How this service works
Live multi-chain treasury balance read — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok: true, a type field set to 'wallet-ops', a receipt object containing the transaction hash, USD amount charged, and a receipt ID, and a balances object keyed by chain name, each containing ETH and USDC decimal amounts plus the RPC source URL used.
Example use cases
Cross-chain portfolio snapshot
“Can you pull my current ETH and USDC balances across Base, XRPL, and Stellar so I can see my total holdings in one place?”
Pre-transaction liquidity check
“Before I send funds, check how much USDC I have available on Base and Stellar — I want to make sure I have enough to cover it.”
DeFi bot balance monitoring
“Every few minutes, fetch my wallet balances on Base and XRPL and alert me if my USDC drops below a threshold I set.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/wallet-ops?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need wallet balances for one or more of Base, XRPL, or Stellar in a single authenticated call, especially if you are operating within the x402 micropayment protocol and want a receipt-bearing, auditable response. Prefer it over generic RPC calls when you need multi-chain aggregation with a single request and a unified receipt.
Side effects
- Invalid or unsupported chain name in the chains array returns an error
- Payment of 0.25 USDC not attached or insufficient causes a 402 response
- Network timeout connecting to chain RPC endpoint (mainnet.base.org or equivalent)
- Malformed request body missing the params or chains field
- Rate limiting or provider downtime on the underlying chain node
