EXECUTIVE SUMMARY

fndr is a decentralized fundraising protocol for tokenized startup equity, designed to fix a core inefficiency in early-stage finance:

Capital sits idle while innovation waits.

Instead of locking funds in dormant wallets, fndr deploys raised capital into ERC-4626 yield vaults, allowing founders and investors to earn yield before an exit.

The protocol combines:

• ERC-1400 compliant equity tokens

• On-chain yield generation

• Privacy-preserving onboarding via zkPassport

• AI-powered investment and portfolio insights

• Secondary-market liquidity for startup shares

Track Alignment

• Arbitrum Open Track – Creating the Innovation product through Arbitrum ecosystem

Status
✅ Core contracts deployed
✅ Secondary market live
✅ AI insights integrated
✅ zkPassport identity verification functional
