

I can do turnkey on any networks within reasonable timeframes.
As I understand, the goal is to create a widget + payment gateway + cross-chain aggregator under the hood.

Waiting for your message.
