feat(statics): add Pearl to statics

[manojkumar138]

Summary

Defines Pearl's coin identity in @bitgo/statics. No utxo-lib changes — Pearl is intended to be served through the @bitgo/wasm-utxo path, matching the wasm-only profile already used by ims-utxo.

5 files, 58 insertions.

Chain Type

UTXO — Taproot-only (BIP-340 Schnorr, BIP-341 script-path with a NUMS internal key). Pearl is a btcd fork.

@bitgo/wasm-utxo is authoritative on script-type support and restricts Pearl to Taproot:

btc   -> [ p2sh, p2shP2wsh, p2wsh, p2trLegacy, p2trMusig2 ]
ltc   -> [ p2sh, p2shP2wsh, p2wsh ]
pearl -> [ p2trLegacy, p2trMusig2 ]

Coin Codes & Tickers

Variant	Coin code	Ticker
Mainnet	pearl	PEARL
Testnet	tpearl	TPEARL

Names match @bitgo/wasm-utxo (coinNames: [..., "pearl", "tpearl"]) and indexer-utxo (CoinSymbol.pearl / CoinSymbol.tpearl).

Network Parameters

Parameter	Mainnet	Testnet
Bech32m HRP	prl	tprl
BIP-44 coin type	808276	1
Derivation path	m/86'/808276'/0'	m/86'/1'/0'
Decimals	8	8

Changes

File	Change
src/base.ts	CoinFamily.PEARL, UnderlyingAsset.PEARL
src/networks.ts	Pearl / PearlTestnet classes + Networks.main/Networks.test entries
src/utxo.ts	pearl / tpearl coin entries with PEARL_FEATURES
test/unit/fixtures/expectedColdFeatures.ts	both names added to justMultiSig
test/unit/coins.ts	pearl / tpearl case in the Distributed Custody Features suite

Coin features

PEARL_FEATURES is UtxoCoin.DEFAULT_FEATURES plus BULK_TRANSACTION and DISTRIBUTED_CUSTODY, matching the onboarding TDD (§9, Phase 6 PR 1). MULTISIG comes from DEFAULT_FEATURES rather than being listed again.

DISTRIBUTED_CUSTODY is deliberate, not copied from BTC by accident. Pearl is currently the only non-BTC chain carrying it — the existing holders are btc and its testnet/OFC variants — which is consistent with the TDD's premise (§4, "Why BTC is the Template"): P2TR, BIP-340 Schnorr and BIP-341 script-path are implemented for BTC only, so Pearl is modelled on BTC rather than on the other UTXO forks. test/unit/coins.ts now pins the flag for both names so it cannot regress silently.

Both names share one PEARL_FEATURES array. The TDD lists BULK_TRANSACTION for mainnet only, but sharing matches how bch/tbch, ltc/tltc and doge/tdoge are defined here, and keeping testnet at parity avoids a weaker test surface than mainnet.

On utxolibName

UtxoNetwork requires a utxolibName: string, so the classes set 'pearl' / 'tpearl' — the wasm CoinNames. With no utxo-lib network registered, these do not resolve to a utxolib.networks entry. That is intentional under the wasm-only approach, and the one structural consequence is noted below.

Verification

Module	Result
statics	32181 passing
utxo-lib	4249 passing
utxo-core	239 passing
abstract-utxo	1545 passing
utxo-bin	237 passing

All build clean (statics, utxo-lib, utxo-core, abstract-utxo, utxo-bin, sdk-core); prettier clean. Rebased onto current master.

Known consequence of the wasm-only approach

Nothing in this PR is blocked, but for the record: sdk-core's abstractUtxoCoinUtil.ts resolves statics' utxolibName into a utxo-lib network —

const network = utxolib.networks[coin.network.utxolibName as utxolib.NetworkName];

— in both getUtxoCoinScriptTypes2Of3() and getUtxoCoinScriptTypesForWalletType(). For Pearl that yields undefined and then throws TypeError: invalid network.

Not reachable today: no SDK coin class exists for Pearl, and the sdk-core tests covering those functions use a hardcoded coin list (btc, ltc, doge) rather than enumerating statics. It becomes reachable when the coin class lands, so those two functions need a wasm-backed path (or a Pearl guard) before Pearl is wired into wallet/address flows.

The good news for that follow-up: abstract-utxo is already almost entirely wasm-backed — 37 files import @bitgo/wasm-utxo, and the only 3 mentioning utxolib are a deprecation comment in abstractUtxoCoin.ts ("will be removed when we drop support for utxolib"), a comment in unspent.ts, and BTC-specific inscriptionBuilder.ts. Coin classes carry a name, not a Network, so a wasm-only Pearl coin class looks feasible without reintroducing utxo-lib.

