How do I integrate JamsrPay into my application?

You can integrate using our REST APIs, SDKs (TypeScript, Python, Go, Rust, PHP), and pre-built hosted checkout. A developer staging sandbox is available with instant test API keys.

Do you custody customer or merchant funds?

No. JamsrPay is non-custodial. We never hold your private keys or touch your balance sheet. Payments route directly from customer wallets to your designated merchant wallet address.

How does settlement work?

Once confirmed on-chain, JamsrPay instantly detects the transaction, cryptographically signs and broadcasts a webhook notification, and your funds settle directly to your self-custody wallet in real-time.

What are the processing fees?

Transaction fees start from just 0.4% + $0.25 with a 30-day free trial, 0% chargebacks, and zero monthly subscription fees. Volume rates scale down automatically to 0.25%.
