Today’s fiat-crypto onramps are broken: they require centralized custodians, invasive KYC, high fees, and slow settlement times. </p> <p>Beanstick solves this by replacing middlemen with a decentralized network of autonomous Liquidity Provider (LP) agents. These agents compete to offer the best exchange rate in millisecond-level reverse auctions. When a user locks their fiat payment, smart contracts secure the corresponding cryptocurrency in escrow. Verification of the fiat transfer is handled cryptographically using <strong>zkTLS</strong>—verifying bank-receipt TLS sessions without ever exposing sensitive credentials. Once verified, the escrow releases funds to the user automatically. </p> <p>No operators. No custodians. No centralized exchanges. Just trustless, peer-to-agent settlement.</p> <p><em>Or run it locally to see the full AI swarm in action:</em></p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> bash git clone https://github.com/harshh1505/beanstick.git cd beanstick pnpm install ./start-all.sh </code></pre> </div> devchallenge weekendchallenge
