The Renzo Protocol project has entered the restaking market strongly, and it's a simple yet genius idea.
Instead of just staking a coin like $ETH , you can now do restaking, meaning you can use the same coin in multiple protocols to earn additional yields.
Renzo gives you ezETH tokens as a representation of your stake, and you can use them in other protocols to maximize benefits.
Risks? Yes, they exist, especially with smart contracts, but the yields are also tempting.
