Finding a exchange to buy L-BTC that works for you might be difficult so an easy way to get L-BTC is to acquire BTC first and then swap or peg-in for L-BTC.

If buying BTC from an exchange that doesn't offer Lighting withdrawals or swapping existing BTC, you can use boltz.exchange to swap BTC for L-BTC (0.1% swap fee) or sideswap.io/peg-in-out/ to perform a peg-in (0.1% peg-in fee).

Depending on the amount pegged in with SideSwap it might take 2 or 102 confirmations. Check their FAQ for details.

With Boltz, the L-BTC is sent as soon as the LN payment is received.

SideSwap also has it's own app but I suggest you use Blockstream Green to generate the receiving addresses for Boltz or SideSwap.

If buying BTC from an exchange that do LN withdraws or swapping existing BTC on Lightning, you can use boltz.exchange to swap into Liquid (0.25% swap fee).

For peg-out from L-BTC to BTC, you can use boltz.exchange (0.5% swap fee) or sideswap.io/peg-in-out/ (0.1% pet-out fee). See their FAQ for details.
