# DeFi Ecosystem

Certain MET Synths can be obtained on the open market, using [Curve Finance](https://curve.fi/#/ethereum/swap?from=0xdac17f958d2ee523a2206206994597c13d831ec7\&to=0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee) or other DEXes, such as [Aerodrome](https://aerodrome.finance/) on Base or [Velodrome](https://velodrome.finance) on Optimism. 

These synths can immediately be swapped on the MET Synth Marketplace for other synths.

In time, these Curve LP tokens for example may have additional yield-bearing opportunities, such as a pool on Vesper Finance, or as a collateral asset on other DeFi platforms.
