Repair a failing Solana transaction: exact cause, rebuilt unsigned transaction, simulation proof, verification.

Solana transaction preview BEFORE signing: simulate an unsigned or signed legacy/v0 transaction (address lookup tables resolved) and get SOL and SPL/Token-2022 balance changes for your wallet, programs invoked (known/unknown), fee estimate and red flags (token approvals, authority/owner changes, close-to-other, wallet reassign, >90% SOL loss, simulation failure). JSON body. Optional Pre-Sign Brief

Read-only Solana financial-action firewall: decode and simulate an unsigned transaction, bind observed effects to declared intent and policy, and return a signed PASS/FAIL/REVIEW receipt

Solana swap execution for AI agents. Returns an UNSIGNED swap transaction on the best venue after fees, Jito tip and expected sandwich loss, with the plan, a simulation and the net-benefit arithmetic to verify before signing, plus the same Safe / Protect / Refuse verdict as /analyse. Needs taker: the mainnet wallet that signs and funds the trade. Never signs or holds keys. Full contract: GET /v1/a

Check an unsigned Solana transaction before signing. Send its base64 serialization; malformed input is rejected before payment. We simulate it on mainnet and return ALLOW, WARN or BLOCK with SOL and token balance changes and reasons, including dangerous approvals, owner changes, excessive outflows and redirected swaps. Solana only. The published sample is synthetic and only shows an HTTP 402 quote

Simulate one unsigned Base transaction before an agent signs it. Runs eth_call and gas estimation on current chain state, decodes the intent (ERC-20 transfer, approve, NFT setApprovalForAll), flags unlimited approvals, calldata sent to a non-contract, zero-address targets, reverts and destination risk labels such as phishing or sanctions. Returns ALLOW, WARN, BLOCK or INCOMPLETE with findings. No

Simulate and inspect an unsigned Base transaction for approvals, privileged selectors, reverts and target-code anomalies.

Check an unsigned Base mainnet transaction before signing or broadcasting. Simulates with eth_call, estimates gas, checks sender balance and target bytecode, decodes supported token transfers and approvals, flags unlimited approvals and suspicious transaction shapes, and returns PASS, REVIEW, or FAIL. Never signs or broadcasts.

Ready-to-sign, already-simulated Aero allocate() transaction for an sAERO position: the best split of Base gauges for its size (fees plus incentives, after its own dilution) as unsigned calldata for the Voter, with the cooldown, expected USD per day versus now, and warnings. Handles the contract's rules (full overwrite, exact total, ascending addresses, idle power). Never signs or sends. Base only
