📝 Walkthrough

Walkthrough

This pull request introduces custom error types in the Chainvoice contract to replace string-based revert messages, updates corresponding test assertions, and enables Citrea Testnet support across the frontend application by adding chain configuration entries and UI icons.

Changes

Cohort / File(s)	Summary
Contract Error Handling contracts/src/Chainvoice.sol	Introduced 20 custom error declarations (Unauthorized, Reentrancy, ZeroAddress, etc.) replacing string-based require/revert messages throughout invoice creation, payment, cancellation, and withdrawal functions.
Contract Tests contracts/test/Chainvoice.t.sol	Updated test expectations to use selector-based reverts (e.g., Chainvoice.NotAuthorizedPayer.selector) instead of string message matching for error assertions.
Frontend Chain Configuration frontend/src/utils/chainConfig.js, frontend/src/page/CreateInvoice.jsx	Added Citrea Testnet to exported chain configuration and mapped its chain ID (5115) to public RPC endpoint.
Frontend UI Integration frontend/src/App.jsx, frontend/src/components/NetworkSwitcher.jsx	Appended citreaTestnet to AllChains array, imported BatchPayment module, added Bitcoin icon (orange) for Citrea Testnet in network switcher component.

Poem

🐰✨ Custom errors now declare with pride,
No more strings to hide and confide,
Citrea joins the chain of friends,
With Bitcoin icons and RPC ends,
The contract speaks in types so bright! 🌟

❌ Failed checks (3 warnings, 1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The PR title describes automatic network detection from wallet, but changes include contract error refactoring unrelated to network selection.	Consider revising the title to reflect both major changes (e.g., 'Refactor contracts with custom errors and auto-detect wallet network') or split into separate PRs.
Out of Scope Changes check	⚠️ Warning	Contract error refactoring (20 new custom errors replacing string messages) appears unrelated to network selection feature requested in issue #53.	Remove contract error changes from this PR or update linked issue to explicitly include error refactoring as a requirement.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Linked Issues check	❓ Inconclusive	The PR addresses issue #53's requirement to auto-select user's wallet network, and includes Citrea Testnet configuration, but also contains unrelated contract error refactoring.	Confirm whether contract error refactoring is required by issue #53 or should be split into a separate PR. Verify all commits are intentional.
