Eterna, documented as it ships
Notes on Eterna Hybrid Exchange as it ships: fee mechanics, the EHX payback model, machine execution via MCP, and how the venue compares to the alternatives. Every figure is checked against primary documentation and dated, because this product moves fast.

Eterna is developing fast, and a fee page that silently goes stale is worse than no fee page. Every post carries a publication date and a last-verified date, and every number is traceable to a primary source listed at the bottom of the post.
When Eterna changes a fee, ships a product, or revises the payback mechanism, the affected post is updated and re-dated rather than quietly patched. Where a claim cannot be verified in official documentation, it is not published here — including the widely repeated one about a signup bonus for new users, which does not exist.
