How this service works
HostDeFi is a Solana DEX with a free token safety scanner. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, 1% flat fee.
Output
A standard JSON-RPC 2.0 response object containing the 'id' matching the request, 'jsonrpc': '2.0', and a 'result' field with the blockchain data requested (e.g. a hex block number, balance, slot integer, transaction object, or receipt). Errors return a standard JSON-RPC error object.
Example use cases
Check current Solana slot height
“Query the current Solana slot number using the HostDeFi RPC — I need to know how far along the chain is right now without spinning up my own node.”
Read EVM wallet balance on Arbitrum
“Use the HostDeFi multi-chain RPC to call eth_getBalance for wallet address 0xAbC...123 on Arbitrum and tell me the current balance in wei.”
Fetch transaction receipt on Polygon
“I just submitted a transaction on Polygon — can you call eth_getTransactionReceipt for tx hash 0xDef...456 via the HostDeFi RPC gateway and let me know if it confirmed?”

Choose this endpoint when you need pay-per-call, no-subscription RPC access to EVM chains or Solana without managing API keys or committing to a monthly plan. It is well-suited for agents that need sporadic blockchain reads across multiple chains via a single unified gateway with x402 micropayment billing.
Side effects
- Unsupported method name rejected by allowlist upstream — returns JSON-RPC error
- Invalid chain path parameter returns 404 or routing error
- Payment not included or insufficient USDC triggers x402 payment-required response
- Malformed params array causes JSON-RPC parse error
- Network congestion on target chain causes delayed or timeout response
