Routines Frontend Integration

Find All Routines Contracts

Routines Contracts are Factory-Based, which means that they are created by sending some directives to a Factory Smart Contract having a fixed address that can be found at the following links for mainnet and ropsten.

You can find all the needed ABIS here.

var deployEvent = "FixedInflationDeployed(address,address,bytes)";

var fixedInflationFactoryAddress = "0x285427916a9d2e991039A8F1611F575D0a6cf237";

var fixedInflationFactory = new web3.eth.Contract(abis.FixedInflationFactoryABI, fixedInflationFactoryAddress);

var logs = await web3.eth.getPastLogs({
    address : fixedInflationFactoryAddress,
    topics : [
        web3.util.sha3(deployEvent)
    ],
    fromBlock : '11882329',
    toBlock : 'latest'
});

var allFixedInflationContracts = logs.map(log => web3.eth.abi.decodeParameters("address", log.topics[1]));
