Canonical BSC Settlement Hub

While QanVault allows ticket purchases from multiple networks, all draw logic, ticket ledgers, prize escrow vaults, and winner claim operations execute canonically on BNB Smart Chain (BSC).

Architectural Rationale: Why BSC?#

The decision to settle all operations on BNB Smart Chain was driven by three technical and economic factors:

1. Gas Efficiency for Micro-Transactions and Prize Claims

On Ethereum mainnet, executing a complex contract interaction (such as minting 50 tickets or claiming a prize) can cost between $10.00 and $45.00 during elevated gas conditions.

On BNB Smart Chain, the equivalent transaction costs approximately $0.02 to $0.08 in BNB, allowing:

  • Players to buy small ticket batches (e.g. 10 tickets for $12.40) without paying 50% in gas overhead.
  • Winners to claim prizes of any size without losing a substantial portion of their reward to validator tips.
  • Keeper bots to execute automated draw triggers and commit-reveal randomness reliably at 00:00:00 UTC without incurring excessive infrastructure costs.

2. High-Volume QANX Liquidity

BNB Smart Chain hosts the primary decentralized exchange liquidity pool for wrapped QANX on PancakeSwap v3:

  • Contract Address: 0xAAA7915B350aE002B4109403423A39C57cf30663
  • Pair: QANX / WBNB and QANX / USDT
  • This deep pool guarantees tight spreads and minimal slippage when converting token payments into the prize asset.

3. Rapid Finality (3-Second Blocks)

BNB Smart Chain produces blocks every 3 seconds, enabling near-instant ticket confirmations, zero lag between payment and portfolio updates, and rapid commit-reveal draw resolution.

What This Means for Players#

  1. If you pay with BNB or BSC USDT:

Your purchase and settlement happen on the same chain. You experience zero bridging delay and pay minimal transaction fees.

  1. If you pay with Ethereum ETH or ERC-20 USDT:

You execute your purchase on Ethereum. Your ticket IDs are minted into the canonical BSC ledger, and your payment is routed across the bridge.

  1. When you win:

You switch your wallet network to BNB Smart Chain and claim your prize in wrapped QANX.

  1. Cashing out:

Once you claim your QANX on BSC, you can:

  • Hold QANX in your wallet.
  • Swap QANX for USDT or BNB directly on PancakeSwap v3.
  • Bridge QANX back to Ethereum via Symbiosis Finance or the official bridge if you prefer holding native ERC-20 tokens.
