migration

Cryptocurrency exchange Coinbase stated that its custody holds about 5% of the total existing Bitcoin and urged Bitcoin developers to immediately address the threat of quantum computing. Coinbase pointed out that changes to Bitcoin consensus and ecological migration may take years and cannot wait until quantum computers capable of breaking signatures appear.Coinbase suggested adopting a flexible "container" design similar to BIP-360 to gradually replace quantum-resistant signature systems; it also proposed a phased implementation of a "1-of-2" scheme, allowing the same funds to be spent during the transition period using either traditional keys or quantum-resistant keys. This scheme also needs to be compatible with multi-party computation (MPC) key splitting mechanisms. Coinbase stated that dormant, lost, and Bitcoin held from the Satoshi era are separate governance issues, and any rescue mechanism itself must also possess quantum resistance. In January of this year, Coinbase established a quantum advisory council; in July, it joined the Bitcoin Security Alliance with BlackRock and Strategy, committing a total of $15 million for Bitcoin's quantum-resistant transformation.

According to CryptoQuant analyst nocoffeenobrain's monitoring, Bitcoin holdings aged 1-3 years and over 3 years showed signs of activity as early as the end of September, when the BTC price rose from the mid-$70,000s to the mid-$80,000s.Recently, Ledger was hacked, prompting a large number of users to migrate their assets to new signers and change their mnemonic phrases. It is expected that the 7-day moving average will further rise in the coming days. Analysts pointed out that similar patterns have occurred before—during the period from January to February this year, when BTC fell from the mid-$90,000s to the mid-$60,000s, and during the period from July to August when BTC fluctuated in the mid-$60,000s, both of the aforementioned holding age segments showed synchronized activity.

Coinbase released a technical discussion article on Bitcoin's Post-Quantum Readiness, stating that Bitcoin needs to proactively address the cryptographic risks posed by quantum computing in the future and recommends that the community begin relevant migration preparations as soon as possible.Coinbase believes that Bitcoin's quantum-resistant upgrade involves not only selecting new quantum-resistant signature algorithms but also considering factors such as block space limitations, full node validation capabilities, institutional custody needs, ordinary wallet compatibility, and solutions for handling funds that cannot be migrated. Bitcoin should consider introducing output structures that support quantum-resistant signatures and explore hybrid solutions, such as allowing the same funds to have both traditional ECDSA/Schnorr signatures and quantum-resistant signatures as authorization paths for a smooth transition.Additionally, Coinbase emphasizes that the quantum migration will take years, and the community should complete preparations before the threat of quantum computing truly emerges. For BTC funds that have not migrated for a long time, lost private keys, or exposed public keys, Coinbase believes that solutions should still be sought through governance and technical discussions.

The proposal for the activation of ENSv2 for Ethereum Name Service (ENS) states that after the official launch of ENSv2, new registrations for ENSv1 will cease, while existing .eth domain holders will not face a migration deadline and can continue to retain and use their registered domains.The proposal also arranges for ENS Labs to transfer its remaining management roles for ENSv2 to the ENS DAO, handing over the relevant management authority to the community.

The official NEAR public chain stated on X that cryptographic agility is a fundamental requirement of the blockchain industry, and the upgrade of signature schemes should become routine. NEAR accounts now support post-quantum ML-DSA signature schemes without the need to migrate assets.The NEAR core development team, Near One, is advancing NEP-655. This proposal involves commitment-based implicit accounts derived from the initial state hash, with assets located after that hash, without exposing public keys or key hashes on-chain. The related functionality has currently been launched on the testnet, with the mainnet planned for release in the coming weeks.For developers, the team is designing the NEAR Intents wallet contract to support custom signature extensions, including ML-DSA and hash-based schemes. For chains that cannot currently add post-quantum keys, the team is advancing the Q-day recovery registry on NEAR, allowing users to submit recovery keys in a rotatable hash format. NEAR claims that quantum computing factors were considered in its design back in 2018.

Uniswap's OP Stack Layer 2 network Unichain announced on X that it will migrate to OP Enterprise in preparation for native cross-chain interoperability of OP Stack.Unichain stated that after interoperability goes live, users will be able to transfer assets between OP Stack chains without the need for cross-chain bridges, with ETH being the first supported asset. The testnet migration is scheduled for October 13, and the mainnet migration is planned for late October.

