Build the future of blockchain technology with an EOSIO Smart Contract.

Be the first to solve Block.one’s EOSIO Smart Contracts Challenge and win $200,000.





Block.one, the leading provider in high-performance blockchain solutions, is challenging developers, professionals, and hobbyists alike to test their skills, showcase their potential, and transform technology as we know it.

In this challenge, participants must create an EOSIO Smart Contract which can store and invoke EVM (Solidity) Smart Contracts in a virtual Ethereum-like environment. The challenge enables developers in the EOSIO, Ethereum, and wider blockchain communities to use their preferred development platforms while leveraging the benefits of EOSIO. For example, EOSIO can process smart contracts faster, reducing the impact of a significant roadblock for developers.

How it works:

Participants will have up to one year from the submission launch date to solve the challenge — whoever is the first to solve it wins the prize.

The winner of the prize will be the first to solve the challenge so we encourage all participants to get started!

The challenge submission period will close if a prize winner is announced, even if before the expiration date of February 3, 2021.

The format for submissions is strict - learn the process here.
