Summary
Adds Arc mainnet (chain 5042) to
@0xsequence/network. Arc Testnet (5042002) was added in #901, but the mainnet chain has no entry, sonetworks[5042]isundefined— consumers get no chain title, logo or block explorer URL for Arc.ChainId.ARC = 5042networks[ChainId.ARC]— title "Arc", explorerhttps://arc.etherscan.io/, native token USDC (18 decimals), matching the Arc Testnet entry's shapecreateNetworkConfig(ChainId.ARC)inallNetworksNative currency and explorer match the Arc chain definition the Trails SDK ships (
0xtrails0.18.6).Why now
0xtrails0.18.6 added Arc support, and trails-app consumes both packages. Without this entry, every Arc transaction in that app renders with a blank chain name and no explorer link, so the app currently carries a local shim of thenetworksmap that can be deleted once this lands and releases.Verification
