Inspiration
We have the problem. If you don't have native token of blockchain, you can't send transaction. It's sad story.
What it does
Metapipe use "Meta transactions", for pay gas of transactions in ERC-20 tokens instead native token of blockchain
How we built it
Alice want send ERC-20 tokens to Bob, but Alice doesn't have native token of blockchain.
Alice signing transaction, send transaction's sign to our relayer, and relayer send this transaction instead Alice with sign data of Alice. Realyer pay gas in native token of blockchain. Transaction send on our smart contract. Smart contract verify sign of transaction, take fee in ERC-20 tokens and send ERC-20 tokens to Bob
Challenges we ran into
Everything ok
Accomplishments that we're proud of
It's very useful dapp
What we learned
We know everything
What's next for Metapipe
We want add to Metapipe feature: "Pay gas in fiat currency". For example, you can mint NFT without cryptocurrency
