Enabled Ethereum RPC support for the blockchain, developed custom mapping between EVM and Substrate accounts, developed and tested precompiles that make all tokens on the network ERC20-compatible, created CLI interface for interacting with the new features, and enabled its integration with Guardian. Researched XCM, created internal documentation on how to use XCM, fixed XCM configuration for t3rn's parachains to support transfers, created CLI command that enables sending XCM transfers, configured setup enabling automated sending of 1000+ daily XCM transfers on t0rn, and wrote an article on the company's blog explaining how the technology works and what are its future applications.

Configured Zombienet cross-chain logic testing environment, Chopsticks for Pioneer runtime upgrade tests, and upgraded the blockchain runtime to Polkadot version 0.9.43 and 1.1.0. Added WASM-based smart contracts support for the blockchain runtime and created documentation on how to deploy them.

Presented the project during the 2023 edition of the Polkadot Decoded conference. Implemented and tested ERC20, NFT, and metaverse pallet precompiles and created documentation about how to write Solidity smart contracts using them. Developed, tested (end-to-end), and benchmarked decentralized marketing campaign rewards pallet that uses custom Merkle trees. Designed, developed, tested, and benchmarked NFT offers, NFT minting hard limit, and minting, transferring, marketplace listing of stackable (ERC-1155 compatible) NFTs, staking and renting for estates, and NFT tokenization of lands and estates. Developed, tested, and benchmarked multicurrency support for auctions and buy-now listings, as well as royalty and network fees for the network and metaverse-level marketplaces. Upgraded the blockchain runtime to Polkadot versions 0.9.22, 0.9.26, and 0.9.38, and prepared the blockchain to release it as parachain on Polkadot.

Designed, developed, and tested custom local governance pallet for each metaverse.
