Sure thing. Here's my revised version:
function isLikelyCoinjoin(txdata) {
// Check number of inputs/outputs
const numInputs = txdata.vin.length;
const numOutputs = txdata.vout.length;
if (numInputs > 1 && numOutputs > 2) {
// Check outputs have close to the same value
let outputValues = txdata.vout.map(o => o.value);
outputValues.sort((a, b) => a - b);
let difference = outputValues[numOutputs - 1] - outputValues[0];
if (difference < 0.001) {
// Check if there is at least one change address
let changeAddressIdx = outputValues.findIndex(v => v < 0.01);
if (changeAddressIdx >= 0) {
// Check if all inputs are from the same wallet
let isInputFromSameWallet = txdata.vin.every(vin => {
return vin.prevout.addr === txdata.vin[0].prevout.addr;
});
if (isInputFromSameWallet) {
return true;
}
}
}
}
return false;
}
