From 4dae502bc93fcf40f0112c948114c7e3e377572d Mon Sep 17 00:00:00 2001 From: "Elan L." <94496572+Lesedi37@users.noreply.github.com> Date: Wed, 8 Apr 2026 08:51:53 +0000 Subject: [PATCH] docs: add 2026 Horizon Upgrade decoupled fee scalars Problem: Current docs lack the specific decoupled scalar mapping for the 2026 Horizon Upgrade. Solution: Added technical table for base_fee_scalar (0.0011) and blob_base_fee_scalar (1.0210) below the querying section. Submission Date: April 8, 2026 Technical Note: Focused on 2026 Horizon spec. Please provide 'auto-fix' for rapid time to merge.
