// Dependency injection for the vendored DGB modules.
|
||
|
|
//
|
||
|
|
// These files were vendored from @dgb-wallet/core and imported
|
||
|
|
// "bitcoinjs-lib", "bip32", "ecpair" and "@bitcoinerlab/secp256k1" as bare
|
||
|
|
// specifiers. That resolves fine in a dev checkout, where Theseus's
|
||
|
|
// node_modules sits above the add-on — and fails for every OTA install, where
|
||
|
|
// Aegis lives in <userData>/extensions/aegis/ and Node's ESM resolver has
|
||
|
|
// nowhere to find them. index.js caught the failure and set dgbCore = null,
|
||
|
|
// so DigiByte quietly stopped existing and an import died with "DGB adapter
|
||
|
|
// not available". It worked on a fresh install and broke after the first
|
||
|
|
// update, which is the worst possible shape for a bug.
|
||
|
|
//
|
||
|
|
// index.js already holds all of these via api.require (which resolves against
|
||
|
|
// the app tree), so it injects them here before importing anything under
|
||
|
|
// lib/dgb/. Every consumer reads them through the accessors below rather than
|
||
|
|
// capturing them at module scope, so nothing depends on import order and a
|
||
|
|
// missing injection fails loudly at the call instead of silently at load.
