I use truffle-contract for contract abstraction.

const myContract = TruffleContract(MyContractArtifact);

myContract.setProvider(web3.currentProvider);

I'm using Infura as the web3 provider so need to sign transactions before sending them. If I want to use contract functions in the web3.eth.accounts.signTransaction data field, can this be done with the myContract instance? I understand it can be done with web3.eth.Contract based on this answer, so if it is actually possible, is it more or less the same technique, or what would I need to do?

Edit* I have given up on truffle-contract and using web3.eth.Contract.methods.myMethod.encodeABI()

Edi2* Changed title as I was wrong to say sendTransaction() - the method I require is sendSignedTransaction()

  • What are you trying to do? Do you want to create a "raw" to contract?

    Sorry Ismael I'm not sure what that is. Basically, if truffle-contract has the equivalent of web3.eth.Contracts.method.encodeABI() (which is what you might have meant.) I have actually given up on truffle-contract and moved to the web3 contract abstraction, and have an offline signing solution in place that uses web3.eth.sendSignedTransaction
