Developers merged pull request #28264 containing the upstream software fix into Reth's GitHub code repository

Security firm Blockaid confirmed the Reth state-root calculation flaw was a code calculation error rather than an active exploit, with no stolen funds reported

Reth's block-building software used vulnerable calculation code across networks built with Optimism's OP Stack, creating shared defect risks across multiple interconnected Ethereum layer-2 blockchains

Frax Finance reported on November 5, 2026, that its smart contracts and user assets remained secure despite LayerZero's temporary cross-chain route suspensions

Georgios Konstantopoulos, chief technology officer at Paradigm, said a flaw in execution client Reth's legacy state-root calculation system could return incorrect cryptographic hashes when processing specific smart contract storage configurations

Paradigm CTO Georgios Konstantopoulos clarified that Base and other OP Stack networks avoided faulty withdrawal risks because ecosystem bridge mechanisms rely on separate transaction receipts or multisignature authorization

Security firm Blockaid warned that blockchain nodes still running unpatched Reth software code could freeze up or return faulty state proofs

The Binance attackers moved 486,970 Solana tokens worth roughly $46.4 million within one hour using Relay Protocol to execute cross-chain swaps into Bitcoin.

The stolen Premia Labs assets were bridged from Arbitrum to Ethereum before being converted into Bitcoin using cross-chain platforms Chainflip and NEAR Intents.

Blockchain security researchers noted that Chainflip and NEAR Intents limit traceability of transferred funds, though neither service was identified as the source of Premia Labs' vulnerability.

Cross-chain orchestration platforms Chainflip and NEAR Intents allow users to swap cryptocurrency across separate blockchain networks without conventional centralized exchanges.

Hackers of the 2026 Binance exploit routed stolen TRX and Solana through THORChain to convert them into Bitcoin and Ether

Base said Denim blocks B20 token mints, transfers, and seizures targeted at a token contract's own address to prevent permanent asset locking

Analyst SomaXBT estimated that transfers of funds stolen in the October 29, 2026 Binance hack included nearly $48 million through Relay, $44 million through THORChain, $32.1 million through Chainflip, and $16 million through Symbiosis

Analyst SomaXBT estimated that around $242 million of funds stolen in the October 29, 2026 Binance hack moved via the Tron blockchain in two days, including $140 million transferred through cross-chain services like Relay, THORChain, Chainflip, and Symbiosis

Blockchain researcher Taylor Monahan argued that THORChain network operators possess the technical ability to halt suspicious transaction routes to prevent illicit cross-chain flows

THORChain maintained trading halts or warnings on BNB Smart Chain, Cosmos Hub, and Solana as of November 3, 2026

THORChain restored cross-chain trading and transaction signing on Bitcoin, Ethereum, Bitcoin Cash, Dogecoin, Litecoin, Tron, and Zcash by November 3, 2026, following a weekend halt triggered by an Ethereum reorg refund bug
