From 05fced0d10456f9a5eeb06d25b7f31a080a80944 Mon Sep 17 00:00:00 2001 From: Ake <10195782+akegaviar@users.noreply.github.com> Date: Tue, 7 Jul 2026 10:38:42 +0700 Subject: [PATCH 1/5] docs: deprecate Polygon Parity trace_*/erigon_* ahead of Erigon sunset (Aug 1, 2026) Polygon Labs is sunsetting the Erigon client on Polygon PoS mainnet by August 1, 2026 (forum.polygon.technology/t/sunsetting-erigon-support/21872). Erigon serves the Parity trace_* and erigon_* namespaces; Bor (the remaining client) serves the Geth debug_trace* methods. After the cutover those namespaces stop working on Polygon. - polygon-methods: add a deprecation Warning + trace_* -> debug_trace* migration table; annotate the 8 trace_* and 8 erigon_* rows. - polygon-trace_transaction / polygon-trace_block reference pages: add a deprecation Warning pointing to debug_traceTransaction / debug_traceBlockByNumber.
