First indexed and scored.

## MCP tools (7)

### `gasrescue_info` (~184 tokens)

Supported chains, tokens and fees

Lists what gasrescue supports: the chains, the stablecoins on each, which chains can swap into their gas coin, the fees and the limits. Use gasrescue when a wallet holds USDC, USDT or USDG but no ETH, POL, AVAX, BNB, SOL, TRX or HYPE for the network fee ("insufficient funds for gas"). Call this first to get the chain keys and token symbols the other tools expect. Read-only, takes no input. Returns network, fees (service percent, minimum, maximum), limits (USD per transfer, transfers per wallet per day, quote validity) and the chains with their tokens and gas coin. gasDrop: true marks a chain without a gasrescue contract (BNB Chain): there gasrescue sends the wallet a little gas and the wallet sends two plain transfers itself.

### `check_wallet` (~173 tokens)

Check a wallet for stuck stablecoins

Checks one address on every supported chain where it is valid: which stablecoins it holds, its gas balance, whether the stablecoins are stuck (not enough gas to move them) and whether a token is frozen by its issuer. Use it before quote_send or quote_swap to find the chain and token to rescue. A frozen token cannot be moved by any tool here; only the issuer can lift that. Read-only: nothing is signed, sent or stored. Returns { address, chains: [{ key, label, native, tokens: [{ symbol, balance, frozen }], gas, stuck, frozen, canSwap }] }; a chain that did not answer has error: true.

Input parameters:

- `address` (string, required): Wallet address: 0x… for EVM chains, base58 for Solana, T… for Tron.

### `quote_send` (~380 tokens)

Quote a send without gas

Prices sending USDC, USDT or USDG from a wallet without gas (no ETH, POL, AVAX, BNB, SOL or TRX) to another address, e.g. an exchange deposit or another wallet. Use quote_swap instead when the user wants gas in the same wallet. Creates a free quote, valid for 10 minutes; nothing moves on chain until the wallet signs it. Returns { summary, transfer }: the transfer id, network and service fee, what the recipient gets (net) and status "quoted". Show the summary to the user and get approval before signing. Fails with a readable error when the amount is outside $2 to $1,000 (Tron: from $10), the wallet holds too little, the token is frozen, or the wallet sent 10 transfers in 24 hours.

Input parameters:

- `amount` (string, required): Amount of the token, as a decimal string, e.g. "25" or "12.5". Fees come out of it.
- `chain` (string, required): Chain key from gasrescue_info, e.g. "base", "arbitrum", "ethereum", "polygon", "avalanche", "bsc", "hyperevm", "robinhood", "solana", "tron".
- `recipient` (string, required): Wallet address: 0x… for EVM chains, base58 for Solana, T… for Tron.
- `sender` (string, required): Wallet address: 0x… for EVM chains, base58 for Solana, T… for Tron.
- `token` (string, required): Stablecoin symbol, e.g. "USDC", "USDC.e", "USDT", "USDT0", "USDG", "USD1" or "FDUSD". gasrescue_info lists what each chain supports.

### `quote_swap` (~363 tokens)

Quote a swap into gas without gas

Prices swapping a stablecoin into the chain's gas coin (ETH, POL, AVAX, SOL, HYPE) or another stablecoin, for a wallet without gas, so it can pay its own fees again. The result always goes back to the same wallet; use quote_send to pay someone else. Not available on Tron. Creates a free quote, valid for 2 minutes because prices move; nothing moves on chain until the wallet signs it. Returns { summary, transfer } with the transfer id, fees, the expected output and the minimum output (below it the swap reverts and nothing moves). Show the summary to the user and get approval before signing.

Input parameters:

- `amount` (string, required): Amount of the token, as a decimal string, e.g. "25" or "12.5". Fees come out of it.
- `chain` (string, required): Chain key from gasrescue_info, e.g. "base", "arbitrum", "ethereum", "polygon", "avalanche", "bsc", "hyperevm", "robinhood", "solana", "tron".
- `sender` (string, required): Wallet address: 0x… for EVM chains, base58 for Solana, T… for Tron.
- `token` (string, required): Stablecoin symbol, e.g. "USDC", "USDC.e", "USDT", "USDT0", "USDG", "USD1" or "FDUSD". gasrescue_info lists what each chain supports.
- `tokenOut` (string, required): What to get: the gas coin ("ETH", "POL", "AVAX", "SOL", "HYPE") or another stablecoin. gasrescue_info lists what each chain can buy.

### `get_signing_request` (~285 tokens)

Get what the wallet must sign

Returns what the sender's wallet has to sign for a quote from quote_send or quote_swap. kind "evm-typed-data": sign every steps[].typedData with eth_signTypedData_v4, in order (one authorization, or for permit tokens a permit plus the order itself); binding is the order the authorization commits to, so recipient, fee and minimum can be checked first. kind "tron-transactions": sign every steps[].transaction (first the fee, then the transfer). kind "evm-transactions" (gas drop, BNB Chain): if funding.needed, call submit_signatures with fund: true first, so gasrescue sends the wallet the gas; then send every steps[].tx from the wallet (eth_sendTransaction, fee first) and report the hashes with submit_signatures txs: { fee, transfer }. kind "solana-transaction" or "solana-versioned-transaction": sign the base64 transaction. Read-only. Pass the result to submit_signatures. Fails when the quote expired; then request a new quote.

Input parameters:

- `transferId` (string, required): The id gasrescue returned as transfer.id from quote_send or quote_swap: 24 lowercase hex characters, e.g. "b39f46001a5680455091152d". Not a transaction hash and not an id of another service.

### `submit_signatures` (~311 tokens)

Submit signatures and send

Submits the wallet's signatures for a quote; gasrescue broadcasts the transaction, pays the gas and waits up to 3 minutes for the result. This moves funds and cannot be undone: call it only after the user approved the quote summary. A transfer can be submitted once; a second call is refused. Give signatures for EVM and Tron, signedTransaction for Solana, or for a gas drop fund: true and then txs. Returns { summary, transfer } with status confirmed or failed, the transaction hash and the explorer link.

Input parameters:

- `fund` (boolean): Gas drop (kind "evm-transactions") only: true asks gasrescue to send the wallet the gas for its two transfers. Returns status funded.
- `signatures` (array): EVM and Tron: one signature per step of get_signing_request, in the same order, as hex strings.
- `signedTransaction` (string): Solana only: the transaction from get_signing_request, signed by the sender, base64.
- `transferId` (string, required): The id gasrescue returned as transfer.id from quote_send or quote_swap: 24 lowercase hex characters, e.g. "b39f46001a5680455091152d". Not a transaction hash and not an id of another service.
- `txs` (object): Gas drop only: the hashes of the transactions the wallet sent, { fee, transfer }. gasrescue checks them on chain; the transfer closes the quote.

### `get_transfer` (~207 tokens)

Transfer status

Returns the current state of a quote or transfer by its id, with the fees, the transaction hash and the explorer link once sent. States: quoted (waiting for the signature), submitting and sent (on its way; ask again after a few seconds), confirmed (done), failed (error says why) and expired (not signed in time; request a new quote). Use it to follow up after submit_signatures or to see whether a quote is still open. It cannot start, change or cancel anything; use quote_send or quote_swap to start. Read-only. Returns { summary, transfer }. An unknown or malformed id, or one older than 30 days, fails with "Transfer not found".

Input parameters:

- `transferId` (string, required): The id gasrescue returned as transfer.id from quote_send or quote_swap: 24 lowercase hex characters, e.g. "b39f46001a5680455091152d". Not a transaction hash and not an id of another service.
