+# Plan: Track unsupported incoming mints in `other_mints` and include them in balances
+
+## Goal
+
+When a Cashu token arrives from a mint that is **not** in `settings.cashu_mints`, we currently create/use a wallet for that mint and swap value into the primary mint. Any change/surplus left behind after `melt()` remains in the foreign `token_wallet`, but that balance is not surfaced by `fetch_all_balances()` because it only iterates over configured mints.
+
+This plan adds persistent tracking for those foreign mints in a new database table called `other_mints`, and updates balance reporting to include them.
+
+---
+
+## Current behavior
+
+### Incoming unsupported mint flow
+
+In `routstr/wallet.py`:
+
+- `recieve_token()` deserializes the token
+- if `token_obj.mint not in settings.cashu_mints`, it calls `swap_to_primary_mint(token_obj, wallet)`
+- `swap_to_primary_mint()` calls `token_wallet.melt(...)` to pay the primary mint invoice
+
+### Important detail: change is retained, not discarded
+
+The underlying Cashu wallet library keeps any melt change:
+
+- `Wallet.melt()` constructs blank outputs for change
+- when the melt succeeds, returned change is reconstructed into proofs
+- those proofs are appended to `self.proofs` and stored in the wallet DB
+
+So surplus from unsupported mints is **not discarded**, but it may become invisible operationally.
+
+### Visibility problem
+
+`fetch_all_balances()` currently only loops over:
+
+- `settings.cashu_mints`
+- units `sat` and `msat`
+
+This means balances left on unsupported mints are not shown in admin balance reporting.
+
+---
+
+## Proposed design
+
+## 1. Add a new DB table: `other_mints`
+
+Add a small table in `routstr/core/db.py` to persist unsupported mints we have seen in incoming tokens.
+
+Suggested schema:
+
+- `mint_url: str` primary key
+- `created_at: int`
+- `last_seen_at: int`
+
+Minimal model:
+
+```python
+class OtherMint(SQLModel, table=True):
+    __tablename__ = "other_mints"
+
+    mint_url: str = Field(primary_key=True)
+    created_at: int = Field(default_factory=lambda: int(time.time()))
+    last_seen_at: int = Field(default_factory=lambda: int(time.time()))
+```
+
+Why minimal:
+
+- the only required function is mint discovery/tracking
+- unit handling can remain dynamic via existing balance queries over `sat` and `msat`
+
+---
+
+## 2. Add DB helpers for `other_mints`
+
+In `routstr/core/db.py`, add helper functions:
+
+### `register_other_mint(mint_url: str) -> None`
+
+Behavior:
+
+- if the mint is not present, insert it
+- if it already exists, update `last_seen_at`
+
+### `list_other_mints(session) -> list[str]`
+
+Behavior:
+
+- return all tracked unsupported mint URLs
+
+Optional later:
+
+- `delete_other_mint(...)`
+- admin cleanup helpers
+
+---
+
+## 3. Register unsupported mints during token receipt
+
+Update `recieve_token()` in `routstr/wallet.py`.
+
+Current logic:
+
+```python
+if token_obj.mint not in settings.cashu_mints:
+    return await swap_to_primary_mint(token_obj, wallet)
+```
+
+Planned logic:
+
+```python
+if token_obj.mint not in settings.cashu_mints:
+    await db.register_other_mint(token_obj.mint)
+    return await swap_to_primary_mint(token_obj, wallet)
+```
+
+Why here:
+
+- this is the earliest reliable point where we know the mint came in via an actual token
+- this is exactly the path that can leave foreign-mint change behind
+- it avoids needing to infer unsupported mints later from wallet internals
+
+---
+
+## 4. Update `fetch_all_balances()` to include `other_mints`
+
+Current behavior only includes configured mints.
+
+Planned behavior:
+
+- load tracked unsupported mints from DB
+- combine them with `settings.cashu_mints`
+- dedupe while preserving order
+- fetch balances for all tracked mints across requested units
+
+Conceptual flow:
+
+```python
+tracked_mints = dedupe(settings.cashu_mints + other_mints_from_db)
+```
+
+Then existing per-mint/per-unit balance logic can remain mostly unchanged.
+
+This ensures that retained change on unsupported mints becomes visible in admin balance reporting.
+
+---
+
+## 5. Add a balance source marker
+
+Extend `BalanceDetail` in `routstr/wallet.py` to identify whether a balance row comes from a configured mint or an `other_mints` entry.
+
+Suggested field:
+
+- `source: str` with values:
+  - `"configured"`
+  - `"other"`
+
+Updated shape:
+
+```python
+class BalanceDetail(TypedDict, total=False):
+    mint_url: str
+    unit: str
+    source: str
+    wallet_balance: int
+    user_balance: int
+    owner_balance: int
+    error: str
+```
+
+Why this helps:
+
+- admin can distinguish normal configured wallet balances from foreign/unsupported balances
+- avoids confusion if unexpected mint URLs show up in the balances API/UI
+
+---
+
+## 6. Admin/API impact
+
+Backend impact is minimal because `/admin/api/balances` already returns `fetch_all_balances()` output.
