A full-stack platform for fractional ownership of private equity investments, built on Base network with SEC Regulation A+ compliance.

FractionalPE enables retail investors to access high-grade PE seed rounds through tokenized SPV ownership. The platform enforces transfer restrictions via whitelist-based compliance, ensuring only KYC/AML-verified investors can hold tokens.
