[DAO: QmVqgri] Keep Polygon transactions for free

by 0x87956abc4078a0cc3b89b419928b857b8af826ed (Nacho)

Should the following Tier 4: up to $60,000 USD, 6 months vesting (1 month cliff) grant in the Community category be approved?


Decentraland has been using Biconomy, a meta-transaction relayer, to provide free transactions in Polygon since the launch of the new user-generated collections in Polygon on June 1, 2021.

Biconomy, is changing his business model requiring projects to fund their own “Gas tank” to send meta transactions. Before they were costing all the transactions.

Since June 1, 2021 (~6 months ago) Decentraland has used 4k MATIC. I’m requesting ~15k MATIC to fund the Gas tank to keep transactions free in Polygon for at least ~1 year having into account that the average gas price can increase. They have increased from 1 to 30 some months ago

Grant size

45,000 USD

Beneficiary address



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

Biconomy announcement:

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.
  1. All the native tokens you deposit will solely be used to sponsor gas for your end-users.
  1. Gas management and analytics features will allow you to control gas spending, set limits, and be on top of gas accounting.


If the proposal passed, the steps will be:

  • Swap MANA to MATIC. We can use the Polygon MANA collected here by the Wearables submissions and primary sales.

  • Deposit MATIC into the gas tank. To do this we can follow the following tutorial.

The funding key for the Decentraland Meta Transactions is 1639137842389

The deposit smart contract needs to be passed by the Biconomy team yet.

Roadmap and milestones

Decentraland needs to action this as soon as possible to keep running meta transactions.

Notice that It should be a one-time payment without vesting
