Boltz
Non-custodial submarine swaps between on-chain Bitcoin, Lightning and Liquid — move between layers without an account.
Boltz performs non-custodial swaps between on-chain Bitcoin, Lightning and Liquid, so you can move value between layers without opening an account or trusting a middleman with your funds. The swaps use atomic techniques that either complete or refund — the service never takes custody.
It is the tool you reach for to refill Lightning liquidity, get on-chain funds into a Lightning wallet, or bridge to Liquid, all while staying self-custodial. That non-custodial guarantee is the whole point; the trade-off versus a custodial exchange is that you deal with swap mechanics and fees rather than a simple balance.
