⚠ Self-Custody Notice
This tool helps you monitor and interact with SNTI addresses you control.
Your private keys are never sent to or stored by this server.
XMSS keys are one-time-use — each signing retires a leaf. Keep your wallet
software up-to-date and never reuse keys.
Watch Any Address
Enter a SNTI testnet address (tsnti1…) to see its balance and UTXOs. No login required.

Generate New XMSS Address
Generate a fresh post-quantum XMSS address on this testnet node.
The address and public key are returned to you — save them securely.
To actually use this address you must run the full SNTI node software locally
or use the custodial wallet.
This is a one-time keypair generated on the server.
The server does not retain this key. Copy and save it now.
For full non-custodial control, run bitcoind locally.
Broadcast Signed Transaction
If you signed a transaction offline (using the SNTI CLI or desktop wallet),
paste the raw hex here to broadcast it to the network.
About XMSS Post-Quantum Signatures
How Assentian-PQE's signature scheme works.
Why XMSS?
✓ Quantum-resistant hash-based signatures
✓ Security based on SHA-256 alone
✓ Standardized by NIST/IETF (RFC 8391)
✓ Proven security — no algebraic assumptions
✗ One-time leaves — each key signs once
✗ Large signature size (~2.5 KB per tx)
Key Facts
Scheme: XMSS-SHA2_10_256
Tree height: 10 (1024 leaves per key)
Sig size: 2,500 bytes (5 × 500 B chunks)
Address: bech32m (tsnti1…)
PoUW v2: tree root = mining proof
Leaf index bound to block sighash
Address derivation
XMSS keypair → 64-byte public key → SHA-256 → RIPEMD-160 → 20-byte hash → bech32m encode with HRP tsnti
