I'm Victor, 18 years old, solo founder. I've spent the last several months building TxDesk, an AI-powered support widget that DeFi protocols can embed on their sites. Users paste a transaction hash or wallet address, and the agent decodes it into plain English.

What it actually does

The agent pulls live on-chain data across 46 blockchains (21 EVM chains + Solana + Bitcoin + TRON + XRP + 20 more). It can:

Decode any transaction and explain what happened in plain language

Scan token approvals and flag risky unlimited allowances

Check wallet balances across any supported chain

Diagnose why a transaction failed

Track cross-chain bridge transfers

Assess smart contract risk

Verify wallet ownership via WalletConnect (Sign-In With Ethereum / Solana)

It deploys as an embeddable website widget (one script tag), a Discord bot, or a Telegram bot.

The stack

TypeScript monorepo (api + widget + website + shared package)

Preact for the widget (needs to be tiny, it loads on other people's sites)
