-## Foundry
+## Tea Scripts
 
-**Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.**
+This repo contains scripts to run on a local devnet of the Layer Tea network to verify the network's functionality.
 
-Foundry consists of:
+### Prerequisites
 
--   **Forge**: Ethereum testing framework (like Truffle, Hardhat and DappTools).
--   **Cast**: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
--   **Anvil**: Local Ethereum node, akin to Ganache, Hardhat Network.
--   **Chisel**: Fast, utilitarian, and verbose solidity REPL.
+- Run a local devnet, and save the L2 RPC URL.
+- Set `PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80` in your environment (this corresponds to a prefunded address on the devnet)
+- Set `OWNER_PRIVATE_KEY=???` in your environment (this is the address who can update the fallback price and oracle)
+- Run the `Deploy.s.sol` and `Airdrop.s.sol` scripts on the `GPGWallet` repo (you must use the same `PREFUNDED_PRIVATE_KEY` for these transactions so signatures are consistent).
 
-## Documentation
+### GPG Wallet Script
 
-https://book.getfoundry.sh/
+- Copy the address of the wallet with the `0x49CEB217B43F2378` Key ID to `AddSigner.s.sol` (which corresponds to the GPG key used to provide the signature in that script)
+- Run `forge script --rpc-url [L2RPC] script/GPGWallet/AddSigner.s.sol:AddSignerScript --broadcast`
+- Verify that the transaction succeeded and the terminal output confirms the signer was added
 
-## Usage
+### L1 Data Fee Script
 
-### Build
-
-```shell
-$ forge build
-```
-
-### Test
-
-```shell
-$ forge test
-```
-
-### Format
-
-```shell
-$ forge fmt
-```
-
-### Gas Snapshots
-
-```shell
-$ forge snapshot
-```
-
-### Anvil
-
-```shell
-$ anvil
-```
-
-### Deploy
-
-```shell
-$ forge script script/Counter.s.sol:CounterScript --rpc-url <your_rpc_url> --private-key <your_private_key>
-```
-
-### Cast
-
-```shell
-$ cast <subcommand>
-```
-
-### Help
-
-```shell
-$ forge --help
-$ anvil --help
-$ cast --help
-```
+- We want to test that the data fee is adjusted for the currency, is responsive to the fallback price changing, and is responsive to an oracle.
+- Note that after these transactions go through, the updates aren't propagated until the next epoch, so we need to wait at least 15-20 seconds between transactions.
+- First, fund the owner account with ETH for transactions by calling `forge script --rpc-url [L2RPC] script/L1DataFee/FundOwner.s.sol:FundOwnerScript --broadcast`.
+- Wait approximately 5 minutes for the L1BaseFee to fall to the minimum. You can check this with `cast call --rpc-url [L2RPC] 0x4200000000000000000000000000000000000015 "basefee()"`. It should return `0x7`.
+- Run `forge script --rpc-url [L2RPC] script/L1DataFee/SendL2Tx.s.sol:SendL2Tx --broadcast` to send a transaction. Once the transaction is completed, use the tx hash to get the receipt with `cast receipt --rpc-url [L2RPC] [TX_HASH]`. The L1 Data Fee should be 16.8 billion or `0x3e95ba800`.
+- Now, let's set a fallback. Run `forge script --rpc-url [L2RPC] script/L1DataFee/UpdateFallback.s.sol:UpdateFallbackScript --broadcast`. Wait for at least 15-20 seconds for the update to push through to the oracle. Then call the SendL2Tx transaction again, and use the tx hash to get the receipt with `cast receipt --rpc-url [L2RPC] [TX_HASH]`. The fallback should be set to 11.2 billion or `0x29b927000`.
+- Finally, let's set an oracle. Run `forge script --rpc-url [L2RPC] script/L1DataFee/UpdateOracle.s.sol:UpdateOracleScript --broadcast`. Wait for at least 15-20 seconds for the update to push through to the oracle. Then call the SendL2Tx transaction again, and use the tx hash to get the receipt with `cast receipt --rpc-url [L2RPC] [TX_HASH]`. The oracle should be set to 22.4 billion or `0x53724e000`.
