Mantle Moves MNT to Chainlink CCIP After $7.2 Billion Exodus

Key Takeaways

  • Mantle is moving its Super Portal from LayerZero to Chainlink CCIP, pushing announced migrations to CCIP above $7.24 billion.
  • The Super Portal is used for MNT transfers between Ethereum and Solana and is switching from LayerZero’s OFT standard to Chainlink’s CCT standard.
  • During the migration from July 9 to 15, the Super Portal will be temporarily paused, while existing MNT on Ethereum and Solana will stay untouched.

Mantle is shifting its Super Portal from LayerZero to Chainlink’s Cross-Chain Interoperability Protocol, or CCIP. With that move, the total value of announced migrations to CCIP now tops $7.24 billion (€6.3 billion). It also highlights just how competitive cross-chain infrastructure has become, as projects put more weight on security and tighter control over how tokens move between networks.

Mantle Chooses the CCT Standard

According to Mantle, the Super Portal it built with Bybit is moving from LayerZero’s Omnichain Fungible Token standard to Chainlink’s Cross-Chain Token standard. The portal handles MNT transfers between Ethereum and Solana, and Mantle says support for more blockchain networks will follow later.

The change applies to Mantle’s native token, which the project says has a network value above $2.5 billion (€2.2 billion). Mantle says the switch should also make it simpler to manage token pools and transfer settings directly through the CCT standard, while opening the door for MNT to expand across more blockchain networks and tokenized asset markets.

Security Still Comes First

The move also reflects a broader shift in crypto, where bridges and cross-chain messaging systems are facing much closer scrutiny. That layer of infrastructure is essential, but it is also one of the biggest security weak points in the industry, since a single flaw can put hundreds of millions of dollars in user assets at risk.

That concern was reinforced earlier this year by the $292 million (€256 million) KelpDAO exploit, which made the risks tied to LayerZero configurations even harder to ignore. In response, LayerZero Labs introduced tighter security measures, including mandatory multi-verifier setups and additional infrastructure hardening.

What This Means for Crypto in Europe

For European crypto readers, the takeaway is that infrastructure decisions can change quickly once security and control start to outweigh existing integrations. That matters especially for projects operating across multiple chains and for teams that want to issue or move tokenized assets between different networks.

Mantle says the Super Portal will be paused temporarily during the migration, which is set to run from July 9 to 15. The project says existing MNT on Ethereum and Solana, as well as MNT activity on Byreal and Bybit, will remain untouched.
