Liquidity Source

A liquidity source is a contract or account where tokens can be exchanged.

Due to the extensibility of the 0x Protocol, not all liquidity sources are tagged.

There are three special cases for liquidity sources:

• Multiple: When more than one liquidity source is used in a Transaction, to see the actual liquidity sources, check the Fills of this transaction.

• PLP: Stands for a Private Liquidity Provider, that is using the Pluggable Liquidity Sandbox.

• 0x RFQ: Off-chain Professional Market Maker

Liquidity Source
