# Solana Transaction Explainer

> Solana Transaction Explainer is a paid API for AI agents from token-safety.50to50k.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Decodes a Solana transaction signature into a human-readable summary including status, kind, program names, SOL/token transfers, net balance changes, fee, signers, and memo.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solana-transaction-explainer-728753c3
```

Example prompt: Can you explain what happened in this Solana transaction — signature 5KtPn1LGuxhFiwjxErkxc9TfzLGNNqkDrmPAzL69BqJhf7mR4vQkXn8xJpWqMiPbG1rCpCZzQbHPpSLMzVJ9kgH — tell me if it succeeded, what kind of transaction it was, which programs were involved, and what the net SOL and token balance changes were?

## When to prefer this

Choose this endpoint when you need a comprehensive, human-readable breakdown of any Solana transaction from just its signature — especially useful for debugging failed transactions, auditing DeFi activity, verifying transfers, or building user-facing transaction history UIs. It is preferable over raw RPC calls when you need named programs, readable errors, net balance deltas, and a natural-language summary all in one response without parsing low-level Solana transaction structures yourself.

## Known failure modes

- Invalid or malformed base58 signature returns an error
- Transaction signature not found on-chain (e.g. expired or wrong network)
- Network timeout or RPC node unavailability causing fetch failure
- Very large or complex transactions may have incomplete program name resolution
- Payment failure (x402) if USDC balance insufficient for the $0.01 per-call fee

## How this service works

Solana transaction explainer: status and readable error, kind (transfer, swap, failed, other), one-sentence summary, named programs, SOL and token transfers with owners, net SOL and token balance changes per account, fee, signers and memo, from a transaction signature.

## Output

Returns a structured breakdown of the transaction including: success/failure status with a readable error message if applicable, transaction kind (transfer, swap, failed, or other), a one-sentence plain-English summary, list of named programs invoked, individual SOL and token transfers with source/destination owner addresses, net SOL and token balance changes per account, transaction fee in lamports, list of signers, and any attached memo.
