How does POL Storage Staking work?

POL accounts stake 1 POL for every 100 KB of state storage. This is not a fee; the staked balance is 100% refunded when the storage is freed.

Q: How is a POL transaction fee calculated?

POL gas is measured deterministically in Gwei (10^12 gas units). Fees are charged based on compute effort and converted to POL at the current gas price (minimum 0.00005 POL base fee).

📦 POL Storage Staking Reservation (1 POL / 100 KB)

100% Refundable

POL accounts reserve state storage by staking tokens rather than paying monthly rent. Every 100 KB allocated requires 1 POL locked in state. When data or keys are deleted, the locked POL is unlocked and restored to your spendable balance!

Frequently Asked Questions — Polygon PoS Gas & Storage Staking

How is a POL transaction fee calculated?

Every POL transaction converts gas burnt into POL: Total Fee = Gwei Burnt × Gas Price. The base gas price is 100M Wei per gas unit, resulting in a minimal base fee of ~0.00005 POL.

Why does POL use Storage Staking instead of rent?

State rent models in older chains cause accounts to expire if fees run out. POL instead ties state storage directly to token balance: holding data locks 1 POL per 100 KB. This permanently preserves state solvency while keeping data 100% refundable.

What is 1 Gwei in POL units?

1 Gwei equals 10¹² gas units. It roughly equals 1 millisecond of compute time on a validator node. A standard block can process up to 300 Gwei across chunk receipts.

How are staking delegator rewards distributed?

POL distributes ~5% annual protocol inflation, yielding ~8.5% APY for staking delegators. Rewards compound automatically every epoch (~12 hours).
