Multichain
Multichain describes apps, tokens or strategies spread across several blockchains at once, and the fragmented liquidity and users that result.
As fees on Ethereum rose and new networks appeared, most large crypto applications stopped living on a single chain. Lending markets, DEXs and stablecoins now deploy the same contracts on Ethereum, several layer 2s and other layer 1s, and wallets show balances across all of them. Multichain is the general label for that reality.
The approach lets projects reach users wherever fees are lowest and activity is highest, and stablecoin issuers mint natively on many chains to avoid relying on bridges. Investors and analysts increasingly compare protocols by their total footprint across networks rather than on one chain.
The cost is fragmentation. Liquidity is split between deployments, the same token can exist in several incompatible versions, and moving assets between chains depends on bridges, historically one of the most hacked parts of crypto. Users regularly send funds on the wrong network. The term should not be confused with Multichain, a cross-chain bridge that collapsed in 2023.
Example
A lending protocol runs separate markets on Ethereum, Arbitrum and Base, so a user with USDC on Base can borrow there without first bridging to Ethereum, but cannot use collateral posted on another chain.
