| description | Read-only Ethereum wallet introspection — balance, ERC-20 holdings, recent transfer history for any 0x address. |
| user_invocable | true |
| args | <subcommand> [flags] |
Wraps fluxum eth-wallet for quick on-chain wallet queries from a single Claude Code invocation. No keys, no signing — pure JSON-RPC reads.
| Subcommand | Purpose | Required flags |
|---|---|---|
balance | Native ETH balance | -address 0x... |
erc20 | ERC-20 token balance | -address 0x... -token 0x... |
transfers | Recent Transfer events for the address | -address 0x... -token 0x... [-since 7d | -last-blocks N] |
All subcommands accept -rpc-url URL (defaults to https://1rpc.io/eth; override with ETH_RPC_URL env var if you have an Alchemy/Infura key).

$ARGS is everything after /eth-wallet — pass through unchanged so the user's flags reach the CLI.

-rpc-url (block-time heuristic in transfers --since assumes 12s/block — pass -last-blocks N directly on faster chains).transfers lookbacks paginate in 10k-block chunks with a 200ms pause; if you see Max_logs_per_call_exceeded, narrow the window. As of 2026-04-27: 1rpc.io/eth (default), ethereum-rpc.publicnode.com, eth.drpc.org all handle batching cleanly; eth.llamarpc.com 429s on Multicall3 follow-ups; cloudflare-eth.com errors on batches; ankr.com/eth now requires an API key.fluxum's exchange or DEX adapters.
