# Staking

### Staking $ARCHIVE Tokens

Chainback's staking system allows $ARCHIVE token holders to earn passive income in ETH. This system not only supports the Chainback ecosystem but also provides token holders with an opportunity to be a part of the platform's growth and development.

The ETH reward size is determined by the proportion of an individual's staked $ARCHIVE tokens relative to the total staked in a specific pool, and the amount of ETH in the reward pool.

The APR rate for staking is calculated using the formula: <mark style="color:orange;">Staked Amount / Total Staked Amount \* 100.</mark>&#x20;

Staking $ARCHIVE tokens is a strategic move for token holders, offering them a chance to earn passive income while contributing to the stability and security of the $ARCHIVE token. By locking tokens in staking, they are temporarily removed from market circulation, reducing volatility and supporting the token's value.
