@babbage/go

A production-minded BRC-100 WalletInterface wrapper that keeps onboarding, error handling, and funding flows conversion-focused. Babbage Go now ships with an opinionated emotional design system so Metanet apps can feel branded from the very first modal.

Quick start

npm i @bsv/sdk @babbage/go

import BabbageGo from '@babbage/go'

const wallet = new BabbageGo()
await wallet.createAction({
  description: 'Launchpad mint',
  outputs: [{
    satoshis: 1,
    script: '016a',
    outputDescription: 'Generic Token'
  }]
})

Pulse Bloom design system

Our new Pulse Bloom system gives every interaction an immediate tone without forcing you to hand-roll CSS. It blends glassy layers, tactile buttons, and emotional color grading while remaining fully overridable.

| preset | vibe | When to use | | --- | --- | --- | | auroraPulse (default) | cool neon optimism | consumer onboarding, read receipts, progressive disclosure | | emberLagoon | warm ritualized concierge | premium drops, tips, funding prompts | | midnightHalo | crisp editorial minimalism | enterprise dashboards, light-mode sites |

Custom controls

• Token overrides for every color, shadow, font, and card radius (design.tokens).
• Button geometry via buttonShape: 'pill' | 'soft' | 'sharp'.
• Drop-in brand CSS with design.customCss (legacy styles still works and is merged automatically).
• Modal copy for wallet-unavailable + funding flows remains configurable via their respective option blocks.
