Mantle has announced a major upgrade to its cross-chain infrastructure by migrating its legacy bridge system to Chainlink Cross-Chain Interoperability Protocol (CCIP). The move will make Chainlink CCIP the exclusive infrastructure powering the Mantle Super Portal, a cross-chain gateway developed with Bybit.
The transition represents a significant step for Mantle as the network prepares its ecosystem for larger-scale asset movement across multiple blockchains. With more than $2.5 billion worth of MNT tokens involved in the migration, the upgrade highlights the increasing demand for institutional-grade security standards in blockchain interoperability.
As decentralized finance, tokenized assets, and global blockchain payments continue expanding, secure cross-chain communication has become one of the industry’s most important infrastructure challenges.
Mantle Replaces Legacy Bridge With Chainlink CCIP
The Mantle Super Portal previously relied on legacy bridging infrastructure, but the network is now moving to Chainlink CCIP as its primary cross-chain solution. The upgrade is designed to provide stronger security guarantees while allowing MNT assets to move between networks more efficiently.
According to Mantle, the migration will improve the way MNT teleportation operates between major blockchain ecosystems, including Ethereum and Solana. The goal is to create a foundation that allows MNT to interact with more chains, platforms, and financial applications as adoption grows.

Cross-chain bridges have historically been among the most targeted components in the cryptocurrency industry due to the large amounts of capital they manage. Several major bridge exploits in previous years have demonstrated the risks associated with moving assets between independent blockchain networks.
By adopting Chainlink CCIP, Mantle is aligning its infrastructure with a security-focused interoperability standard designed for institutional applications. Chainlink has positioned CCIP as a framework for secure communication between blockchain networks, enabling assets and messages to move across ecosystems with additional security layers.
The migration also reflects a broader trend among blockchain projects moving away from independently developed bridges toward standardized interoperability solutions.
Institutional Security Becomes Critical as Blockchain Value Grows
The partnership between Mantle and Chainlink comes as blockchain networks increasingly compete to attract institutional capital and real-world financial applications. As more assets move on-chain, infrastructure providers are under greater pressure to deliver reliability, transparency, and security.
Mantle said the Super Portal upgrade was driven by the need to match higher security requirements as more value flows through the platform. The network emphasized that Chainlink CCIP provides the infrastructure needed to support future growth and broader adoption.
The migration process temporarily paused Mantle Super Portal transfers beginning July 9 at 1 PM UTC, with services expected to resume after the upgrade is completed. Mantle stated that user funds remain secure during the transition and that transfers will automatically resume once the migration concludes.
For Chainlink, the integration adds another major blockchain ecosystem to its expanding CCIP network. The protocol has already become a key component for projects seeking secure cross-chain communication, particularly those targeting institutional and enterprise use cases.
The move also strengthens Chainlink’s position as a leading provider of blockchain infrastructure beyond price feeds. While Chainlink initially gained adoption through decentralized oracle services, CCIP represents a broader ambition to become the interoperability layer connecting different blockchain networks.
As tokenized assets, stablecoins, and blockchain-based financial products continue gaining adoption, the ability to securely transfer value across multiple chains will become increasingly important. Mantle’s decision to adopt Chainlink CCIP demonstrates how major blockchain ecosystems are prioritizing security and scalability as they prepare for larger volumes of cross-chain activity.
The Super Portal upgrade could ultimately serve as a foundation for Mantle’s expansion into a more interconnected blockchain economy, where digital assets can move seamlessly between networks while maintaining stronger security standards.
