It is sufficiently rare that we have to touch this stuff that I always have to re-discover where/how it is done. And it is impractical to grep for "bitcoin:" or "lightning:".
Putting this "master list" comment very close to the BITCOIN_BIP21_URI_SCHEME variable seems like a good spot - at least this is where I would look for it first.
The CoinGecko API failed as the Honduran Lempira currency returned
null as value, rendering the API unusable:

release.sh expects signed apks. if a non-releasemanager uses
release.sh to build it will build the apks unsigned and then
rename them to the same name as the signed apks. However
if the apks have already been built separately and are still named
*-unsigned.apk it will not detect them and instead try to build them
again. Instead it should just rename them to *-release.apk as if built
directly through release.sh.
Don't include first hop of the path,
this is the hop from us to the first node and we don't
need a payload for ourselves.
Also adds unittest checking this.
Factor out code from `send_onion_message_to` into a separate
function `_create_route_to_introduction_point` to make it
easier to reason about it and more testable.
This allows restricting blinded paths to channels that have sufficient receive
capacity for payment.
NOTE: this might have privacy issues, as this can be used to probe channel capacity.
Maybe randomize leeway?
@f321x: changed to use scid alias in create_blinded_path
- I noticed we were creating the RPC server unix domain socket with 0o775.
Instead of hunting down each individual line we create files/dirs, we should
just set a restrictive umask by default. We can still use chmod to relax this
for individual files. -- but we should try to be secure by default
- note: bitcoin core does the same
https://github.com/bitcoin/bitcoin/blame/2fe76ed8324af44c985b96455a05c3e8bec0a03e/src/common/system.cpp#L92
- the umask is set in run_electrum as opposed to __init__.py so that we don't side-effect use-cases where electrum is imported as a library
Adds a CI step to the Cirrus CI which will run claude code on the diff
of a Pull Request and fail if it finds critical security vulnerabilities
or serious code issues. Optinally it can be given a GitHub api key to
create a comment in the pull request.
Followup #10541.
Fixes tests.regtest.TestLightningSwapserver.test_swapserver_forceclose.
In the regtest bob would now signal trampoline support due to #10541 and
include Alice into the invoice trampoline as he is connected to Alice.
Alice would then try to add herself onto the trampoline route, causing
the payment to fail.
Check if self.network before trying to access it. This would trigger an
exception when toggling the trampoline checkbox in offline mode:

Even though the NIP-47 specification kind of defines that requests should
always pass a params dict in their request i witnessed way too often
that clients don't include it in some requests where it is technically
not neccessary and we fail on it.
Handling this gracefully improves compatibility without obvious
downsides.
Add unittest that verifies we only include r_tags for trampoline nodes
if we signal trampoline support in the invoice_features and only signal
trampoline support if we use trampoline or have only open trampoline
channels.
Make the trampoline signaling in bolt11 invoices dependent upon all
unfrozen channels being with trampoline peers instead of the trampoline
config.
Stops automatically freezing non-trampoline channels for receiving if
trampoline is enabled.
One effect of this change is that now we don't signal trampoline support
anymore in the invoice even if trampoline is enabled, if one of the
channels is with a non trampoline peer.
To limit attack surface.
Context:
- both in daemon mode and in GUI mode, we start an RPC server
- the RPC server uses HTTP basic auth, with a random password that is saved in the config file
- read access to the config file implies access to the RPC server
- the traffic is unencrypted
- by default the server listens
- on Windows, on localhost TCP
- all other platform, via unix domain sockets
- if an attacker can listen to localhost TCP traffic, and there was traffic
- they could see the plaintext RPC password and issue their own commands
- e.g. if wireshark was already installed on the system, this might not require root access
- the "ping" and "gui" commands are used by everyday operations that affect most users:
- "ping" is used when trying to launch a second instance of electrum, to contact the first instance and enforce "singleton" behaviour
- "gui" is used for URI handling (`$ xdg-open bitcoin:asdasd`)
- many other sensitive commands, that operate on wallets, require *also* the wallet password
- but note that wallet.unlock can be used by the user to bypass this and store the wallet password in memory (exposed in GUI)
I propose locking down the RPC server when running in GUI mode:
- we still start it, as it is used for "ping" and "gui" RPCs, however we disable all other RPCs
- we could opt-in enable it, using a config var, except that ofc would not help against an attacker that has filesystem write access to the config file
- so I think it's even safer to just "hardcode" disable it: however the functionality is useful for development
- I propose we branch based on `constants.net.TESTNET`
- an alternative we could branch on that is hard to fake is `is_git_clone` in run_electrum
