Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the user's wallet signature and track the transfer. Fees come out of the amount, and nothing moves without the user's signature. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Enables an agent to fetch the material a separate verifier checks — receipts, genesis documents, univocity accumulator snapshots, registration statuses and SCITT service configurations — from a SCRAPI base URL or a chain RPC endpoint you supply. Every result reports where its bytes came from and which trust-model questions they can answer, without ever choosing an operator or chain provider for you.

Query recent blockchain address data (last 14 days) for EVM, UTXO, Solana, XRP, and Kaspa networks without requiring address sync.

Enables reading and analyzing deployed EVM smart contracts by fetching bytecode, disassembling with invalid jump detection, reading storage, deriving Solidity storage slots, and decoding calldata on any EVM chain without an API key.

Enables MCP clients to interact with over 31 blockchain chains through the MoltNode RPC gateway, providing tools for chain listing, RPC calls, block numbers, and native balance queries without API keys or setup.

Enables MCP clients to search and inspect AI agents registered in ERC-8004 registries, retrieving profiles, owners, feedback, validations, and USDC-weighted trust scores without requiring a wallet or API key.

An MCP server that exposes the satring.com L402 service directory, enabling AI agents to search and query Lightning-paywalled and stablecoin-gated APIs without needing prior knowledge of their URLs.

An MCP server for Minuet — the relationship layer for ERC-8004 AI agents. Exposes Minuet's read-only API as a set of MCP tools so any MCP-compatible client (Claude Desktop, Cursor, Cline, etc.) can query the ERC-8004 agent relationship graph natively.

Algorand ecosystem knowledge layer as an MCP server, enabling identification of applications and assets, protocol discovery, name resolution, and protocol summaries without on-chain queries.

Enables AI agents to check TRON energy prices, estimate the energy a USDT transfer needs, and rent energy for a receiver under a configurable spending cap, without ever handling wallet keys. It also exposes address resource lookups, held quotes, and order status so agents can watch a delegation land on chain.

The open registry of AI agents. Every agent gets a free birth certificate (a number and a date) and can timestamp what it creates, or only its SHA-256, with an RFC 3161 timestamp and a Bitcoin anchor that anyone can verify without us. Free, no account.

Provides AI agents with direct liteserver access to the TON blockchain for querying balances, account states, transactions, and contract get-methods without HTTP gateways.

Enables AI assistants to discover and inspect Solana tokens on justi.fun, explain protocol rules and fee splits, quote trades, and build unsigned swap and launch transactions for a user's wallet to sign — without ever holding keys or sending transactions.

Enables Robinhood Chain trading agents to obtain quotes, policy-checked unsigned public-swap calldata, simulations, hook information, prices, and deployment discovery without holding keys or signing transactions.
