Boltz swaps were suspended on 3 August 2026, according to primary notices from Blockstream and Bull Bitcoin. A current Boltz restart is not established. Bull Bitcoin separately restored several BULL Wallet functions on 20 October; that wallet update does not establish resumption of the Boltz service. This profile retains the historical mechanics relevant to outstanding swaps.[7][8][9]

BULL Wallet: restoration separate from Boltz status
| Function | Operator update from 20 October 2026 | Boundary |
|---|---|---|
| Lightning send/receive | Restored. | Wallet functionality; not proof that Boltz restarted.Source 9 |
| Liquid transfers and L-BTC→BTC | Restored. | L-BTC→BTC requires a fresh receiving address.Source 9 |
| BTC→L-BTC conversion | Still unavailable in the restoration notice. | Reverse direction has different availability.Source 9 |
| Ordinary on-chain Bitcoin transfers | Available separately. | Wallet balances are distinct from an outstanding swap.Source 9 |

Historical swap types
Historical costs and unavailable live quotes
Sections ↑The old fee and API pages describe a quote-based service. They are not evidence that swaps can presently execute, and this review does not reproduce a stale percentage as an active offer. An outstanding transaction must be reconciled against the quote actually accepted for that swap.[3][7]

| Service charge | Swap operator economics | Original quote.Source 3Source 4 |
| Miner fee | On-chain transaction cost | Chain receipt and fee.Source 3Source 4 |
| Lightning routing | Payment-route cost where applicable | Wallet payment details.Source 3Source 4 |
| Refund cost | Additional chain transaction may be required | Actual contract/refund path.Source 3Source 4 |

Transaction state determines the next investigation
| Observed state | Evidence | Do not assume |
|---|---|---|
| Nothing broadcast | No source-chain transaction | A quote reserved an executable swap.Source 4 |
| Source transaction confirmed | Source hash and output | Destination payout already occurred.Source 4 |
| Claim visible | Destination or claim hash | A wallet display alone proves finality.Source 4 |
| Refund visible | Refund hash and amount | Refund returned the gross original amount.Source 4 |

Historical data needed to identify a swap
| Record | Purpose |
|---|---|
| Swap identifier | Match the interface/API request.Source 5Source 4 |
| Source and destination network | Identify the actual chains.Source 5Source 4 |
| Transaction hashes | Trace broadcast and confirmation.Source 5Source 4 |
| Refund/recovery information | Required by the applicable contract path.Source 5Source 4 |
Contract control and recovery boundaries
Sections ↑Historical Boltz swaps used conditional contracts rather than a conventional multi-asset exchange balance. That design does not make website availability irrelevant: the user may still need their original recovery data, a compatible client and the correct timelock state. Preserve those records privately; support does not need a wallet seed phrase.[4][6]
Reference table08
Historical recovery paths are not interchangeable
| Path | Dependency | Availability statement |
|---|---|---|
| Cooperative refund | Service cooperation/API | Current endpoint availability not verified.Source 8Source 4 |
| Unilateral refund | Contract conditions and recovery data | Cannot be treated as an instant universal refund.Source 8Source 4 |
| Completed claim | Successful settlement on chain | Different from an unclaimed locked swap.Source 8Source 4 |
Reference table09
Wallet holdings versus swap exposure
| Asset location | Control boundary | Investigation focus |
|---|---|---|
| Ordinary wallet balance | Wallet keys and network | Wallet transaction history.Source 8Source 4 |
| Conditional swap output | Contract and timelock | Original swap data.Source 8Source 4 |
| Already delivered output | Destination wallet | Receiving-chain confirmation.Source 8Source 4 |
Availability before any new transaction

Requirements before treating a future restart as live
| Evidence | Reason |
|---|---|
| Official restart notice | A historical guide is insufficient.Source 7Source 2 |
| Available pair and executable quote | A reachable homepage is insufficient.Source 7Source 2 |
| Current terms and service counterparty | Old ownership or terms may have changed.Source 7Source 2 |

How to use this historical profile

The recorded suspension is the controlling fact until a reliable, current restart announcement and executable route are verified.[7][8]
