Explanation
The current default block explorer for Sei Mainnet (
seitrace.com) is beingdecommissioned. This PR updates the
BlockExplorerUrlentry forBuiltInNetworkName.SeiMainnetto its replacement,seiscan.io.seiscan.iois an Etherscan-family explorer. This is a UI-URL change only —@metamask/controller-utilsexposes the user-facing block-explorer URL (theone consumers concatenate
/tx/<hash>or/address/<addr>onto), and thehostname swap is the only thing that needs to land here.
Clients (metamask-extension, metamask-mobile) will pick this up via a
@metamask/controller-utilsbump and ship a state migration to rewriteexisting users' stored Sei explorer URL.
