 - Lightweight fast-starting runtime
 - HTTP/HTTPS server
   - All HTTPS/CORS etc. features from FireFly Microservice framework
   - Configured via YAML

 - `eth_sendTransaction` implementation to sign transactions
   - If EIP-1559 gas price fields are specified uses `0x02` transactions, otherwise EIP-155
 - Makes some JSON/RPC calls on application's behalf
   - Queries Chain ID via `net_version` on startup
-  - `eth_account` support
+  - `eth_accounts` JSON/RPC method support
   - Trivial nonce management built-in (calls `eth_getTransactionCount` for each request)
 - File based wallet
   - Configurable caching for in-memory keys

-Potential future contributions:
-
-- WebSockets support
-- Tessera private transaction signing for Quorum / Hyperledger Besu
-- Loading keys on startup
-- Caching list of keys in-memory
-- Regular expression to match address anywhere in filename (depends on caching list of keys)
