Chainlink’s Cross-Chain Interoperability Protocol is now bridging Coinbase’s cbBTC from Base to Monad, the high-performance EVM-compatible Layer-1 built for high-frequency finance. This enables Bitcoin-backed liquidity to flow into Monad’s DeFi ecosystem for the first time. Applications including Curvance and Neverland are already building cbBTC lending and borrowing markets on Monad at launch.
The integration uses Chainlink’s Cross-Chain Token standard, the same infrastructure Coinbase adopted as the exclusive bridging layer for its entire wrapped asset expansion program.
JUST IN: Chainlink connects cbBTC to Monad DeFi.

Rather than operating a custom bridge with its own validator set and associated security assumptions, cbBTC moves through CCIP’s battle-tested relay network, infrastructure that has processed over $27 trillion in on-chain transaction value.
The architecture matters – bespoke bridges have historically been the primary attack surface for wrapped asset exploits, and routing through a standardized interoperability layer with institutional-grade security reduces that risk materially.
Monad is built for high-performance finance. It offers 10,000 transactions per second, sub-second finality, and negligible fees. This architecture is ideal for BTC-denominated derivatives, structured products, and high-frequency lending. Historically, Ethereum’s throughput constraints made these applications impractical for Bitcoin-backed collateral.
The timing of the Monad expansion seems perfect, coming when the wrapped Bitcoin competitive landscape is reshaping rapidly. Carrying a market cap of approximately $5.6 billion with around 85,000 tokens in circulation at the time of writing, cbBTC has grown from a 0% to around 30% wrapped Bitcoin market share since its launch in September, 2024.
WBTC, once near monopolistic, has seen its dominance fall significantly as cbBTC, Binance’s BTCB, and newer entrants capture share, with total wrapped BTC market cap peaking at $35 billion in September, 2025.
A shifting trust dynamic is the primary driver of this market migration. WBTC faced significant custody controversy following BitGo’s partnership with BiT Global, a Hong Kong-based entity linked to Justin Sun. This move prompted major DeFi protocols like Aave and Compound to restrict or reduce their exposure to WBTC as collateral. It’s reasonable to argue this loss of confidence has directly accelerated the adoption of cbBTC.
Coinbase’s institutional backing, exchange-grade custody infrastructure, and 1:1 BTC proof-of-reserve model give cbBTC a credibility advantage that is compounding into market share.
The strategic logic for both parties is clear. Monad gains a premier, liquid BTC-denominated asset as a foundational collateral primitive for its nascent DeFi ecosystem, which matters enormously for bootstrapping TVL without relying entirely on native token incentives.
Chainlink CCIP adoption by Coinbase, Galaxy, and others confirms cross-chain interoperability is moving from architectural preference to market standard. Institutions selecting settlement infrastructure are converging on a single protocol layer.

Coinbase and Chainlink extend cbBTC’s addressable liquidity surface to a high-throughput chain, purpose-built for the finance use cases where Bitcoin-backed yield and leverage make most sense.
Chainlink CBO, Johann Eid, framed it specifically.
“With Coinbase already using CCIP as exclusive bridging infrastructure, $5+ billion in cbBTC can move into Monad while maintaining the institutional-grade security required to manage billions in cross-chain flows.”
The question going forward is whether developer uptake on Monad, still in early ecosystem formation, translates cbBTC availability into genuine trading volume and TVL, or whether the integration remains underutilized until Monad’s user base matures.
