Web3 Services: June 2024 Updates

Web3 Services Developer

Blog_w3s-juneIn June, we released important updates to support developers building on Programmable Wallets including support for the Solana blockchain, and the Circle Credits Program to help subsidize fees once apps are launched on mainnet. Learn more below.


Programmable Wallets: now available on Solana

Programmable Wallets now supports the Solana blockchain! Programmable Wallets’ APIs and SDKs help developers embed secure, multi-chain wallets in apps, abstracting away technical complexities like managing private keys, node infrastructure, transaction fees, onboarding, and authentication flows. 

We’re kicking off with API support for fungible token transfers and the ability to sponsor transaction fees on behalf of end users. Stay tuned for future releases where we’ll expand to include support for NFTs, and program interactions through Smart Contract Platform.

Check out our interactive tutorials to start building now.


Smart Contract Platform contract read API deprecation

The read contract API endpoint (contracts/{id}/read) will be deprecated and replaced by the new contract query API endpoint (contracts/query) on September 30.

This new endpoint provides a better developer experience by:

  • Querying directly by blockchain and address instead of the Circle contract ID.
  • Removing the need for importing or deploying the smart contract before the query
If you are using the contract read endpoint, please migrate your application and use the new endpoint no later than September 30.
