Vanar introduces a smart market-aware fee mechanism designed to keep transaction costs stable, predictable and fair without relying on chaotic bidding systems. The diagram explains how Vanar dynamically updates transaction fees while protecting users from sudden price shocks.
Instead of changing fees on every block, Vanar checks the gas token price periodically (every 100 blocks). This delay-based mechanism ensures the network is responsive to real market movements, not short-term volatility. By comparing the transaction fee of the latest block with the fee from around 100 blocks earlier, the protocol determines whether an update is actually needed.
If prices remain stable Vanar simply reuses the transaction fee from the parent block, maintaining consistency for users and applications. This avoids unnecessary fee fluctuations and ensures developers can predict costs accurately. If a price mismatch is detected, the protocol fetches the latest token price via an external API. When a response is received quickly, Vanar recalculates transaction fees using the updated market price and applies it smoothly at the protocol level.
In cases where the API does not respond in time, Vanar prioritizes network continuity by falling back to the last known block price and retrying the update in the next block. This design prevents stalled blocks, fee spikes or network instability.
The result is a fixed-fee-like user experience backed by dynamic logic. Users enjoy predictable costs, while the protocol quietly adjusts in the background to reflect real market conditions. This approach eliminates gas wars, reduces uncertainty, and makes Vanar especially suitable for consumer apps, enterprises and large-scale platforms.
By combining automation, safeguards, and delayed updates, Vanar transforms transaction fees from a pain point into a stable infrastructure feature, bringing blockchain one step closer to mainstream usability.
