Developed Ethereum-compatible wallets on NEAR by implementing NEP-518 protocol changes in the near/NEPs repository, focusing on cross-chain interoperability and streamlined onboarding for decentralized applications. Introduced implicit accounts and automated wallet contract deployment, allowing wallets to be created seamlessly on first use. Added Ethereum-like APIs such as get_nonce and rlp_execute, enabling validation of Ethereum transactions within the NEAR ecosystem. Leveraged expertise in blockchain technology, protocol design, and smart contracts, with documentation and specifications written in Markdown. This work established a technical foundation for broader DeFi and wallet integrations, reducing friction for developers building Ethereum-compatible solutions on NEAR.
