Tea Scripts

This repo contains scripts to run on a local devnet of the Layer Tea network to verify the network's functionality.

Prerequisites

• Clone the this repo.
• Clone the GPG Wallet Repo and checkout audit-fixes branch.
• Clone the Optimism Repo and checkout audit-fixes branch.
• Clone the Tea Geth Repo and checkout audit-fixes branch.
• Manually edit the IsTea() function in tea-geth to return true.

Setup Devnet

• Run a local devnet, and save the L2 RPC URL.
• Set export PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 in your environment (this corresponds to a prefunded address on the devnet)
• Set export OWNER_PRIVATE_KEY=??? in your environment (this is the address who can update the fallback price and oracle)
• Set export L2_RPC_URL=http://localhost:9545 (or another URL, if it's different) in your environment.
• Run the Deploy.s.sol and Airdrop.s.sol scripts on the GPGWallet repo (you must use the same PRIVATE_KEY for these transactions so signatures are consistent).
  • forge script --rpc-url $L2_RPC_URL script/Deploy.s.sol:DeployScript --broadcast
  • forge script --rpc-url $L2_RPC_URL script/Airdrop.s.sol:AirdropScript --broadcast

GPG Wallet Script

• 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 the AddSigner.s.sol script in this repo:
  • forge script --rpc-url $L2_RPC_URL script/GPGWallet/AddSigner.s.sol:AddSignerScript --broadcast
• Verify that the transaction succeeded and the terminal output confirms the signer was added

L1 Data Fee Script

• 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:
  • forge script --rpc-url $L2_RPC_URL 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.
• Then, send the first transaction:
  • forge script --rpc-url [L2RPC] script/L1DataFee/SendL2Tx.s.sol:SendL2Tx --broadcast
  • 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:
  • 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.
  • Repeat SendL2Tx: forge script --rpc-url [L2RPC] script/L1DataFee/SendL2Tx.s.sol:SendL2Tx --broadcast
  • 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:
  • 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.
  • Repeat SendL2Tx: forge script --rpc-url [L2RPC] script/L1DataFee/SendL2Tx.s.sol:SendL2Tx --broadcast
  • 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.
