Which cryptocurrencies does JamsrPay support?

JamsrPay supports all major cryptocurrencies including USDT (TRON, BNB Chain, Ethereum, Solana, Polygon), USDC, Bitcoin (BTC), Ethereum (ETH), Solana (SOL), TRON (TRX), BNB, Litecoin, and more.

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 29-day free trial, 0% chargebacks, and zero monthly subscription fees. Volume rates scale down automatically to 0.25%.
