NEAR FUSION+ Smart Contract Development
NEAR Fusion+ is a comprehensive DeFi protocol that migrates 1inch's proven Limit Order Protocol and Cross-Chain Swap functionality to the NEAR blockchain. The system provides two primary capabilities: advanced limit order trading with partial fills and extensible features, and atomic cross-chain swaps secured by time-locked escrow contracts.
Implementation Limit Order Protocol
Core Components
- Compact: ERC-6909 enabled Chainlink calculator for price discovery
- ResourceManager: Manages resource locks for ERC-6909 integration
- TychoSwapExecutor: Executes complex swaps using Tycho Execution
- CompactInteraction: Post-interaction handler for resource allocation
- RebalancerInteraction: Treasury management and portfolio rebalancing
- OracleCalculator: Price oracle integration for advanced order strategies
Key Features

- Oracle Integration: Chainlink price feeds for accurate pricing
Key Technology Enhancements
- Solidity based tests including a migration from
OrderUtils.jsto solidity based OrderUtils - Solidity
^0.8.30compatibility provided by creating an interface ILimitOrderProtocol.sol and introducing LimitOrderProtocolManager for testing.
