ERC-8478 is a draft Ethereum standard that binds the x402 payTo address to an ERC-8004 agent's identity, to stop payee redirection by a hijacked domain, proxy or injected tool result. A payTo must equal the agentWallet or carry an EIP-712 delegation signed by it, and the origin must be listed in the registration file.

How the Binance hack happened on-chain on Ethereum

Protos analysis of how the Binance hack played out on Ethereum. The attacker deployed a sweeper contract and sent 50 EIP-7702 authorizations for the Binance 14 hot wallet, signed with its key and using varied nonces to match the wallet's changing count. Other wallets and EVM chains used plain transfers. Binance later removed the delegation, and about $2.4 billion in funds was frozen or blacklisted.

ChainSecurity research showed EIP-8037 and EIP-8038 gas repricing can let a contract's failure path succeed where it used to revert, for example a fresh storage write costing 110,020 gas instead of 22,100. This enables "insufficient gas griefing", and ChainSecurity found 13 real-world cases.

Ethereum Delays Glamsterdam Testnet Fork Over Gas Security Flaws

Ethereum developers postponed the Glamsterdam hard fork on the Hoodi testnet (due 26 October 2026) after auditor ChainSecurity reported that the gas changes in EIP-8037 and EIP-8038 break assumptions in existing contracts. Gas can be refilled after a failed call and repricing alters call costs, so failure paths that used to revert can now complete, undermining insufficient gas griefing protections. ChainSecurity found 13 real-world examples and is in responsible disclosure.

Ethereum delays Glamsterdam test after security devs flag risk to existing contracts

Ethereum developers cancelled the Glamsterdam activation on the Hoodi testnet, planned for 26 October 2026, after ChainSecurity's 13 October analysis of EIP-8037 and EIP-8038. The gas-accounting changes can restore gas after a reverted state change, letting contracts finish failure-handling code that used to run out of gas. In the other direction, a new storage slot could cost 110,020 gas instead of 22,100. No production protocol is shown to be exploitable.

Crypto exchange CoinDCX ‘lying’ about $16M hack, say blockchain investigators

Protos reports that on-chain investigators, including Darcy of Salus, ZachXBT and SpecterAnalyst, say CoinDCX misattributed about $16M in outflows from compromised wallets. CoinDCX says the addresses were created in January 2025, compromised in July 2025, and that a sweeping process failed.

PQ-Vault: Provably Quantum-Safe Asset Custody for Unmodified Ethereum

PQ-Vault is a custody design for unmodified Ethereum against quantum key recovery. It combines a quantum-safe vault contract, a proof-of-stake sidechain with compact certificates, and an optimistic dispute protocol. The paper proves that compact certificates with classically chosen parameters fall from 128 to about 60 bits against quantum attackers, and bounds a seed-update stake-steering attack. For 65,536 validators a certificate is 0.8 MB and verifies in about 20 ms, and the vault accepts a checkpoint for about 420,000 gas.

Satoshi-era bitcoin faces a bigger quantum threat after Google’s new Willow breakthrough

CoinDesk reports Google's Science paper showing its Willow chip prepares "magic states" with about 40x fewer errors (about 99.99% fidelity, but only about 8% of attempts survive post-selection) using a method called cultivation. It explains why this lowers one hardware bottleneck for a Shor's-algorithm attack on Bitcoin's ECDSA keys, but does not make an attack 40x cheaper. It also separates coins with permanently exposed public keys (early Satoshi-era outputs, which an offline attacker can target) from hash-hidden keys, where the attacker must race the spend. The article cites Google's March estimate of under 500,000 physical qubits and about 500,000 reliable magic states per second for a roughly nine-minute attack.

ERC-8443: Quantum Bridge Shield

Draft ERC from Quantova Inc proposing a "Quantum Bridge Shield" for Ethereum bridges. A committee signs the Merkle root of each message batch with RFC 8554 LMS hash-based signatures instead of ECDSA/BLS keys that Shor's algorithm can break. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain, chain, guard and epoch, and applies a 60-second delay. The post gives gas costs (LMS W4 height-10 verification about 205k gas, a LayerZero packet 128,683 gas, worst-case rotation 12.44M gas under the EIP-7825 cap) and cites a NioLabs assessment with no critical or high findings.

