The next wave of crypto will need to be able to scale to millions and remain secure. Think about global payment systems with sub-cent fees, on-chain games that never shut off and financial tools that unlock value at the scale of tens of billions. Re{Solve} is your chance to push the boundaries of blockchain. If you’re an engineer, creator, or a dreamer, this is where you explore what’s possible. WHAT YOU WILL BUILD AND WHY IT MATTERS Projects can be anything:
Serious builds that could grow into seed-funded startups
Playful experiments or “toy projects” created to learn and explore
Explorations of new frontiers like private transactions with no trace
You’ll work with ultra-low fees, security inherited from Ethereum, and the speed needed to build applications for a global audience.
