Frequently asked questions

Everything about custody, chains, setup, integrations, and licensing for My Crypto Server, the self-hosted, non-custodial crypto payment gateway you own.

Custody & security

Is this custodial? Do you ever hold my funds?

No. Funds are sent directly to addresses derived from your own mnemonic. We never see your seed, and the app itself only derives; it does not sign or move money. You can verify on-chain that every payment address belongs to your wallet.

How are webhooks kept secure?

Every webhook is signed with HMAC-SHA256 and carries a timestamp with replay protection. Your backend verifies the signature over the raw body before trusting the event, and delivery is idempotent so retries can't double-fulfil an order.

What happens if I lose my seed phrase?

The same as with any self-custody wallet: only you hold the seed, so only you can recover the funds. Back it up securely. My Crypto Server never has it and cannot recover it for you.

Chains & assets

What chains are supported?

Fourteen mainnets are live today: Bitcoin, Ethereum, Base, Arbitrum One, Optimism, Polygon, Linea, Mantle, BNB Chain, Avalanche, Solana, Tron, Litecoin, and Dogecoin. Each is integrated properly (native address derivation, reorg-aware confirmations, per-chain detection), not bolted on. More chains are on the roadmap and ship free within the v1 line.

Can I accept stablecoins like USDC and USDT?

Yes, today. USDC and USDT are supported on every chain that has them, and DAI on the EVM chains. Stablecoin amounts settle 1:1 against the order's USD price, so a $100 order is $100.

Which network is cheapest for customers paying USDT?

Tron (TRC20) is usually the cheapest and fastest for USDT, which is why so much stablecoin volume runs on it. The customer chooses their network at checkout.

Setup & infrastructure

What infrastructure do I need to run this?

A Vercel project for the Next.js app, any Postgres database (Neon, Supabase, RDS, or self-hosted), and an Alchemy API key (Alchemy Notify webhooks resolve payments, so there's no separate watcher process). Free tiers cover most small stores, and a full deployment guide is included.

How long does it take to go live?

About an hour. Deploy to Vercel, attach Postgres, add your Alchemy key, and point it at your wallet. There's no application, approval, or underwriting to wait on.

Do I need to run a blockchain node?

No. Payment detection runs through Alchemy Notify, so there's no node or long-running watcher process to operate.

Integrations

How do I connect it to my store or app?

A WooCommerce plugin ships with the source. For Shopify, custom carts, or headless apps, use the REST API and TypeScript SDK to create charges, plus signed webhooks to mark orders paid.

Can I run it alongside Stripe or PayPal?

Yes. Most stores add crypto as an extra option. Card customers keep paying with cards; crypto customers pay you with 0% platform fees. You keep both funnels.

Can I build my own checkout UI?

Yes. Use the hosted checkout for zero UI work, or drive the API directly and render your own payment screen.

Licensing & updates

Can I resell this to my clients?

No. The license is for your own use: self-host on unlimited servers for your own stores and projects, but you may not resell, redistribute, or sublicense the source, deploy it on behalf of clients, or offer it as a SaaS. Each business that runs it needs its own license.

Why one-time instead of a subscription?

Because you self-host it. You own the source and run it on your own boxes; billing you monthly for software on your own servers makes no sense. One purchase covers the entire v1 line: every 1.x release, free. A future major v2 rebuild would be a separate, optional purchase.

What updates are included?

Every release in the v1 line (1.0, 1.1, 1.2, all the way through the end of v1): bug fixes, new chains, new features. There's no remote kill switch, so your v1 install keeps working indefinitely even if you never upgrade.

Support & refunds

What if I find a bug or need a feature?

Email support during setup is included, and you can open issues on the private GitHub mirror. Bug fixes ship to all license holders. Feature requests get triaged and built when broadly useful.

Is there a refund policy?

Yes: 14 days, as long as you haven't pulled the source yet. The moment you clone or download from the private repository, the source is on your machine and the sale is final. Try the live demo and read the docs before you pull.