A payment consuming hundreds of crafted order-book offers made the buyer's owed sum wrap around to a tiny value while sellers were paid in full, minting XRP. The built-in "no XRP created" invariant check used the same flawed arithmetic and missed it. The fix shipped in 3.4.1 on Sept. 25, bypassing the usual amendment vote and two-week wait for the first time, so the open-source patch would not expose a live exploit.

XRP Ledger patches decade-old bug that could have minted trillions of XRP

The Block reports on the XRP Ledger disclosure of a critical bug that had been in the payment engine since 2015. Order-book offer totals had no overflow check, so a single payment consuming a few hundred crafted offers could wrap the sum and mint spendable XRP past the 100B cap. Veria Labs' AI agent found it and built a working exploit, and RippleX shipped the fix in xrpld 3.4.1 on Sept. 25, bypassing the usual amendment vote to avoid tipping off attackers. The article also covers the $250K bounty, a separate Batch bug, and the closed-source-release criticism.

How Zcash Plans to Hide Your Keys From AI and Quantum Attacks

Decrypt reports that Zakura, which builds a Zcash full node, expects post-quantum signature opcodes in Zcash in January, to enable hash-based signatures for transparent pools. The plan rotates to a fresh transparent address after every transaction so public keys stay hidden, and adds a WOTS hash-based backup signature. Private information retrieval, shipping this week in the Vizor wallet, stops servers from linking the rotated addresses. It follows Justin Drake's "bunker mode" warning that AI-driven math could break ECDSA. The plan covers only transparent payments, and no activation date has been confirmed.

An XRP Ledger security bug could have created 18.45 trillion XRP

Reports a decade-old integer overflow in the XRP Ledger payment engine's DEX offer-crossing code (added 2015). A single transaction across hundreds of seeded accounts could have minted about 18.45 trillion XRP, because the overflowed total understated what the buyer paid and the mint-check safeguard used the same wrong total. Veria AI found it on 2026-09-21 and reported it through the bug bounty. RippleX reproduced it on a standalone server and shipped xrpld 3.4.1 on 2026-09-25 as binaries only, with no patch source. RippleX's Mayukha Vadari warns that AI makes silent critical patches easy to reverse engineer, and the withheld source drew open-source criticism.

XRP Ledger patched decade-old bug that could create billions of dollars in XRP from nothing

CoinDesk reports that researcher Cayden Liao and Veria AI found a flaw, believed to date to 2015, in the XRP Ledger's built-in exchange. Hundreds of crossed offers made the total XRP owed too large for the software to count correctly. The buyer was charged almost nothing while the sellers were paid in full, so XRP was created from nothing. The bug slipped past the ledger's post-transaction no-new-XRP invariant check, which relied on the miscounted total, and past per-account receive limits, because the XRP was spread across hundreds of accounts. RippleX reproduced it on a standalone server and fixed it in xrpld 3.4.1 on Sept. 25 without disclosing the cause. It found no evidence of exploitation on public networks.

Ledger says Southeast Asia reseller linked to $86M draining

Protos reports that Ledger users who bought devices from the Malaysian/Southeast Asian reseller CryptoBilis have been drained of an estimated $72M to over $86M, per on-chain tracing by analysts Specter and Tanuki42. Ledger told CryptoBilis to pause sales and shipments, and advised buyers from the past 90 days not to set up their devices, or to move funds to a new signer if they already had. The article cites Mark Karpelès on reseller wallets found tampered with and implanted with spyware, and Taylor Monahan warning that there is no sign of a zero-day and that panic migration invites phishing and fake-ad drainers.