Pull request overview

This PR introduces Pearl (pearl / tpearl) as a recognized UTXO network across BitGoJS’ statics + UTXO stack (statics, utxo-lib, utxo-core, utxo-bin, abstract-utxo tests), including Taproot-only wallet script-type enforcement to match @bitgo/wasm-utxo behavior.

Changes:

• Adds Pearl network definitions (mainnet/testnet) and detection helpers in @bitgo/utxo-lib, including Taproot-only script-type gating in outputScripts.isSupportedScriptType.
• Registers Pearl coin metadata in @bitgo/statics (family/asset/network/utxo coin entries + expectedColdFeatures).
• Updates dust threshold logic, CLI network parsing order, tests, and extensive address/PSBT fixtures; bumps @bitgo/wasm-utxo to ^4.27.0 across affected modules.

remove utxo-lib changes

[manojkumar138]

@OttoAllmendinger that all matches what's here now — this PR touches modules/statics only:

Your note	Status in this PR
no descriptors	0 files (utxo-descriptors never touched)
no ordinals	0 files (utxo-ord)
utxo-core does not need support	0 files — dust-policy change dropped
skip utxo-bin	0 files — networkOrder change dropped
just the basic fixed-script surface in abstract-utxo	0 files here; that's the next PR

So nothing to undo. The utxo-core and utxo-bin changes only existed because they referenced utxolib.networks.pearl, so they went out with the utxo-lib network.

Scoping the follow-up to your last point — basic fixed-script wallet surface in abstract-utxo, nothing else:

• names.ts — register pearl / tpearl
• impl/pearl/ — Prl / Tprl classes, taproot-only so exposing just p2tr / p2trMusig2 rather than inheriting AbstractUtxoCoin's defaults
• the two sdk-core abstractUtxoCoinUtil.ts helpers that resolve utxolibName into a utxo-lib network and would throw TypeError: invalid network for Pearl

No descriptors, no ordinals, no utxo-core, no utxo-bin, no inscriptionBuilder.

I'll hold off until this one merges so the statics entry exists first — shout if you'd rather I stack it on this branch now.

Code Review - Pearl (PEARL) Integration

Todo List:

• Review base configuration changes (modules/statics/src/base.ts)
• Review network definitions (modules/statics/src/networks.ts)
• Review UTXO coin entries (modules/statics/src/utxo.ts)
• Review test fixtures (modules/statics/test/unit/fixtures/expectedColdFeatures.ts)
• Validate Pearl specifications against PR requirements
• Check for code quality issues and best practices
• Provide final review summary

✅ Review Complete - Pearl Integration Analysis

Status: ⚠️ APPROVED WITH MINOR ISSUE

This statics-only PR properly implements Pearl cryptocurrency integration with 4 files and 48 insertions. The implementation follows BitGo patterns correctly, but there's one code quality issue to address:

🐛 Code Quality Issue

modules/statics/src/utxo.ts:148 - Duplicate MULTISIG Feature

const PEARL_FEATURES = [
  ...UtxoCoin.DEFAULT_FEATURES,  // Already includes CoinFeature.MULTISIG (line 27)
  CoinFeature.MULTISIG,          // ❌ Duplicate - should be removed
  CoinFeature.BULK_TRANSACTION,
  CoinFeature.DISTRIBUTED_CUSTODY,
];

UtxoCoin.DEFAULT_FEATURES already includes CoinFeature.MULTISIG at line 27. Adding it again creates a duplicate in the features array, which could cause issues with equality checks or serialization.

Fix: Remove the duplicate CoinFeature.MULTISIG line from PEARL_FEATURES.

✅ What Works Well

1. Base Configuration (modules/statics/src/base.ts) ✅

• Pearl coin family properly added to CoinFamily enum (line 113)
• Pearl underlying asset properly added to UnderlyingAsset enum (line 1688)
• Alphabetical ordering maintained correctly

2. Network Classes (modules/statics/src/networks.ts) ✅

• Pearl mainnet (Pearl) and testnet (PearlTestnet) classes properly implemented
• Correct UtxoNetwork interface implementation
• Networks properly registered in Networks.main.pearl and Networks.test.pearl
• explorerUrl = undefined is appropriate for new network
• utxolibName values ('pearl'/'tpearl') match wasm CoinNames as intended

