How to post a transaction

• Set up the MetaMask Chrome extension and use the seed phrase corresponding to an address with funds at genesis.
• Configure the localhost:8545 network to use the Chain ID corresponding to the Catalyst chain configuration.

• Run the local testnet to confirm the transaction.
