## Staking description

Here is a description of each staking pool:

<table><thead><tr><th width="48">Pool ID</th><th width="281">Lock duration</th><th>Ratio</th></tr></thead><tbody><tr><td>1</td><td>12 months</td><td>8</td></tr><tr><td>2</td><td>6 months</td><td>4</td></tr><tr><td>3</td><td>3 months</td><td>2</td></tr><tr><td>4</td><td>1 months</td><td>1</td></tr></tbody></table>

APRs are indexed to the platform's activity. Here are the different sources of revenue that will be injected into the staking:

* 33% of deposits lost by users
* 5% of our customers' cash inflows
* 5% in-app purchases

Applicable staking APRs are revised on a monthly basis and can be viewed on our staking platfom <https://staking.ta-da.io/>.

## Properties

The main properties of our staking system are summarized below:

1. Two users who stake the same amount of tokens for the same lock period get the same amount of reward.
2. The reward depends on the number of tokens staked. A user who stakes twice as many tokens as another user in the same stake earns twice as much reward.
3. A token blocked in a stake with a ratio of 2 must earn twice as much reward as a token blocked in a stake with a ratio of 1.
4. No tokens are created or destroyed during redistribution.

**Example**

A user who stakes his tokens in the pool 4 (ratio of 1) will have to wait a month to be able to recover his locked tokens. During this period, he will earn rewards. Another user who stakes the same amount of tokens in the pool 1 (ratio of 8) will have to wait a year to get his tokens back. However, during this period, he will earn 8 times more tokens than the first user (if the latter were to stake his tokens every month in the pool 4 for one year).