3. UTXO Coin Definitions (modules/statics/src/utxo.ts) ✅ (except duplicate feature)

• Pearl mainnet entry (lines 329-339):
  • UUID: 4518a5b9-00d3-476e-bc40-d3f87eb82250 ✅
  • Name: pearl / Display: Pearl ✅
  • Network: Networks.main.pearl ✅
  • Asset: UnderlyingAsset.PEARL ✅
  • Suffix: PEARL ✅
• Pearl testnet entry (lines 340-350):
  • UUID: 5d88723a-7e86-43c7-9fb1-f4cee7abc48f ✅
  • Name: tpearl / Display: Testnet Pearl ✅
  • Network: Networks.test.pearl ✅
  • Suffix: TPEARL ✅
• Feature set includes appropriate capabilities:
  • BULK_TRANSACTION ✅
  • DISTRIBUTED_CUSTODY ✅
  • All default UTXO features ✅

4. Test Fixtures (expectedColdFeatures.ts) ✅

• pearl added to justMultiSig array (line 36)
• tpearl added to justMultiSig array (line 57)
• Proper alphabetical placement maintained

🎯 Validation Against Requirements

✅ Taproot-only focus: Confirmed by PR description and wasm-utxo integration
✅ Statics-only scope: No utxo-lib changes as requested by @OttoAllmendinger
✅ Naming consistency: pearl/tpearl matches wasm CoinNames and indexer-utxo symbols
✅ Feature set: Appropriate features for multisig, bulk transactions, and distributed custody
✅ Network parameters: Uses Bitcoin-compatible base unit and standard UTXO patterns

📋 Minor Observations

1. Wasm-only approach: The utxolibName values point to wasm coin names, not utxo-lib networks (as intended). The PR correctly notes this will require sdk-core adjustments later.

2. Missing explorer: explorerUrl = undefined is appropriate for a new network without public explorers yet.

🚀 Recommendation

APPROVED after fixing the duplicate CoinFeature.MULTISIG issue. This is a clean, well-structured integration that properly follows BitGo's statics patterns and sets up Pearl for the wasm-utxo path as intended.

Job run

[manojkumar138]

Both review points addressed in 3733692798 — thanks for the thorough pass.

1. Duplicate CoinFeature.MULTISIG (raised by both Claude and Copilot) — removed. It wasn't theoretical; the duplicate reached the shipped coin:

before: total features: 13 | duplicates: [ 'multisig' ]   (MULTISIG count: 2)
after:  total features: 12 | duplicates: none

I checked the sibling arrays (BCH_, BTC_, LTC_, DOGE_, DASH_, ZEC_FEATURES) — none re-add MULTISIG, so it was my oversight rather than an existing pattern. multisig, bulk-transaction and distributedCustody all remain on both names.

2. utxolibName documentation (Copilot) — added a block comment above both Pearl network classes plus a doc comment on each field, stating that the value is a wasm-utxo CoinName, that Pearl is deliberately unregistered in utxo-lib, and that resolving it through utxolib.networks[...] yields undefined and throws TypeError: invalid network.

On your minor observations: agreed on both. explorerUrl = undefined is deliberate — no public Pearl explorer yet. And yes, the sdk-core adjustment is tracked for the abstract-utxo follow-up; specifically getUtxoCoinScriptTypes2Of3() and getUtxoCoinScriptTypesForWalletType() in abstractUtxoCoinUtil.ts, which are the two call sites performing that lookup.

statics builds clean, 32180 passing, prettier clean. Still 4 files.

Code Review - Pearl (PEARL) Integration Re-review

Todo List:

• Review current state of changed files
• Verify duplicate MULTISIG feature fix
• Check documentation improvements for utxolibName
• Look for any remaining code quality issues
• Provide final review assessment

✅ Re-Review Complete - All Issues Resolved

Status: ✅ APPROVED

This re-review confirms that all previously identified issues have been properly addressed in the latest commits. The Pearl cryptocurrency integration is now clean and ready for merge.

🎯 Verified Fixes

1. Duplicate MULTISIG Feature Fixed ✅

• Previous Issue: PEARL_FEATURES included both ...UtxoCoin.DEFAULT_FEATURES (which contains CoinFeature.MULTISIG) and an explicit CoinFeature.MULTISIG
• Fix Verified: modules/statics/src/utxo.ts:146 now correctly shows:

  const PEARL_FEATURES = [...UtxoCoin.DEFAULT_FEATURES, CoinFeature.BULK_TRANSACTION, CoinFeature.DISTRIBUTED_CUSTODY];

• The duplicate CoinFeature.MULTISIG has been removed, eliminating the array duplication issue

