Solana Joins Bitcoin and Ethereum in ICP Integration for Cross-Chain Smart Contracts

• ICP’s integration of Solana alongside Bitcoin and Ethereum unlocks powerful cross-chain functionality, expanding Solana’s DeFi potential.
• While short-term volatility persists, Solana’s long-term price trajectory looks strong—especially if ICP-powered interoperability drives new use cases.

Dfinity’s Internet Computer Protocol (ICP) has already sewn together code with Bitcoin and Ethereum—now it’s bringing Solana aboard. As described in a Crypto News Flash (CNF) article, Internet Computer (ICP) is a decentralized, open-source blockchain designed to provide scalable, high-performance smart contract execution and dApp development.

As of June 18, developers can build “canisters” (ICP’s smart contracts) that speak natively with Solana via Chain Fusion technology—no middleman bridges required. As shared in a recent tweet by the official DFinity X account, the announcement revealed that Swapping SOL for BTC fully on-chain is no longer a dream.

Swapping SOL for BTC fully onchain is no longer a dream.

The completion of the ICP Roadmap's Helium milestone brings Solana and ICP closer together with the SOL RPC canister. Other canisters now have the services they'd have if a Solana RPC node were directly on the…

Why this is important is that because this latest milestone marks a major leap forward in cross-chain functionality. By integrating Solana into its Chain Fusion system, ICP now supports fully decentralized interactions across three of the most important blockchains: Bitcoin, Ethereum, and Solana.

In this article, however, we will focus on the Solana market price implications, this is because with the introduction of the SOL RPC canister, developers gain the ability to build apps that can directly connect to Solana’s infrastructure—just as if a Solana RPC node were running natively on ICP.

Bigger Opportunities for DeFi — and What’s Going on With Solana’s Price?

Deviating from CNF’s previous prediction that SOL was establishing lower lows while gradually climbing, recent analysis shows renewed optimism for Solana’s price trajectory following the ICP integration. This upgrade enhances interoperability and is likely to attract DeFi liquidity from a potential 4.8 million daily active Solana users.

Price forecasts for 2025 suggest that SOL could reach $400, driven by bullish sentiment and technical indicators like a potential golden cross. However, risks such as network congestion or regulatory scrutiny could limit gains, with a possible low near $250 if bearish trends take over.

Nevertheless, the integration’s ability to combine Solana’s high throughput with ICP’s efficient processing could further solidify Solana’s position—supporting a climb toward $500 if market conditions align.

Despite being one of the top 6 cryptocurrencies by market value, Solana (SOL) is now priced at $145.30, with a daily decline of 0.50% and an 8.54% drop over the past week, according to CoinMarketCap. Its strong price base and large user community make it a perfect match for ICP’s cross-chain plans. See the SOL price chart below:
