From 467ff30d6ec0f3141d9b5f36ac338b0628de339d Mon Sep 17 00:00:00 2001 From: mrdanish26 Date: Wed, 29 Apr 2026 17:08:29 -0700 Subject: [PATCH 1/2] fix(sdk-core): bypass TSS recipient guard generically for staking intents MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BSC/BNB hot wallet staking breaks after WAL-375 SDK bump because the staking wallet calls signTransaction without txParams, and staking intentType strings were absent from the recipient bypass set. Instead of enumerating every staking intentType string (which drifts as new coins add staking support), detect staking intents generically via the presence of stakingRequestId on the intent — a required field on BaseStakeIntent in @bitgo/public-types that all staking intents inherit. Fix: - NO_RECIPIENT_TX_TYPES retains only the 8 non-staking ECDSA types - resolveEffectiveTxParams checks stakingRequestId as a generic staking signal; throws only if no recipients, not staking, and not an ECDSA no-recipient type - Keep intent.intentType fallback so txType propagates to downstream verifyTssTransaction callers - Revert verifyTssTransaction bypass list in abstractEthLikeNewCoins.ts back to 8 original ECDSA types - Remove stale verifyTssTransaction override from bsc.ts (parent handles) - Tests: updated makeTxRequest to accept stakingRequestId; realistic tests using delegate/stake + stakingRequestId; negative test confirms delegate without stakingRequestId still throws Refs: WAL-756 Co-Authored-By: Claude Sonnet 4.6 (1M context) TICKET: WAL-756 --- .../src/bitgo/utils/tss/recipientUtils.ts | 28 ++++++++-- .../unit/bitgo/utils/tss/recipientUtils.ts | 53 +++++++++++++++++-- 2 files changed, 72 insertions(+), 9 deletions(-) diff --git a/modules/sdk-core/src/bitgo/utils/tss/recipientUtils.ts b/modules/sdk-core/src/bitgo/utils/tss/recipientUtils.ts index 682228c4b0..499bea95bb 100644 --- a/modules/sdk-core/src/bitgo/utils/tss/recipientUtils.ts +++ b/modules/sdk-core/src/bitgo/utils/tss/recipientUtils.ts @@ -4,7 +4,8 @@ import { PopulatedIntent, TxRequest } from './baseTypes'; /** * Transaction types that legitimately carry no explicit recipients. - * verifyTransaction handles no-recipient validation for these internally. + * These are non-staking ECDSA types where verifyTransaction handles + * no-recipient validation internally. * Mirrors the bypass list in abstractEthLikeNewCoins.ts verifyTssTransaction. */ export const NO_RECIPIENT_TX_TYPES = new Set([ @@ -15,7 +16,7 @@ export const NO_RECIPIENT_TX_TYPES = new Set([ 'consolidate', 'bridgeFunds', 'enableToken', - 'customTx', // DeFi/WalletConnect smart contract interactions have no traditional recipients + 'customTx', ]); /** @@ -25,8 +26,13 @@ export const NO_RECIPIENT_TX_TYPES = new Set([ * (native amount = 0, so buildParams is empty).
