Become a smart meter
for five minutes.
Your browser generates an Ed25519 key locally, registers only the public key, signs meter readings, submits them through the real Device API and builds a real TDAP Merkle batch. Temporary identities expire after 24 hours.
Create temporary device
The private key stays inside this browser tab. It is not uploaded or saved by TWIX.
Send signed meter readings
Build the Merkle commitment
All unbatched readings from your temporary identity are converted into one domain-separated SHA-256 Merkle root.
Anchor it to TWIX Mainnet
The TDAP anchor contract has not been configured yet. The full signing, ingestion, storage and Merkle proof pipeline still works; on-chain anchoring will activate here after the contract is deployed.
Temporary means temporary.
The playground identity is for learning and integration testing only. Production device identities should be created and protected on the meter, gateway, HSM or secure element—not in a browser.
