How this service works
Obol sells verified blockchain data over x402, settled in USDC on Base.
Output
A JSON object indicating whether the transaction was found (found: true/false), the network queried (e.g. solana-mainnet), the exact signature and slot number queried, coverage metadata (match type and maximum results), and the full transaction object if found or null if not.
Example use cases
Confirm customer payment on Solana
“A customer says they paid us in SOL — can you check if transaction signature 5KtPn1LGuxhFiwjxErkxTb7XxtLVe8tWNSBTzEGMTgCSmDNbFbYpbDymk3bS2E7t2jnKVpE at slot 200000000 on Solana mainnet actually went through?”
Audit on-chain transaction for compliance
“I need to verify that a specific Solana transaction — signature 3rFqCKq1zRGFsNoF8Z9YxEJCp4RzH8k8VxFXxNwTfVdL at slot 180000000 — exists on mainnet and get all its details for our compliance records.”
Debug failed Solana dApp interaction
“Our dApp logged a transaction signature of 2xPmYa7RkNjd9BvC4oQwELsZpFhTuWdGxMnVaKbRtHjc at slot 195000000 but users are reporting it didn't work — can you fetch the raw Solana mainnet transaction data so I can see what actually happened?”
Technical details
Endpoint
GEThttps://obol.danieldutoit.net/v1/solana/transactionWhen to prefer
Choose this endpoint when you need cryptographically verifiable, exact-match lookup of a Solana mainnet transaction by both signature and slot number. It is ideal for payment confirmation, compliance auditing, or dApp debugging where you have a specific signature and slot and need authoritative on-chain data. Prefer this over generic RPC providers when you want a paid, verified data guarantee with USDC settlement via the x402 protocol.
Side effects
- Transaction not found for given signature/slot — returns found: false with transaction: null
- Invalid or malformed transaction signature — may return error or not-found
- Slot number mismatch — transaction exists but not at the specified slot, returns not found
- Payment failure over x402 — call not executed if USDC settlement fails
- Network unavailable — upstream Solana node or Obol service outage