On-chain options protocol Derive announced that Derive V3 has been launched, the migration has been successfully completed, and trading has resumed. The team stated that this rebuild aims to continue the growth of its on-chain options business, with custody located on Ethereum, margin and settlement using zero-knowledge proofs, and order matching latency below 1 millisecond.According to the announcement, V3 supports the launch of no-code vaults and charges fees, and funds can also be released through ETH and BTC risk offset. Related features also cover yields and lending for ETH, WBTC, HYPE, and USDC, and accelerate the onboarding of crypto assets with real-world assets. Developers can build applications on Derive with less configuration and earn fees.Derive stated that new markets, vaults, and partner integrations will be launched on this basis in the coming weeks. The project indicated that its on-chain options business has been operating for over 5 years.

The core development team of Solana, Anza developer Jacob Creech, stated that unlike some blockchains, Solana users do not need to urgently transfer assets due to AI-accelerated password cracking or quantum computing threats. He explained that Solana uses the Ed25519 signature algorithm, where the signing key is derived from a secret seed through hashing. Even if elliptic curve cryptography is cracked in the future, attackers cannot directly recover the original seed from it.Creech mentioned that theoretically, Solana could introduce a hash-based seed ownership proof through a network upgrade, allowing original holders to verify their identity and migrate to a more secure signing scheme. Anza has developed a related proof-of-concept prototype. He also emphasized that Solana is currently still secure and has a technical roadmap to address future cryptographic threats.

According to The Defiant, Onyx transferred 620 million XCN tokens. This transfer executed a migration proposal that Onyx had previously publicly promoted. After the transfer, only about 1.89 million XCN remained in its Ethereum treasury contract.This large transfer occurred at the same time Blockaid issued a vulnerability alert.

Polymarket's Vice President Josh stated on platform X that the team is fully developing a complete Central Limit Order Book (CLOB) based on Rust, as the current CLOB is the root cause of most issues on the platform.According to the plan, the complete order lifecycle process, including trading, settlement, on-chain interaction, indexer, and engine notifications, will be completed in the testing environment in October; in November, all production traffic will be mirrored to the new trading cluster, and results will be compared with the existing system. At the same time, testing permissions will be opened to market makers, and the migration switch plan will be locked in, with two complete drills to be completed before the official switch.Josh also mentioned that if progress goes smoothly, the new system will be officially released, and the migration is expected to require little or no changes for market makers and developers.

Binance will support the migration of Zilliqa (ZIL) from the Zilliqa mainnet to the ZILEVM network. Binance has suspended deposits and withdrawals for the Zilliqa mainnet on August 5, 2026, at 09:00. After the migration is complete, deposits and withdrawals through the ZILEVM network will be opened.

The official post from Switchboard Foundation Group (@SwitchboardFDN) announces the formal closure of the decentralized oracle protocol Switchboard, with all support ending on September 25, 2026.Switchboard stated that the widespread adoption of AI technology has reduced the pricing power of oracles, the bear market has compressed new chain budgets, and the trend of direct collaboration between institutions like Hyperliquid and S&P has weakened the value proposition of third-party oracles. After exhausting all alternatives, the core development contributor Switchboard Technology Labs Inc. has decided to cease operations, and all implemented versions are deprecated as of today.Protocols currently relying on Switchboard must immediately migrate to other oracle service providers, with the official recommendation being Pyth or Redstone as alternatives. The technical support team will provide migration guidance in the final week.

According to Cryptopolitan, over 100 researchers, using AI coding agents, have reduced the quantum attack resource score for the Bitcoin secp256k1 elliptic curve point addition subroutine by 86.1% (from 10.75 billion to 1.496 billion). This optimization only targets a single step in Shor's algorithm and does not break any private keys or transfer funds; a complete attack still requires fault-tolerant quantum hardware that does not yet exist. However, each efficiency improvement compresses the time window for quantum migration after blockchain completion.According to Glassnode data, approximately 6.04 million BTC (30.2% of the circulating supply) face potential quantum risks due to exposed public keys on-chain. Ethereum plans to achieve full quantum resistance by December 2029, while the Bitcoin community faces greater challenges at the governance level, including how to handle approximately 1.7 million suspected dormant P2PK address coins held by Satoshi, which remains unresolved.

