I'm an indie developer, and I built ChainVault because crypto payment gateways shouldn't be a black box. If you've ever integrated a third-party deposit service, you know the pain: closed source, opaque fees, vendor lock-in, and your customer funds flowing through infrastructure you can't inspect or control. ChainVault is the open-source alternative — a self-hosted multi-chain deposit & withdrawal gateway you run on your own servers. What you get out of the box Merchant API — generate deposit addresses, process withdrawals, query balances & transactions Multi-chain support — ETH, BNB Chain, TRON, BTC (+ USDT on EVM/TRON) Block scanning — automatic deposit detection & confirmation tracking Webhooks — real-time notifications when deposits confirm Hot wallet sweep — configurable auto-collection to your treasury Admin dashboard — manage merchants, view transactions, configure chain nodes Everything ships with Docker-friendly setup, a Vue 3 admin UI, and full API docs. Who is this for? Exchanges & trading platforms needing deposit rails Payment processors accepting crypto SaaS products adding "pay with crypto" Any team that wants UDUN-like functionality without UDUN-like dependency Why open source? Because merchants deserve to own their payment infrastructure. You control the keys, the data, the RPC nodes, and the upgrade path. No surprise API changes. No begging support to explain why a deposit didn't credit. It's MIT-licensed, actively developed, and I'd love your feedback. ⭐ Star us on GitHub: https://github.com/colebishsj937... 📖 API docs included in the repo — docker compose up and you're running in minutes Happy to answer anything: self-hosting, security, chain support, or how this compares to commercial gateways.
