Adwait Keshari

I'm Adwait, a full-stack engineer from Bhopal, India, studying Data Science at IIT Madras. I take hard primitives (cryptography, on-chain storage, AI agents) and turn them into products people actually use. Recent work: - Ferry: one AI memory you own, carried across ChatGPT, Claude and Gemini. Stored on Walrus Memory Mainnet, owned by a Sui wallet, every chain read through Tatum's Sui gRPC, and agents pay for memory over HTTP 402 with USDC on Sui. Built solo for Tatum x Walrus Total Recall. - KIRCHHOFF: won the TOKEN2049 Singapore Origins Main Track. A cross-chain verifier built on Chainlink CRE and CCIP 2.0 that refuses to sign any transfer when a token's money stops adding up across chains. - StellaRay: sign in with Google, get a Stellar wallet. No seed phrase; zero-knowledge proofs keep your identity off chain. - Prophit: one sentence of conviction becomes an autonomous agent trading prediction markets on Solana. - Voxa: a voice agent for macOS with 126 tools and a five-provider LLM router with failover. - Tempo Books (stablecoin payroll accounting), Melodex (creative IP on Story Protocol) and Meridian (ZK-KYC RWA vaults on Mantle, built at the OnchAIn Island hacker house). I organize ETH Builders Day Bhopal and lead the Bhopal DAO community. I ship end to end: contracts, backend and a frontend that feels finished, with strict TypeScript, tests and security review by default. Open to freelance work, founding-engineer roles and hackathon teams.

  • Ferry: one AI memory you own preview
    Ferry: one AI memory you own

    Ferry rescues what ChatGPT, Claude and Gemini know about you, stores it on Walrus Memory Mainnet under your Sui wallet, and offers the right facts in whichever AI you open next, each with a receipt showing where it came from. Every chain read goes through Tatum's Sui gRPC gateway, and agents can pay 0.01 USDC on Sui over HTTP 402 for a slice of memory you choose to share. Chrome extension, Next.js app, payment gateway and SDK, built solo. Live at ferry-memory.vercel.app

  • KIRCHHOFF: TOKEN2049 Singapore winner preview
    KIRCHHOFF: TOKEN2049 Singapore winner

    Winner of the TOKEN2049 Singapore Origins Main Track. A bridge can verify that a message was signed without verifying that the value behind it adds up. KIRCHHOFF is a cross-chain verifier for Chainlink CCIP 2.0, built on Chainlink CRE, that refuses to sign any transfer when a token's supply stops adding up across chains.
