Workflow

Offramp

The customer deposits an asset into the Trading API. Bitrus pays out MXND to a Bitrus-controlled burn wallet, the MXND backend burns it, and SPEI disperses MXN to the customer's CLABE.

Each trade

Quote USDT/MXND on the Trading API

Pair is USDT/MXND, side SELL. The total field is the MXN amount the customer will eventually receive (before any fixed off-chain fees on the SPEI leg, if any apply).

Customer sends USDT to the deposit address

Standard on-chain transfer. Bitrus waits for chain confirmations and moves the order through WAITING_DEPOSIT → DEPOSIT_RECEIVED.

4

Trading API sends MXND to the burn wallet

We sign and broadcast the outbound MXND transfer to the whitelisted withdraw address — which is a Bitrus burn wallet. The order reaches ASSET_SENT → COMPLETE on the Trading side.

5

MXND burn + SPEI dispersion

The handler opens a BURN Operation and waits for the dispersion. Final state: Operation COMPLETED and the customer's notification_emails get burn_confirmation.
