FAQ
Questions worth answering up front
What counts as a "whale alert"?
Any decoded on-chain move on a wallet you watch: ERC-20 transfers, swaps on major DEXes (Uniswap v3 at launch), large ETH transfers, withdrawals from exchanges. We filter noise (dust transfers, failed txs) and only summarise events with material USD value.
Which chains are supported?
Ethereum mainnet and Base at launch. Architecture is multi-chain by design (CAIP-2 identifiers everywhere), so Solana, Arbitrum, Optimism, and others are on the post-launch roadmap.
What happens to my wallet's privacy?
We use Sign-In With Ethereum (EIP-4361) — you sign a one-time message to prove ownership, we never see your private key and never request transaction-signing capability. The wallet you connect is only used as your account identifier; addresses you watch are public on-chain data anyway.
Can I cancel anytime?
Yes. Manage your subscription from /app/billing — it opens the Polar billing portal where you can cancel, update card, or change plan. No commitments, no cancel fees. Your Pro features stay active until the end of the billing period.
What's the ZK proof-of-balance thing on the roadmap?
Post-launch feature: instead of paying $19/mo, you'd be able to unlock Pro by proving (with a zero-knowledge proof) that a wallet you control holds a threshold amount of a specific token — without revealing the wallet or the exact balance. Built on Noir. Stretch goal for the post-MVP sprint.
