If a winning team has already deployed their project to mainnet by the time winners are announced in August, they will receive 100% of the prize upfront.

Notes

• Mainnet deployment must meet the minimum functional requirements as defined by the Sui team and/or track sponsors.
• Teams are encouraged to continue building post-hackathon to unlock the full prize amount.
• Additional support, opportunities, and ecosystem pathways may be available for top-performing teams.
