Decentralized Exchange

Order book plus AMM over one engine. Nostro-Vostro settlement, unified USD on Bitcoin Cash.

The venue where the market emerges — price by participants, settlement by covenant.

What it is

Anthemus is the decentralized exchange on Bitcoin Cash — a venue for the parts of the economy a covenant can't price alone.

Token-class assets, wrapped foreign coins, cross-chain pairs — Anthemus handles everything Potidaea cannot. Price emerges from participants; settlement is still on-chain, atomic, non-custodial.

Three interfaces, one engine

The same covenant backs three surfaces, each matching a different kind of flow.

Swap
Instant two-asset exchange priced by the on-chain pool. Best for small-to-mid clips where latency matters more than slippage control.
Exchange
Full order book — place a limit, wait for a taker, cancel at will. Best for sizes where the mid price would move you.
Deposit
The rail into unified USD. Stablecoins come in as asset × chain pairs, correspondent-settled, and land as unified USD on your Bitcoin Cash address.
Withdraw
The mirror of Deposit. Pick asset + destination chain; the correspondent swaps unified USD out at the market rate, settles on the target rail.
Unified USD — one USD, many entry rails

USDT, USDC, PYUSD on five chains stop being five different assets. They become one asset — USD — on Bitcoin Cash.

The pair matrix collapses: no USDT/USDC price, no USDC-Base vs USDC-Arbitrum price. Entry chain is a rail, not an asset. Correspondents handle the lock-and-mint; the trader sees one row.

The pair you trade is EUR/USD or BCH/USD, not the twenty cross-chain variants of each. The correspondent system does the matrix-flattening on your behalf.

Under Agora, beside Potidaea

Two markets under one roof. Different engines, complementary coverage.

Anthemus · DEX
Price emerges from participants. Order book + AMM + Deposit rail. For token-class, cross-chain, unified USD.
Potidaea · ASM
Price is the mechanism. Backed assets swap at the Universal Exchange Rate — covenant-priced, zero slippage, no counterparty.

No single mechanism prices every asset well. Backed assets want the covenant; token-class and cross-chain assets want a market. Agora holds both.
