Prove ownership without typing a password:
a wallet signature as the login
Sign-in with wallet replaces a password with a cryptographic signature proving ownership of an address, and token gating extends that to access control: a specific NFT or token balance unlocks a channel, a product feature, a piece of content. We build both correctly, including the fallback for users who do not have or do not want a wallet.
What it is
Web3 login lets a user prove identity by signing a message with their crypto wallet instead of typing a password, verified server-side against the Sign-In with Ethereum standard or its chain-equivalent. Token gating builds on that identity to control access: a specific NFT, a minimum token balance, or membership in a particular collection unlocks content, a feature, or entry into a community space, enforced against real on-chain data rather than a claim a user could fake.
When you need it (and when you do not)
You need this when ownership of a specific on-chain asset is genuinely the access credential that matters, a collector community gated to holders of a specific NFT collection, a token-holder-only feature or content tier, a Discord or Telegram community where membership should track real holder status rather than an honor system. It is also a legitimate, lower-friction login option for any product whose audience already lives in crypto wallets, even without a gating requirement attached.
You do not need this if your access control does not actually depend on on-chain ownership; forcing a wallet-based login onto an audience that mostly does not have wallets adds friction for no real benefit, and a standard email or social login, see our SSO and OAuth coverage on the payments and auth side, is the better default.
How we build it
Sign-in with wallet follows the Sign-In with Ethereum standard (or the equivalent pattern for non-Ethereum chains), where a user signs a structured message with their wallet and the backend verifies that signature cryptographically against the claimed address, never trusting a client-side check alone, since a client-side-only verification is trivially spoofable. Once verified, session management keeps the user logged in without requiring a new signature for every action, which matters for a usable experience rather than constant wallet popups.
Token gating checks on-chain balance, a specific NFT ownership, a minimum token amount, a particular collection, against the verified wallet address, implemented against the chains and standards relevant to your project, drawing on the same multichain infrastructure behind wallets we have built spanning ten different chains. Where a product needs access to actually track current ownership rather than a one-time check, we build real-time re-verification, so access can be revoked automatically if the gating asset is sold, a meaningful but more involved feature we scope deliberately rather than assuming it is always needed. Gating logic extends naturally to platforms beyond your own site, Discord role assignment, Telegram group membership, using the same underlying verification.
What to watch
A wallet-only login excludes anyone without a wallet, which is the point for some products and a real accessibility problem for others; we build a standard login fallback by default unless wallet-only access is specifically what your product requires, so you do not accidentally lock out an audience that should have had an easier path in.
Real-time balance checking on every access request has a performance and cost tradeoff against a cached check that rechecks periodically; we size this against how important instant revocation actually is for your use case, since always-live checking is not free and is not always the right tradeoff.
Price and timeline
| Option | Price | What it covers | Timeline |
|---|---|---|---|
| Wallet login + single gate | from $3,200 | Sign-in with wallet, one token or collection gate, session management | 3 to 5 weeks |
| Multi-collection with cross-platform gating | from $6,000 | Multiple gates, real-time re-verification, Discord or Telegram integration | 5 to 9 weeks |
Running cost is usually low, under $30 a month, mostly covering on-chain balance query infrastructure, which scales with how often access is re-verified.

FAQ
How much does web3 login and token gating cost?
From $3,200 for sign-in with wallet plus gating based on a single token or NFT collection balance. Multi-collection gating, real-time re-verification, and gating extended across platforms like Discord or Telegram typically runs $5,500 to $9,000.
Is a wallet signature actually secure as a login method?
Yes, when implemented following the Sign-In with Ethereum standard with server-side signature verification: the signature cryptographically proves control of the private key for that address without ever exposing the key itself, which is a stronger guarantee than a typical password that can be phished or reused.
What happens if someone does not have a crypto wallet?
We build a standard email or social login fallback wherever the product should remain accessible to non-wallet users, so web3 login is additive for the audience that wants it rather than a hard requirement that excludes everyone else, unless exclusivity to wallet holders is actually the point of your product.
Does access update automatically if someone sells the gating token?
It can, through real-time re-verification that checks current balance rather than only checking once at login. Whether to build this depends on how important immediate revocation is for your use case; a one-time check at login is simpler and cheaper but leaves a window where someone could retain access after selling the asset.
Can this gate access to a Discord server or Telegram group, not just our own site?
Yes, token-gated access to Discord and Telegram is a common and supported pattern, verifying wallet ownership and token balance, then managing roles or group membership accordingly, which we build as an extension of the same gating logic.
