Scalus Multiplatform Tx Builder API will allow to construct transactions on both JVM and JavaScript platforms. Thus freeing developers from implementing the same logic twice.
Often we need to build same transactions on backend and on front end.
If your backend is JVM you need to implement the logic twice.
Please describe your proposed solution
Add to Scalus a Tx Builder API following best and familiar transaction building practices in MeshJS, Lucid and Cardano Client Lib.
Use MeshJs and Cardano Client Lib as the implementations for JavaScript and JVM platforms respectively.
This API will allow to reuse transaction building logic on both JVM and JavaScript platforms. Thus freeing developers from implementing the same logic twice.
Please define the positive impact your project will have on the wider Cardano community
This Scalus Tx Builder API will save time and money by freeing developers from implementing the same transaction building logic twice.

I won several grants in Fund 11 for Scalus and we're making progress and deliver results.
What are the key milestones you need to achieve in order to complete your project successfully?
Milestone 1: Design and implement Scalua Tx Builder API
Milestone 2: Implement JVM backend bindings to Cardano Client Lib.
Test the integration.
Milestone 3: Implement JavaScript API bindings to MeshJS or Lucid Evolution
Test the integration.
Final Milestone: Add documentation and examples.
Use the Tx Builder API in Scalus Starter project.
Produce final report.
Who is in the project team and what are their roles?
The main proposer, Alexander Nemish will be actively working on the proposal along with Ruslan Shevchenko rssh – another prominent Scala and blockchain engineer/architect.
I’m a former compiler engineer at IOG, I worked on Marlowe DSL (https://marlowe.iohk.io).
I'm the author of Scalus - DApps Development Platform for Cardano.
I won several grants in Fund 11.
I’m a senior Scala engineer with more than 10 years of Scala development experience with companies like UBS and Deutsche Bank.
Please provide a cost breakdown of the proposed work and resources
We estimated 2.5 months of development.
2.5*160h*** 75/0.3=100,000 ADA.
No dependencies.
How does the cost of the project represent value for money for the Cardano ecosystem?
Scalus Tx Builder API will save many hours of reimplementing the same transaction building logic on backend and frontend for those who use JVM for backend, the most used platform for backend on the planet.
