Ark One is for spending Bitcoin. Ark Merchant is for the businesses that don't want a middleman. Both keep your money in you.
A consumer wallet for spending Bitcoin without thinking about Bitcoin. Pay anyone, receive from anywhere, hold your own keys.
Point-of-sale for businesses that want to be paid in Bitcoin and settle to their own keys — no processor, no chargebacks, no middle.
Tap to send. Scan to receive. The protocol underneath is sophisticated; the surface is not.
You hold the keys. Ark cannot freeze, censor, or revoke your balance. Self-custody, by default.
Your funds settle to Bitcoin. Move on-chain whenever you want. No lock-in, no platform.
Send and receive over Lightning natively. The interface stays the same; the rails handle themselves.
A wallet built around the way people actually pay — instant, private, and always under your own keys.
A point-of-sale for shops, counters and counters of one — a payment terminal you actually own.
We don't list tokens. We don't run a chain. There is one asset and one network, and the wallet is built around its grain.
Self-custody is not a setting. There is no account, no recovery email, no support line that can restore your funds.
Every screen does one thing well. No upsells, no toasts, no dashboards within dashboards. Just the next move.
Ark One is built on Ark — an open-source Bitcoin Layer 2 protocol developed by Second.tech. Their work makes instant, self-custodial Bitcoin payments possible on Bitcoin as it exists today. No soft forks. No new opcodes. No compromises.
