gnosis safe tx builder

Overview

Ape Safe: Gnosis Safe tx builder

Ape Safe allows you to iteratively build complex multi-step Gnosis Safe transactions and safely preview their side effects from the convenience of a locally forked mainnet environment.

Installation

pip install -U ape-safe

Quickstart

brownie console --network mainnet-fork
from ape_safe import ApeSafe
safe = ApeSafe('ychad.eth')

dai = safe.contract('0x6B175474E89094C44Da98b954EedeAC495271d0F')
vault = safe.contract('0x19D3364A399d251E894aC732651be8B0E4e85001')

amount = dai.balanceOf(safe.account)
dai.approve(vault, amount)
vault.deposit(amount)

safe_tx = safe.multisend_from_receipts()
safe.preview(safe_tx)
safe.post_transaction(safe_tx)

See Documentation for more examples and full reference.

Comments
  • Question: Is there a workflow to sign the safe tx using a ledger based account?

    Question: Is there a workflow to sign the safe tx using a ledger based account?

    Considering the security focus of Gnosis Safes it seems counterproductive to require the private key to reside on the machine where the ape-safe tools are used.

    When invoking method on contract I receive ValueError: eth_sendTransaction does not exist

    I am trying to have a gnosis safe invoke the mint function on an ERC20 to which it has the permissions to do so.

    Below is my code in which I follow the way presented in the quickstart of the documentation.

    When I run this code, it errors out at ovl.mint with the error ValueError: The method eth_sendTransaction does not exist/is not available

    def main():    
      gov = dotenv_values()['GOVERNANCE']    
      safe = ApeSafe(gov)            
      ovl = safe.contract("0xfa474A313BDBF69E287dbef667e2f626ea2574Df") # Must have a checksummed address          
      ovl.mint("0xA600AdF7CB8C750482a828712849ee026446aA66", 1e18) # method takes (address,uint) 
    

    When I run this code, I get this stack trace at ovl.mint()

    I followed these https://safe.ape.tax/quickstart.html instructions and when I try to run scripts or a brownie console to import ApeSafe from ape_safe, it gives me an error saying there is no module named ape_safe.

    Python version in the brownie console is 3.8.9 Python3 version is 3.9.10 Python version is 2.7.18 Brownie version 1.17.2 Pip3 version is 22.2.2 Pipx version is 1.0.0 Pip version is 22.0.4

  • Can't sign tx to test if I am not part of the ms

    Can't sign tx to test if I am not part of the ms

    CMO allowed me to test a tx and sign even when I was not an owner of a delegate of the ms. With ape-safe I get:

    ApiError: Error posting transaction: b'{"nonFieldErrors":["Sender=0x0 is not an owner or delegate. Current owners=[\'0x0\', \'0x0\', \'0x6F2A8Ee9452ba7d336b3fba03caC27f7818AeAD6\']. Delegates=[]"]}'

    At the beginning I thought it was a gnosis upgrade, but I just run a tx with ape-safe installed and I could sign to test without issues.

    I guess ms.preview(tx) is not doing the same thing as estimate_safe_tx(safe_tx)

  • simulate all pending txs before preview

    simulate all pending txs before preview

    problem

    it feels bad when a tx in the queue rugs a tx you have carefully crafted.

    solution

    add a flag to preview to simulate all the txs in the queue, so you arrive at a more correct state.

    good first issue

  • feat: add Trezor eip-712 signing support

    feat: add Trezor eip-712 signing support

    Trezor T now has support for EIP-712 clear signing; this adds Trezor + EIP-712 sig support in Ape Safe

    Changes (in sign_with_trezor()):

    • added EIP-712 support
    • added force_eth_sign param to force use of eth_sign instead of EIP-712 signatures
    • sign_with_trezor() will now prefer EIP-712 signatures if the connected Trezor is compatible (based on model + fw version). Otherwise (or if force_eth_sign is truthy), it'll stick with eth_sign signatures.

    This might need another update if and when Trezor adds EIP-712 signing support in Trezor One (client.features.model == "1") -- plus, it seems like Trezor is planning on only having blind-signing support on the T1 (trezor/trezor-firmware#1970), so a bit of extra work might be needed for future T1 support

    Tested on Trezor T with fw version v2.4.3; both EIP-712 and eth_sign signatures work fine.

  • feat: add Trezor signing support (through trezorlib)

    feat: add Trezor signing support (through trezorlib)

    Added ability to create eth_sign SafeTx signatures with trezorlib. Adds new function sign_with_trezor(safe_tx, derivation_path, use_passphrase)

    Passphrase support is kind of rudimentary; I believe it might not work on the Trezor One because you can't enter a passphrase on-device with it. We could probably do on-host passphrase input though. Otherwise, it defaults to no passphrase (and skips any passphrase prompts), which will probably work on a T1

    Tested w/ a Trezor T on fw v2.4.2.

    (also, worth noting that EIP-712 support is now in master for TT; we can probably add signTypedData support too)

    (would also appreciate if someone with a T1 could test it out)

  • feat: hardware wallet support via frame signer

    feat: hardware wallet support via frame signer

    Add ability to sign Safe transactions using Ledger, Trezor and Lattice1 via Frame.

    Tested on Ethereum Mainnet with Ledger Nano X.

    New API:

    • get_signer()
    • sign_with_frame(safe_tx)
    • post_signature(safe_tx, signature_
    • pending_transactions
    • confirmations_to_signatures(confirmations)
    • execute_transaction

    Some specific combinations I want tested:

    • [ ] safe on any network but eth mainnet which has a ledger as owner (ledger doesn't support eip155 and i want to see if i implemented the fix for it correctly)
    • [ ] safe on any network with any trezor model as owner
    • [ ] safe on any network with lattice1 as owner

  • May not work for some installation with the trezor from `0.13.0`

    May not work for some installation with the trezor from `0.13.0`

    The problem is in simple-rlp dependency introduced by trezor, see the issue.

    <...>
        class HashableRLP(rlp.Serializable):
    AttributeError: module 'rlp' has no attribute 'Serializable'
    

    Possible workaround ~~for those who doesn't rely on trezor~~:

    rm -r .direnv/python-3.9.16/lib/python3.9/site-packages/rlp-2.0.1.dist-info
    rm -r .direnv/python-3.9.16/lib/python3.9/site-packages/rlp
    pip install rlp==2.0.1
    

    By the way, simple running pip install ape-safe from scratch does the thing because of order of packages installation.
