Startrail SDK Playground
not signed in env — wallet — EOA

Try every SDK call against a live wallet

This page is a working integration of @startbahn/startrail-sdk-js. Each card below is one method: fill the form, press Run, and read the exact outcome — the result, a false for a cancelled popup, or the typed error — right under it, with the code you would write.

  2. Sign inlogin() opens the wallet; resolves with the user's EOAs.Sign in →
  3. ActcreateSRR(), transfers, collections… signed through your LUW.Records →

Getting started

Sign-ins open real wallet windows on the selected environment (QA by default). Nothing here writes to the chain until you run a write action.

1Setup

The object passed to new Startrail(config). Any change rebuilds the instance; the generated snippet on the right is what you would paste into your app.

2Brand the login modal new

          
The provider picker is brand-neutral until you say otherwise. Logo, name, colours, light/dark mode, font, corner radius and wording all come from customUi, and mode / accent are forwarded to the wallet UI. Pick a preset or tune it, then Preview opens the real modal — close it to get false back.

        

        

          
          
        

      


      
      

        
3Sign in

          
Each button sets loginProvider, rebuilds the SDK and calls login(). A single provider opens that provider directly; the picker shows the login modal with everything the config allows.

        

          
Sign in with…

4Shared parameters

          
Values every write action needs. Edit them once here; each card lists the ones it uses. They persist across reloads.

        

      


      
      

        
5Startrail Records

          
Mint, update, transfer and annotate SRRs. Write actions sign a meta-transaction and submit it through the LUW; they sign the user in first if needed. Success responses carry a txReceiptId — the chain write itself is asynchronous.

        

      


      
      

        
6Collections

          
Deploy a collection contract and hand it over.

        

      


      
      

        
7Read & batch

          
Read-only helpers that never open a popup, and bulk() for several operations in one transaction.

        

        

      


      
      

        
8Scenarios

          
Multi-step flows that exercise the SDK's session handling end to end.

        

          
Switch user after a page reload

          
Regression test for the persisted-session bug: login A → discard instance → new instance → logout → login must let a different user sign in, not silently return A. Run the steps in order — each login opens the real wallet window. The wallet's own session lives in the cross-origin wallet iframe; only logout() can end it.
