At the heart of iExchange lies a robust technological infrastructure, powered by a sophisticated network of smart contracts spanning multiple blockchains, including Ethereum L1 and L2s. Leveraging the efficiency of Uniswap v3 contracts, iExchange/iSwap ensures seamless and secure transactions. The iNFTs, following the ERC-1155 token standard, offer flexibility, with the option for custom modifications tailored to specific needs.

Introducing **iStake**, a revolutionary staking mechanism featuring a bespoke smart contract capable of accommodating multiple tokens, encompassing both ERC-1155 and ERC-20 tokens. Participants are rewarded with **iExchange native token**, a standard ERC-20 token, for their staking contributions. This dynamic ecosystem allows for versatile staking options, providing users a holistic and rewarding experience.

The iExchange native token serves as a staking reward and aligns with the ERC-20 standard, ensuring compatibility and ease of integration. As the backbone of the iExchange ecosystem, these innovative technologies collectively create a seamless and efficient platform, catering to diverse user needs across various blockchain landscapes.
