Otterspace implemented EIP-4973 account-bound tokens and served as an active contributor to that Ethereum specification. Its badges were non-transferable NFTs covering achievements, roles, and reputation, and the protocol integrated with Snapshot for on-chain governance workflows. Deployed on Optimism Mainnet, the protocol was designed as an Optimism-first solution for communities building badging systems with expirable and non-transferable NFTs for engagement, retention, and trust.
Otterspace raised $3.7M in a pre-seed round at a $20M post-money valuation in May 2022. That round was backed by Cherry Crypto, Inflection, Bessemer Venture Partners, Coinbase Ventures, btov Partners, and Paua Ventures.