+
+Effects:
+
+- supported mints continue to show as before
+- tracked unsupported mints will also appear
+- UI can optionally display the new `source` field
+
+No API contract break is expected if the frontend ignores unknown fields.
+
+---
+
+## 7. Payout behavior: do not change in phase 1
+
+`periodic_payout()` currently only iterates over `settings.cashu_mints`.
+
+Recommendation for this change:
+
+- **do not** expand `periodic_payout()` to include `other_mints` yet
+- only improve visibility through balance reporting
+
+Reason:
+
+- automatic payout from unsupported/foreign mints may be operationally undesirable
+- visibility should come first, automation second
+
+Possible future phase:
+
+- add optional sweeping/payout support for `other_mints`
+- or provide an admin-triggered withdrawal/sweep flow
+
+---
+
+## 8. Logging improvements (optional)
+
+Optional follow-up improvement in `swap_to_primary_mint()`:
+
+- capture the return value from `token_wallet.melt(...)`
+- if feasible, log any reported change amount
+- otherwise, rely on wallet balance reporting to surface residual amounts
+
+This is useful but not required for the first implementation.
+
+---
+
+## Files to change
+
+### `routstr/core/db.py`
+
+Add:
+
+- `OtherMint` SQLModel
+- `register_other_mint()`
+- `list_other_mints()`
+
+### `migrations/versions/<new_revision>_add_other_mints_table.py`
+
+Create migration to add the `other_mints` table.
+
+### `routstr/wallet.py`
+
+Update:
+
+- `recieve_token()` to register unsupported mints
+- `BalanceDetail` to include `source`
+- `fetch_all_balances()` to include both configured and tracked unsupported mints
+
+### `routstr/core/admin.py`
+
+Likely no backend changes required unless a dedicated `other_mints` API is desired.
+
+---
+
+## Behavior rules
+
+### Register a mint when
+
+- an incoming token is processed
+- the token mint is not in `settings.cashu_mints`
+
+### Do not remove automatically when
+
+- balance reaches zero
+
+Reason:
+
+- historical visibility is useful
+- avoids flapping entries in the admin balance list
+- mint may receive additional unsupported tokens later
+
+Potential future enhancement:
+
+- admin endpoint to prune zero-balance `other_mints`
+
+---
+
+## Edge cases
+
+### A mint later becomes configured
+
+If a mint in `other_mints` is later added to `settings.cashu_mints`:
+
+- deduplication prevents duplicate balance rows
+- `source` should resolve to `configured`
+
+### Unsupported mint with zero balance
+
+A tracked unsupported mint may show zero balances.
+
+Initial recommendation:
+
+- allow it to appear
+- consider later filtering zero-balance `other` rows if the UI becomes noisy
+
+### Units
+
+Balance fetching can continue to query both `sat` and `msat` for each tracked mint.
+
+If a mint has no proofs in one unit, current error/zero handling can continue to apply.
+
+---
+
+## Test plan
+
+### DB tests
+
+- registering a new unsupported mint inserts a row
+- registering the same mint again updates `last_seen_at` without duplication
+- listing other mints returns expected mint URLs
+
+### Wallet tests
+
+#### `recieve_token()`
+
+- when mint is unsupported, `db.register_other_mint()` is called before swap
+- when mint is configured, `db.register_other_mint()` is not called
+
+#### `fetch_all_balances()`
+
+- includes configured mints
+- includes `other_mints` from DB
+- dedupes if a mint exists in both configured and other lists
+- sets `source` correctly
+
+### Regression tests
+
+- existing trusted mint balance reporting remains unchanged
+- `/admin/api/balances` continues to work
+
+---
+
+## Recommended implementation order
+
+1. Add `OtherMint` model to `routstr/core/db.py`
+2. Add Alembic migration for `other_mints`
+3. Add `register_other_mint()` and `list_other_mints()` helpers
+4. Update `recieve_token()` to register unsupported mints
+5. Update `fetch_all_balances()` to union configured + tracked other mints
+6. Add `source` to `BalanceDetail`
+7. Add/adjust tests
+
+---
+
+## Summary
+
+This change solves an operational visibility problem:
+
+- unsupported incoming mints can leave retained change in foreign wallets
+- those funds are currently preserved but not surfaced in balance reporting
+- introducing `other_mints` makes those mints discoverable and auditable
+- expanding `fetch_all_balances()` ensures their balances are visible in admin tooling
+
+Recommended scope for the first pass:
+
+- track unsupported mints in DB
+- include them in balance reporting
+- mark them as `source="other"`
+- do not yet change payout/sweeping behavior
