@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.
