"Ethereum" matching MCP tools:

  • Real-time gas price oracle for Base, Ethereum, Arbitrum, and Optimism. Returns slow/standard/fast fee tiers, estimated costs for common operations, and network congestion status. [PAID: $0.001 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]
    Connector
  • Batch multiple read-only contract calls into a single RPC round trip via Multicall3 on Ethereum mainnet (0xcA11bde05977b3631167028862bE2a173976CA11). Returns success status and raw return data for each call. Use allowFailure=true to prevent one failed call from aborting the whole batch.
    Connector
  • Returns a 0-100 Ethereum network sentiment score (composite z-scores of active addresses and transaction count vs 30-day baselines, daily since 2015) with per-component attribution, ETH network-context tiles, and methodology_version. Call when the user asks about Ethereum on-chain activity, ETH network demand heating up or cooling off, or address/transaction trends, or when timing launches, deployments, or gas-sensitive operations. Directional indicator, not a trading signal. Updates: daily.
    Connector
  • Get a wallet's individual trades on a single chain — DEX swaps (spot) or Hyperliquid perpetual trades, newest first. Wallet-centric companion to `token_dex_trades` (which is token-centric). Chain: one per call ('all'/'evm' unsupported). EVM wallets MUST pass `chain` explicitly (e.g. ethereum, base, arbitrum); non-EVM (e.g. Solana) is auto-detected. Use 'hyperliquid' for Hyperliquid perpetual trades (requires an EVM address). Call once per chain to span multiple networks. Spot columns: Time, Bought / Bought Amount, Sold / Sold Amount, Value USD, Tx Hash. Perp columns: Time, Token, Side, Action, Size, Price, Value USD, Fee USD, Closed PnL, Tx Hash. Sort (`order_by`, asc/desc): timestamp, value. Filter by `valueUsd` range. Example: { "address": "0x1f2f10d1c40777ae1da742455c65828ff36df387", "chain": "ethereum", "dateRange": {"from": "7D_AGO", "to": "NOW"} }

  • USE THIS to verify an Ethereum address before sending funds or storing it — never trust that a 0x… string is correct. Validates the format and the EIP-55 mixed-case checksum (catches typos), and returns the correctly-checksummed form. A wrong character makes a different address — funds sent there are lost.
    Connector
  • Free PREVIEW of a wallet portfolio snapshot for any public address. Returns total USD value, number of holdings, and the single largest holding. The FULL itemized holdings breakdown is available from the paid HTTP endpoint in `full_report`. chain: e.g. 'base', 'ethereum', 'optimism', 'polygon', 'solana'. address: a public wallet address (read-only; no keys needed).

  • Ethereum tools over MCP: Chainlink feeds, ENS, ERC-8004 agents, EAS attestations, transactions.

  • Ethereum MCP: Chainlink feeds, gas, ERC-20, ENS, ABI, contract calls, ERC-8004, EAS.

  • Live crypto conversion at CoinGecko prices: any coin to any coin or fiat, and fiat to coin. ?amount=0.5&from=bitcoin&to=ethereum — common tickers (btc, eth, sol…) accepted. Returns the rate, the converted amount, and the underlying prices. Prices cached ≤30s; cheap enough to call in a loop. ($0.001 per call, paid via x402)
    Connector
  • Call this when the user asks where the big options bets sit, about call/put walls, gamma exposure (GEX), the zero-gamma level, implied volatility (DVOL) or the IV term structure for Bitcoin or Ethereum. Daily snapshot of listed crypto options: top strikes by open interest, put/call ratio, dealer hedging map and ATM IV by expiry.

  • Call cc.wallet_browser_proxy — Multi-chain EVM RPC forwarder supporting Ethereum, Base, Arbitrum, Optimism, Polygon, and BSC. One endpoint, six chains. Purpose: Multi-chain EVM RPC forwarder supporting Ethereum, Base, Arbitrum, Optimism, Polygon, and BSC. One endpoint, six chains. Behavior: READ-ONLY. Does not place orders, move funds, or mutate your exchange account. Live / near-real-time data. Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.001 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 120/min (per API key). Tier: standard. Returns: Standard EVM JSON-RPC response for any method on any supported chain. Guidelines: Forward JSON-RPC only. Prefer eth_call / read methods. Sending raw signed txs is possible if you pass them — that is your responsibility. Tags: evm, ethereum, base, arbitrum, polygon, rpc, multi-chain.

  • Resolve user-facing blockchain entities into query-ready identifiers, with ambiguity kept explicit. COMMON USER ASKS: - Resolve USDC on Base - Resolve WETH on Ethereum - Resolve BAYC contract FIRST CHOICE FOR: - resolving a token symbol like USDC to token contract addresses - resolving EVM contract aliases, protocol names, pool identifiers, or Hyperliquid coin names before querying - checking which token-list addresses a symbol maps to before querying logs or transfers - turning a user-friendly token name into deterministic EVM filters WHEN TO USE: - The user names a token symbol such as USDC, WETH, DAI, or PEPE and you need contract addresses before querying raw data. - The user names a well-known EVM contract, protocol, pool identifier, or Hyperliquid ticker and you need a deterministic follow-up filter. - You need to disambiguate bridged token variants on an EVM network. - You want a source-backed token address rather than relying on memory or hardcoded constants. DON'T USE: - You already have the exact address, pool id, protocol slug, or coin filter and can pass it directly. EXAMPLES: - Resolve USDC on Base: {"network":"base-mainnet","kind":"token","query":"USDC","limit":10} - Resolve WETH on Ethereum: {"network":"ethereum-mainnet","kind":"token","query":"WETH","limit":5} - Resolve BAYC contract: {"network":"ethereum-mainnet","kind":"contract","query":"bored apes"} - Resolve Hyperliquid coin: {"kind":"hyperliquid_coin","query":"bitcoin"}

  • List the token contract addresses tracked on one platform as a list, mapping each contract to its CoinPaprika coin id. Use for 'contracts on ethereum', 'what tokens does BSC have', or to map a contract address to a coin id. Find the platformId first with getPlatforms; for one contract's live price use getTickerByContract, and for its history use getHistoricalTickerByContract. Read-only. Params: platformId (required) is a platform id such as 'eth-ethereum' or 'bsc-binance-smart-chain'; limit (optional, default 50, max 250) caps how many contracts return. An unknown platformId returns an error. No API key required.

  • Get the current price and market data of a token by its contract address (for on-chain and DeFi tokens). Use when you have a contract address (0x...) rather than a name. For history use getHistoricalTickerByContract. Read-only; platformId is the chain (e.g. eth-ethereum) and contractAddress the token address. No API key required.

  • Get the best Ethereum block builder for MEV bundle submission RIGHT NOW based on live relay acceptance rate and submission volume. Returns the top recommended builder name and acceptance percentage. Full ranked builder list with telemetry available at /intelligence/builder-recommendation with x402 payment ($0.25).

SYX is composed of 8 onchain USDC supply markets: Aave v3 (Ethereum, Base, Arbitrum), Compound v3 (Ethereum), and Morpho v2 Prime USDC vaults from Steakhouse Financial and Gauntlet (Ethereum, Base). Use this when the user asks what is inside SYX, or wants to see the per-component breakdown.
