Bounty: Create Offline Signing Cucumber Test

Tier: M — 60,000 XTM

Description

The cucumber testing suite has unit tests for offline signing but lacks a complete integration test covering the full gRPC flow. Write a cucumber test that creates a view-only wallet, initiates an offline signing process via gRPC, signs the transaction using a full-spend wallet, broadcasts via the view-only wallet, and verifies the receiving wallet confirms the funds.

Acceptance Criteria

• A cucumber test creates a view-only wallet and starts an offline signing process via gRPC
• The transaction details are signed using a full-spend wallet
• The signed transaction is broadcast via the view-only wallet
• The receiving wallet has the funds confirmed for the test to pass

Context

• Issue opened by @SWvheerden
• Existing offline signing unit tests: base_layer/wallet/tests/ (search for offline / one_sided)
• gRPC service definitions: applications/minotari_app_grpc/proto/wallet.proto
• Existing cucumber step definitions: integration_tests/tests/steps/wallet_steps.rs
• Relevant code: cucumber test suite in integration_tests/

Original issue description (preserved before bounty rewrite)

Description

We have the cucumber testing suite, but we need to add offline signing tests. We have unit tests covering offline signing, but we don't have a complete integration test where a wallet runs through the entire gRPC flow.

Acceptance criteria

• Create a test where we create a view-only wallet that, via gRPC, starts an offline signing process
• Sign the transaction details using a full-spend wallet
• Broadcast the transaction via the view-only wallet
• The receiving wallet should have the funds confirmed for the test to pass
