I was trying to implement gasless transactions. Is it possible to achieve it using fuel?
Hey @shivamlync, we have an example for the gasless NFT mint over here, you can have a look at the Gas Predicate Sway Contract that holds gas Eth. The way it works is that predicates have certain predefined conditions, and once these conditions are met (for example: checking if the address is whitelisted), then the predicate will release Eth for the gas for this transaction.

Fuel doesn’t have good tooling yet for gasless transactions. But Fuel is uniquely capable of delivering a seamless gasless transaction at the native level (b.c. of our multi-input multi-output, multi-party transactional design).
If we want to do them properly, we will want to do them in all predicates the same way at the native level.
This will take a bit of time to map out and standardize. But it’s on the roadmap.

Wouldn’t this cause an issue ?
i assume the transaction construction is going to happen on the frontend
If that is the case then any whitelisted address can just add
transactionRequest.tip = very large value
and drain out all the ETH in the predicate
Yes the user won’t make any profits but still
