ETHGlobal

excited to share what we built this weekend with @frankk, @orbulo and @darph 

a frame to execute transactions by prompting in plain english thanks to brian, your web3 ai assistant!

we support two operations on @base and @optimism:
- swap
- bridge

"swap 0.01 eth for usdc on base"

https://brian-frame.builders.garden

Yesterday we shipped the @Brian frame to perform swap and bridge transactions via prompt directly on @farcaster without leaving the social. Still a non-custodial solution where the user signs in with their Farcaster wallet.

How the Brian API works:

We have implemented the /transaction endpoint where you can pass a text prompt as a string and an address of the wallet that wants to perform the transaction and it returns the transaction object (from, to, value, date) and some additional parameters.

The additional parameters are: token in and token out info (address, symbol, decimals, USD price, etc..) protocol used, gas cost, transfer amount equivalent in USD, and so on.

For example, a prompt like "swap 10 usdc to dai on Base" gives the following:

Brian API is a general-purpose API, access to the data in your frame/app is simple. In this example we we leave the choice of route to the users (/transaction endpoint returns if possible more than one). transactionCalldata is just the /transaction endpoint response:

Brian API with Farcaster Frame challenges:

Frames can have a max of 5s to complete an action. Brian's API takes a little longer, so we created an async request-handling system that runs the process in the background and later returns the result of the call using Qstash and Redis
