How this service works
Build a ready-to-sign Solana swap that refuses to route you into a rug. Runs the full honeypot/rug scan first: buying a token whose verdict is critical (or that cannot be sold) returns the verdict and NO transaction. Returns Jupiter's unsigned versioned transaction — we never custody funds, your wallet signs. A 0.5% platform fee applies ONLY when selling into USDC/SOL; buying is fee-free. Fee is disclosed in the response and rides inside the transaction you sign.
Output
Returns a JSON object containing: a base64-encoded unsigned versioned Solana swap transaction ready for wallet signing, a risk gate verdict (allowed true/false, riskLevel low/medium/high, riskScore 0-100, flags array), embedded protocol fee details (bps, mint, account, amountAtomic), simulation error status, last valid block height, prioritization fee in lamports, swap direction, and a human-readable rationale and disclaimer.
Example use cases
Safe token exit before a dump
“I think this Solana token might be a honeypot — mint is DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263. Can you run a rug scan and, if it's sellable, build me an unsigned sell transaction for $200 worth so I can get out?”
Automated bot swap with fraud gate
“My trading bot wants to buy the token at mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — first do a honeypot and wash-trade check, and only build the unsigned buy transaction if the risk score is below 30.”
Portfolio rebalancer with risk check
“I need to rebalance by swapping $500 of this Solana token (mint: DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263) into USDC — run the full risk gate first and give me the unsigned transaction with the fee details if it's low risk.”
Technical details
Endpoint
POSThttps://soldefi.thomenz.me/v1/solana/swap/buildWhen to prefer
Choose this endpoint when you need to both build a Solana swap transaction AND gate it behind a real-time rug/honeypot risk scan in a single call — especially for sell-side exits where token sellability is uncertain. Prefer it over building a raw swap if you want an integrated risk verdict (mint/freeze authority check, wash-trade detection, sellability simulation) before committing to the transaction. Ideal for trading bots, portfolio managers, or user-facing apps that need to protect users from scam tokens without chaining multiple API calls.
Side effects
- Token flagged as high-risk: gate.allowed=false, transaction not built, verdict explains specific risk flags
- Simulation error: transaction built but simulationError is non-null, indicating on-chain execution would fail
- Invalid mint address: 400 error or empty response if token mint is malformed or not found
- Insufficient liquidity: swap cannot be routed, simulation fails
- Payment failure: x402 micropayment of $0.001 USDC not processed, 402 response returned
- Expired transaction: lastValidBlockHeight passed before user signs and submits
