Symbiotic and Eigenlayer are two emerging protocols in the restaking field, but their design philosophies are vastly different. Symbiotic emphasizes permissionless and modular features, supports multi-asset and customizable parameters, and uses immutable core contracts, reducing governance risks. Eigenlayer, on the other hand, focuses on ETH and its derivatives, adopts a more centralized management approach, simplifying operations but presenting bundled risks. The launch of Symbiotic and its collaboration with the Mellow protocol offer more options and airdrop opportunities for the DeFi community. The competition and cooperation between the two will further drive the development of the restaking market.
