During July 2025, contributed to the opentensor/subtensor repository by implementing BN128 precompiled contracts to support elliptic curve operations such as modular exponentiation, pairing, and addition. This work enhanced the cryptographic capabilities of the runtime, ensuring compatibility with Ethereum Virtual Machine (EVM) standards. The approach involved updating dependencies and registering new precompiles within the system, with all changes written in Rust. Additionally, the runtime specification version was incremented to maintain alignment with external tooling and upcoming network upgrades. The focus remained on feature delivery and maintainability, with no high-severity bugs reported during this period of development.
