you mean in rosetta?

SmartPy

yes, I have already created a lot of contract in smartpy for that paper, now I'm refactoring using modern syntax

SmartPy

You'll push that to rosetta smart contracts? Thank you!

Here is a SmartPy version of the constructor.
Notice that I did: self.data._payees = reversed(payees) outside of the _addPayee function as it's less strange. SmartPy doesn't have any append.
An easier version to read could be this one. The performance is reduced but we don't really care as it's in the constructor.

I managed to this:

counter_p = 0
counter_s= 0
done = False
for payee in payees:
done = False
counter_s = 0
for share in shares:
if not done:
for i in range(payees_len):
if i == counter_s and i == counter_p:
assert payee != sp.address("0"), "PaymentSplitter: account is the zero address"
assert share > 0, "PaymentSplitter: shares are 0"
assert not self.data.shares.contains(payee), "PaymentSplitter: account already has shares"

self.data.shares[payee] = share
self.data.total_shares += share

done = True

counter_s += 1
counter_p += 1

i am trying to test balances of accounts interacting with contracts. below an example with comments. can you confirm that this is expected behavior and what is the reasoning behind that?
also, is there a more elegant and consistent way to test such behaviour using test accounts?

Hey there, sounds like you need to set the with_operations=True effects decorator:

Do you have things you'd want us to do? Are you expecting sapling, global constants or anything else?

SmartPy

23 October 2025 17:53

What about things like global constants, sapling etc? Closer alignment with python meaning brining back some meta programming capabilities? Also i feel compilation testing is quite awkward currently and in general to use it requires quite a bit of boilerplate.

SmartPy

23 October 2025 17:05

Hi, there is no public roadmap. At a high level, our focus for SmartPy will remain on closer alignment with Python, continued improvements to the developer experience, and maintaining alignment with the evolution of Tezos.

SmartPy

09 October 2025 09:55

You're right, do you mind adding this in /Users/timothy/projects/repro-test/.venv/lib/python3.13/site-packages/smartpy/static/ for now? We'll ship a fix latter.

SmartPy

08 October 2025 11:34

s.verify is already asserting, you don't need an assert. The error is not great, thank you for the report. Just remove the assert

SmartPy

14 March 2026 17:17

Your old implementation wasn't correct.

SmartPy

14 March 2026 17:10

@TheMastroDev I just read the specification.
I don't think it's a good idea to create a contract as close as Solidity I just did or maybe as close as you did.
I think the constructor can perfectly receive things in a better shape so it simplifies everything.

SmartPy

14 March 2026 17:04

I edited my example. I added reversed around the result of the function, otherwise we return it in the wrong order.

SmartPy

14 March 2026 16:08

Here is an example on how to implement a zip.
Let me now adapt it to your example.

You're right, that's an error from our simulator. Sorry for that. I'll come back with a fix and a more elegant way of testing that.

Notice that it's only the test system that has a problem, the contracts will behave as expected on-chain.

I don't know if that's clear but setting a contract as the sender doesn't correspond to anything on-chain, that's more a convenient way of writing tests without plumbing the whole.

If you really want to test this way before the fix, you can have add an entrypoint to Wallet that calls MyContract.

im trying to call sp.send and sp.transfer in auxiliary functions and i keep getting __operations__ is not defined.. how to fix this?

SmartPy

23 October 2025 18:16

Yes I mean I would expect smartpy to support all features of Tezos. Especially since some of them were supported in the past

SmartPy

23 October 2025 17:56

For example provide "if x in y" instead of "if y.contains(x)".
Also being more integrated with Python tools and services.
Also having a simpler interaction with the test scenarios.
There is no plan for metaprogramming.

hi guys I get conflicts when installing pytezos and smartpy-tezos (0.23.0) but not with tezos-smartpy (0.22). To reproduce:

this works:

python3.13 -m venv .venv && source .venv/bin/activate && pip install tezos-smartpy pytezos > /dev/null && python -c "import smartpy"

python3.13 -m venv .venv && source .venv/bin/activate && pip install smartpy-tezos pytezos > /dev/null && python -c "import smartpy"

I can't get it to work even with the correct value. not even with this:

import smartpy as sp

@sp.module
def dummy_utils():
    def dummy_function(param) -> sp.nat:
        return sp.nat(1)
    
@sp.add_test()
def _():
    s = sp.test_scenario("simple assert")
    assert s.verify(dummy_utils.dummy_function(()) == sp.nat(1))
