Solana Wallet Standard
One adapter per installed Solana wallet — Phantom, Solflare, Backpack and more.
The Wallet Standard is the headless interface Solana browser wallets implement to announce themselves to dapps. It's the same layer @solana/wallet-adapter is built on, with no wallet SDK to bundle.
Pollar's adapter wraps each discovered wallet as a WalletAdapter with chain SOLANA, so the SDK logs in with SIWS (Sign In With Solana) instead of Stellar's SEP-10, and signs Solana transactions through the wallet.
Stellar and Solana wallets live in the same walletAdapters list: one login modal, one button per chain. See the Setup tab for @pollar/core and @pollar/react.
Why Pollar, not just the Wallet Standard?
The Wallet Standard finds the wallet. Pollar turns that wallet into a signed-in user with a backend behind them.
Sign-in, not just connect
Pollar issues the SIWS challenge, verifies the signature server-side and hands you a session — no auth server of your own.
Two chains, one modal
Solana wallets sit next to Stellar wallets, Privy email login and more behind the same login flow.
Payments built in
Send SOL and SPL tokens with app-sponsored fees, and token accounts created for the recipient.
Ramps to Solana
Fiat on/off-ramps settle straight to the user's Solana wallet, on Pollar's API.
The Wallet Standard finds the wallet. Pollar ships the app.
