[Glossary] Cross-Chain & Wrapped Assets Terms

CryptoKas

Below is a concise glossary of key terms you’ll encounter in Cross-Chain & Wrapped Assets discussions. Definitions are clear and practical—ideal for anyone navigating multichain liquidity and token transfers.

Cross-Chain Mechanisms

Cross-Chain Bridge: A system that moves assets or data between two blockchains by locking on one chain and minting a representation on another.
Lock & Mint: The process where original tokens are locked in a contract on Chain A and an equivalent wrapped token is minted on Chain B.
Burn & Redeem: The reverse flow—wrapped tokens are burned on Chain B, triggering release of the locked originals on Chain A.
Pegged Asset: A token on Chain B whose value is “pegged” 1:1 to an underlying asset on Chain A (e.g., wBTC ≈ BTC).
Liquidity-Pool Bridge: Bridges that draw from shared liquidity pools rather than locking reserved tokens, enabling dynamic swaps.

🪙 Wrapped Assets

Wrapped Token: A smart-contract token representing an asset from another chain (e.g., wETH, wBTC) so it can be used in a new ecosystem.
Custodial Bridge: A bridge run by a centralized custodian who holds the locked funds—simpler but introduces counterparty risk.
Trustless Bridge: Fully decentralized bridges using smart contracts and on-chain proofs, minimizing need to trust any single party.
Federated Bridge: Operated by a known group of nodes or validators, requiring m-of-n signatures to move assets—balances decentralization and performance.

Interoperability Protocols

Atomic Swap: Peer-to-peer exchange of tokens across chains without a bridge, executed via hashed time-lock contracts to ensure either both sides complete or neither does.
Relayer / Validator Node: Off-chain actors that monitor one chain and relay proofs or messages to another, enabling cross-chain communication.
IBC (Inter-Blockchain Communication): Cosmos’ protocol for secure, standardized messaging and token transfers between independent blockchains.
Smart-Contract Router: Contracts that route cross-chain transfers through the optimal bridge or protocol based on fees and liquidity.

️ Security & Risks

Bridge Fee: Charge levied by a bridge for processing cross-chain transfers—covers gas, proofs, and operator costs.
Front-Running / Sandwich Attacks: When attackers exploit pending bridge transactions to manipulate token prices on the destination chain.
Reentrancy & Exploit Risk: Security vulnerabilities in bridge contracts that can be attacked to drain locked assets.
Oracle Risk: Bridges relying on price or state oracles can be compromised if the oracle is manipulated or fails.

Tools & Integrations

Multichain / Anyswap: Popular protocols offering a suite of bridges for dozens of chains with UI and API support.
Wormhole: A messaging bridge connecting Solana, Ethereum, Terra, and others via guardian networks.
Hop Protocol: Layer-2 bridge for fast transfers of ERC-20 tokens between rollups and Ethereum.
LayerZero: Omnichain messaging protocol that connects smart contracts across chains with on-chain verification.
