## Transaction builder
Here are a couple of libraries for building transaction builders.
these are still used but have not been real active in maintaining.
https://github.com/gnosis/react-multisend
&
https://github.com/gnosis/ethers-multisend
the transaction builder Safe app

## Gas estimation
- the way we are doing it might not be requiered. (using baalGas)
- exec on zodiac module should return a false if failed for any reason
- im not sure this is true, TODO: get an example failed tx back to them
examples of how they have handled the same griefing problem which might shed some light into other solutions

## module proxy factory
- new address is in zodiac repo now. should be able to be deployed to all chains if has not been already
- 0x00000000000... in zodiac repo now
- src/deployments 1.1.0
- process for replay deploy
- can look at deploy params and do any chain replay ( if script doesn't work).
to create a similar approach with our shaman deployments
- look at singleton deployment script - root contract - ex. poster contract deploy script
- or EOA that reserves nounces (fragile, not great)
- note: could use a vanity addresses

## API
reliability for api / will there be charges?
- as reliable as a hosted service can be
- should be fine on most chains
- no plans for charges but who knows
## G0 audit
- still in audit backlog with them
- being pushed back by internal projects
- they will let us know if it gets time