2. Documentation Improvements Added ✅

• Previous Issue: utxolibName values needed clarification about wasm-only approach
• Fix Verified: Comprehensive documentation added in modules/statics/src/networks.ts:1434-1442:
  • Block comment explains Pearl is wasm-utxo only and NOT registered in utxo-lib
  • Warns that utxolib.networks[...] yields undefined and throws TypeError: invalid network
  • Individual JSDoc comments on each utxolibName field (lines 1446, 1454) reference the explanation

✅ Code Quality Assessment

Overall Implementation: The Pearl integration is well-structured and follows BitGo patterns correctly:

1. Base Configuration (modules/statics/src/base.ts) ✅

   • CoinFamily.PEARL added in alphabetical order (line 113)
   • UnderlyingAsset.PEARL added in alphabetical order (line 1688)

2. Network Classes (modules/statics/src/networks.ts) ✅

   • Pearl mainnet and testnet classes properly implement UtxoNetwork
   • Network registration in both Networks.main.pearl and Networks.test.pearl
   • explorerUrl = undefined is appropriate for new network

3. UTXO Coin Definitions (modules/statics/src/utxo.ts) ✅

   • Pearl mainnet entry (lines 324-334): proper UUID, name, network, asset, suffix
   • Pearl testnet entry (lines 335-345): proper UUID, name, network, asset, suffix
   • Feature set appropriately includes BULK_TRANSACTION and DISTRIBUTED_CUSTODY
   • No duplicate features after fix

4. Test Fixtures (expectedColdFeatures.ts) ✅

• Same as the mainnet entry: the explicit '' prefix and TPEARL suffix are redundant because utxo() already defaults to prefix='' and suffix=name.toUpperCase() (so tpearl -> TPEARL). Relying on defaults keeps these entries consistent with the rest of the file.

Code Review - Pearl (PEARL) Integration Re-review

Todo List:

• Review current state of changed files
• Verify duplicate MULTISIG feature fix
• Check documentation improvements for utxolibName
• Look for any remaining code quality issues
• Provide final review assessment

✅ Re-Review Complete - All Issues Resolved

Status: ✅ APPROVED

This re-review confirms that all previously identified issues have been properly addressed in the latest commits. The Pearl cryptocurrency integration is now clean and ready for merge.

🎯 Verified Fixes

1. Duplicate MULTISIG Feature Fixed ✅

• Previous Issue: PEARL_FEATURES included both ...UtxoCoin.DEFAULT_FEATURES (which contains CoinFeature.MULTISIG) and an explicit CoinFeature.MULTISIG
• Fix Verified: modules/statics/src/utxo.ts:146 now correctly shows:

  const PEARL_FEATURES = [...UtxoCoin.DEFAULT_FEATURES, CoinFeature.BULK_TRANSACTION, CoinFeature.DISTRIBUTED_CUSTODY];

• The duplicate CoinFeature.MULTISIG has been removed, eliminating the array duplication issue

2. Documentation Improvements Added ✅

• Previous Issue: utxolibName values needed clarification about wasm-only approach
• Fix Verified: Comprehensive documentation added in modules/statics/src/networks.ts:1434-1442:
  • Block comment explains Pearl is wasm-utxo only and NOT registered in utxo-lib
  • Warns that utxolib.networks[...] yields undefined and throws TypeError: invalid network
  • Individual JSDoc comments on each utxolibName field (lines 1446, 1454) reference the explanation

✅ Code Quality Assessment

Overall Implementation: The Pearl integration is well-structured and follows BitGo patterns correctly:

1. Base Configuration (modules/statics/src/base.ts) ✅

   • CoinFamily.PEARL added in alphabetical order (line 113)
   • UnderlyingAsset.PEARL added in alphabetical order (line 1688)

2. Network Classes (modules/statics/src/networks.ts) ✅

   • Pearl mainnet and testnet classes properly implement UtxoNetwork
   • Network registration in both Networks.main.pearl and Networks.test.pearl
   • explorerUrl = undefined is appropriate for new network

3. UTXO Coin Definitions (modules/statics/src/utxo.ts) ✅

   • Pearl mainnet entry (lines 324-334): proper UUID, name, network, asset, suffix
   • Pearl testnet entry (lines 335-345): proper UUID, name, network, asset, suffix
   • Feature set appropriately includes BULK_TRANSACTION and DISTRIBUTED_CUSTODY
   • No duplicate features after fix

4. Test Fixtures (expectedColdFeatures.ts) ✅

   • pearl and tpearl properly added to justMultiSig arrays
   • Alphabetical ordering maintained

📊 PR Statistics Confirmed

• Scope: Statics-only as requested (4 files, 54 insertions, 0 deletions)
• No utxo-lib changes: Correctly removed per @OttoAllmendinger's feedback
• Clean implementation: No unnecessary files or code
