ChainATM

What it does

ChainATM is an A.I. model that fulfills buy orders on chain with the help of Google Gemini 1.5 Pro, Chainlink Functions and the PayPal SDK. A smart contract is deployed on Ethereum, ready to be triggered after the fiat payment is done with PayPal. Chainlink basically brings the internet into a smart contract which normally work in kind of silos by allowing API Requests to any source outside. For the first time ever, you can buy USDC with a simple text message. It takes about 90 seconds to confirm two transactions on chain until the money is released from the contract to the given recipient address.

The main use-case of the Gemini API was to create a buddy-like persona with restrictions on how to behave. We figured out that structured prompts work much better instead of freeform prompts. The model uses a given context (crypto transaction expert specializing in fiat to crypto conversions), behavior (soft-skills: friendly, talking like a long-known friend) and has two main tasks to accomplish. 1 - Extract user input and 2 - check the given recipient address for correctness. Correctness means that the given address starts with '0x' followed by 40 characters. The model will also be a consultant to help the normie user from web2 to onboard as smooth as possible by making recommendations regarding wallets.
