Why We Built JamsrPay

Traditional payment rails were architected decades ago around legacy bank networks. For online businesses, this means losing 3% to 5% on every transaction, suffering chargeback fraud, and waiting days for payouts.

JamsrPay replaces the legacy middleman with decentralized on-chain settlement. We provide modern APIs, hosted checkouts, and official SDKs so any business can accept crypto directly into their wallet with zero counterparty risk.

Transparent, volume-tiered rates starting at 0.4% down to 0.25%
