Liquidity Vault

1. Vault Basics

1.1 What is Omni Vault?

Omni Vault is a liquidity pool where users provide liquidity for the cross-chain bridge. Vaults are distributed across various External Chains (such as Ethereum, BSC, Polygon, etc.). Users deposit assets into the Vault to support cross-chain transactions and earn Vault Fee as rewards.

1.2 Key Features

Feature	Description
Unified Asset Model	Same assets on different chains are fully equivalent, Vaults share earnings equally
Multi-chain Distribution	Each asset has Vaults on multiple chains, forming a liquidity network
Revenue Sharing	Vault providers share cross-chain transaction fees (Vault Fee)
Simple & Transparent	Fixed fee rate, predictable earnings

1.3 User Participation Flow

1. User selects chain and asset (e.g., USDC on Ethereum)
2. Deposit assets into the corresponding chain's Vault contract
3. Receive Vault Token (LP certificate)
4. Start earning Vault Fee share

2. Vault Fee Earnings

2.1 Fee Rate

Item	Current Rate	Note
Vault Fee	0.018%	Adjustable via governance

2.2 Earnings Calculation

User Earnings = Cross-chain Amount × Vault Fee × (User Vault Token / Total Vault Token)

2.3 Earnings Examples

Assuming user holds 10% share of a chain's USDC Vault (at current 0.018% rate):

Daily Volume	Total Vault Fee	User Earnings (10% share)
$1,000,000	$180	$18
$10,000,000	$1,800	$180
$100,000,000	$18,000	$1,800

2.4 Annualized Yield Estimation

Assuming Vault TVL is $1,000,000, user deposits $100,000 (10% share), at current 0.018% rate:

Daily Volume	Annual Vault Fee	User Annual Earnings	APY
$1,000,000	$65,700	$6,570	6.57%
$5,000,000	$328,500	$32,850	32.85%
$10,000,000	$657,000	$65,700	65.7%

Note: Actual earnings depend on trading volume, Vault TVL, and the Vault Fee rate at that time
