Construct a signed CoW order with slippage enforcement and partner fee on Ophis. The order limits are validated against a live quote and include EIP-712 signing data.
Lists Ophis chains split into tradeable (with live orderbook) and paused (settlement deployed, no orderbook). Identifies chains to use for quoting and building orders.
Send raw JSON-RPC requests to 40+ blockchains with one endpoint, no node or API key. Use for contract reads, balances, blocks, transactions, logs, and any chain-native method.
Check live EVM transaction status and receipt by hash on Base, Ethereum, Polygon, Arbitrum, and Optimism. Verify if a transaction is mined, reverted, or pending before proceeding.
Buy and manage a global eSIM through chat. One universal eSIM for 192 countries, per-MB billing in USDT or USDC across TRON, Solana, BSC, Polygon, Optimism, Arbitrum, TON. Anonymous-flow by default — no account required.
Enables AI agents to fetch live multi-chain portfolio, token info, gas prices, and token prices across Ethereum, Base, Polygon, Arbitrum, and Optimism with a single call. No API key required.
Retrieve live gas prices for EVM chains including base, ethereum, polygon, arbitrum, optimism. Returns slow, standard, and fast tiers with priority-fee percentiles and transfer cost.
Retrieve detailed blockchain wallet portfolio balances, including native, fungible tokens, and NFTs, across multiple chains using Tatum MCP Server. Specify token types and exclude metadata for tailored results.
Verify wallet ownership of specific tokens (ERC-20, ERC-721, ERC-1155) across multiple blockchains. Provide chain name, wallet address, and token address to check ownership instantly.
Retrieve native wallet balances for up to 10 addresses at a specific block number, time, or Unix timestamp on supported blockchains using Tatum MCP Server’s API.
Calculate gas price (wei) and gas units required for transactions on multiple blockchains using a unified endpoint. Supports BNB Smart Chain, Ethereum, Polygon, and more.
Send JSON-RPC requests (eth_call, eth_blockNumber) to blockchains like Ethereum, Polygon, Base, Arbitrum, and Optimism. Supports x402 wallet auth and API key.
Retrieve all NFTs held by a blockchain address, grouped by smart contracts, for supported blockchains including Ethereum, Solana, and Polygon. Includes metadata for Solana and Algorand if fewer than 50 NFTs are held.
Retrieve detailed data for NFTs and multitokens across multiple blockchain networks. Specify the chain and collection addresses to access token information, including names, descriptions, and images. Exclude metadata or filter by token type for customized results.
Retrieve addresses of all token owners across multiple blockchains (ERC-20, ERC-721, ERC-1155) using chain name and token address, or specify tokenId for a specific NFT owner.
Retrieve metadata for NFTs or multitokens by specifying chain, token address, and IDs. Works across Ethereum, Base, Arbitrum, BNB Smart Chain, Polygon, Optimism, Celo, and Chiliz blockchains.
Retrieve multi-token balances for a wallet address across multiple blockchains, organized by smart contracts. Supported networks include Ethereum, Base, Arbitrum, Polygon, Optimism, Celo, and Algorand.
Fetches a verified contract's ABI from Etherscan on Ethereum, Arbitrum, Polygon, Base, and Optimism. Resolves proxy implementations to return the delegatee's ABI by default.
Aggregate multi-chain portfolio value across EVM chains, TRON, Solana, Bitcoin, and Litecoin. Returns total USD with breakdowns by chain, protocol, and category for one or multiple wallets.
