I'm trying to submit many operations in a single transaction that are built up dynamically. How can I convert these operations to a Stellar Transaction?

Please provide code samples if possible.

You could use the spread operator on an object of type []build.TransactionMutator that is passed into the build.Transaction method (on github.com/stellar/go/build).

Here's a code sample:

import (

// BuildWithOps builds a transaction with a dynamic list of operations
func BuildWithOps(sourceAccount string, seq uint64, network build.Network, ops []build.TransactionMutator) (*build.TransactionBuilder, error) {
    // build an array of mutators initialized with the essential values
    muts := []build.TransactionMutator{
        build.Sequence{Sequence: seq},
        build.SourceAccount{AddressOrSeed: sourceAccount},

    // dynamically add more mutators/operations as needed
    muts = append(muts, ops...)

    // build the transaction from these mutators and check for an error
    tx, err := build.Transaction(muts...)
    if err != nil {
        return nil, err
    return tx, nil

    One note, tx.Err not longer exists. build.Transaction returns tx and err. Feb 1, 2018 at 22:19
