Circle has announced a series of major updates to its Web3 services, aimed at improving support for developers building on its platform. These updates include the integration of the Solana (SOL) blockchain with Programmable Wallets, the introduction of a new Smart Contract API and the launch of the Circle Credits Program, according to circle.com.
Programmable wallets now support Solana
Circle’s programmable wallets now support the Solana blockchain, expanding the ability for developers to integrate secure multi-chain wallets into their applications. This integration abstracts away technical complexities such as managing private keys, node infrastructure, transaction fees, onboarding, and authentication flows. Initially, API support will focus on fungible token transfers and the ability to sponsor transaction fees on behalf of end users. Future updates are expected to add support for Non-Fungible Tokens (NFTs) and program interactions via Circle’s Smart Contract Platform.
Smart Contract Platform API update
Circle has announced the retirement of its existing read contract API endpoint, which will be replaced by a new contract query API endpoint on September 30, 2024. This new endpoint aims to improve the developer experience by allowing direct querying via blockchain and address, eliminating the need to import or deploy the smart contract before the query. Developers currently using the Read Contract endpoint are advised to migrate their applications to the new endpoint before the deadline.
Expand wallet services to more blockchains
Circle’s enterprise solution, Wallet Signing Service, is designed to bring secure Multi-Party Computation (MPC) wallets to new blockchains using well-known APIs and SDKs. This service integrates seamlessly with the blockchain infrastructure used for node and data management, simplifying the launch of secure on-chain applications. Key features include creating secure wallets, onboarding and authenticating users, securely signing transactions and messages, managing private keys with MPC technology, and accelerating development timelines with cross-chain APIs.
Circle Credits program
Circle has also introduced the Circle Credits Program, intended to give developers credits to subsidize their Web3 Services bills. These credits can be used to pay the monthly fees of Programmable Wallets, Smart Contract Platform API calls, and gas station network and platform fees. Developers are encouraged to sign up for the Circle Credits program to take advantage of these benefits.
These updates reflect Circle’s continued commitment to supporting the developer community and improving the functionality of its Web3 services. For additional details, developers can refer to Circle Developer’s terms of service.
