Tempo Fee-Sponsorship & Gas-AMM Economics

Model Tempo's enshrined-AMM gas cost in any major stablecoin plus server-paid fee sponsorship, vs card/SWIFT/ACH baselines. Distinct from Arc ERC-4337 Paymaster — Tempo has no native gas token and uses an enshrined protocol AMM.

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.
Architecture note: Tempo uses an enshrined protocol-level AMM to settle gas fees in stablecoins — not the ERC-4337 Account Abstraction Paymaster architecture used by Arc (ART-46). Server-paid sponsorship here means the protocol operator absorbs a portion of the enshrined AMM gas cost, not a smart-contract paymaster.
Staleness note: this model's flat per-tx gas constant, $0.0003, predates Tempo's mainnet launch and is not TIP-1010 verified. TIP-1010's published mainnet base fee targets close to $0.001 for a standard TIP-20 transfer, over three times this model's constant. For a mainnet-accurate, TIP-1010-cited fee calculation, use art-389-tempo-mainnet-fee-capacity, the successor node.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `model_tempo_gas_economics`. Task: Model Tempo enshrined-AMM gas cost across fee-stablecoin mix with server-paid sponsorship, vs card/SWIFT/ACH baselines.
Call it with arguments: {"policy_parameters":{"monthly_volume":100000,"fee_mix":{"USDC":0.7,"USD1":0.2,"PYUSD":0.1},"amm_slippage":{"USDC":0,"USD1":2,"PYUSD":5},"server_paid_pct":0.15,"baseline_rail":"swift","tx_amount_usd":1000,"impl_months":3}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
