- trampoline is enabled by default in config, to prevent download of `gossip_db`.
(if disabled, `gossip_db` will be downloaded, regardless of the existence of channels)
- if trampoline is enabled:
- the wallet can only open channels with trampoline nodes
- already-existing channels with non-trampoline nodes are frozen for sending.
- there are two types of trampoline payments: legacy and end-to-end (e2e).
- we decide to perform legacy or e2e based on the invoice:
- we use trampoline_routing_opt in features to detect Eclair and Phoenix invoices
- we use trampoline_routing_hints to detect Electrum invoices
- when trying a legacy payment, we add a second trampoline to the path to preserve privacy.
(we fall back to a single trampoline if the payment fails for all trampolines)
- the trampoline list is hardcoded, it will remain so until `trampoline_routing_opt` feature flag is in INIT.
- there are currently only two nodes in the hardcoded list, it would be nice to have more.
- similar to Phoenix, we find the fee/cltv by trial-and-error.
- if there is a second trampoline in the path, we use the same fee for both.
- the final spec should add fee info in error messages, so we will be able to fine-tune fees
- print the test name before each test
- start only needed agents (alice, bob, carol)
- set settle_delay using setconfig instead of restarting daemon
- test the watchtower ctn in test_watchtower
- persisted states are saved
- state transitions are checked
- transient states are stored in channel.peer_state
- new channel states: 'PREOPENING', 'FUNDED' and 'REDEEMED'
- upgrade storage to version 21
- allow 'spend max' when opening a channel (fixes#5698)
- display amount minus fee when 'max' buttons are pressed
- estimate fee of channel funding using a template with dummy address
- use InvoiceInfo (NamedTuple) for normal operations,
because lndecode operations can be very slow.
- all invoices/requests are stored in wallet
- invoice expiration detection is performed in wallet
- CLI commands: list_invoices, add_request, add_lightning_request
- revert 0062c6d695 because it forbids self-payments
- commands are async
- the asyncio loop is started and stopped from the main script
- the daemon's main loop runs in the main thread
- use jsonrpcserver and jsonrpcclient instead of jsonrpclib
- remove remote_commitment_to_be_revoked
- pass old ctns to lnsweep.create_sweeptxs_for_watchtower
- store the ctn of sweeptxs in sweepStore database
- request the highest ctn from sweepstore using get_ctn
- send sweeptxs asynchronously in LNWallet.sync_with_watchtower
- add functions to lnsweep
- lnworker: analyze candidate ctx and htlc_tx
- watchtower will be optional
- add test for breach remedy with spent htlcs
- save tx name as label
- fix bug in lnsweep: lnwatcher transactions were indexed by prev_txid
- add test for breach remedy with unsettled htlcs
- add timeout option to lnpay, and replace DO_NOT_SETTLE with SETTLE_DELAY
so that we can read intermediate commitment tx in regtest
