Can do

What Wavelength supports

  • Self-custodial keysThe seed stays on the device. Wavelength does not hold it.
  • BOLT 11 LightningSend and receive. Lightning is an atomic swap. You see the fee before you confirm.
  • On-chain boardingA Bitcoin address that Wavelength settles into the wallet.
  • On-chain sendPay a Bitcoin address. Cooperative leave is this path.
  • Unilateral exitWavelength can return funds to the Bitcoin chain without the operator. The wallet shows the cooperative path first.
  • RestoreThe recovery phrase rebuilds the wallet, including funds still in flight.
  • ActivityBalance, pending in, pending out, and the payment list.
  • Free refreshOpen the wallet about every two weeks. Wavelength renews the exit window at no service fee inside that window.
  • PasskeysWavelength supports platform passkeys. This build uses a device password.
  • Agentswavecli mcp serve exposes the daemon to an agent. Seeds stay off that channel. A receive-only macaroon cannot sign.
