How this service works
Executes state-override simulation of $1k, $10k, and $50k swap orders on Base Mainnet, calculating exact slippage, gas overhead, and MEV frontrun exposure.
Output
Returns a cryptographic simulation proof with exact slippage percentages, gas overhead figures, and MEV frontrun exposure metrics for $1k, $10k, and $50k swap orders simulated via state-overrides on Base Mainnet, without executing any real on-chain transaction.
Example use cases
Pre-trade MEV exposure check
“Before I buy $50k of this new Base token, can you run a swap simulation to show me exactly how much slippage I'd get and whether MEV bots could sandwich my trade?”
Comparing swap safety across order sizes
“Run swap simulations for $1k, $10k, and $50k orders on this Base token and show me how slippage and gas costs scale — I want to know if bigger buys are getting hit harder.”
DeFi bot pre-execution validation
“Before my trading bot executes this $10k swap on Base, run a state-override simulation to confirm the slippage is under 3% and MEV frontrun exposure is low — give me the proof.”
Technical details
Endpoint
POSThttps://rugshield-402.onrender.com/v1/audit/swap-simulation-proof?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise, cryptographically-provable swap simulation data on Base Mainnet across three order sizes simultaneously — particularly when MEV frontrun exposure and exact gas overhead are needed before executing a real trade. Prefer this over generic slippage estimators when you need state-override accuracy rather than approximations, or when auditing a token's tradability for large orders.
Side effects
- Invalid or unsupported token contract address returns an error
- RPC state-override failure if Base Mainnet node is unavailable
- Malformed POST body or missing required fields returns validation error
- Token with no liquidity pool may produce no simulation result
- Payment of $0.02 USDC not processed results in 402 rejection
