# Core Web

[Core Web](https://core.app) 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](/docs/core-web/portfolio).

**It's the policy surface for agents.** The
[Core MCP Server](/docs/mcp/overview)'s permissions — accounts, networks,
spend limits, recipients — are configured and signed in Core Web's
[AI connectors settings](/docs/core-web/ai-connectors).

**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.

Testnet mode (Settings → Advanced) switches every network to its test
variant — useful for exercising anything on this list against Fuji before
mainnet.
