The short version

What changed, and why it matters

This change improves the Trezor hardware wallet's Solana transaction confirmation screen. When a transaction contains an unknown program (smart contract), the device now shows the actual program ID instead of a generic 'Unsupported program' label. This helps users make a more informed decision before approving a transaction, but it is a user-interface improvement rather than a fix for a code vulnerability.

Recommended action

No urgent action required. Treat as a normal firmware improvement. Users benefit from clearer transaction details, but the change does not address an exploitable vulnerability.

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
