Tereno Aerodrome Swap Guard

x402

Tereno Aerodrome Swap Guard is a paid API for AI agents from www.tereno.xyz, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Simulates a prepared Aerodrome swap calldata against the Base blockchain to verify whether the encoded slippage/limit will be satisfied under current chain state.

How this service works

Will this prepared Aerodrome swap satisfy its encoded limit right now? Supports declared Classic and Slipstream routers, simulates on Base and returns bounded evidence. No MEV protection or inclusion guarantee.

Output

Returns bounded simulation evidence indicating whether the swap calldata's encoded price or output limit would be satisfied under the current Base chain state, along with supporting proof data. Does not guarantee MEV protection or transaction inclusion.

Example use cases

Pre-broadcast swap revert prevention

“I've got a signed Aerodrome Classic swap ready to submit — can you simulate it first to make sure the encoded minimum output limit won't cause a revert? Router is 0x6Cb442acF35158D5eda88fe602221b67A400BE22, sender is 0xDeF9876543210DEFabcdef9876543210DEFabcde, calldata is 0xd0e30db0..., and ETH value is 0.”

Slipstream route limit check

“Check whether my prepared Aerodrome Slipstream swap will pass its limit check on Base right now — the router is 0x19ceEAd7105607Cd444F5ad10dd51356716d3cf1, the from address is 0x1111111111111111111111111111111111111111, calldata is 0x12345678abcdef..., and I'm attaching 500000000000000000 wei.”

Stale quote validity guard

“My bot built this Aerodrome swap calldata a few seconds ago and I'm worried the price has moved — can you run it through a Base simulation to confirm the encoded limit is still satisfiable before broadcasting? Router 0x6Cb442acF35158D5eda88fe602221b67A400BE22, sender 0xAAAABBBBCCCCDDDDEEEEFFFF0000111122223333, calldata 0xabcdef1234..., 0 wei.”

When to prefer

Use this endpoint when you need a cheap, fast pre-flight check specifically for Aerodrome Finance swaps on Base before broadcasting, particularly when you want bounded simulation evidence tied to current on-chain state. Prefer this over generic transaction simulation tools (like Tereno Transaction Intent Guard) when the calldata is specifically an Aerodrome Classic or Slipstream swap and you want Aerodrome-aware limit validation.

Side effects

Unsupported router address — only Aerodrome Classic and Slipstream routers are accepted
Invalid or malformed calldata that cannot be decoded as an Aerodrome swap
Simulation failure due to insufficient liquidity or extreme price movement
Network or RPC errors when fetching current Base chain state
Payment not included or insufficient USDC — x402 payment required per call
Calldata exceeds maximum length (131073 bytes)
