Zcash Network Fees

Key Facts

• The transaction fee is public even when sender, recipient, amount, and memo fields are shielded.
• ZIP 317's conventional fee scales with logical actions and gives ordinary transactions a two-action grace window.
• The conventional minimum for a transaction inside that grace window is 10,000 zatoshis, or 0.0001 ZEC.
• An observed 24-hour median is telemetry, not a protocol rule or a live quote for the next transaction.
• Median is usually more representative than average when rare large values or parser mistakes can skew the distribution.

Two different questions hide behind Zcash fees

When someone asks what a Zcash transaction costs, they may mean the policy a wallet should use or the fees transactions actually paid over a period. Those are related but different. The Network Truth Console answers the observed-data question; the detailed fee guide explains wallet construction and ZIP 317.

Keeping the two separate prevents a common mistake: treating yesterday's median as a guaranteed quote for a transaction whose inputs, outputs, notes, or cross-pool structure may be different.

What the observed median means

The 24-hour median is the middle reported fee after transactions in the provider's window are ordered by fee. Half fall at or below it and half at or above it, subject to the provider's transaction set and parsing.

A median of 10,000 zatoshis is consistent with many ordinary wallets using the ZIP 317 conventional minimum. It does not say every transaction paid that amount. Consolidations, batches, complex shielded actions, custom settings, or broken software can produce other values.

Why House of Zcash does not headline the average

A mean adds all reported fees and divides by the transaction count. One extreme outlier can pull it far away from what a normal wallet paid. Explorer parsing errors around shielded and cross-pool value can also create absurd values that look mathematically valid in an API response.

During source review, Blockchair's reported average was many orders of magnitude above its median and ordinary ZIP 317 expectations. The site rejects that average as misleading rather than laundering it into a polished card. The median remains labeled as a third-party observation.

How ZIP 317 sets the conventional fee

ZIP 317 uses a marginal fee of 5,000 zatoshis multiplied by the greater of two grace actions or the transaction's logical-action count. The two-action floor supports an ordinary recipient-plus-change shape and privacy padding without charging a simple shielded transfer as if privacy were a premium add-on.

The policy is not a consensus tax that makes every alternative fee invalid. It guides wallet construction, relay, mempool treatment, and block-template behavior. Maintained wallet software should normally calculate it rather than asking a user to guess.

Why shielded does not mean the fee is hidden

The conventional fee must be computable from public transaction data. That lets nodes evaluate relay and mining policy without learning private note selection details. As a result, the fee remains an observable feature even when protected payment fields are encrypted.

A distinctive manual fee can become a correlation signal. Choosing unusual values for style or habit is therefore poor privacy hygiene. The safer default is consistent, current wallet policy.

How to use the metric

Use the observed median to understand recent network behavior, compare broad periods, or spot a distribution that deserves deeper inspection. Use your wallet's approval screen to decide what a real transaction will pay. The wallet knows the transaction it is constructing; an aggregate chart does not.

Always read the provider, time window, unit, and sample definition. Zatoshis are the smallest ZEC unit, with 100,000,000 zatoshis in one ZEC. A page that drops the unit or silently converts between policy and observation is not doing enough work.
