Curta is an onchain EVM capture-the-flag competition platform where players solve generative puzzles, with valid solutions minting Flag NFTs and awarding leaderboard points. Curta's Twitter Score is 32 out of 1000 as of September 2026, ranking #30,453 (top 10%) among 492,478 tracked accounts.
Curta was founded by Shane Fan and operates as a subsidiary of Waterfall. The platform runs an open-source protocol deployed on Ethereum mainnet and Base mainnet, through which puzzle authors and solvers engage in a talent-discovery competition format. Each puzzle uses a solver's own wallet address as a seed, generating a unique starting position for every participant. Two NFT credential types underpin the system: Flag Tokens for solvers who submit valid answers, and Authorship Tokens that grant holders the right to author a puzzle.
Curta co-hosted Curta Cup, an online and in-person EVM CTF event alongside Linea, with sponsorship from Base and Zuzalu. Curta also participates in a Hacker in Residence experiment that retroactively funds open-source Ethereum work through monthly ETH streams, a program funded by BuidlGuidl. Curta has published 630 posts and has been mentioned by 24 accounts a total of 45 times.
