Ethereum Integration

TODO: Write content for this page.

Interact with Ethereum and other EVM chains from ICP canisters. Cover the EVM RPC canister (7hfb6-caaaa-aaaar-qadga-cai), JSON-RPC calls to Ethereum nodes, multi-provider consensus, generating Ethereum addresses with threshold ECDSA, signing and submitting transactions, reading ERC-20 balances, and cycle costs for RPC calls. Compare direct RPC vs HTTPS outcalls approach.
