Mantle Joins $7.2 Billion Exodus From LayerZero to Chainlink CCIP

Mantle moves Super Portal to Chainlink's cross-chain standard

Mantle, a modular Ethereum layer-2 network, is moving its Super Portal cross-chain infrastructure from LayerZero to Chainlink's Cross-Chain Interoperability Protocol (CCIP). The switch replaces LayerZero's Omnichain Fungible Token (OFT) standard with Chainlink's Cross-Chain Token (CCT) standard. Mantle scheduled the migration for 9 to 15 July 2026. The change lets holders move the MNT token between Ethereum and Solana through a single interface.

Bybit built the Super Portal for Ethereum-Solana transfers

Mantle launched the Super Portal in January 2026 with Bybit, the second-largest cryptocurrency exchange by trading volume. The infrastructure links Ethereum's layer-2 environment with Solana's decentralized finance ecosystem. It lets users bridge MNT and reach liquidity pools on both networks through one interface. Byreal, a Solana-native exchange incubated by Bybit, hosts an MNT-USDC pool that supplies part of that liquidity.

Migration wave tops $7.2 billion since May

Mantle joins a broader shift across decentralized finance (DeFi). According to CoinDesk, more than $7.2 billion in cross-chain and wrapped assets have migrated from LayerZero to CCIP since May 2026. These figures reflect announced commitments from each project, not independently audited on-chain flows. Reported migrations include Kelp at $1.5 billion, Lombard at more than $1 billion, and Solv Protocol at $700 million in tokenized bitcoin. Virtuals Protocol reported $700 million, Re about $475 million, Kraken $330 million in wrapped assets, and Yuzu Money $54.5 million.

A bridge exploit triggered the industry shift

The migration wave followed a security breach earlier in 2026. Attackers drained roughly 116,500 rsETH, worth about $292 million, from a LayerZero-powered bridge operated by Kelp. The incident renewed concern about cross-chain bridge security, a segment that has lost billions of dollars to exploits in recent years. Bridges connect separate blockchains and hold pooled assets, which makes them frequent targets for attackers. Several projects cited that risk when they announced their move to CCIP.

MNT market cap holds near $1.4 billion

The MNT token traded at $0.43 at the time of publication, up 3.4% over the past 24 hours (CoinPaprika, 9 July 2026). Its market capitalization stood near $1.42 billion, and trading volume reached about $14.8 million over the prior 24 hours (CoinPaprika, 9 July 2026). The token remained down about 2.6% over the previous seven days. Mantle reported roughly $2.5 billion in value locked across its network.

Mantle frames the move around tokenized assets

Mantle framed the migration around the growth of tokenized financial assets. The network wants MNT to work as a cross-ecosystem asset across Ethereum, Solana, and centralized venues. Mantle expects the change to support its push into real-world asset tokenization and payment rails. Existing applications built on LayerZero will need updates during the transition, which could create temporary friction for some users.
