Your BSC address (receives WXDN)
Email for confirmation (optional)
We send one confirmation email when your WXDN is delivered, plus a notification if your session expires with an insufficient deposit (so you know to contact support — do not send more funds to an expired session).
A unique XDN deposit address is generated for your session (60-minute window). Send XDN to that address — bridge maps it to your BSC destination via sub-address database. No OP_RETURN memo needed.
⚠ Important: Multiple deposits supported — they combine automatically until the requested amount is reached. Significant overpayment (above 2× the requested amount) is automatically refunded to the sender. If you send less than required and the session expires, your deposit is refunded minus a small processing fee. Do not send from an exchange wallet — refunds go to the sending address.

Address prefixD-prefix addresses (mainnet)
Block time~60 seconds
Per-session deposit addressesEach bridge session is allocated a fresh, independent XDN address — there is no shared key derivation between sessions.
Security Model
Double-mint preventionSQLite UNIQUE constraints prevent any deposit from creating more than one bridge job, regardless of restart or retry behaviour.
Supply balanceTotal XDN + WXDN supply is constant. Wraps lock XDN in the custodian and mint WXDN from a fixed reserve; unwraps burn from the reserve and release the same amount of XDN.
Key isolation — XDN custodianEncrypted wallet, decrypted only at signing time, held outside the bridge process. The bridge has no ability to move custodian funds without the daemon's cooperation. Ownership is validated at startup; the bridge refuses to run on mismatch.
Key isolation — chain operatorsHeld in daemon memory only, never written to logs or transmitted off-host. Daemon runs as an unprivileged user with OS-level sandboxing.
Host hardeningServer is hardened in line with current security best practices.
Session expirySub-addresses are de-monitored after 60 minutes if no deposit detected — the operator never holds funds indefinitely.
Refund routingRefunds go to the sending address by default. Override addresses can be set per-session for EVM chains.
