The ICN token for ICONOMI, a Slovenian decentralized crypto fund management platform that raised $10.5M in its 2016 ICO — the third-largest crowdsale in Ethereu
Token Information
Key Facts
Description
ICONOMI was a cryptocurrency fund management platform founded by Jani Valjavec and Tim Zagar in Slovenia. The ICN token contract was deployed on October 24, 2016, issuing 100 million ERC-20 compliant tokens representing ownership in the ICONOMI platform.
The ICONOMI ICO ran from August 25 to September 26, 2016, raising over $10.5 million from 3,398 contributors. At the time, it was the third-largest crowdsale in Ethereum history, behind only The DAO and Ethereum's own genesis sale. It was also the largest European fintech crowdfunding project of 2016.
The platform's vision was to become the "Uber of fund management" — enabling anyone to create and manage crypto investment funds. Stage 1 launched two instruments: ICONOMI.INDEX (passive crypto index fund) and ICONOMI.PERFORMANCE (actively managed fund). Stage 2 planned an Open Fund Management (OFM) platform allowing anyone to introduce and manage their own crypto funds.
To ensure fair token distribution, the contract included a block-lock mechanism: tokens were locked until Ethereum block height 2,505,000 (approximately October 25, 2016 at 1 PM UTC), preventing any transfers until after distribution was complete. A test token contract had been deployed earlier at block 2,473,590 for validation purposes.
ICONOMI later pivoted to become a regulated digital asset management platform, continuing operations beyond the ICO era. The ICN token was eventually deprecated in favor of a new token structure as the platform evolved.
