Clave's Solution: Re-imagining Wallet UX

Seamless UX, Enhanced Security, and the RIP-7212 Standard

Re-imagining the User Experience

In the world of Web3, creating user-friendly experiences for applications, including wallets and decentralized applications (dApps), continues to be a significant bottleneck for mass adoption. The stark difference in user experience between Web2 apps and Web3 technologies presents a major obstacle to their widespread adoption.

To address this challenge, Clave, a Smart Contract wallet application, has emerged. It improves the user experience and enhances security through advanced hardware-level protection leveraging Apple's Secure Enclave system, enabling users to interact with Ethereum without the need for seed phrases or private keys using their biometric data.

Clave’s main value proposition is based on research from Account Abstraction and Elliptic Curve Cryptography (ECC). Specifically, Rollup Improvement Proposal 7212 (RIP-7212) which introduces a pre-compiled contract for verifying signatures on the secp256r1 elliptic curve.

This allows any Ethereum Virtual Machine (EVM) compatible chain to easily integrate this contract which enables users to sign transactions using their biometric data.

Clave aims to bridge the gap between the satiability of Web2 UX and evolving Web3 by providing a seamless and secure onchain payments user experience.

Note: For more information on the technology and the importance of pseudorandom elliptic curves in ensuring a seamless user experience (UX) for crypto-native apps, please read this article.

Clave’s Technology: Enhancing User Experience

Clave is an onchain payment solution that incorporates Account Abstraction to enhance its functionalities. Its main objective is to provide users with a seamless Web3 payments solution while ensuring strong hardware-level security.

By leveraging the secure components found in everyday devices like phones, tablets, and select notebooks, Clave simplifies user onboarding by implementing biometric authentication.

Simplifying dApp's UX

While the greater Ethereum community focuses on onboarding the Next Billion users, it sometimes underestimates the learning curve that non-technical individuals encounter with decentralized applications.

These applications, often cumbersome and high-maintenance, pose greater security risks than their Web2 counterparts, like Venmo. Main challenges include securely managing non-custodial wallet keys and limited recovery options in case of key loss.

The prevailing view suggests that users should be sufficiently technical in order to take control and ownership of one's digital assets and data on the internet.

However, what if it were possible to match or even surpass the user experience of traditional payment apps without compromising data sovereignty? Enter Clave.

Clave beta app (2024)

That is what Clave aims to do. When exploring the Clave beta app, the user interface immediately feels familiar, seamlessly combining the best features of apps like Venmo and MetaMask, and presenting them in a straightforward manner. Its design focuses on essential elements, avoiding the common Web3 issue of overwhelming the user.

How Clave Addresses Web3 UX Challenges

Clave’s approach involves the use of Secure Enclave and similar Trusted Execution Environment (TEE) technologies to enhance security. Secure Enclave is a hardware module in Apple iPhones that operates as an isolated processor, separate from the operating system, and runs immutable code.

The presence of a hardware component for secure password storage, separate from the core processor and requiring users' biometric information for access, is an elegant solution.

This innovative approach eliminates the need to store private keys or seed phrases, making the entire process more straightforward while still ensuring heightened security without compromising the user experience.

Road to Devconnect 2023

The initial concept for developing a smart contract wallet controlled via a Secure Enclave, originated during the ETH Global Hackathon in March 2023. After achieving finalist status, the team was inspired to further refine and expand upon this concept, leading to subsequent developmental efforts.

Since then, there has been a continuous evolution of smart contracts and libraries, supporting not only Secure Enclave but also all structures within Trusted Execution Environments (TTE). Clave, as the pioneering application utilizing the technology, made its debut on zkSync testnet at Devconnect Istanbul. The ultimate goal is to present a fully functional product accessible on Mainnet to a wider audience in the coming months.

Introducing RIP-7212

Ulaş Erdoğan and Doğan Alpaslan spearheaded the initiative, RIP-7212 (formerly known as EIP-7212), which aims to enhance Ethereum's user experience and security. Their innovative approach integrates Apple Secure Enclave's signature capabilities with Ethereum smart contracts.

This was partly inspired by the realization that Trusted Execution Environments (TTE) like Apple’s Touch/Face ID and Android Biometrics, including the Secure Enclave, predominantly use the NIST approved secp256r1 elliptic curve, a standard in nearly all devices.

The Secure Enclave is configured to support the secp256r1 elliptic curve, also known as prime256v1 or P-256, different from the secp256k1 curve used by Ethereum and Bitcoin.

To address this compatibility challenge, the team proposed EIP-7212, officially published in June on the Ethereum Magicians forum. This proposal aims to incorporate the secp256r1 elliptic curve into Ethereum as a precompile, creating a vital link between Web2 and Web3 technologies.

After extensive discussions, a consensus was reached on the EIP's specifications. Consequently, the decision was made to transition the EIP into a new standard, the Rollup Improvement Proposal (RIP), in light of the growing prevalence of passkey and Secure Enclave-based Account Abstraction wallets in Layer 2 solutions (L2s). This transition marks the first merged RIP.

EIP-7212 → RIP-7212

RIP-7212 addresses this difference by offering a cost-effective and secure verification method for the P256 curve, which is widely used in Web2 authentication systems such as biometric authentication, FIDO2, and Secure Enclave-based signers.

Clave, built on the RIP-7212 standard, generates a new key pair on the user's mobile device. The public key is then added to the smart wallet contract as an authorized key. Users can easily manage their wallets by using their biometric data for signing transactions on their devices.

This approach eliminates the requirement for users to comprehend and safeguard seed phrase structures, ensuring a faster and more secure onboarding experience into the blockchain world.

During the final all-core devs meeting of 2023, the precompile address was established as '0x100,' and the following two weeks were dedicated to finalizing the specifications. As we enter 2024, the finalization process is expected to remove any obstacles to integrating the precompile across all rollups.

It is worth noting the ongoing collaboration amongst EVMs like zkSync, Polygon, and Evmos, who have been diligently working on incorporating the precompile and have recently announced their intention to integrate it onto Mainnet.
