Usage

Generate the snapshot Merkle Tree

mearnings -g

Generates a new earnings Merkle Tree at the L1 snapshot round. The root of this snapshot Merkle Tree will be printed.

Fetch the earnings (pending stake and pending fees) of an address

mearnings -e <address>

• <address> is an ETH address that you want to fetch earnings for

Fetches the pendingStake (the stake of the address plus any rewards) and pendingFees (the fees of the address that have not been withdrawn) for an address at the L1 snapshot round.

Verify that an address is included in the snapshot Merkle Tree

mearnings -ve <address>

• <address> is an ETH address that you want to verify is included in the snapshot Merkle tree

Verifies that an address and its earnings are included in the snapshot Merkle tree. This command will use the leaves of the snapshot Merkle Tree ( in earningsTree.JSON) to re-generate the snapshot Merkle Tree, check that the root matches the one included on-chain in the L2 MerkleSnapshot contract and that a proof of inclusion in the Merkle Tree can be computed for the address.
