The Dfinity Foundation has unveiled a cutting-edge API called EVM RPC, designed to boost cross-chain interoperability for Internet Computer (ICP) smart contracts. This innovative solution enables ICP smart contracts to seamlessly read and write on any Ethereum Virtual Machine-compatible chain, such as Optimism, Arbitrum, and Base, without relying on intermediaries. The API also supports the Bitcoin blockchain and is set to expand to Solana in the near future.

The EVM RPC API simplifies multi-chain dApp development and eliminates the need for bridges and wrapped tokens, allowing native chain interactions and liquidity facilitation through network API keys. This means that developers can now write a single ICP smart contract that can custody Bitcoin, for example, and programmatically trigger sending it based on events observed on an Ethereum DeFi smart contract.

In addition to the API, Dfinity has also introduced an interoperable stablecoin called ckUSDC, pegged 1:1 to Circle's USDC stablecoin, on the ICP network. USDC is the second-largest stablecoin with a market capitalization of $32.83 billion, according to CryptoSlate's data. The ckUSDC token, a multi-chain "twin" of USDC, leverages chain-key cryptography and ICP smart contracts that directly hold original assets. It operates similarly to ICP's other inter-ecosystem tokens, like ckBTC and ckETH.

Since its launch, ckUSDC has gained significant traction with notable projects such as IC Lighthouse, ICPSwap, and Helix Markets, reflecting the growing demand for this type of token. Lomesh Dutta, DFINITY's Growth President, highlighted the significance of this innovation, stating that the launch of ckUSDC and the new read/write APIs will foster further development within ICP's ecosystem. He emphasized that "with the addition of ckUSDC and read/write APIs, dozens of different chains can now leverage ICP smart contracts to freely interact with other networks, making the Web3 ecosystem massively more interoperable and unified."

This breakthrough technology has far-reaching implications for the crypto industry, enabling true multi-chain interoperability and allowing developers to create complex, cross-chain applications with ease. As the ecosystem continues to evolve, it will be exciting to see the innovative use cases that emerge from this technology. With Dfinity's API and ckUSDC, the possibilities for cross-chain interactions and liquidity facilitation are endless, paving the way for a more unified and interconnected Web3 ecosystem.
