Contribution
Opclave has been one of the finalists among 306 projects at the Scaling Ethereum Hackathon of ETHGlobal by introducing hardware signatures in account abstraction for the first time in the OPStack ecosystem
The Showcase prepared at the ETHGlobal hackathon received significant engagement from the ecosystem, thus introducing Optimism's OP Stack product. Additionally, the Twitter thread featuring Opclave gained over 600K views, contributing to the popularity of OP Stack
The Clave team proposed EIP-7212 to enable the use of the P256 curve. Following this, many individuals from the ecosystem began development on the P256 curve. The Ledger team further developed the work of Opclave. Extensive discussions took place on builder forums, and numerous tweets were posted on Twitter regarding EIP-7212

Renaud's article about secp256r1 curve
Impact
Providing one of the first examples of hardware signing on OP Stack drew the community's attention toward Optimism. The popular thread received not only 600K views but also got RT support from nearly 500 individuals.
After the development of Opclave, Renaud from the Ledger team conducted a study and published an article aimed at reducing the gas fee costs of the 'verifier' contract. This article prompted the entire ecosystem to examine the usage of secp256r1 in OP Stack.
At a time when there were very few projects utilizing OP Stack technology, Opclave emerged and led the way for other projects. After Opclave, many projects worked on Hardware Signing and produced products.
All of these have contributed to increasing the awareness of Optimism Collective among even more people.
