Technical Briefings
Federico Pomi & Daniel Rollingher
Federico, CEO and co-founder of Fabrica, presents Fabrica — a platform that makes real estate programmable by wrapping each property in a legal trust whose ownership is represented by a non-fungible token. The demo walks through a complete on-chain land transaction on the Fabrica platform: a buyer picks a plot, clears KYC, links a Plaid-connected Chase checking account, signs a transfer agreement, and the NFT plus bank transfer settle together in about three minutes — with a recorded county deed and land-tax-assessor appointment falling out of the same flow. Because Fabrica uses a standard NFT contract, each property shows up on OpenSea with full transaction history, priced in Sila USD. Federico closes with the broader vision — collateralize, borrow against, fractionalize, or earn DeFi-vault yield on real property — and Fabrica's state-by-state expansion in California, Arizona, New Mexico, and Colorado.
Kyle Tut & Justin Hunter
Pinata manages off-chain data for blockchain applications — the infrastructure most NFT marketplaces (OpenSea, Rarible, and many others) quietly rely on. Kyle Tut, co-founder and CEO of Pinata, explains why on-chain storage is economically impractical (roughly $4M per GB on Ethereum) and how IPFS content identifiers (CIDs) give NFT creators tamper-proof references to their underlying files — you cannot silently swap out a CID the way you can a traditional Dropbox link. The demo covers Pinata's Dropbox-style upload UI, IPFS infrastructure run by Pinata to keep retrieval fast, dedicated per-customer gateways that serve IPFS content from your own domain (mypinata.cloud or your TLD) while preserving CID-level integrity, and Pinata's audit-trail approach for legitimately-updatable NFTs in gaming and interactive-art use cases.
Soups Ranjan & Aditya Goel
Soups Ranjan, CEO and co-founder of Sardine, walks through the Sardine fraud and compliance API — a single endpoint for fintechs, crypto exchanges, challenger banks, and NFT platforms to prevent fraud, run KYC, monitor crypto transactions, and stay on top of AML and sanctions (PEP/SDN) screening. The demo shows how Sardine catches fraudsters running mobile emulators like BlueStacks, disposable phone numbers, and stolen dark-web identities — combining behavioral biometrics, device intelligence, and telco/social-graph enrichment with live Chainalysis and Coinbase Analytics calls. A no-code rule editor lets ops analysts chain dozens of fraud and AML typologies without writing code, and adverse-media signals cut AML false positives that plague traditional transaction-monitoring rules.
