Earn Yield by Powering the Zero-Gas Network
TrueCash uses a Decentralized Relayer Network. By running a lightweight Relayer Node on your computer, you pay the tiny blockchain network fees for buyers, and the protocol instantly rewards you with a guaranteed profit margin in TCASH.
1. Deposit BNB
Fund your local Relayer Wallet with a small amount of BNB. This is used to pay the network gas fees when a customer buys a product.
2. Relay Transactions
Your node listens to the public mempool. When a buyer signs a purchase, your node races to submit the transaction to the blockchain.
3. Earn Profit
The TrueCash Smart Contract intercepts the trade, calculates exactly how much BNB you spent, and automatically refunds you the equivalent value in TCASH + 10% Profit!
The Incentives Explained (The Math)
Because TrueCash is built on top of the Binance Smart Chain, transactions are incredibly cheap. A typical Zero-Gas transaction costs about $0.05 in BNB.
// Example Transaction
Gas Cost Paid by Your Node: $0.05 (BNB)
Base Refund from Smart Contract: $0.05 (TCASH)
Protocol Profit Premium (10%): $0.005 (TCASH)
Total Reward Deposited to You: $0.055 (TCASH)
If your node processes 10,000 transactions a month, you are effectively converting your BNB into TCASH at a permanent 10% discount compared to the market rate, generating a massive APY on your idle BNB!
