The JavaScript SDK for Varial, SDF's non-custodial Stellar wallet, which was called Freighter until its rename. A dapp can request the user's public key, read the active network, and hand off transactions, Soroban authorization entries and messages for signing, on desktop through the browser extension and on mobile over WalletConnect v2. Free and Apache-2.0. It only talks to Varial; SDF's own docs point to Stellar Wallets Kit if you want to support several Stellar wallets. Existing @stellar/freighter-api integrations keep working, while new ones should use @stellar/varial-sdk.

Catch Connects one wallet only; use Stellar Wallets Kit for several
