VoidAI Platform Fee Structure

This document explains all fees charged across VoidAI platform operations.

1. Overview

VoidAI charges fees for the following operations:

TAO Bridging — Bittensor ↔ Ethereum
Alpha Token Bridging — Bittensor ↔ Ethereum
Token Swapping — xTAO ↔ subnet Alpha tokens (Ethereum)
CCIP Asset Transfer — wTAO / wAlpha between Ethereum and CCIP-enabled chains (Base, Solana)

For each operation, one or more of the following may apply:

Network Fee — Fixed fee covering source-chain gas
Platform Fee — Percentage or fixed minimum (whichever is higher)
Ethereum Gas Fee — Dynamic, based on network congestion
CCIP Bridge Fee — Dynamic, charged by Chainlink (for CCIP transfers)

Ethereum gas is always estimated in real time and displayed before transaction confirmation.

2. Fee Summary

Operation	Platform Fee Rule	Fixed Network Fee	Gas Requirement
TAO: Bittensor → Ethereum	Higher of 0.5% or 0.005 TAO	0.002 TAO	Ethereum gas (dynamic)
TAO: Ethereum → Bittensor	None	0.002 TAO	Ethereum gas (dynamic)
ALPHA: Bittensor → Ethereum	Higher of 1.5% or 0.015 ALPHA	0.006 ALPHA	Ethereum gas (dynamic)
ALPHA: Ethereum → Bittensor	None	0.006 ALPHA	Ethereum gas (dynamic)
Token Swap (Ethereum)	Higher of 0.25% or 0.0025 xTAO	None	Ethereum gas (dynamic)
CCIP Transfer (EVM ↔ Base/Solana)	Higher of 0.5% or 0.005 (bridged token)	None	Source chain gas + CCIP fee

How the Variable Fee Works

For bridging and swap operations:

The platform fee is calculated as the higher of the percentage fee or the fixed minimum.

This ensures Ethereum gas costs are covered even for small transfers.

8. CCIP Asset Transfer (Ethereum ↔ Base / Solana)

The CCIP bridge enables transfers of:

wTAO
wAlpha

between Ethereum and CCIP-enabled chains.

CCIP Fees

Fee Type	Details
Platform Fee	Higher of 0.5% or 0.005 (in bridged token)
CCIP Bridge Fee	Dynamic (charged by Chainlink)
Ethereum Gas	Paid from wallet (dynamic)

Important: About CCIP Fees

CCIP fees are set and collected by Chainlink.
VoidAI does not control or receive any portion of this fee.

Supported Routes

Source Chain	Destination Chain	Supported Tokens
Ethereum	Base	wTAO, wAlpha
Base	Ethereum	wTAO, wAlpha
Ethereum	Solana	wTAO, wAlpha
Solana	Ethereum	wTAO, wAlpha
Base	Solana	wTAO, wAlpha
Solana	Base	wTAO, wAlpha

Example — Bridging 50 wTAO (Ethereum → Base)

Item	Amount
Transfer amount	50 wTAO
0.5% fee	0.25 wTAO
Fixed minimum	0.005 wTAO
Applied platform fee	0.25 wTAO
Amount received (before CCIP fee)	~49.75 wTAO

CCIP fee and Ethereum gas are displayed before confirmation.

9. Frequently Asked Questions

When are fees deducted?

Fees are deducted at transaction confirmation.
All amounts are shown before you approve.

Why does Ethereum gas vary?

Ethereum gas fluctuates based on network congestion.
Current estimated gas (in Gwei) is displayed before confirmation.

What if my transfer is too small?

If your transfer is smaller than the minimum fee required, the transaction will not process.

Are Alpha fees the same for all subnets?

Yes. The Alpha fee structure applies uniformly across all subnet Alpha tokens.

Can fees change?

Fixed fees and percentages may be updated by VoidAI.
Ethereum gas always fluctuates dynamically.
