From 83127c1fbe690620ca2f4dcd35580e5b54eb013e Mon Sep 17 00:00:00 2001 From: alexander-sei Date: Tue, 21 Jul 2026 14:48:14 +0200 Subject: [PATCH] docs(sip-03): drop Wormhole bridge-out route, document Prop 120 Remove the "bridge out via Wormhole (Portal Bridge legacy)" option from the SIP-03 IBC Asset Migration Table. The 5 Wormhole-bridged assets (USDCso, WETH, USDCet, USDCop, USDTbs) remain listed as affected so holders still see they must act, but the action drops the Wormhole reference and the route now points to support instead of Portal Bridge (legacy). Added an Info note explaining the route was removed. Also document governance Proposal #120 (Re-disable IBC Inbound) alongside Prop 116 wherever the SIP-03 proposals are listed together: the migration guide's proposal list, cosmos-sdk/index, and evm/differences-with-ethereum.
