OFFICIAL TIMELINE
A precise record of the shifts, products and moments that shaped Sina Estavi’s professional journey, with clear status and primary sources.
While studying in Mashhad, Sina registered Yekta Exir Sabz and began selling aloe vera products through Facebook. He also encountered Bitcoin, bought personally and sometimes helped people around him transact. This was personal activity, not yet an organised crypto business. Bitcoin began the year near $13 and ended around $730–$760.
After the first business failed, Sina moved to Tehran, built large Telegram marketing channels and began buying and selling digital assets more seriously for himself and people in his network.
A manually operated Telegram service developed into a bot, website and company. It later operated from approximately 3,000 square metres of office space with nearly 200 people at peak, according to Estavi’s public account.
Sina Estavi founded Bridge Oracle, introduced as a blockchain-oracle project designed to connect external data with smart contracts.
Through Valuables, Sina acquired the NFT associated with Jack Dorsey’s first tweet for 1,630.5825601 ETH, valued at $2,915,835.47 at the time. The acquisition concerned the NFT, not ownership of the underlying tweet or its copyright.
Sina was detained and CryptoLand’s operations stopped. Iran International later published an investigation based on reported court documents, a court-appointed expert analysis, blockchain records, video and audio. The detailed evidence record is published separately on this site.
Bridge Oracle was reintroduced as Bridge AI. Its current public focus moved toward AI-assisted blockchain security and trading intelligence.
BridgeMM was publicly shown operating for BRG on BitMart and later described as ready for initial external pilots. It remains in pilot and early rollout, not general availability.
NanoMoz’s Telegram product is active, while its standalone iPhone experience remains in development with private-beta registration open. Bridge HQ is used as the portfolio identity for this current product chapter.
