Upbit Accidentally Accepts Counterfeit APT Tokens, Initiates Retrieval EffortsUpbit, South Korea’s largest cryptocurrency exchange, is reported to have accepted deposits of counterfeit Aptos (APT) tokens, mistaking them for their legitimate counterparts. The exchange has been reaching out to the sellers of these tokens by phone, requesting their recovery. This news has been circulating in several online crypto communities since the afternoon of September 24 (Korea Standard Time).Photo by Kenny Eliason on UnsplashUpbit’s responsesOn September 24 at 15:47 KST, Upbit announced a temporary suspension of deposit and withdrawal services for APT due to maintenance on the APT wallet. Following this, at 22:32 KST on the same day, Upbit explained that system maintenance was undertaken after identifying an unusual attempt linked to APT deposits. The crypto exchange went on to announce that the deposit and withdrawal services for APT would resume at 23:00 KST on the same day.DeFi degenerates’ insightsIn relation to this incident, Definalist, a group of DeFi degenerates based in Korea, shared insights on X (formerly Twitter). The group stated: “It seems that during the process of reflecting $APT coin deposits, there was a failure to check the type arguments, and all same functions transfers were recognized as the same APT native token. … If all APT ecosystem tokens were sent to Upbit’s wallet, they would have been mistakenly treated as APT native coins.”Decimal place differenceDefinalist also remarked on the fortunate nature of the counterfeit APT token having six decimal places, in contrast to the authentic APT token’s eight. They noted that if the deceptive token had mirrored the genuine token’s decimal places, the market disruption could have amplified a hundredfold. Meanwhile, the value of the counterfeit APT tokens deposited into Upbit is estimated to be about KRW 20 million (approximately $15,000).

OKX collaborates with Polygon Labs on layer-2 network launchSeychelles-incorporated OKX, one of the world’s largest cryptocurrency exchanges, has collaborated with blockchain development firm Polygon Labs to unveil the testnet for its latest zero-knowledge layer-2 network, named “X1.”Photo by Shubham Dhage on UnsplashIntroducing “X1”The company announced initial details on X1 via a press release published on Tuesday. This Ethereum-based ZK network has been constructed using the Polygon Chain Development Kit (CDK), with OKX playing a pivotal role as a core contributor to the CDK. Substantial engineering resources are being invested by OKX to strengthen the Ethereum scaling solution.The new network will serve to bolster the utility of OKX's native token, OKB. OKB will be used for X1’s gas fees. There has been a lot of chatter about the utility of exchange tokens following the collapse of FTX, as that platform was over-reliant on its native token in propping up the exchange. Similarly, critics are speculating that a comparable dynamic may be at play at Binance, relative to its native token BNB.Likely buoyed by news of this development, OKB observed a 10% unit price increase on Tuesday. However, that move has retraced downwards in the meantime.ZK proof technologyX1 has been designed with ZK proofs, a method through which one party can convince another that a particular claim is true without disclosing details of the claim itself. In this way, X1 ensures high security and scalability while mitigating transaction costs. The network seamlessly aligns with Ethereum, facilitating the secure deployment of EVM-based dApps and connectivity with a wide array of smart contracts, wallets and tools. OKX underscores X1’s status as its new native network.Chief Innovation Officer of OKX, Jason Lau, expressed optimism about X1, deeming it integral to the firm’s efforts in guiding users into the realm of Web3. Lau emphasized the scalability and accessibility of X1, especially for developers who can leverage it to construct user-friendly Web3 applications while maintaining interoperability with other networks.The collaboration with Polygon Labs marks another milestone in the evolution of Polygon’s CDK. Launched in August, the CDK enables the development of layer-2 blockchains on Ethereum, emphasizing zero-knowledge proofs. Networks deployed using the CDK gain the ability to connect to a shared ZK bridge, fostering interoperability.Sandeep Nailwal, co-founder of Polygon, underscored the significance of X1’s adoption of Polygon CDK technology, envisioning a future where CDK-deployed chains interoperate and coexist within a larger network of ZK-powered layer 2s in the Polygon CDK ecosystem. The CDK has gained traction, with various Layer 2s, including Immutable zkEVM, IDEX, Palm Network and Astar zkEVM, currently in development using this technology.Industry trendA trend is developing among crypto exchange platforms and their involvement in establishing layer two networks. Earlier this year, U.S. crypto platform Coinbase introduced the Base network, an Ethereum layer-2 network that focuses on offering a safe, low-cost and developer-friendly mechanism to build on-chain.Last week, it emerged that another leading U.S.-based crypto platform, Kraken, is on the lookout for a development partner to enable it in building out its own layer-2 blockchain network. According to those reports, it’s understood that Kraken is considering partnering with Polygon Labs, Matter Labs or the Nil Foundation.As this OKX-Polygon Labs collaboration progresses, the industry will continue to observe how X1, with its innovative technology stack and seamless integration with Ethereum, contributes towards broader Web3 development.

