Boltz Review 2026: Non-Custodial Bitcoin Bridge Reportedly Paused

Boltz is a non-custodial Bitcoin bridge that swaps between Bitcoin layers, including the Lightning Network, Liquid and Rootstock. It began as an alpha, account-free exchange built on Lightning. It later grew into a broader swap service listed on Rootstock and Arbitrum.

A news report dated August 2026 says Boltz has suspended its Bitcoin swap service after a series of AI-assisted attacks caused losses for the bootstrapped five-person company. For that reason this page treats the project as inactive. Anyone considering it should confirm the current status through the project's own channels.

Before that, Boltz had launched Boltz Pro in late 2024. It let users supply liquidity and earn sats from swaps. The project does not list a token of its own, and no audits are listed.

Boltz is a swap service between Bitcoin layers. A user who holds bitcoin on one layer, such as the main chain, can swap into another, such as the Lightning Network, without opening an account. Boltz started as a trust-minimized, account-free exchange built on Lightning and later extended to Liquid and Rootstock.

The non-custodial claim rests on atomic-swap-style mechanics. In general, such swaps lock funds under conditions that either let the counterparty claim them once the swap completes, or let the user refund them after a timeout. The user does not hand funds to a custodian who could simply keep them.

Boltz also needs its own liquidity on each side of a swap. Boltz Pro, launched in December 2024, let outside users supply wallet and Lightning channel liquidity and earn sats from swaps in return.

Swap fees are not published in the material available, so no percentage or fixed rate can be quoted here. Any fee would normally be shown in the swap interface before a user confirms.

Boltz Pro let liquidity providers earn sats from swaps, which implies the service charged fees that were shared with providers. The Telegram bot also let Pro users pick a fee level for a pair. Users also pay normal network fees on Bitcoin, Lightning or Rootstock for their side of a swap.

Boltz describes its swaps as non-custodial, which removes the risk of a custodian running off with deposits. It does not remove smart-contract, liquidity or operational risk. No audits are listed for the project, and it has not published a licence or regulatory status in the material available.

One news report says AI-assisted attacks caused losses for the company and led it to suspend swaps. The report describes a five-person bootstrapped team. Treat any information about the exact attack method and losses as unconfirmed until the team publishes details. Do not send funds unless the project clearly confirms the service is running.

Boltz was built for Bitcoin users who move value between layers, especially Lightning users who want non-custodial swaps. It also targeted liquidity providers who wanted to earn sats through Boltz Pro. Given the reported suspension, it is mainly of interest now to people researching Bitcoin bridges or holding open swaps.
