World Liberty Financial’s USD1 stablecoin is now operable across multiple blockchains through an integration with Chainlink’s Cross-Chain Interoperability Protocol (CCIP), the companies announced Friday. That’s according to World Liberty Financial’s team, Chainlink co-founder Sergey Nazarov, and the son of U.S. President Donald Trump, Eric Trump, who announced the cross-chain capabilities at Consensus 2025. USD1, a U.S. dollar-backed stablecoin launched by the decentralized finance protocol inspired by Trump, has seen significant growth since its debut, reaching $2 billion in market capitalization. The stablecoin was used to close MGX’s $2 billion investment in Binance. It still trails behind industry leaders Tether and Circle, whose leading stablecoins have a $151 billion and $60.6 billion market cap, respectively. The token is backed by short-term U.S. Treasuries and fiat reserves held by BitGo Trust. The stablecoin was for now largely siloed within single blockchain ecosystems, yet the CCIP integration will allow it to move freely across blockchains. Ethereum and BNB Chain are the first blockchains being integrated, though additional blockchain support is expected in the future. The integration, the firms say, tackles a long-standing hurdle in the stablecoin market: cross-chain security. Historically, vulnerabilities in cross-chain bridges have cost users nearly $3 billion, they added. “Chainlink's battle-tested infrastructure delivers the institutional-grade security and extensive reach needed to deliver USD1 into the hands of millions across a growing number of active, on-chain ecosystems,” said Zach Witkoff, co-founder of World Liberty Financial. The collaboration builds on an earlier integration where Chainlink’s price oracles were used to support World Liberty’s deployment of an Aave v3 instance.
