Walkthrough

The GetBlobByVersionedHashAndBlockTime method in BeaconNodeClient was updated to construct HTTP requests explicitly using http.NewRequestWithContext and execute them with c.client.Do, replacing the previous direct use of c.client.Get. Error handling was refined to address request creation and execution separately. Additionally, the patch version constant VersionPatch was incremented from 74 to 75 in params/version.go.

Changes

Cohort / File(s)	Change Summary
HTTP Request Refactor rollup/da_syncer/blob_client/beacon_node_client.go	Refactored HTTP GET logic in GetBlobByVersionedHashAndBlockTime to use explicit request creation and execution; improved error handling for request creation and execution steps.
Version Bump params/version.go	Incremented patch version constant VersionPatch from 74 to 75 without other code or logic changes.

Poem

In the code where blobs and hashes meet,
A rabbit hopped with nimble feet.
Requests now crafted, context in tow,
Errors caught before they grow.
With careful paws and whiskers keen,
The syncer’s path is clear and clean! 🐇✨
