PancakeSwap Adds Cross-Chain Swaps With ERC-7683, Following Uniswap’s Lead

focus-text-wrap]Key Takeaways[/focus-text-wrap]

• PancakeSwap has launched a new cross-chain swaps feature for BNB, Arbitrum, and Base.
• Using ERC-7683, the feature enables users to execute complex cross-chain transactions.
• Developed by Uniswap Labs and Across, the ERC-7683 standard has helped popularize intent-based frameworks.

In 2024, Uniswap Labs and Across published ERC-7683, a new intent-based standard for cross-chain interactions. Given the two decentralized exchanges’ (DeXs) similar design, it was only a matter of time before PancakeSwap entered the fray. 

Using a new ERC-7683 integration launched on Wednesday, June 11, PancakeSwap users can now swap tokens between BNB Chain, Arbitrum, and Base in a single transaction.

What is ERC-7683?

The proliferation of Layer 2 networks (L2s) and sidechains has helped scale Ethereum significantly in recent years. However, it has also created additional friction, with crypto assets now distributed across multiple chains rather than concentrated on the Ethereum mainnet. 

ERC-7683 was designed to resolve friction by creating a universal standard for cross-chain interactions between Ethereum-compatible chains.

The standard is based on “intents,” which abstract away the complexity of bridging between blockchains.

Behind the scenes, new decentralized exchange actors known as “fillers” compete to fulfill each desired intent. However, from the perspective of decentralized exchange users, cross-chain trades can be executed in a single transaction.

Cross-Chain Intent Adoption

While several blockchains already embraced intent-based frameworks, ERC-7683 created a unified language, allowing them to interoperate for the first time.

Among DeX protocols, Uniswap led the way, integrating ERC-7683 into UniswapX.

As intent-based DeXs and bridges gain traction, ERC-7683 has already received support from more than 35 L2s and sidechains, including Arbitrum, Optimism, and Base.

Now, PancakeSwap’s latest standard implementation takes the technology a step further.

From Bridging to Cross-Chain Swaps

In comments to CCN, Across co-founder Hart Lambur observed that “PancakeSwap’s integration goes beyond same asset bridging—it combines bridging and swapping into a single action.” 

“Architecturally, the relayer network executes a multistep intent: source token, destination chain, destination token.” But the user doesn’t see any of that. “They just interact with the same PancakeSwap interface they already use,” he added.

A year after ERC-7683 was first published, the new feature is “one of the first real examples of how intents can enable complex cross-chain actions without changing the front-end at all,” Lambur said.
