Automated market maker​

An automated market maker is a smart contract on Fiero that holds on-chain liquidity reserves. Users can trade against these reserves at prices set by an automated market making formula.

FRO20​

FRO20 tokens are fungible tokens on Fiero. Fieres swap supports all standard ERC20 implementations.

Factory​

A smart contract that deploys a unique smart contract for any FRO20/FRO20 trading pair.\

Pair​

A smart contract deployed from the Fieres swap Factory that enables trading between two FRO20 tokens.

Pool​

Liquidity provider / LP​

A liquidity provider is someone who deposits an equivalent value of two FRO20 tokens into the liquidity pool within a pair. Liquidity providers take on price risk and are compensated with fees.

Mid price​

The price between what users can buy and sell tokens at a given moment. In Fieres swap this is the ratio of the two FRO20 token reserves.

Price impact​

Core​

External smart contracts that are useful, but not required for Fieres swap to exist. New periphery contracts can always be deployed without migrating liquidity.

Flash swap​

A trade that uses the tokens being purchased before paying for them.
