Hi @towanTG @0xepicode @ice-chillios,

Following up on this PR for Cheese Blockchain (NCH) EVM integration:

• Added a changeset file (.changeset/add-cheese-blockchain.md) for @swapkit/types, @swapkit/helpers, and @swapkit/toolboxes.
• Normalized chainIdHex to lowercase (0x4f1a) in packages/types/src/chains/evm.ts to match all other EVM configs.

Note regarding the build-lint-test check failure:
The current pull_request_target configuration in .github/workflows/pr-test.yml uses actions/checkout@v4 with ref: ${{ github.head_ref }} without specifying the fork repository (repository: ${{ github.event.pull_request.head.repo.full_name }}). This causes Git to search for the branch in origin (swapkit/SwapKit) instead of the fork, which fails across all fork PRs after 7 seconds with branch could not be found.

All files have been verified against SwapKit's EVM architecture. Whenever you have a chance, could you please review the PR and approve the workflow run?

Thank you!

Hi @cryptoexdevcheese, at this stage, we only integrate chains that are requested by integrators and have sufficient demand, besides that a chain need to have liquidity on one of our liquidity partners.

Thank you for your contribution!
