One of the most promising technology for Internet of Things (IoT) is block chain which can help to securing transaction and contracts in Collaborative Economy. Because of some features of block chain are not enable to fetch in off-chain data, so it is necessary to provide and enable smart contracts in block chain based-IoT environment for innovate business models. This work can help to communicate smart contract such as Ethereum, Tether, Litecoin and etc for business models innovative in outside of IoT platform. Three components, namely Mission Manager, Task Publisher and Worker, are presented in the data carrier architecture which can be interact with contract developer, smart contract, Ethereum node, Tether node, Lite Coin node and off-chain data sources. Representing new solutions for smart contract filtering with new decoding event log due to fitting some requirements applied for optimization which use Ant Colony Algorithm (ACO). Reducing the cost of deployment about 21USD in average for any smart contract is the strength of the method which is efficient and has good performance as innovate business models of Collaborative Economy.
