What Is Bridge (Cross-Chain Bridge)?
Definition
A blockchain bridge is a protocol that transfers tokens or data between two different blockchains — enabling assets created on one chain to be used on another.
Bridges solve the interoperability problem: tokens on Solana can't natively interact with Ethereum, and vice versa. Bridges lock tokens on the source chain and mint equivalent "wrapped" tokens on the destination chain.
How bridges work: 1. You deposit tokens on Chain A (e.g., SOL on Solana) 2. The bridge locks those tokens in a smart contract 3. The bridge mints equivalent "wrapped" tokens on Chain B (e.g., wSOL on Ethereum) 4. To bridge back, you burn the wrapped tokens and unlock the originals
- Wormhole — connects Solana, Ethereum, Base, and 20+ chains
- Portal — Wormhole's token bridge interface
- Base Bridge — official Coinbase bridge between Ethereum and Base
- Allbridge — multi-chain bridge supporting Solana and EVM chains
For token creators, bridges expand your token's reach. A token created on Solana can be bridged to Ethereum for access to a larger DeFi ecosystem. However, each bridged version is a separate token with separate liquidity — you need pools on both chains.
Note: CoinDevTools creates native tokens on each chain. If you want your token on multiple chains, create separate native tokens rather than bridging — this avoids bridge risks and gives you native liquidity on each chain.
