Sign in with a wallet. Or three.
Most platforms make a user pick one wallet. Real users have several: a hot wallet for daily activity, a hardware wallet for storage, a separate one for an old NFT account they still use. Forcing them to consolidate is bad UX; ignoring the rest is bad data.
Synq treats every wallet a user links as part of the same identity. Your app sees the full footprint, drives smarter eligibility and rewards, and never makes the user reconnect. Sign-in is a signed message, never a transaction.
A real wallet footprint, not a single-address snapshot.
Synq's wallet model is built for users with multiple wallets and apps that want a complete picture of activity, not a partial one.
Solana wallet sign-in, first-class
Sign-in via wallet signature is a peer to social and email auth, not a separate flow. Phantom, Solflare, Backpack, and any wallet adapter that signs Solana messages work out of the box.
Multi-wallet by default
Users link as many wallets as they want to one Synq profile. Your app sees the full footprint, instead of a single-address snapshot, which means smarter eligibility, rewards, and personalization.
Message signing only
Linking a wallet never requires a transaction or moving funds. The signature proves ownership, grants no permissions, and never exposes private keys. Synq can verify ownership without ever being able to move assets.
One profile across products
A user who connected three wallets to your app last year still has those three wallets when they show up at your sister product. Identity is the constant; the products are the variable.
Token gates without rebuilding
Gate features by SPL holdings (or NFT collections) using the same Synq token surface. The user signs in once, the gate evaluates against their full multi-wallet view.
Bridges to social and email
Wallet users can link a social or email later for recovery. Social users can link a wallet later to unlock token-gated features. Identity travels in both directions.
Wallet linking is a signature, never a transaction.
Adding a wallet to a Synq profile uses a signed message proving control of the address. No transaction is ever broadcast, no SOL is ever moved, no permissions are ever granted. The signature confirms ownership and nothing more.
This is the same primitive Sign in with Solana uses, wrapped in a hosted flow with replay protection, nonce verification, and per-brand audience binding so a wallet linked to Brand A cannot be replayed against Brand B.
- Signed-message ownership proof, never a transaction
- Nonce + replay protection per request
- Audience-bound to the brand the user authenticated against
- No private keys, no signing approvals, no on-chain footprint
Wallet sign-in for crypto-native users.
And for the millions of users who came in via social and want to link a wallet later.
