Circle Launches Bridge Kit for Cross-Chain Stablecoin Development
On October 22, Circle CEO Jeremy Allaire announced the launch of a new developer toolkit called Bridge Kit. This toolkit is designed to simplify the building of cross-chain stablecoin applications and streamline access to the Cross-Chain Transfer Protocol (CCTP).
Bridge Kit functions as an abstraction layer and integration toolkit for developers. It encapsulates the complex underlying mechanisms of CCTP, such as signature proof handling and multi-chain communication, into simple APIs. This allows developers to build cross-chain stablecoin applications without requiring deep technical expertise. The initiative significantly lowers the barrier to innovation, enabling teams to concentrate on application logic and user experience, while further promoting USDC adoption and liquidity unification across multiple chains.
BlackRock’s BUIDL Fund Deploys Another $500 Million to Aptos
On October 22, BlackRock’s Digital Liquidity Fund (BUIDL) allocated an additional $500 million worth of tokenized assets on the Aptos network. This deployment makes Aptos the second-largest blockchain by BUIDL fund allocation, trailing only Ethereum. As of the reporting time, the total value of tokenized real-world assets (RWAs) on Aptos has surpassed $1.2 billion, positioning it third globally in this category.
The BUIDL fund, a collaboration between BlackRock and the tokenization infrastructure provider Securitize, is supported by cash, U.S. Treasuries, and repo agreements, which are characterized as low-risk, high-liquidity assets. Initially launched on Ethereum in March 2024, the fund expanded its reach to Aptos and other blockchain networks in November 2024. This strategic move highlights the increasing integration of blockchain infrastructure by traditional finance entities. Aptos is emerging as a significant platform for institutional on-chain asset deployment, attributed to its high performance, robust security, and low transaction fees.
Decentralized Oracle Network APRO Secures Strategic Funding Round
On October 22, the decentralized oracle network APRO announced the successful completion of a new strategic funding round. The round was led by EASY Residency under YZi Labs, with contributions from Gate Labs, WAGMI Venture, and TPC Ventures. The specific amount raised in this funding round was not publicly disclosed.
From an industry infrastructure standpoint, oracles serve a critical role as the middleware that connects blockchains with real-world data. The reliability of these oracles directly influences the quality and security of external data accessible to on-chain applications. Consequently, APRO’s expansion and development are considered a key component of the evolving decentralized data ecosystem.
