Conversation
Wires 0G (16661/0x4115) into the general chain-ID lookup maps (NETWORK_TO_NAME_MAP, CHAIN_ID_TO_CURRENCY_SYMBOL_MAP, CHAIN_ID_TO_NETWORK_IMAGE_URL_MAP, CHAIN_ID_TOKEN_IMAGE_MAP) -- not the FEATURED_RPCS/additional-network picker list, which stays out of scope per the standing additional-network-is-optional ruling (same treatment as Somnia). Native currency 0G reuses the network icon (no separate native-token asset), copied from this enablement's official branding assets. Core package bump (@metamask/assets-controllers) deferred to a follow-up commit once MetaMask/core#9760 merges and publishes.

The previous commit pointed CHAIN_ID_TOKEN_IMAGE_MAP.ZERO_G at ZERO_G_IMAGE_URL (the purple-background network logo), reasoning "0G has no separate native-token asset" -- that was wrong. chain-input.yaml tracks two distinct assets: branding.networkLogoSvgPath (purple background, white mark -- the network icon) and nativeToken.logoSvgPath (white background, purple mark -- the native-token icon). Same brand mark, inverted colors, genuinely different files (confirmed via checksum, not just visual inspection). Adds app/images/0g-native.svg (from the enablement's own branding/native/0g.svg) and ZERO_G_NATIVE_TOKEN_IMAGE_URL, and repoints CHAIN_ID_TOKEN_IMAGE_MAP.ZERO_G at it. CHAIN_ID_TO_NETWORK_IMAGE_URL_MAP.ZERO_G (the network map) is unaffected and stays on the purple network logo.

Overview
Adds 0G (16661 /
0x4115) to the extension’s shared network metadata so the UI can show the correct name, ticker, and artwork when that chain is in use (e.g. custom or dapp-added networks).New branding SVGs (
0g.svg,0g-native.svg) and constants wire 0G intoCHAIN_IDS, display name 0G, native currency0G, and the usual maps:NETWORK_TO_NAME_MAP,CHAIN_ID_TO_CURRENCY_SYMBOL_MAP,CHAIN_ID_TO_NETWORK_IMAGE_URL_MAP, andCHAIN_ID_TOKEN_IMAGE_MAP.Out of scope: no entry in
FEATURED_RPCS/ the additional-network picker (same pattern as Somnia).Reviewed by Cursor Bugbot for commit 75f6253. Bugbot is set up for automated code reviews on this repo. Configure here.
