 ### Re-staking money to the liquidity pool
 Currently it is only possible to join the liquidity pool by providing a specific amount of the two tokens of the token-pair. However, a provider could want to provide more money in the future in order to receive more rewards. For this, we would recommend another screen for this functionality, which will show the pools that the user has joined. After choosing a pool, the user should be able to send more amount of tokens to the pool. Whenever the pool receives this request, it should confirm that the provider has already joined the pool and update the provider's staked amount for the rewards to be consistent with this amount. However, this will introduce some problems in finding the amount staked by a specific provider, since it will not be just the two transactions received by the `BLOCK_TYPE_JOIN` block.
