INTEROPERABILITY AND CROSS-CHAIN FINANCE

Bridge

A protocol that enables the transfer of assets or data between different blockchain networks by locking tokens on one chain and minting equivalent representations on another. Bridge security failures represent one of the highest exploit risk vectors in crypto.

EXAMPLE

Circle's Cross-Chain Transfer Protocol allows USDC to move between Ethereum, Solana, and other chains while maintaining reserve backing and reducing reliance on third-party bridge operators.

Related Terms

Interoperability

The ability of different blockchain networks, protocols, and traditional financial systems to exchange data and value seamlessly. Institutional adoption depends on cross-chain interoperability solutions that connect permissioned and public blockchains.

Example

Chainlink's Cross-Chain Interoperability Protocol enables banks to move tokenized deposits between different blockchain networks while maintaining a single source of truth for regulatory reporting.

Cross-Chain

Referring to transactions, operations, or protocols that span multiple blockchain networks. Cross-chain settlement is essential for institutions managing tokenized assets across different chains while maintaining unified balance sheet reporting.

Example

J.P. Morgan's Kinexys platform performs cross-chain atomic swaps, enabling clients to exchange tokenized deposits on one blockchain for tokenized securities on another without centralized intermediaries.

Wrapped Asset

A tokenized representation of a cryptocurrency from one blockchain that is made available on a different blockchain, backed 1:1 by the original asset held in custody. Wrapped Bitcoin (WBTC) on Ethereum is the most widely used wrapped asset.

Example

DeFi protocols on Ethereum require institutions to convert bitcoin holdings to Wrapped Bitcoin to use BTC as collateral in on-chain lending platforms, introducing custody and counterparty risk.
