- Generate Segwit addresses by invoking 'mmgen-addrgen' with the '--type segwit' option - Import Segwit addresses into the tracking wallet as usual - Segwit and legacy MMGen addresses are distinguished by 'S' and 'L' identifiers in the tracking wallet and command line Transaction example: mmgen-txcreate F00BAA12:L:21,1.23 F00BAA12:S:1 (spend 1.23 BTC to legacy address 21 of your default wallet (with Seed ID F00BAA12) and send the change to Segwit address 1) Segwit and legacy addresses for a given seed are generated from different sub-seeds so are cryptographically unrelated to each other. Since MMGen's legacy P2PKH addresses are uncompressed, use of the new Segwit addresses significantly reduces transaction size. Until Segwit activation on mainnet, users can try out the new functionality on testnet or in regtest mode.
