Hey @tan,

do you also pass the `walletId` in the `X-End-User-Wallet-Id` header?

Nope, now added now getting this error , `https://ncw-developers.fireblocks.com/docs/create-transaction`

```auto
{
    "message": "Unauthorized: Token was not accepted.",
    "code": -7
}

```

So i need to add the asset `ETH_TEST5` to every ncw wallet to just to do a contract call ?
