lightning-upgradewallet -- Command to spend all P2SH-wrapped inputs into a Native Segwit output

SYNOPSIS

upgradewallet [feerate] [reservedok]

DESCRIPTION

upgradewallet is a convenience RPC which will spend all p2sh-wrapped Segwit deposits in a wallet into a single Native Segwit P2WPKH address.

feerate can be one of the feerates listed in lightning-feerates(7), or one of the strings urgent (aim for next block), normal (next 4 blocks or so) or slow (next 100 blocks or so) to use lightningd's internal estimates. It can also be a feerate is a number, with an optional suffix: perkw means the number is interpreted as satoshi-per-kilosipa (weight), and perkb means it is interpreted bitcoind-style as satoshi-per-kilobyte. Omitting the suffix is equivalent to perkb.

reservedok tells the wallet to include all P2SH-wrapped inputs, including reserved ones.

EXAMPLE USAGE

The caller is trying to buy a liquidity ad but the command keeps failing. They have funds in their wallet, but they're all P2SH-wrapped outputs.

The caller can call upgradewallet to convert their funds to native segwit outputs, which are valid for liquidity ad buys.
