Example

The contents of the contract file TradeOffer(without file suffix restrictions) are as follows:

contract TradeOffer(assetRequested: Asset,
                    amountRequested: Amount,
                    seller: Program,
                    cancelKey: PublicKey) locks valueAmount of valueAsset {
  clause trade() {
    lock amountRequested of assetRequested with seller
    unlock valueAmount of valueAsset
  }
  clause cancel(sellerSig: Signature) {
    verify checkTxSig(cancelKey, sellerSig)
    unlock valueAmount of valueAsset
  }
}

Compiler contract file to generate the binary:

./equity TradeOffer --bin

the return result:

======= TradeOffer =======
Binary:
547a6413000000007b7b51547ac1631a000000547a547aae7cac

Query the clause shift for contract:

./equity TradeOffer --shift
