## **Description**

Bumps the Solana, Stellar, and Tron wallet snaps to the versions
released in internal-snaps `22.0.0`:

- `@metamask/solana-wallet-snap`: `^7.2.0` → `^7.3.0`
- `@metamask/stellar-wallet-snap`: `^2.0.0` → `^2.1.0`
- `@metamask/tron-wallet-snap`: `^4.3.1` → `^4.4.0`

All three are backwards-compatible minor updates; no application code
changes are required.

### @metamask/solana-wallet-snap 7.3.0

- Remove the temporary fallback that injected `https://metamask.io` as
the request origin when `keyring_submitRequest` was called without one
([MetaMask#533](MetaMask/internal-snaps#533)).

### @metamask/stellar-wallet-snap 2.1.0

- `confirmSend` now throws when signing or submission fails after the
user confirms, instead of returning a JSON error response
([MetaMask#550](MetaMask/internal-snaps#550)).
- Bump `@stellar/stellar-sdk` from `^17.2.1` to `^17.4.0`
([MetaMask#545](MetaMask/internal-snaps#545)).
- Retry transient Token API, Price API, Security Alerts API, RPC, and
Horizon failures with bounded timeouts and circuit breaking
([MetaMask#534](MetaMask/internal-snaps#534),
[MetaMask#551](MetaMask/internal-snaps#551)).
- Fix `onAmountInput` to accept the optional destination as `toAddress`
instead of `to`
([MetaMask#558](MetaMask/internal-snaps#558)).

### @metamask/tron-wallet-snap 4.4.0

- Support `VoteWitnessContract` and `AccountPermissionUpdateContract`
transactions by upgrading TronWeb to 6.5.1
([MetaMask#561](MetaMask/internal-snaps#561)).
- Align transaction security warning copy and scan-loading behavior with
user preferences
([MetaMask#557](MetaMask/internal-snaps#557)).

for RPC, Horizon and HTTP clients, `@stellar/stellar-sdk` upgrade,
`onAmountInput` `toAddress` fix, `confirmSend` now throws after
confirmation failures)
- `@metamask/tron-wallet-snap` `4.3.1` → `4.4.0` (minor:

([MetaMask#543](MetaMask/internal-snaps#543)).

```gherkin
Feature: Bitcoin and non-EVM wallet flows

  Scenario: user views account assets
    Given the user has Bitcoin, Solana, Stellar, and Tron accounts with assets
    When user opens the wallet and switches between those networks
    Then the assets and balances load successfully

  Scenario: user sends funds on each network
    Given the user has funds on Bitcoin, Solana, Stellar, and Tron
    When user sends funds on each network
    Then the fee estimate and confirmation are displayed correctly
    And the transaction is broadcast and completes successfully

#### Performance checks (if applicable)

- [x] I've tested on Android
  - Ideally on a mid-range device; emulator is acceptable
- [x] I've tested with a power user scenario
- Use these [power-user
SRPs](https://consensyssoftware.atlassian.net/wiki/spaces/TL1/pages/edit-v2/401401446401?draftShareId=9d77e1e1-4bdc-4be1-9ebb-ccd916988d93)
to import wallets with many accounts and tokens
- [x] I've instrumented key operations with Sentry traces for production
performance metrics
- See [`trace()`](/app/util/trace.ts) for usage and
[`addToken`](/app/components/Views/AddAsset/components/AddCustomToken/AddCustomToken.tsx#L274)
for an example
