How this service works
Notarize a completed DEX trade on Base (Uniswap V4, Aerodrome, Uniswap V3). Audits onchain receipt, decodes token deltas and post-swap pool state, certifies clean execution without dynamic fee gouging, and seeds the shared execution artifact for reuse dividends.
Output
Returns a certified execution artifact containing the decoded token deltas (amounts in and out), post-swap pool state for the relevant DEX (Uniswap V4, Aerodrome, or Uniswap V3), a fee-gouging clean-execution verdict, and a provenance envelope that can be reused by other agents for reuse dividends.
Example use cases
Post-trade fair execution audit
“I just made a swap on Aerodrome on Base and want to confirm I wasn't fee gouged — can you notarize tx 0x4f8e9d2a1b3c5e7f0918273645afbcde4f5a6b7c8d9e0f1a2b3c4d5e6f7a8b9c and give me a clean execution certificate?”
DeFi compliance record for treasury
“Our DAO just executed a large Uniswap V3 trade on Base at tx 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b — notarize it so we have an auditable record of token deltas and post-swap pool state for our treasury report.”
Reuse artifact seeding for agent pipeline
“Seed a reusable execution artifact for tx 0xdeadbeef1234567890abcdef1234567890abcdef1234567890abcdef12345678 from our Base Uniswap V4 swap so downstream agents can claim reuse dividends without re-auditing the trade.”
Technical details
Endpoint
POSThttps://www.tereno.xyz/api/v1/capabilities/trade.execution.notarize/invokeWhen to prefer
Choose this endpoint when you need cryptographic certification that a completed Base DEX trade (Uniswap V3, V4, or Aerodrome) executed fairly — specifically to detect dynamic fee manipulation, decode exact token deltas, capture post-swap pool state, or seed a reusable execution artifact for downstream agent workflows. Prefer it over generic block explorers when you need a typed, machine-readable provenance envelope rather than raw transaction data.
Side effects
- Invalid or malformed tx hash returns a 400 validation error
- Transaction not found on Base mainnet returns a not-found error
- Transaction is pending or unconfirmed and cannot be audited yet
- Transaction is not a recognized DEX swap (not Uniswap V3/V4 or Aerodrome) returns an unsupported protocol error
- RPC or indexer latency causes a timeout on recent blocks
- Dynamic fee gouging detected — returns a failed certification with details of the violation
- Payment not received results in x402 payment required response
