From 1208c6386c36cb932809b426019618a3c6663ca7 Mon Sep 17 00:00:00 2001 From: Prajwal U Date: Mon, 6 Jul 2026 23:46:37 +0530 Subject: [PATCH] feat(sdk-coin-xlm): add accountConfig, authorizeTrustline, clawback ops ## Problem XLM was missing support for three critical transaction types required for account management: setOptions (accountConfig), setTrustLineFlags (authorizeTrustline), and clawback. These operations enable issuers to configure account flags, authorize trustlines, and reclaim assets respectively. Wallet Platform cannot build or verify these transaction types without implementation. ## Goal Add complete support for accountConfig, authorizeTrustline, and clawback transaction types in the XLM coin implementation, including parsing, verification, and explanation logic. Ensure non-payment intents inject empty recipients to prevent platform from synthesizing default payment operations. ## Fix - Added TypeScript interfaces: AccountFlags, TrustlineAuthEntry, ClawbackEntry, and verify-param types for each operation - Extended TransactionOperation interface with fields for setOptions (setFlags/clearFlags), setTrustLineFlags (trustor/authorized), and clawback (from/amount) - Updated getExtraPrebuildParams to return empty recipients for non-payment types (accountConfig, authorizeTrustline, clawback) - Implemented three verify methods: verifyAccountConfigOperations, verifyAuthorizeTrustlineOperations, verifyClawbackOperations - verifyAccountConfigOperations rejects transactions with more than one setOptions operation to prevent silently unverified ops - Replaced unsafe 'as unknown as' casts with typed type guard functions (isAccountConfigVerifyParams, isAuthorizeTrustlineVerifyParams, isClawbackVerifyParams) that validate required field shapes at runtime - Updated verifyTransaction to dispatch via type guards - Updated explainTransaction to parse Stellar setOptions, setTrustLineFlags, and clawback operations into the new operation types - Extended BuildParams codec with top-level fields: flags, clearFlags, trustlineAuths, clawbacks so params are forwarded in prebuild API requests ## Testing - Added 18 test cases covering getExtraPrebuildParams for all three new types plus payment fallback - Added 16 verifyTransaction tests covering successful verifications and error cases (count mismatch, field mismatch, missing operations, multiple setOptions, type guard rejection for missing required arrays) - Added 3 explainTransaction tests verifying operation parsing from Stellar XDR - All tests use Stellar TESTNET and construct valid XDR transactions Ticket: CSHLD-1089 Co-Authored-By: Claude Sonnet 4.6 --- modules/sdk-coin-xlm/src/xlm.ts | 201 +++++++++- modules/sdk-coin-xlm/test/unit/xlm.ts | 368 ++++++++++++++++++ .../sdk-core/src/bitgo/wallet/BuildParams.ts | 4 + 3 files changed, 572 insertions(+), 1 deletion(-) diff --git a/modules/sdk-coin-xlm/src/xlm.ts b/modules/sdk-coin-xlm/src/xlm.ts index 02d56a71c7..e2db57090c 100644 --- a/modules/sdk-coin-xlm/src/xlm.ts +++ b/modules/sdk-coin-xlm/src/xlm.ts @@ -124,6 +124,15 @@ interface TransactionOperation { coin: string;
