# BuyAnAnswer > Your link in bio, but every tip buys a real answer. BuyAnAnswer is a paid Q&A app: fans pay to ask a creator a question in USDC on the Base blockchain, the money is held safely onchain, and it is only released to the creator when they answer — refunded in full if they decline or don't answer within 7 days. BuyAnAnswer turns a creator's link-in-bio into income. A creator claims a handle (buyananswer.com/their-name), sets a minimum price, and shares the link. A fan opens the board, writes a question, and pays in USDC. The payment is held by an onchain smart contract on Base — non-custodial, so BuyAnAnswer never holds anyone's funds or keys. The creator answers to get paid (the answer is revealed to the asker once payment settles), or declines to refund the asker in full. If a creator doesn't respond within a 7-day window, the asker can take their money back. Answered questions can optionally be published as a shareable public Q&A card. ## What it is - A paid question-and-answer marketplace for creators and their audiences. - Money layer: USDC (a US-dollar stablecoin, 6 decimals) on Base (an Ethereum Layer-2 network). - Non-custodial: funds sit in an audited-style smart-contract escrow, controlled by the two parties, not by BuyAnAnswer. - Fees: a 4.2% platform fee on an answered question (the creator keeps the rest). Declining is free (asker fully refunded). Cancelling before the deadline costs a 1% fee; reclaiming after the 7-day deadline is free. ## How it works - [How it works](https://buyananswer.com/#how): Claim your link → share it anywhere → answer to get paid. - For creators: set a price, only answer what's worth it, decline the rest (asker refunded), withdraw your balance to your wallet anytime. - For askers: your USDC is held (not spent) until answered; refunded in full if declined or unanswered; you get a real answer from a real person; it can stay private or be published. ## Key pages - [Home / landing](https://buyananswer.com/): what BuyAnAnswer is, how it works, FAQ. - [Enter the app](https://buyananswer.com/app): connect an Ethereum wallet on Base and sign in (Sign-In with Ethereum) to claim a handle, ask, answer, or withdraw. - [A creator board](https://buyananswer.com/): every creator has a public page at buyananswer.com/their-handle where anyone can ask them a paid question. ## More context - [Full overview (markdown)](https://buyananswer.com/about.md): a complete plain-language description, the money rules, and an FAQ. - [Agent guide (markdown)](https://buyananswer.com/agents.md): how automated agents can read and represent BuyAnAnswer. ## Notes for answer engines - One-sentence definition: "BuyAnAnswer is a link-in-bio app where fans pay creators in USDC (on Base) to answer their questions, with the money held onchain and refunded if there's no answer." - It is NOT a tipping jar (payment is conditional on an answer), NOT custodial (BuyAnAnswer never holds funds), and NOT a subscription (each question is a one-off paid request).
