# Ethereum Delegated Transactions Widget
[](https://github.com/zitros/ethereum-delegated-tx-widget/actions)
Elegant Ethereum delegated transactions implementation.
Primarily, delegated transactions, or meta transactions allow users to pay fee in tokens instead of Ether, making crypto user experience great again. This widget is shipped with the [back end](https://github.com/ZitRos/ethereum-delegated-tx-service), which can be used for any token or smart contract supporting doing-something-via-signature.
+ Highly customizable widget and a stand-alone page
+ Can work **with any token** which supports function delegation (but you have to set up a back end for it)
+ Helpful hints, which allow to quickly onboard inexperienced users
+ Signature standard-free paradigm (use any signature your contract supports, e.g. `eth_personalSign`, `eth_signTypedData`)
+ Automatically picks an icon of your token (from Trust Wallet repository)
→ CHECK THE DEMO HERE! ←
Need test tokens? Use this widget via this link
