Testing utilities

reth-tester

Reth node that uses ExEx & Etherscan to fill the in-memory chain and stop.

By passing --against-rpc $URL it will verify the local RPC responses to the remote one starting a STORAGE_TIP - 1 to TIP.

cryo_test.sh

Runs cryo commands on two nodes to check correctness and compare timings. Modes:

1. No BLOCK_START & BLOCK_END: Uses in-memory range of the first node (BLOCK_START = STORAGE_TIP - 1, BLOCK_END = chain tip).
2. With BLOCK_START & BLOCK_END: Compares nodes using the provided range.
