This diff introduces a new "approvals" mechanism that alters the swap flow by requiring explicit user intervention before the Bitcoin lock transaction is broadcast. Previously, the Bitcoin lock was executed automatically without any user prompt. Now, the backend defines `ApprovalRequestType` (e.g. a `PreBtcLock` variant with details like `btc_lock_amount`, `btc_network_fee`, and `xmr_receive_amount`) and `ApprovalEvent` (with statuses such as `Pending`, `Resolved`, and `Rejected`). The method `request_approval()` in the `TauriHandle` struct uses a oneshot channel and concurrent timeout handling via `tokio::select!` to wait for the user's decision. Based on the outcome—explicit approval or timeout/rejection—the approval event is emitted through the `emit_approval()` helper, thereby gating the subsequent broadcast of the Bitcoin lock transaction.
On the UI side, changes have been made to reflect the new flow; the modal (for example, in `SwapSetupInflightPage.tsx`) now displays the swap details along with explicit action buttons that call `resolveApproval()` via RPC when clicked. The Redux store, selectors, and hooks like `usePendingPreBtcLockApproval()` have been updated to track and display these approval events. As a result, the overall functionality now requires the user to explicitly approve the swap offer before proceeding, ensuring they are aware of the swap's key parameters and that the locking of funds occurs only after their confirmation.
This pull requests
- Adds rust native support for the `asb` to listen on an onion service. Previously we were depedent on a seperately running `torc` client. Instead we now use [arti](https://tpo.pages.torproject.net/core/arti/), a rust implementation of the tor protocol.
- Removes the `tor.control_port` and `tor.socks5_port` property from the config of the `asb`
- Adds a new `tor.register_hidden_service` boolean property to the config of the `asb` which when enabled automatically runs a hidden service at startup
- Adds a new `tor.hidden_service_num_intro_points` config property to specify how many introduction points to register the onion service at
- Adds support for the `cli` to dial onion addresses
This is dependent on https://github.com/umgefahren/libp2p-tor/pull/24
Closes https://github.com/UnstoppableSwap/core/issues/16
- Upgrade `sqlx` to `0.8`
- Use `arti_client@0.24` in combination with [`libp2p-community-tor`](https://crates.io/crates/libp2p-community-tor/0.4.1). https://github.com/umgefahren/libp2p-tor/pull/18 was required for this.
- Display spinner in GUI while Tor circuits are being established
- Remove unused dependencies (`once_cell`, `tauri-plugin-devtools`, `digest`, `hyper`, `itertools`, `erased_serde`)
- Bundle roboto font from npm registry
Our libp2p version is out of date, and we need to tackle the upgrade even though it's a significant undertaking. This'll also fix some other [issues](https://github.com/UnstoppableSwap/core/issues/95).
## This PR includes the following changes:
- Breaking network protocol change: The libp2p version has been upgraded to 0.53 which includes breaking network protocol changes. ASBs and CLIs will not be able to swap if one of them is on the old version.
- ASB: Transfer proofs will be repeatedly sent until they are acknowledged by the other party. This fixes a bug where it'd seem to Bob as if the Alice never locked the Monero. Forcing the swap to be refunded.
- CLI: Encrypted signatures will be repeatedly sent until they are acknowledged by the other party
- CLI+ASB: Libp2p network errors in request-response protocols are now propagated throught the event loop channels. This allows the caller to retry if an error occurs (e.g timeout)
