brightledger-assets-lib

Browser-safe domain library for the BrightLedger programmable asset layer.

Provides typed action payloads, a canonical CBOR serializer, Asset ID derivation, and SDK constructors. Designed for use in both browser and Node.js environments.

Features

• Typed payloads — All 18 asset action kinds with discriminated-union IAssetAction
• Serializer — AssetActionSerializer: versioned CBOR encoding / decoding with MalformedActionError on invalid input
• Asset ID derivation — deriveAssetId(issuerPublicKey, issuanceEntryHash) using SHA-256 (browser-safe via @noble/hashes)

Installation

yarn add @brightchain/brightledger-assets-lib

Usage

import { AssetActionSerializer, deriveAssetId, ActionKind } from '@brightchain/brightledger-assets-lib';

const assetId = deriveAssetId(issuerPublicKey, issuanceEntryHash);

const action: IIssueAssetAction = {
  kind: ActionKind.IssueAsset,
  symbol: 'TKN',
  // ...
};

const bytes = AssetActionSerializer.serialize(action);
const decoded = AssetActionSerializer.deserialize(bytes);
