Create a new EVM or Solana wallet. Returns the wallet ID and address. Private key is encrypted server-side and never exposed.

List all wallets owned by the authenticated user. Returns wallet IDs, addresses, labels, chain IDs, and status.

Get details for a specific wallet by ID. Returns address, label, chain, spending limits, and pause status.

Get the native token balance for a wallet on a specific chain. Returns balance in both wei (or lamports for Solana) and human-readable format.

Sign a transaction with a wallet's private key. For EVM: returns signed raw transaction hex. For Solana: returns base64 signed transaction. Does NOT broadcast — use send_transaction for sign + broadcast.

Sign and broadcast a transaction. Returns the transaction hash (EVM) or signature (Solana) on success. The transaction is signed server-side and broadcast via RPC.

Send native tokens (ETH, AVAX, BNB, POL, PLS, SOL) to an address. Specify the amount in human-readable format (e.g. "0.1" for 0.1 ETH). The amount is converted to wei/lamports automatically. Signs and broadcasts the transaction.

Get the ERC-20 or SPL token balance for a wallet on a specific chain. Returns the raw balance and human-readable balance. Use get_chains to find stablecoin addresses for each chain.

Send ERC-20 tokens (EVM) or SPL tokens (Solana) to an address. Specify the amount in human-readable format (e.g. "100" for 100 USDC). Signs and broadcasts the transaction. Use get_chains to find stablecoin addresses.

Execute a read-only call against a smart contract (eth_call). Returns the raw hex result. Does not cost gas or modify state. Useful for reading on-chain data like token balances, prices, positions.

Approve a spender contract to transfer ERC-20 tokens on your behalf. Required before interacting with any DeFi protocol (DEXs, lending, etc.). Use amount "max" for unlimited approval, or specify an exact amount.

Check how many ERC-20 tokens a spender is approved to transfer. Returns the allowance in both raw and human-readable format. Use this to check if an approval is needed before a DeFi transaction.

Wrap native tokens (ETH, AVAX, BNB, POL, PLS) into their wrapped ERC-20 version (WETH, WAVAX, etc.). Required for most DeFi protocols that use ERC-20 tokens instead of raw native tokens. Specify amount in human-readable format (e.g. "0.5" for 0.5 ETH).

Unwrap wrapped tokens (WETH, WAVAX, WBNB, etc.) back to native tokens. Specify amount in human-readable format (e.g. "0.5" for 0.5 WETH).

Get the name, symbol, and decimals of any ERC-20 token by its contract address. Useful for discovering token details before transfers or approvals.

Handle an x402 payment flow. Fetches a URL, and if the server returns HTTP 402 Payment Required, parses the payment requirements, executes the on-chain payment, and retries the request with proof of payment. Returns the final response. Supports the x402 open payment standard (https://x402.org). Set max_payment to prevent overspending.

Get the current month's usage statistics. Returns operations count, tier info, remaining quota, and fees.

Buy x402 verification credits with USDC on-chain. Paywall owners need credits to process verifications beyond the free tier (1,000/month) when they don't have Stripe billing configured. Returns 402 payment instructions — pay on-chain and retry with proof.

Emergency pause a wallet. No transactions can be signed while paused.

Resume a paused wallet so transactions can be signed again.

List all supported chains (EVM + Solana) with their chain IDs, native tokens, stablecoins, and RPC configuration status.

Delete (soft-delete) a wallet. The wallet will no longer appear in listings and cannot be used for transactions.

Create an x402 paywall that charges agents/clients for accessing a resource. Returns a public access URL that returns HTTP 402 until paid. Agents pay on-chain, then retry with proof to get the content.

List all your x402 paywalls. Returns paywall IDs, names, pricing, access URLs, payment counts, and revenue totals.

Get details for a specific x402 paywall by ID. Returns pricing, access URL, payment stats, and configuration.

Update an x402 paywall configuration. Can change price, resource URL, active status, or any other field.

Delete an x402 paywall. The access URL will return 404 after deletion.

Get payment history for a specific x402 paywall. Returns verified payments with TX hashes, payer addresses, amounts, and timestamps.

Get aggregate x402 revenue statistics across all your paywalls. Returns total payments and revenue broken down by chain and token.