Ledger is investigating fund losses among Southeast Asian customers who bought hardware wallets from the reseller CryptoBilis. It has asked the reseller to pause sales and told buyers from the last 90 days not to set up their devices, or to move funds to a new device with a fresh seed phrase. Onchain investigator Specter traced about $86–87M in thefts across Ethereum, Tron and Bitcoin. Ledger has confirmed neither the figure nor the cause, though pre-compromised devices shipped with an attacker-known recovery phrase are the suspected mechanism.

UK Targets Cryptomus and TokenSpot in New Russia Sanctions Package

The UK FCDO sanctioned crypto exchange Cryptomus via its Vancouver registered owner Xeltox Enterprises and linked platform Heleket, Kyrgyz firms TokenSpot and Tsunami Payments, and payment processor Processing KG which operates VexPay and is owned by Kyrgyzstan's Ministry of Finance, plus its director Ulan Bukabaev, for allegedly helping Russia evade financial sanctions. Two of the designated entities reportedly processed transactions for the Kremlin backed A7 illicit finance network, which claims to have moved over 90 billion dollars last year, roughly half of Russia's annual military spending. The 38 target package, which also hit oil producers Zarubezhneft and INK Capital and 12 shadow fleet tankers, follows earlier UK and EU action against Justin Sun's HTX and extends a pattern of Western sanctions targeting crypto rails used for Russia sanctions evasion.

Zcash developers set January target for quantum-resistant payments after ‘bunker mode’ scare

Zcash developer Roman Akhtariev, writing for the Zakura client team, announced a January target for adding post-quantum signature opcodes supporting hash-based signatures to Zcash's transparent (public) payment pool, which holds about 70% of issued ZEC. The move responds to Ethereum researcher Justin Drake's "bunker mode" warning that AI could soon break the elliptic-curve math behind Bitcoin and Ethereum wallet keys. Zakura has also built a private-information-retrieval balance-lookup tool, now experimentally available in the Vizor wallet, that lets a wallet check address balances without revealing to the server which addresses are linked, separate from the shielded-pool quantum-recovery work still needed to defend against store-now-decrypt-later attacks.

Understanding Verification Vulnerabilities in Cross-chain Bridges: An Empirical Study

First systematic empirical study of Cross-chain Verification Vulnerabilities (CVVs) in bridge smart contracts, such as flawed validation of state proofs, message sender identities and signatures. From 588 audit reports across 36 bridge projects it derives 11 CVV patterns in 5 categories and builds a dataset of 830 instances across 786 contract files, mapped to reports, source versions and pattern labels. Existing tools cover few CVV patterns, and only two of four tested LLMs beat a 29.3% Macro-F1 constant baseline (best 51.2%), which motivates detectors built for cross-chain verification semantics.

XRP Ledger adds new controls for banks, stablecoins and tokenized funds

CoinDesk reports that the XRP Ledger activated PermissionDelegationV1_1 on Oct. 8, letting account owners authorize helper accounts to perform limited actions (e.g., customer approval, payments) without exposing primary signing keys, each helper limited to 10 permissions with no spending cap. The article flags two live security issues: the PaymentBurn permission, meant to let a helper destroy issued tokens, can under certain conditions let that helper mint new tokens instead, so operators are told not to delegate it until a fix (currently at 27 of 35 validator votes) activates; separately, a bug found Oct. 8 causes some servers to drop online validators from their consensus vote count after a routine key rotation, which can make an upgrade proposal appear closer to the 80% threshold than it actually is.

Hybrid post-quantum stealth addresses (ERC-5564 schemeId 3)

A draft ERC proposing schemeId 3 for ERC-5564 stealth addresses, combining an ML-KEM-768 encapsulation with a secp256k1 ECDH secret so that future quantum computers cannot retroactively deanonymize recipients from the public announcement log, while spending stays classical secp256k1 (and thus still quantum-vulnerable once spent). The post, with a linked reference implementation, test vectors and gas harness, details the key/meta-address format, the payment-secret combiner (hashing both shared secrets and ciphertexts for IND-CCA), the view-tag derivation ordering to avoid quantum tag-narrowing, measured gas cost (111,330 gas per payment on Prague), and open questions around ANO-CCA proofs for standardized ML-KEM, NIST SP 800-56C combiner approval, and downgrade-attack handling when a recipient registers under both schemeId 1 and 3.

