DePay

The widget provides an embeddable payment interface that lets merchants receive cryptocurrency directly into their own wallets. It supports peer‑to‑peer transfers on multiple blockchains—including Ethereum, BNB Smart Chain, Polygon, Solana, Optimism, Arbitrum, Avalanche, Gnosis, Base and Worldchain—and works with a wide range of wallets and tokens such as stablecoins. Payments are initiated from the customer’s wallet and settle instantly without intermediaries, and the widget can be configured either through a managed integration ID that fetches settings from DePay’s service or via an unmanaged payload that specifies blockchain, amount, token and receiver directly in code.

Developers integrate the solution by adding a small JavaScript bundle via CDN or by installing the npm package @depay/widgets (or platform‑specific packages for EVM or SVM). The library requires standard dependencies like ethers, react and react‑dom, and can be used in client‑side code or, with care, in server‑side‑rendered frameworks such as Next.js. Configuration options allow single‑ or multi‑blockchain payments, and optional payloads enable dynamic backend logic.

The project is released under the MIT license, is self‑hostable, free to use, and does not require a subscription. It is positioned as an open‑source, stable‑maturity tool for anyone needing to accept Web3 payments directly into their wallet, from small merchants to larger Web3 applications.
