The process of generating equivalent lightning tokens is called mapping.
What is a smart contract?

If the cryptocurrency is to be transferred out of MAS Pay wallet, please click on the currency you want to propose. Here, take Bitcoin as an example. Click “Propose” to fill in the general currency collection address and amount. To export coins to the general wallet, both MASX and BTC gas fee are deducted. At the same time, BTC gas fee will be deducted from the proposed amount. After confirming, the currency will be transferred to the general wallet.
Do I need to pay gas fee for using lightning?
When using MAS Pay wallet’s lightning payment function, you need to deposit the currency into MAS Pay wallet. Take Bitcoin as an example. The process of depositing only consumes BTC as gas fee. If there is already a transfer/receipt amount in MAS Pay wallet, only MASX will be consumed during the transfer process.

For example, Bob wants to exchange 1BTC for 3ETH with Alice, both of them only need to deposit the required amount into MAS Pay wallet, exchange through the chain mapping technology, Bob and Alice can instantly receive BTC and ETH, without trading trouble steps such as other pipelines are exchanged for the required currency, so it is different from the function of general wallet as asset storage.
Why the transaction fails even my wallet has enough assets to pay for gas fees?
Because Bitcoin’s trading model is calculated in UTXO, the full name is Unspent Transaction Outputs, which is a no-cost transaction. The blockchain is used to illustrated and can be regarded as a decentralized public account. Each node can perform verification and data backup for each transaction, but no node has a book record of all account balances, so every time a transaction occurs, the miner must confirm the entire blockchain. Whether the amount transferred has not been spent or the correct amount of money to be transferred in the chain assets. In short, it is best to follow the one-in-one-out principle in the operation transfer/receipt process. If you use the one-input and multi-out operation, MAS Pay wallet will jump out tips of the transaction failure (the assets and gas fee are sufficient), then you have to transfer Bitcoin (or USDT of the bit protocol) in order to transfer assets again.
Do you have to use MAS Pay to use the lightning payment function?

What is the GAS fee?
For example, when you want to transfer money between different bank accounts, you must pay the commission for the services provided by the bank. Similarly, the miners in the blockchain should package your transactions and put them on the blockchain. While the transaction is completed, and the computational resources of the blockchain are consumed in the process, so the gas fee is paid. The miners prioritize the high-cost miners’ transactions. If the miners paid by the users are very low, the trade may not be packaged by the miners, causing the trade to fail.
