Free on-chain cash management missions

Three free missions let you compare a stablecoin exit, a native gas fee cap and a yield-bearing position's costs. Each mission connects one decision to a calculation with explicit assumptions, source links and interpretation limits.

The laboratory uses illustrative money and contracts. No account is required, no transaction is submitted and no entered asset balance or market price is verified.

Choose the decision you want to understand

A peg is not payroll cash

Trade the price discount against the payment deadline. Run this free mission.

Fund the fee cap

A lower final fee does not remove the upfront gas reserve. Run this free mission.

Keep what the yield earns

Measure the same assumed yield after entry, gas and exit costs. Run this free mission.

How the comparison works

A policy comparison keeps starting resources and shared conditions identical. You choose the mission's permitted policy controls, inspect the resulting calculation and revise the plan without adding imaginary funding.

Stablecoin liquidity

The redemption split changes, while balances, entered prices, fees and dated obligations stay fixed.

Native gas

The maximum fee cap changes, while the native budget, assumed base fee and entered timing remain fixed.

Net yield

The declared costs change, while the starting budget, flat annual rate and holding period remain fixed.

What a result establishes

A result establishes arithmetic under the declared model and inputs. A funded deadline is not an observed transaction; positive net income is not a forecast, principal guarantee or recommendation.

The three public missions are available without sign-in. Professional multiasset campaigns, paid access and private saved mission work are not provided by these pages.
