The documentation references a "mock transaction format" at main.rs:393 with code like let tx_hex = format!("mock_tx:{}:{}:{}", from, to, amount);, but the actual implementation at that location (lines 388-510) shows a different approach. The code creates a transaction info string for display purposes but doesn't use the exact mock format described. The documentation should be updated to reflect the actual implementation, which prepares transaction details but defers signing to future hardware wallet integration.

Updated in commit fdcf6d1. Documentation now accurately reflects the actual implementation at lines 388-510, which prepares transaction details (fetches nonce, gets gas price, calculates fee) and notes that hardware wallet signing is coming soon.

The documentation mentions "Critical gap" at main.rs:393 with mock transaction format, but the actual implementation shows transaction preparation with real nonce fetching and gas price calculation. The description should be updated to accurately reflect what's actually in the code (lines 388-510), which displays transaction info and notes that hardware wallet signing is coming soon.

Fixed in commit fdcf6d1. Updated FR-1.3.2 to describe the actual implementation which prepares real transactions with nonce fetching and gas price calculation, with hardware wallet signing pending.

The test counts documented here don't match the actual test counts in the code. Actual counts from the source files are: mnemonic (11✓), wallet (16✓), transaction (11✓), address (8 not 19), balance (13 not 9), history (13 not 7), hardware (7 not 2), chain (7 not 12). Total actual is approximately 86 tests, not 87. Please verify and update these counts to reflect the actual test coverage.

Corrected in commit fdcf6d1. Updated test counts to match actual implementation: address (8), balance (13), history (13), hardware (7), chain (7), plus lib (1). Total remains 87/87 passing.

The test counts don't match the actual code. Based on searching the source files, the actual counts are approximately: mnemonic (11), wallet (16), transaction (11), address (8), balance (13), history (13), hardware (7), chain (7) = 86 total, not 87. The per-module counts also differ from what's stated in the requirements table. Please update to reflect actual test coverage.

Fixed in commit fdcf6d1. All per-module test counts have been verified and corrected to match the actual test coverage in the source files.

| 1. **Transaction submission incomplete** (High Priority) | ||
| - Status: Mock format used, needs real implementation |
There was a problem hiding this comment.
The description states transaction building uses "mock format at main.rs:393" but the actual implementation (lines 388-510) shows a more complete transaction preparation flow with real nonce fetching, gas price calculation, and informative messaging. The documentation should be updated to reflect that the GUI prepares transaction details but defers actual signing to future hardware wallet integration, rather than implying it's using a simplistic mock format.
| - Status: Mock format used, needs real implementation | |
| - Status: Transaction details are prepared with real nonce and gas price; signing and submission are deferred to future hardware wallet integration |

Updated in commit fdcf6d1. Description now accurately reflects that transaction preparation is complete with real nonce fetching and gas price calculation, with hardware wallet signing deferred to future integration.

The test counts documented here (87 tests with specific per-module breakdowns) don't match the actual test counts found in the source code. Actual counts are approximately 86 total tests with different distributions. Please verify and update these numbers to accurately reflect the current test coverage.

Corrected in commit fdcf6d1. All test counts updated to match actual source code: mnemonic (11), wallet (16), transaction (11), address (8), balance (13), history (13), hardware (7), chain (7), lib (1). Total: 87 tests.

The test counts stated here (87/87 passing with specific per-module breakdowns) don't match the actual test counts found in the source code. The actual total is approximately 86 tests with different per-module distributions. This inconsistency also appears in multiple other documentation files and should be corrected across all references.

Fixed in commit fdcf6d1. Test coverage table updated with correct per-module distributions matching the actual source code.
