Transfer USD in ETH to a friend

The contract is currently deployed on 0x7B4b667F9B792054565e10656d1A08ECF50aa31C on the goerli network.

Build

You need to have Foundry and node installed to run this example.

To build

cd ./contract
forge install foundry-rs/forge-std@2c7cbfc6fbede6d7c9e6b17afe997e3fdfe22fef --no-git --no-commit
forge install pyth-network/pyth-sdk-solidity@v1.0.1 --no-git --no-commit
cd ../app/
npm ci

Testing the contract

Simply run forge test on contract directory. It runs the tests located in contract/test directory.

Deploy and run

forge create src/PythExample.sol:PythExample \
  --rpc-url <GOERLI_RPC> --mnemonic <MNEMONIC_PATH> \
  --constructor-args
  "0xff1a0f4744e8582DF1aE09D5611b887B6a12925C" \
  "0xca80ba6dc32e08d06f1aa886011eed1d77c77be9eb761cc10d72b7d0a2fd57a6"

0xff1a0f4744e8582DF1aE09D5611b887B6a12925C is the Pyth contract address on Goerli network and 0xca80ba6dc32e08d06f1aa886011eed1d77c77be9eb761cc10d72b7d0a2fd57a6 is the ETH/USD price feed id.

Replace PYTH_EXAMPLE_ADDRESS in app/src/App.tsx to the new deployed address. Finally, run npm run start on app directory to start the UI and interact with your contract.
