Mislav Javor

I am an Ethereum and EVM engineer, founder and team leader. I've spent the last 8 years building applicatons on various EVM blockchains, founded two startups, raised $4M+ in VC funding. Professionally, I am a strong first-principles thinker - aiming to get the solutions the users need, while maximizing the backwards compatibility and integration friction.

I've led research and commercialized the following: novel data structure for multi-chain transaction encoding (Klaster Interchain Transactions - later known as Supertransactions), asynchornous orhcestration across multiple chains (Biconomy Modular Execution Environment), ability to enable cross-chain batch execution to all EOA wallet users, and the ability to deploy smart accounts up to 90% cheaper than with CREATE2 (known as PREP Accounts).

I have been a speaker at industry events such as DevCon, DevConnect, EthCC, BlockSplit and many others.

In a previous life, I founded an RWA tokenization startup - aiming to get renewable energy sources onchain. In that role, I've managed to secure $30M+ pipeline of tokenization projects - with industry partners such as Greenpeace.
