Core Web
Core Web is the browser version of Core — a full wallet that runs at a URL, with no installation. For developers, it matters in three ways.
It's where Core users act on your protocol. Swaps, staking, lending, and NFT views execute from Core Web against public contracts. If your protocol is integrated there, Core users interact with it without ever visiting your site — and if it isn't, users still see positions your contracts create in their portfolio.
It's the policy surface for agents. The Core MCP Server's permissions — accounts, networks, spend limits, recipients — are configured and signed in Core Web's AI connectors settings.
It's a signing surface like the others. Core Web signs with seed-phrase accounts, seedless (social-login) accounts, Core Extension, or hardware wallets, and the same approval pipeline — including Blockaid screening — applies as everywhere else.
