Introduction
StarKey Wallet is a self-custodial, multi-chain crypto wallet for managing digital assets and accessing decentralized applications across Supra , Aptos , Ethereum , and more — one wallet, every chain you actually use.
Download StarKey
Pick the platform you want to start with. The browser extension is the fastest way to connect to web dApps; the mobile apps keep your accounts and tokens in your pocket.
StarKey is self-custodial — your keys and seed phrase live on your device, never on our servers. Back them up before funding the wallet.
What you get
- Multi-chain by default — manage Supra, Aptos, Ethereum, and more from a single account list, no app switching.
- Tokens, NFTs, swaps, and bridges — send, receive, swap on-chain, and bridge across networks from the same UI.
- Buy crypto with fiat — on-ramp directly inside the app via an integrated provider.
- dApp connect — the extension injects a
starkeyprovider so any web app can request signatures and transactions with your permission.
For developers
StarKey exposes its provider on both web (browser extension) and iOS / Android (mobile dApp browser). On web, the extension injects a starkey object into the JavaScript context of every site the user visits — your dApp talks to it the same way it would any wallet provider, and the user explicitly approves every signature, transaction, or connection request.
