Automated Swap Machine

Potidaea

Zero-Counterparty Ocean Deep Liquidity Automated Swap Machine on Bitcoin Cash. Consensus enforced fixed rate operations, zero contentions. No order book, no liquidity pool, no maker, no slippage. The covenant is the engine.

The mechanism
A swap with no other side of the trade.

Every backed asset carries its BCH backing inside its own UTXO. To swap, you spend it — the contract releases the other asset at the fixed backing rate. There is no one to match, nothing to quote, no depth to run out of. Only the reservoir bounds quantity at a moment; it never moves the rate.

Oceanic depth

Backing is the liquidity, elastic from moment zero. No bootstrap, no LP, no thin pairs — MBA↔MBA depth is there the instant an asset exists.

Zero slippage, any size

The rate is fixed by consensus: out = in × backingRate. A 1-unit swap and a million-unit swap clear at the identical price.

No counterparty

No maker, no order, no human. Non-custodial throughout — the backing lives in each UTXO and only its holder can unlock it.

Ποτίδαια

Ποτίδαια — the city of Poseidon. A Corinthian colony founded around 600 BC at the narrowest point of the Pallene peninsula in Chalcidice, northern Greece. The city held the sea-god in such regard that its early coinage was minted featuring Poseidon carrying his trident. Herodotus records the city was saved from the Persian siege of 479 BC by a tsunami, attributed to Poseidon's intervention.

The name is apt on three counts: it is a place / settlement — a venue and a hub, not just a deity; it is literally tied to minting money — Poseidon on its coins; and it carries the sea / decisive-tide association.

Applied to a mechanism: MBA↔MBA depth is infinite from moment zero; the elastic-mint reservoir replaces bootstrap, seeding, thin pairs and the whole slippage vocabulary.

Bitcoin Cash is the liquidity.

How it works
Redeem and claim, composed atomically.
1

Redeem the source

Your MBA is self-backed — a P2PKH spend releases the BCH locked inside it, at peg. No fee, no oracle, no contract path.

2

Claim the target

That BCH funds a claim() against the target's reservoir, minting units at its fixed rate — the covenant enforces the backing on every output.

3

One transaction

Redeem + claim settle together in a single atomic tx. It either completes whole or not at all — BCH↔MBA and MBA↔MBA alike.

Economics · the equilibrium flywheel
Counterparty-free isn't fee-free — the fee builds the floor.

Every mint/swap mints a small protocol fee. The majority routes to holders of the flagship DEA (the Deviant Equilibrium Asset), pro-rata and time-weighted. Demand for it deepens BCH backing, which lifts the floor under every asset at once.

DEA holders · 0.3%
platform · 0.2%
Protocol fee today 0.5% → majority to holders. Future: 0.3%, 100% to holders (the cut comes out of the platform slice — holder yield is unchanged).
01

Any asset's swaps mint a 0.5% fee — Stoa, Olympia, or unlisted.

02

The majority routes to DEA holders, pro-rata + time-weighted.

03

DEA demand rises → its BCH backing deepens → the floor lifts.

04

A higher floor lifts every MBA at once. Success is shared.
