Staking SOL into BNSOL does not diminish your SOL balance. Both your SOL and earned rewards can be reclaimed based on the applicable conversion ratio at redemption.

The BNSOL:SOL ratio is not 1:1 because 1 BNSOL represents 1 staked SOL plus the staking rewards since 2024-08-26 06:04 (UTC). Due to the accumulation of staking rewards, the value of 1 BNSOL progressively exceeds that of 1 SOL. The ratio is updated daily to reflect the rewards earned from the staked SOL.

Example*: On 22 September 2024, the BNSOL:SOL conversion ratio was 1:1.01004105. When a user stakes 10 SOL, they would obtain 9.90058770 BNSOL based on the conversion ratio.

SOL staking rewards accumulate, and the user's BNSOL becomes worth more SOL. Three months later, on 23 December 2024, the BNSOL:SOL conversion ratio had grown to 1:1.01980774.

If the user redeems their BNSOL on that day, they would receive 10.09669596 SOL, which includes both their staked amount and the earned rewards.

*The numbers above are for illustrative purposes only. The actual scenario depends on the conversion rate at stake/redeem, the holding period of BNSOL, and on-chain SOL staking APR, etc.
