MoltNode by Chord
Read 31 blockchains over JSON-RPC and swap via Chord: best route, unsigned tx, simulation. No key.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢list_chains
List every chain MoltNode serves (slug, name, chainId, family, native coin, endpoint) and which ones Chord trades on. Call this first for valid chain slugs.

"type": "object",
"properties": {},
"required": [],

}🔴rpc_call(chain, method, params)
Call any JSON-RPC 2.0 method on a chain through MoltNode, no API key. EVM chains use eth_* methods; Solana and Sui use their own.

}🟢chord_find_token(chain, query)
Find a token by symbol, name or address on a chain Chord trades on (base, ethereum, monad, bnb, avalanche, arbitrum, robinhood, arc). Returns addresses, decimals and whether the token is verified; similar tickers are common, so compare addresses.

}🟢chord_swap_quote(chain, tokenIn, tokenOut, amount, taker, ...)
Best swap route from Chord (getchord.xyz) across the DEXs of the chain, with the UNSIGNED transaction to sign, the ERC-20 approval it needs (as a ready transaction) and a simulation run from the taker wallet. Amounts are integer strings in the token's smallest unit; the zero address is the native coin. Nothing is sent: sign with your own key, then send_raw_transaction.