Pine Analytics released the Zcash Q3 2026 report. Ironwood was activated on July 28 at block 3,428,143, and within five weeks, holders migrated 87% of their Orchard balance, with the new pool holding 3.84M ZEC as of August 31. The shielded supply increased by 9.9% to 4.86M ZEC, with the shielded ratio rebounding from 26.3% to 28.7%, recovering 440K from the 745K unshielded ZEC in June.The price of ZEC rose from $407 on June 30 to $836 on August 31, an increase of 106%. Grayscale ZCSH converted to a spot ETF, with assets growing from $155 million to $346 million. Mining difficulty rose by 35%, reaching an all-time high, with two corporate miners committing approximately $65 million in hash power. NU7 has no mainnet height yet, and holders will vote until September 14 to decide whether to launch before September 30 with a 25-second block time and smooth issuance; there are still 470K ZEC remaining in Orchard.

Coinbase announced that it has collaborated with Stanford University cryptography professor Dan Boneh and Localhost Research to hold a closed-door "Post-Quantum Bitcoin Workshop" at Stanford University, gathering Bitcoin developers, cryptography experts, researchers, institutional custodians, and hardware wallet specialists to discuss the technologies and migration plans for Bitcoin to address future quantum computing threats.The workshop focused on assessing the progress of quantum computing, post-quantum cryptography, and various post-quantum signature schemes applicable to Bitcoin, as well as discussing Ethereum's anti-quantum planning, the practical requirements faced by institutional custody businesses, and how to introduce post-quantum security mechanisms for Bitcoin through new output types. Participants believed that rather than predicting when quantum computing will pose a real threat to existing cryptographic systems, it is more important to establish well-tested response plans in advance.Quantum computing does not currently pose an urgent crisis, but the earlier research and coordination begin, the better we can avoid hasty network upgrades and asset migrations under pressure in the future. However, there is currently no consensus on a single post-quantum solution. Different solutions involve trade-offs in terms of security, transaction data size, hardware performance, key management, and the difficulty of user migration. Participants felt that Bitcoin's anti-quantum measures cannot rely solely on protocol layer upgrades, but must also consider how individual users, institutional custodians, wallets, and hardware devices generate, store, back up, and migrate keys and assets.

The G7 Cybersecurity Working Group stated in its latest report that quantum computing poses security threats to both public and private institutions, as well as economic threats, and relevant organizations should begin migrating to post-quantum cryptography (PQC) immediately. The working group noted that the migration process could take several years, and attackers can currently collect and store encrypted data to decrypt it once sufficiently powerful quantum computers become available.Quantum computing may also break digital signatures, leading to identity theft and exposing businesses and their supply chains. The report did not mention cryptocurrencies, but similar public key cryptography is used for blockchain wallets and transaction authorizations. Currently, quantum computers are unable to break Bitcoin's cryptography, but developers are considering post-quantum solutions such as BIP-360. Ethereum researchers plan to replace several cryptographic components used by accounts, validators, and applications. The Solana Foundation has tested post-quantum signatures on its testnet and launched an optional hash-based vault. The G7 working group also urged governments to support relevant research, public-private collaboration, and national PQC strategies.

Users need to switch to the corresponding USDC trading pair in advance to trade.

Ayo Akinyele, Senior Director of Engineering at Ripple, stated that the company is developing a four-phase quantum-resistant migration plan for the XRP Ledger, aiming to complete the transition before quantum computers become a real threat. The plan includes assessing the network's exposure, testing quantum-resistant cryptographic solutions, running existing security systems in parallel with quantum-resistant alternatives, and preparing emergency response pathways for scenarios where quantum computing advances exceed expectations.Akinyele emphasized that migration is not just about replacing a cryptographic algorithm, but requires more flexible infrastructure, stronger key management, and clearer upgrade paths. The XRP Ledger has supported changing the keys that control accounts without altering the accounts themselves, a feature that is expected to reduce the difficulty of future migrations, but independent validators on the network still need to coordinate any broader rule changes.Meanwhile, Anthropic's model last month reduced the workload required to break leading post-quantum signature candidates by 67 million times, and Bitcoin and Ethereum developers also released their respective migration plans this week. Akinyele pointed out that AI and quantum computing are different technologies, but they are driving financial infrastructure to evolve in the same direction, as AI agents begin to trade and pay autonomously, raising new requirements for payment infrastructure that is always online and natively internet-based.

Lisk announced that it is transforming into a modern funding operations platform aimed at financial teams. As part of this transition, Lisk Chain will gradually shut down, and the team has established an optional migration path to Celo for builders currently deployed on Lisk.In the relevant statement, Lisk introduced the key points of the migration arrangements to builders, emphasizing that this path is available for existing deployed projects to voluntarily choose in order to continue advancing their business during the shutdown process of the Lisk chain.
