Diecast / Notes

What is charged

The Trade Fee: 2% of each buy and each sell. It is taken with the transfer itself, so there is no invoice, no claim and nothing to opt into. If a trade moves 1,000 DIEC, the fee is 20 DIEC. That arithmetic never varies.

What is not charged

Holding is free — a wallet that never trades never pays the token anything. Reading is free: the struck face, the supply and the Pool are public data. And there is no platform cut of any kind: no wallet collects the Trade Fee, and no share of it leaves for a team, a treasury or a founder.

The breakdown

Every fee divides between exactly two destinations, and the struck face — chosen once at construction — decides the division. Full Retire sends the whole fee to retire supply, permanently shrinking the number of DIEC in existence. Full Pool sends the whole fee to deepen the market, permanently thickening the Pool. Retire Lean, Centre Split and Pool Lean divide each fee between the two, each in its own fixed proportion. There is no third destination anywhere in the contract.

A worked example

Take a trade of 1,000 DIEC. The Trade Fee is 20 DIEC. Under Full Retire, all 20 leave circulation that block. Under Full Pool, all 20 stay in the market as depth. Under a leaning face, the 20 divide between those two outcomes — some retired, some deepening, all of it accounted for on the explorer.

Changes

The fee cannot change: there is no setter for it, nor for the split rule, nor for the supply, and there is no upgrade path that could introduce one. A different fee would require a different contract, and nothing in this one migrates. The complete statement of what is fixed lives in the Protocol Note; if a rule of Diecast could move, that document is where the movement would be written first — and it says, in plain terms, that nothing moves.
