The automated swap backend (asb) requires Monero funds, because Alice is selling Monero.
We use a hardcoded default wallet named asb-wallet. This wallet is opened upon startup.
If the default wallet does not exist it will be created.
This allows us to use .context instead of .map_err when calling
`latest_rate()`. For the static rate module, we simply fill in
`Infallible` which is actually better suited because it describes
that we are never using this error.
Note that because we are using `watch` channel, only a reference to the
channel value can be returned.
Hence, using custom Error that can be cloned to be able to
pass `Result` through the channel.
215: Debug log level in monero harness tests to see RPC responses r=da-kami a=da-kami
CI keeps failing when generating blocks, but response is only printed on debug level.
To investigate what is the problem change monero-harness log levels to debug.
Example failure:
https://github.com/comit-network/xmr-btc-swap/runs/1938109584
The failure happened when generating blocks, but without seeing the response error it is impossible to know what happened. Could not reproduce this problem locally.

209: Upgrade to bdk 0.4 r=thomaseizinger a=thomaseizinger
Effectively, this also means:
- Upgrading to rust-bitcoin 0.26
- Upgrading to miniscript 5
- Upgrading monero to 0.10
- Upgrading curve25519-dalek to 3
- Upgrading bitcoin-harness to rust-bitcoin 0.26 (https://github.com/coblox/bitcoin-harness-rs/pull/21)
- Upgrade `ecdsa_fun` to latest version
- Replace `cross_curve_dleq` with `sigma_fun` (to avoid an upgrade dance on that library)
I refrained from specifying `rev`s in the Cargo.toml because we have a lock-file anyway. This should allow us to update those dependencies easier in the future by just running `cargo update -p <dependency>`.

213: Properly calculate the confirmations for Bitcoin tx r=da-kami a=da-kami
Once the transaction was included into a block it has one confirmation - before inclusion it has zero.
current-block-height - transaction-block-height = zero; but that means one confirmation.
Hence, the confirmation calculation was adapted to: Current-block-height - (transaction-block-height - 1).
I could not think of a more elegant solution - if you have one please comment :)

To achieve this we also:
- upgrade rust-bitcoin to 0.26
- upgrade bitcoin-harness to latest version (which also depends bitcoin 0.26)
- upgrade to latest edcsa-fun
- replace cross_curve_dleq proof with sigma_fun (to avoid an upgrade dance over there)
205: Optimize GitHub workflow file r=thomaseizinger a=thomaseizinger

This allows us to completely skip the "Install Rust" step in CI
because the rust-toolchain file completely describes what we need.
The first invocation of cargo will simply install all the required
components.
Additionally, we make all caches dependant on the version of Rust
that we require.
200: Wait for refund if insufficient Monero is locked up r=da-kami a=da-kami
In a scenario where Alice does not lock up sufficient funds Bob should properly transition to refunds. At the moment the CLI just panics.
I noticed this when Alice accidentally had a different amount set than Bob. In the future this should not happen, because Alice provides the amount for Bob. However, in case Alice is malicious Bob should still transition correctly.

Usually, we can follow the rolling major tag (@v2) of actions.
However the recent release (2.1.4) is not yet included. See
https://github.com/actions/cache/issues/528 for more details.
We do want to depend on 2.1.4 because it contains a fix that allows
us to use the cache action MacOS. v2 also features better compression
and allows for multiple paths to be specified.
Building binaries and building tests results in different artifacts
inside the `target` directory. If we use distinct caches for these
commands, the caches are more useful because less code has to be
re-built.
206: Remove misplaced wallet sync call r=rishflab a=rishflab
These bdk wallet sync calls must of gotten lost during a rebase. Removed the call in build TxLock and added one when nectar starts up

178: Replace bitcoind wallet with bdk wallet r=rishflab a=da-kami
Create and pair bitcoind and electrs testcontainers using the same docker network and volume.
Follow-up to be fixed on top:
- [ ] Remove bitcoin-harness dependency and directly depend on https://github.com/thomaseizinger/rust-jsonrpc-client for the RPC client.

The bitcoind wallet required the user to run a bitcoind node. It was replaced with a bdk wallet which allows the user to connect to an electrum instance hosted remotely. An electrum and bitcoind testcontainer were created to the test the bdk wallet. The electrum container reads the blockdata from the bitcoind testcontainer through a shared volume. bitcoind-harness was removed as bitcoind initialisation code was moved into test_utils. The bdk wallet differs from the bitcoind wallet in that it needs to be manually synced with an electrum node. We synchronise the wallet once upon initialisation to prevent a potentially long running blocking task from interrupting protocol execution. The electrum HTTP API was used to get the latest block height and the transaction block height as this functionality was not present in the bdk wallet API or it required the bdk wallet to be re-synced to get an up to date value.
190: Do not pass Monero amount to the CLI r=D4nte a=D4nte
The CLI user only pass the Bitcoin amount they want to sell.
The CLI then do a quote request to nectar which provides the Monero amount the taker can get.

188: Tor cleanup r=da-kami a=da-kami
We never removed Tor install from CI. I don't think it should be necessary given that Tor was removed in code.
