update tron swapkit memo ui
✓ Descriptive subject✓ Names a concrete action or component! No meaningful explanatory body
What changed, and why it matters
This commit adds a new on-screen display for Tron cryptocurrency swaps that use a memo starting with '=:' (called 'SwapKit' style). It shows the user extra details such as the destination asset, destination address, raw amount, memo, and expiration time before signing. The change is mostly a UI feature, but it also parses and displays user-controlled memo text, which could be abused to mislead the user if the memo contains crafted text. There is no evidence in the commit that this is a security fix or that the vendor called it a vulnerability.
Recommended action
Treat as a feature commit, but review the new memo-parsing UI path for spoofing risks. Ensure the memo field has strict length limits and that the parsed destination asset/address is clearly labeled as 'from memo' so users cannot be tricked by a malicious memo into approving an unintended swap. Consider fuzzing the memo parser and verifying that oversized or malformed memos do not crash the device or truncate security-critical labels.
Security signals we found
01
New UI path triggered by attacker-influenced memo prefix '=:'
02
Memo content is parsed with strchr on ':' and rendered as destination asset/address, creating a UI spoofing surface
03
No visible length/charset validation on memo before display
04
Signing flow unchanged; no cryptographic bypass introduced
05
Adds a 'Check the Vault Address' QR link to tronscan.org for swap destination addresses
Evidence from the diff
The patch introduces a dedicated ViewType::TronSwapTx / REMAPVIEW_TRX_SWAP path for Tron transactions whose memo begins with ‘=:’ (detected in rust/rust_c/src/common/ur_ext.rs). It extends the Rust parser to expose raw_value, memo, and expiration fields, wires them through FFI structs, and adds C UI callbacks (GetTrxSwapDstAsset, GetTrxSwapDstAddress, GetTrxMemo, etc.) plus a JSON page layout for the hardware wallet screen. The memo is split on ‘:’ characters to derive destination asset/address for display. The signing logic itself is unchanged; the same QR/UR signing helpers are reused. No input-length sanitization is visible in the new UI getters beyond the existing safe string copy helpers.
