## MCP tools (3)

### `basic_balance` (~296 tokens)

Free balance on one chain

Free: returns the native coin balance and the main stablecoin balance (USDC; USDT on Tron) of one address on one chain. Use it for a quick 'does this wallet hold funds on chain X' check, before sending or after a payment. For all chains and tokens at once, use multichain_balances. Read-only. The address is sent to the hosted DevX API, which reads public RPCs at the latest block (one retry if the RPC rate-limits). No key, no payment. Returns: address, chains.<chain> with chain_id, block, rpc, native {symbol, raw, balance}, tokens [{symbol, address, raw, decimals, balance, stablecoin}], stablecoins_usd_face_value and ok, plus summary (stablecoin total at face value, chains_with_funds, chains_failed, note) and full (URL of the paid all-chains call). Balances are decimal strings. The stablecoin total is face value, not a market price.

Input parameters:

- `address` (string, required): EVM address (0x + 40 hex), Solana address (base58, 32-44 chars) or Tron address (T + 33 base58 chars).
- `chain` (string): Chain to read; must match the address family. Default: base for a 0x address, solana for a Solana address, tron for a Tron address.

Output parameters:

- `address` (string)
- `chains` (object): one entry per chain read
- `full` (string)
- `summary` (object)

### `multichain_balances` (~439 tokens)

All-chain balances (paid, 0.002 USDC)

Returns native and major-token balances of up to 3 addresses (at most one EVM, one Solana, one Tron) across every matching chain in one call. Coverage: native coin + USDC, USDT, DAI, EURC, bridged USDC, WETH and WBTC where they exist on Base, Ethereum, Arbitrum, Optimism, Polygon, Avalanche and BNB Chain; SOL + USDC/USDT on Solana; TRX + USDT/USDC on Tron; plus up to 10 custom tokens. Each chain includes the block number read and the response includes a stablecoin face-value total. Cost and side effects: this calls the hosted paid endpoint and costs 0.002 USDC per call via x402 on Base. It pays only if X402_PRIVATE_KEY (or EVM_PRIVATE_KEY) is set in this server's environment. It checks that the quote is USDC on Base, goes to the DevX wallet and is at most 0.01 USDC before signing. Without a key it pays nothing and returns {payment_required: true, url, quote, how_to_pay}. Use it when you need a full portfolio view or several chains at once. For one chain's native + stablecoin, basic_balance is free. Returns (paid): per-address, per-chain native and token balances with blocks, a summary and a _payment receipt.

Input parameters:

- `addresses` (array, required): 1-3 addresses, at most one per family: EVM address (0x + 40 hex), Solana address (base58, 32-44 chars) or Tron address (T + 33 base58 chars).
- `chains` (array): Limit to these chains. Default: every chain that matches the given address families.
- `tokens` (array): Up to 10 extra tokens as chain:address, e.g. base:0x4ed4e862860bed51a9570b96d89af5e1b0efefed or solana:<mint>. Tokens outside the built-in list are not discovered automatically.

### `multichain_balances_info` (~100 tokens)

Price and payment details of the paid call

Returns the URL template, price (0.002 USDC), protocol (x402 exact, USDC on Base), supported chains, payee address and docs link of the paid multichain_balances endpoint, so an agent with its own x402 client can call it directly. Makes no network request and does not pay. Returns: url, price_usdc, protocol, chains, payTo, docs, pay_with_this_package.

Output parameters:

- `chains` (array)
- `docs` (string)
- `payTo` (string)
- `pay_with_this_package` (string)
- `price_usdc` (number)
- `protocol` (string)
- `url` (string)
