Testing on signet

Documentation of testing options with the wider network since the dev setup makes is possible to start a signet instance.

General notes about signet

Advantages

• it is a network where intreaction is possible with other instances and projects
• funds are worthless just like on testnet
• the derivation paths are same as on testnet
• reliable blocktimes
• no block-storms
• small blockchain (IBD ~ 10 mins on a laptop)
• Faucets are available (see below)

Disadvantages

• no lndmon support yet https://github.com/lightninglabs/lndmon/issues/80
• no Loop support yet https://github.com/lightninglabs/loop/issues/522
• fewer nodes on the network
• staging would need an accounting reset when converting (might be an advantage)
• no known 3rd party services / test shops available
• pending in:

• create a custodial account and top up over LN

OBW

• for Android only with LN support

Sparrow Wallet

Supports onchain only, but works well with Taproot accounts. To use it with signet open: menu - Tools - Restart in Testnet and set a Private Electrum server serving signet like: node202.fra.mempool.space port: 60602 with SSL.`

Electrum Wallet

• Support onchain (no Taproot yet) and LN, but couldn't send or receive lightning payments on signet with electrum yet.
• start with the signet flag eg:

  electrum-4.4.0-x86_64.AppImage --signet
• menu - Wallet - Information and restart to activate lightning

Blink staging node to open channels to