Komainu Partners with Copper to Enable Off-Exchange SettlementsKomainu, a well-established and regulated custody service provider and subsidiary of Japanese financial services conglomerate Nomura, has recently unveiled a new partnership with Copper, a digital asset solutions firm.This collaboration offers institutional clients of Komainu a means through which they can access off-exchange settlements. At a broader level, it is another significant development in progressing digital assets infrastructure.Photo by Gerd Altmann on PixabayClearLoop network accessKomainu, which was originally launched by Nomura in conjunction with Ledger and CoinShares, will be accessing Copper’s ClearLoop network as part of this collaboration. This partnership brings a host of possibilities for institutional clients of Komainu.What makes this collaboration particularly noteworthy is its ability to merge Komainu’s regulated, on-chain custody with the advanced off-exchange settlement capabilities of ClearLoop. As the institutional adoption of digital assets continues to gain momentum, the focus on managing custody and counterparty risk has never been more critical. Recent events, such as the collapse of the crypto exchange FTX alongside a plethora of crypto lending platforms, have served as stark reminders of the significance of robust custody solutions in this space.ClearLoop network growthClearLoop, with its distinctive feature of holding assets until just before a trade execution, effectively mitigates counterparty risk by seamlessly connecting multiple exchanges within a single trading network. This innovative approach eliminates the need to transfer assets to an exchange-based wallet, streamlining and fortifying the institutional trading process.UK-based Copper has been making market in-roads with its off-exchange settlement tool which it first launched in 2020. In March crypto exchange platform Huobi signed a memorandum of understanding (MOU) with Copper with the intention of joining the ClearLoop Network. Bitstamp, the world’s oldest crypto exchange, followed in April with its intention to integrate with ClearLoop.Singapore’s Matrixport was next to join in May, followed by Seychelles-headquartered crypto exchange Bitget in August.The leaders of both companies, Nicolas Bertrand, CEO of Komainu, and Dmitry Tokarev, CEO of Copper, expressed their enthusiasm for this partnership. Bertrand highlighted the importance of diversifying counterparty risk and commended the partnership’s ability to offer clients the best of both worlds. He emphasized that by combining Copper’s proven processes and connectivity with Komainu’s on-chain, segregated, and regulated custody platform, this partnership is set to raise the industry’s standards significantly.UK regulatory approvalEarlier this month, Komainu achieved a further milestone when it received regulatory approval from the UK’s Financial Conduct Authority (FCA) to operate as a custodian wallet provider. This achievement aligns with the regulatory framework established to combat money laundering, terrorist financing, and fund transfers.In a landscape where institutions are increasingly embracing digital assets, the partnership between Komainu and Copper demonstrates that the industry is moving towards ushering in a new era of more secure, efficient, and trustworthy financial markets. With the FCA’s regulatory approval, Komainu is solidifying its attempts towards adhering to the industry’s most rigorous security and compliance standards.
