example 1. create userOperation from operation.fact

const sender = "0x5279AebbF6e284594521d44612157147dF5ff248fca";
const receiver = "0x9E14a47B76F154A8e0f22cb213b3A1966800Ea0efca";
const currency = "MCC";

const op = mitum.currency.transfer(sender,receiver, currency, 10);
const contract = "0xdC521b33609647F949427A2330c136EfC3171535fca";
const userOp = mitum.aa.createUserOperation(op.fact, contract, "did:dxd:0x5279AebbF6e284594521d44612157147dF5ff248fca#auth_key");
console.log(userOp.toHintedObject());

// output
