📝 Walkthrough

Walkthrough

This pull request removes the staking-oracle service from the repository's build and deployment infrastructure by deleting oracle module references from the root Makefile, removing oracle from EKS deployment targets, and updating build pipelines to depend on tx-submitter and token-price-oracle instead.

Changes

Oracle Service Build Infrastructure Removal

Layer / File(s)	Summary
Root Makefile oracle module removal Makefile	Oracle module is removed from update_all_mod target and replaced with tx-submitter and token-price-oracle module updates. Oracle module go mod tidy is removed from fmt-go target, replaced with tx-submitter tidy.
EKS Makefile staking-oracle targets removal MakefileEks.mk	Staking-oracle build and start targets for both mainnet and qanet environments are removed from EKS Makefile. Minor formatting adjustment to unrelated gas-price-oracle-hoodi target.

• morph-l2/morph#816: Both PRs modify the CI workflow definition for the oracle at .github/workflows/oracle.yml (this PR removes it, the other PR comments/disables it), so they overlap at the workflow level.

Poem

🐰 The oracle hops away with grace,
Its Makefile targets erased,
Build lines now trimmed and clean,
A leaner codebase, serene!
