Automated Swap Mechanism · Ποτίδαια

Zero-Counterparty Ocean Deep Liquidity Automated Swap Mechanism on Bitcoin CashScripts that operate at fixed rates by consensus.

No order book, no liquidity pool, no maker, no slippage. The covenant is the engine.

What it is

Potidaea is the counterparty‑free swap engine on Bitcoin Cash — exchanges priced by the covenant itself, settled in a single atomic transaction.

Every backed asset carries its Bitcoin Cash backing inside its own UTXO at a rate sealed at genesis. To swap, you spend your output — the contract releases the other asset at that same backing rate. No one to match, nothing to quote, no depth to run out of.

No counterpartyNo order bookNo liquidity poolNo makerNo slippage

The mechanism is deterministic, not probabilistic. The floor is an equality the contract enforces at consensus level — not a target the market approaches.

How it works · the Universal Exchange Rate

Price is a function of genesis constants, not of market participants.

Every swap clears at rate A ÷ rate B, derived from the backing rates sealed into each asset's covenant at genesis. A one‑unit swap and a million‑unit swap clear at the identical price.

Oceanic depth
Backing is the liquidity, elastic from the moment an asset exists. 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: swaps clear at the identical price regardless of trade size. The only bound is the reservoir at a moment — never the rate.
No counterparty
No maker, no order, no human. Non‑custodial throughout — the backing lives in each UTXO and only its holder can unlock it.
Deterministic settlement
A single atomic transaction clears each swap. The contract enforces equality at consensus level — never a request to a server, never a probabilistic match.
The economics

Fees are activity‑funded, never raised. A founder earns from use, not from selling the asset.

Founder fee is sealed at genesis, 0–5%, mint‑only. Protocol fee is ~0.5% on the swap, routed to DEA holders and infrastructure. The economy pays the people whose asset is being used — not the people who issued it.

Conventional AMM
Price slips with size, maker inventory must be bootstrapped, and the LP absorbs impermanent loss on every move.
Potidaea · ASM
Price is fixed by covenant. Backing is the liquidity. No pool, no impermanent loss, no bootstrap.
Conventional order book
A trade waits for a counterparty on the other side. Thin books quote wide; thick books only exist for the most liquid assets.
Potidaea · ASM
Every asset is swappable from the moment it genesises. The Universal Exchange Rate prices every pair alone.
The name — 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. Three resonances the name earns at once: coinage, the sea as liquidity, and a city saved by water that answered when it had to. Bitcoin Cash is the liquidity.
