DI U2U Protocol (Decentralized Interoperability)

Welcome to IU2U Protocol

IU2U Protocol is dedicated to building next-generation cross-chain interoperability solutions using the Interoperable U2U (IU2U) Protocol. Our mission is to enable seamless, gas-efficient, and highly programmable cross-chain transactions, driving adoption and utility for U2U, the native token of the U2U Chain.

🌉 What is IU2U Protocol?

The Interoperable U2U (IU2U) Protocol is a cutting-edge solution that enhances U2U Chain's interoperability, enabling seamless asset transfers, smart contract execution, and data messaging across multiple blockchain ecosystems.

IU2U Protocol aims to revolutionize cross-chain DeFi by delivering a seamless, gasless user experience that eliminates the need to hold native tokens across multiple blockchains. Through innovative gasless meta-transactions powered by U2U-based credit systems, users can execute transactions without managing gas fees, while our advanced DEX aggregation across 37+ protocols ensures optimal swap rates and liquidity access.

At its core, IU2U provides lightning-fast, secure cross-chain operations for token transfers, data messaging, and smart contract execution across Ethereum, BSC, Polygon, Avalanche, Arbitrum, Optimism, and Base. Built on the U2U Solaris Mainnet, Nebulas Testnet with 1:1 U2U token backing, our decentralized relayer network and robust security model establish IU2U as the foundational infrastructure for next-generation cross-chain dApps, enabling frictionless interoperability and unprecedented user adoption in the multi-chain ecosystem.

🌟 Key Features

1️⃣ Gasless Meta-Transaction System (U2U as Primary Gas Token)

• Users pay gas fees exclusively in U2U, regardless of the blockchain they interact with.

• Supports Ethereum, BNB Chain, Polygon, Optimism, Base, and any EVM-compatible chain.

• Simplifies user experience by abstracting gas fees and reducing transaction friction.

• Support batch transfers (multiple token transfers to multiple user at once) and gasless-swap.

2️⃣ Enhanced U2U Interoperability (Replacing WU2U)

• Eliminates the need for wrapped U2U (WU2U) by introducing a native cross-chain U2U token.

• Enables data transmission and smart contract execution alongside asset transfers.

• Expands U2U’s programmability across different chains, making it more developer-friendly.

3️⃣ Cross-Chain Swap Powered by U2U

• DEX Aggregator & Liquidity Router ensures the most efficient swaps using U2U for gas.

• Gas Fee Abstraction:

  • Off-chain transaction signing to reduce gas costs.

  • Automatic U2U Gas Conversion where required.

  • Meta-Transaction Relayer executes transactions on behalf of users.

4️⃣ Cross-Chain Bridge & General Message Passing (U2U-Based)

• Supports advanced cross-chain token transfers, data transmission, and smart contract interactions.

• Cross-Chain Smart Contract Calls allow contracts on one chain to trigger actions on another.

• Future support for non-EVM blockchains to expand the IU2U ecosystem.

5️⃣ High-Performance Optimization

• Routing Algorithm finds optimal paths for cost-effective swaps.

• Batch Transactions reduce fees by bundling multiple operations.

• Dynamic Fee Structure optimizes gas costs to encourage frequent transactions.
