Metanet Client is the desktop wallet for using Metanet apps with your identity, permissions and BSV. Use it alongside your web browser on macOS, Windows or Linux. On a phone or tablet, use [Metanet Explorer](https://docs.projectbabbage.com/docs/metanet-explorer), which combines the browser and wallet.

## Identity keys and addresses

Metanet apps normally identify recipients with an **identity key**. This is a public key, not an exchange deposit or withdrawal address. A traditional **type-1 BSV address** is a different representation used by many exchanges and older wallets. Do not paste an identity key into an exchange's address field.

[Mountaintops](https://mountaintops.net/) lets your connected Metanet wallet derive a traditional BSV address and then import funds sent there. The [funding walkthrough](https://docs.projectbabbage.com/docs/metanet-client/funding) covers the complete process, including the import step and its public-address privacy tradeoff.

## For builders

Use the BRC-100 interface through `WalletClient` from `@bsv/sdk`. The same application API can connect through the desktop bridge or Explorer's in-app browser. Users still approve sensitive requests in their wallet. Start with [a connection check that does not move funds](https://docs.projectbabbage.com/docs/metanet-client/developers), then follow the shared [wallet guides](https://docs.projectbabbage.com/docs/guides/wallet).

Older tutorials referring to `@babbage/metanet-client`, the original Metanet client or a browser extension describe other generations of the stack. For new integrations, follow these guides and the maintained [TypeScript stack](https://github.com/bsv-blockchain/ts-stack). An old recovery file or account is not automatically compatible with every newer wallet; preserve it and follow [migration guidance](https://docs.projectbabbage.com/docs/metanet-client/backup-and-recovery).
