Cross-chain bridge Allbridge has announced the integration of its Allbridge Core with Circle's cross-chain transfer protocol (CCTP). This update enables Allbridge Core users to benefit from minimum slippage cross-chain transfers on all USDC routes that support CCTP. The new swapping options will provide support for USDC transfers between Avalanche, Arbitrum, and Ethereum.

Matthew Sigel, head of digital asset research at VanEck Associates, said he is unsure if Circle will conduct an IPO until USDC's market share stabilizes. Earlier, Golden Finance reported that Circle Internet, a stablecoin issuer, is considering an IPO in 2024. Insiders revealed that the company is in discussions with advisors and preparing for a potential initial public offering, but the deliberations are still ongoing.

On November 14th, Circle's cross-chain transfer protocol (CCTP) will go live on the Cosmos ecosystem application chain Noble on November 28th, allowing users to migrate USDC between blockchains in a single transaction, and any user on a blockchain that supports CCTP can transfer assets to Noble.<br>Circle's cross-chain transfer protocol (CCTP) on Noble allows users to easily, simply, and securely send their USDC directly from other chains to the dYdX Chain.

Circle's co-founder and CEO Jeremy Allaire announced that Circle Research has released a white paper on "Robust Thresholds ECDSA Signatures" and an open-source Golang implementation of CGG+21 threshold signatures. The goal is to identify signature signers who behave improperly in real-time by combining the CGG+21 signature protocol with the CGG+21 traitor tracking protocol, allowing third-party observers to identify malicious signers in real-time to improve blockchain transaction security. Circle Research also stated that the CGG+21 signature algorithm is a recommended update to GG18. Users of Binance tss-lib GG18 library can switch to Circle Research's CGG+21 signature module while retaining their existing keys. CGG+21 requires fewer communication rounds than GG18 and can significantly shorten signature time in cold storage scenarios.

Circle, the stablecoin issuer, has launched an upgrade for its USDC and EURC stablecoins, which includes decreased gas costs, improved support for account abstraction, and increased security for transactions on EVM blockchains. The upgrade is fully backwards-compatible and does not require any action from developers or users. The blockchain security firm Halborn audited all the code changes, and Circle plans to roll out the upgrades starting on November 9th and completing them over the next few months. The upgrades will also include improvements to checking blocklists, better resilience against forks, and a one-time rename for the EURC symbol from EUROC.

Stablecoin issuer Circle Internet is reportedly considering an IPO in 2024.

Jeremy Allaire, co-founder and CEO of stablecoin issuer Circle, announced on social media that Circle's new products will soon launch on the Solana blockchain, including its Euro stablecoin EURC and cross-chain transfer protocol CCTP. Once CCTP completes its support for Solana, users will be able to send and receive USDC stablecoins between Ethereum, Cosmos, AVAX, and other Layer 2 networks that support EVM.

Stablecoin issuer Circle will be closing individual accounts on November 30, according to emails received by customers. The company confirmed that business and institutional "Mint" accounts will remain available. The reason for the closure is part of Circle's strategic review and may be due to a drain on reserves caused by a network of individual accounts operating as KYC mules or money-laundering intermediaries. Some speculate that the closure may also be part of a cost-cutting or restructuring exercise.
