Each week, we answer a frequently asked question around Biconomy’s ecosystem.

Cool new projects are integrating Gasless to onboard users.

So what’s the best way to leverage Gasless?

𝙁𝙤𝙡𝙡𝙤𝙬 𝙖𝙡𝙤𝙣𝙜🧵👇

/2

There are 3 ways to make your #dApp’s contract meta-transaction compatible with #Gasless:

✅ via Standard EIP 2771
✅ via Custom Implementation
✅ via smart Contract Wallet

/3

Choosing an approach depends on application drivers, including time optimization, smart contract compatibility, & dev resources:

☑️Choose 1) EIP2771 approach if you are looking for:

- a standardized implementation
- the ability to register specific methods to make gasless

/4

And, minimal changes on the client side

- you're ready to set up a trusted forward in your smart contracts.

This allows you to use @biconomy Forward without any changes in your contracts to enable paying in #ERC20 tokens.

/5

☑️Choose 2) the custom implementation approach if you're looking for:

- a case-oriented approach. For example, permit or gasless tokens are inherited from EIP712 MetaTransactions.sol specs need more code changes.

- control over the message structure that the user signs

/6

☑️Choose 3) the Smart Contract Wallet Approach if you're looking for:

- options for changes or updates to support native #metatransaction
