In the fast-paced world of blockchain, staying ahead means embracing tools that make development smoother and more secure. Yesterday, Supabase dropped a game-changing announcement on X (formerly Twitter) that's got the Web3 community buzzing. They're rolling out support for Web3 logins using Ethereum and Solana wallets. If you're into meme tokens or building crypto apps, this could be a big win for you.
What the Tweet Said
The main post from @supabase simply stated: "Today we're announcing support for Web3 logins using @ethereum and @solana #SupabaseSelect." Accompanied by a sleek image featuring the logos of what looks like a lightning bolt (perhaps nodding to speed), Solana, and Ethereum, it set the tone for this exciting update.
They followed up with a link to their blog post and an invite to watch more announcements at select.supabase.com. The thread sparked reactions from developers and crypto enthusiasts, with comments ranging from excitement to suggestions for adding more chains like Kaspa.
Diving into the Details
Supabase, known as the open-source alternative to Firebase but built on Postgres, is making it easier to integrate wallet-based authentication. This new feature leverages the Sign in with Ethereum (SIWE) standard, outlined in EIP-4361. It's an off-chain method where users sign a message with their wallet to log in, without needing to send a transaction on the blockchain. The cool part? It works seamlessly for both Ethereum and Solana, thanks to compatible wallet standards.
For those new to this, SIWE presents a structured message like this:
example.com wants you to sign in with your Ethereum account:
0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2
I accept the ExampleOrg Terms of Service: https://example.com/tos
URI: https://example.com/login
Version: 1
Chain ID: 1
Nonce: 32891756
Issued At: 2021-09-30T16:25:24Z
Resources:
Your wallet app shows a confirmation dialog, and once signed, Supabase verifies it and grants a session. No more juggling usernames and passwords—pure crypto magic.
How to Get Started
Enabling this is straightforward. In your Supabase project, head to the dashboard or use the CLI to tweak your config:
[auth.web3.solana]
enabled = true
[auth.web3.ethereum]
enabled = true
For security, add rate limits and CAPTCHA:
[auth.rate_limit]
web3 = 30 # Logins per 5-minute interval per IP
[auth.captcha]
enabled = true
provider = "hcaptcha"
secret = "your-secret-here"
On the frontend, the JavaScript SDK makes it a breeze:
await supabase.auth.signInWithWeb3({
chain: 'ethereum', // or 'solana'
statement: 'I <3 Supabase!',
})
It supports popular wallet adapters, like Solana's Wallet Adapter or Ethereum's discovery mechanisms used in MetaMask.
Why This Matters for Meme Tokens
Meme tokens thrive on community and virality, often on Solana for its speed and low fees, or Ethereum for its established ecosystem. With Supabase's Web3 logins, developers can create token-gated experiences—think exclusive chats for holders of your favorite dog-themed coin or NFT drops tied to wallet verification. It's perfect for DAOs, DeFi dashboards, or even meme marketplaces where security is key.
Imagine building a meme token app where users log in with their Solana wallet, verify ownership of a specific token, and unlock premium features. No more fake accounts or bot spam; everything's tied to real blockchain identities. This lowers barriers for creators in the meme space, letting them focus on fun and innovation rather than backend headaches.
The feature stemmed from community demand, including a bounty with the Solana Foundation. Shoutout to contributor Omar (aka Bewinxed) for spearheading the Solana side since 2021.
Looking Ahead
Supabase isn't stopping here. They're hinting at more Web3 integrations, and with their focus on scalability and security, this could reshape how we build decentralized apps. If you're a blockchain practitioner eyeing meme tokens, dive into the docs and start experimenting.
