How this service works
Simulate a Solana transaction for agents about to sign it: balance changes, labeled programs, deterministic risk rules, and a proceed/caution/avoid recommendation. Accepts USDC on Base or Solana. Category: data.
Output
Returns simulated balance changes per token and wallet, a list of labeled programs involved in the transaction, deterministic risk rule evaluations, and a top-level recommendation of proceed, caution, or avoid — enabling agents to make informed go/no-go decisions before committing to signing.
Example use cases
DeFi swap pre-flight safety check
“I'm about to execute a token swap on Solana — can you simulate this transaction first and tell me what my balance changes will be and whether it's safe to sign? Here's the base64 transaction: AQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABAAQADiP...”
NFT mint transaction risk review
“I got sent this Solana transaction to mint an NFT but I'm not sure I trust the source — simulate it for me and give me a risk verdict before I put my signature on it. Base64 transaction: AQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...”
Agent pre-sign guardrail in DeFi bot
“My trading agent is about to sign a Solana transaction automatically — run a simulation first, flag which programs it calls, show the expected balance deltas, and tell me if it should proceed or abort. Transaction: AQAAAAAAAAAAAABhHIU4yCDxyz...”
Technical details
Endpoint
GEThttps://agentforge-taupe.vercel.app/v1/solana/tx-simulate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent or user needs a safety gate before signing any Solana transaction — especially in automated DeFi, trading bots, or wallet UIs where blind signing is a risk. It is preferred over manual inspection or generic decoders because it combines simulation, program labeling, and a deterministic risk recommendation in one call. Use it as a pre-sign guardrail rather than a post-execution explainer.
Side effects
- Invalid or malformed base64 transaction returns a parsing error
- Simulated state may diverge from actual chain state if recent blocks altered account balances
- Very complex transactions with many instructions may time out
- Transactions referencing unknown or unlabeled programs may produce incomplete risk assessments
- Payment failure (non-USDC or wrong chain) results in 402 rejection
