Bridge
A protocol that enables the transfer of tokens, data, or smart contract commands between different blockchain networks, enabling interoperability in the multi-chain ecosystem.
Cross-Chain Bridge
A protocol enabling transfer of assets and data between different blockchains, allowing users to move cryptocurrency across chains while maintaining value equivalence.
ERC-20
The technical standard for fungible tokens on Ethereum. Defines a common interface that enables any ERC-20 token to work smoothly with wallets, exchanges, and dApps.
ERC-721
The technical standard for non-fungible tokens (NFTs) on Ethereum. Each ERC-721 token is unique with individual ownership and metadata, enabling digital collectibles and unique assets.
Layer 2
Scaling solutions built on top of a base blockchain (Layer 1) that process transactions off-chain while inheriting the security of the underlying network.
Oracle
A service that provides external, real-world data to smart contracts on the blockchain, acting as a bridge between on-chain code and off-chain information sources.
Sidechain
A separate blockchain running parallel to a main chain, with its own validators and consensus, connected via bridge enabling asset transfers between chains.