A draft Ethereum ERC (ERC-8441) proposes schemeId 3 for ERC-5564 stealth addresses, combining an ML-KEM-768 encapsulation with a secp256k1 ECDH secret so that quantum adversaries who later break discrete log still cannot deanonymize who was paid in past public announcement logs, protecting against harvest-now-decrypt-later attacks. Spending remains classical secp256k1 and unprotected once quantum computers exist; the authors flag open issues including a documented downgrade attack (recipients registered under both scheme 1 and 3 can still be paid without PQ protection), the lack of a formal ANO-CCA proof for standardized ML-KEM, and a non-NIST-approved secret combiner. It reuses the existing ERC-5564 announcer and ERC-6538 registry with no contract changes, costing 111,330 gas per payment.

‘Shielded Bitcoin

Galaxy Research newsletter piece covering "Shielded Bitcoin," a paper by [[alloc] init] researchers Clara Shikhelman, Mikhail Komarov, and Aleksei Moskvin proposing a Zcash-style shielded pool (encrypted notes, public nullifiers, zero-knowledge proofs) run as a Bitcoin L1 metaprotocol via OP_RETURN envelopes, with peg-in/peg-out deliberately left to a future "PIPEs v2" paper. The article's security-relevant angle flags that novel ZK circuits need battle-testing — citing Zcash's own Orchard Pool soundness bug that survived professional audits for four years before being fixed in the Ironwood upgrade — and that bridge/peg mechanisms (the likely weak point) have historically been the most exploited component in crypto, naming Ronin, Wormhole, Nomad, and KelpDAO.

💧 Looting of Liquid Sidechain Underscores Emerging Cyber Threat to Bitcoin

Galaxy Research breaks down the theft of 4,000 BTC (~$320m) from the Liquid Network, a Bitcoin sidechain run by the Liquid Federation. Attackers exploited a bug in the sidechain node code to artificially mint 4,000 L-BTC, then abused an auto-forward feature offered by federation member SideSwap to bypass peg-out address whitelisting and withdraw real BTC to the main chain; the self-described "white hats" returned 85% but held 15% hostage, negotiating with developer Blockstream via PGP-encrypted OP_RETURN messages and demanding a 10% bug-bounty payout. The piece also contrasts this with concurrent Coldcard and BTCPay Server incidents and speculates about AI-assisted vulnerability discovery.

Weekly Research Brief: Bitget Hack, AI Accord and SEC FAQs

Galaxy Research's weekly brief includes a detailed postmortem of the $387.5M Bitget hack: attackers exploited a zero-day in two unnamed third-party security products ("Product A"/"Product B") to obtain high-level internal credentials, inserted forged withdrawal commands into Bitget's wallet backend across 11 chains, then deleted the fraudulent commands — with Bitget attributing the attack to North Korean actors based on IP behavior and wallet overlaps found by Elliptic and TRM. The piece draws a direct parallel to the $1.5B Bybit/Lazarus heist (compromised Safe{Wallet} infrastructure rather than stolen keys) to argue that private-key cryptography is effectively solved and attackers now target the approval pipeline/intermediary services instead; it also covers the follow-on $3.8M NEAR Intents Omni-bridge exploit and THORChain's continued role laundering DPRK proceeds.

Buterin also flags that lattice-based post-quantum schemes, the basis of NIST's signature standard, could face similar AI-driven erosion, pushing Ethereum's long-term roadmap toward hash-based signatures instead. The piece grounds the warning in already-documented AI-assisted exploit discovery: a 5-year-old Coldcard hardware-wallet firmware bug drained over 1,367 BTC, BTCPay Server Lightning-node thefts, Core Lightning bugs surfaced via AI-generated audits, and Anthropic's demonstration of AI models writing working exploits against simulated DeFi contracts.
