Clear before you commit.

One exchange workspace.

Choose BTC / USD, ETH / USD, or USD / EUR from the market selector on Qualion Exchange. Trading, holdings, activity, and signed evidence stay in that workspace. Changing markets discards displayed consent and never authorizes a trade.

For crypto practice, open a portfolio with 10,000 USD-SBX, enter a quantity, review the fee-inclusive total and executable slice, then authorize. Market orders cancel any unfilled remainder. Limit orders reserve funds; you initiate later eligible slices or cancel from Activity. Funding confirmations and withdrawals are simulated.

For USD / EUR conversion, open a session and add 100 USD-SBX. Review the full-position quote, zero fee and expiry before consenting. The fixed rate is 100 USD-SBX to 90 EUR-SBX. Currency-conversion positions and crypto trading balances have distinct accounting models and are shown in their market context; they are not pooled.

All markets use nonredeemable practice balances. Prices are synthetic or fixed, with no external settlement.

A record you can keep.

Your quote, authorization, applied policy, position change and witness are connected in a signed journal. Verify a trade, inspect its history or export the evidence. Exact committed retries recover the same result without charging or exchanging again.

A session lasts 24 hours and permits up to ten exchanges. Link it to your email-verified account to keep access to the account journal after the session expires. Linking preserves the original source of earlier activity; it does not retrospectively establish who authored it.

Delegate with limits.

Use the same market yourself or authorize an agent under your account. Choose its name, market scope, amount and order limits, and duration of up to an hour for crypto, or an exchange allowance for currency conversion. The signed grant allows at most ten committed operations and 100.00 input units per exchange, within the current policy and terms. Revoke it at any time.

The agent still accepts an exact quote. Its record retains the grant and sponsor attribution. It cannot add the initial balance, withdraw, change policy or authorize another agent. A display name does not confer authority.

People govern. Records stay faithful.

Qualion administers the venue. Lyra serves as Clerk of Record within human-approved authority. The record describes what was authorized and committed; interpretation cannot change ownership or policy. A user's agent mandate and the venue's Clerk role are distinct.
