@scarmuega is there any more clever way to check if a transaction is in fact smart contract transaction?

Right now I am checking if any of the output addresses is in fact smart contract type of address, there could be a more clever way I guess..

[matiwinnetou]

I found this:

pub enum TransactionBodyComponent {
    Inputs(MaybeIndefArray<TransactionInput>),
    Outputs(MaybeIndefArray<TransactionOutput>),
    Fee(u64),
    Ttl(u64),
    Certificates(MaybeIndefArray<Certificate>),
    Withdrawals(KeyValuePairs<RewardAccount, Coin>),
    Update(Update),
    AuxiliaryDataHash(ByteVec),
    ValidityIntervalStart(u64),
    Mint(Multiasset<i64>),
    ScriptDataHash(Hash<32>),
    Collateral(MaybeIndefArray<TransactionInput>),
    RequiredSigners(MaybeIndefArray<AddrKeyhash>),
    NetworkId(NetworkId),
}

ScriptDataHash -> will this be empty if this is not smart contract transaction?

Depends on what you mean by "Smart contract transaction". If you are looking for transactions that execute scripts, then you need to look at input-related components, since script execution only takes place when you're consuming a UTxO that's sitting on a script address. A way of doing this is checking for redeemers in the witness set.

I want to count all interactions with a smart contract address:
e.g.

addr1w999n67e86jn6xal07pzxtrmqynspgx0fwmcmpua4wc6yzsxpljz3
