Compare wallet balance on Geth and Solana

Check balance on OP Geth

cast balance 0xf0e0CA2704D047A7Af27AafAc6D70e995520C2B2  -r http://localhost:8545

Check balance on Solana using Light Client

cast balance 0xf0e0CA2704D047A7Af27AafAc6D70e995520C2B2  -r http://localhost:9090

These balances should be the same.

Do Simple Transfer

Execute simple balance transfers and then compare L2 state again

Send 2 wei from one of your wallets e.g. 0xf0e0CA2704D047A7Af27AafAc6D70e995520C2B2 to another wallet e.g. 0xa3349dE31ECd7fd9413e1256b6472a68c920D186.

npm install ethers

node -e "const { ethers } = require('ethers'); (async () => { const pk = '241bfd22ba3307c78618a5a4c04f9adbd5c87d633df8d81cfb7c442004157aba'; const to = '0xa3349dE31ECd7fd9413e1256b6472a68c920D186'; const provider = new ethers.JsonRpcProvider('http://localhost:8545'); const wallet = new ethers.Wallet(pk, provider); const tx = await wallet.sendTransaction({ to, value: ethers.parseEther('0.00000001') }); console.log(tx.hash); })()"

Compare transaction details between Geth and Solana as shown below.

Compare transaction on Geth and Solana

Fetch transaction on OP Geth (replace with your transaction hash below)

cast tx 0x0cac148ca9010016c2f5cc6edbc87d1fca31bcdeb85a1e606f0ef95d6d30f491 -r http://localhost:8545

Fetch transaction on Solana using Light Client (replace with your transaction hash below)

cast tx 0x0cac148ca9010016c2f5cc6edbc87d1fca31bcdeb85a1e606f0ef95d6d30f491 -r http://localhost:9090

These transactions should have all the same fields, for example:
