Dex Da Costa

Dex Da Costa is a one-builder exchange on the Elysium testnet, and its numbers are the most surprising in this directory: 90,459 trades and 12,761 traders against $348.1K of all-time volume.

That works out to under four dollars a trade. The traffic is real — 12,854 wallets and 75,258 transactions in the last week alone — but the amounts are test amounts, which is exactly what a testnet exchange should look like. Its X account at 10,236 followers is large for a project described as experimental and run by a single independent builder.

Seven markets are listed, quoted against HYPE and including USDC, PURR, kHYPE and KNTQ. Four deployments sit behind them: the exchange, its factory, a wrapped HYPE token and a Uniswap V2 contract, none of them with a transaction count recorded, so the activity is attributed at the market level rather than per contract.

Twenty-nine days of daily series make this one of the longer records here.
