-## Overview
-
-To use the Movement Network, users need to pay for _transaction fees_ in \$L2MOVE tokens. As the \$MOVE token is minted on Ethereum (\$L1MOVE), users need to transfer some \$L1MOVE tokens from the Ethereum network to the Movement Network (to get $L2MOVE), and back.
-This asset transfer capability is provided by the Movement Network **native bridge**, which is a [lock/mint bridge](https://chain.link/education-hub/cross-chain-bridge#types-of-cross-chain-bridges) described in [MIP-58](tdc).  
-
-This bridge (transfer) operation requires several steps, two of which are transactions:
-
-1. initiate a transfer on one chain;
-2. finalize the transfer on the other chain.
-
-Step (1) is performed by the user on the network (Ethereum or Movement), and step (2) is performed by the bridge operator via a _relayer_ (**ADD link to relayer MIP here**).
-As a result, the operator has to cover the transaction fees for the _finalize_ step.
-When transferring from Ethereum to Movement, the fees are expected to be very low so we can consider that the operator can cover them using a pool of transaction fees collected from the users on the Movement Network.
-In the other direction, bridging from Movement to Ethereum, the Ethereum fees are expected to be higher, and the operator may not be able to cover them all.
