Description

In the Ethereum world, things happen thanks to transactions. These transactions, just like everything in life, don’t come for free. In order to create and execute a transaction, you need to pay a fee in the form of “Gas” which costs ETH. But what if you want to create a transaction and you don't want to pay for gas. This is where Meta-Transactions come. **Meta-transactions** are transactions whose data is created and signed off-chain by one person and executed by another person who pays the gas fees. **Decentraland** has been using meta transactions to provide users the best possible experience through the dApps and the explorer. For example, creators have been creating **~600 smart contracts (collections)** without knowing that they were doing that and creating and trading **~630k NFTs** without spending any MATIC/ETH. Data from [here](https://thegraph.com/hosted-service/subgraph/decentraland/collections-matic-mainnet?query=Totals) [Biconomy announcement:]( https://bit.ly/3EF7dO4) > We are super excited to announce the much-awaited product upgrade - Personalised Gas Tanks. In the future, each dApp will have its gas tank to sponsor gasless transactions for the end-user. What are the benefits of the gas tank? > 1. You get your very own and private gas tank for your dApp, which ensures that no transaction gets dropped or fails due to insufficient funds. > 2. All the native tokens you deposit will solely be used to sponsor gas for your end-users. > 3. Gas management and analytics features will allow you to control gas spending, set limits, and be on top of gas accounting.
