How V3 Works

Untron V3 converts provable Tron deposits into settleable EVM payouts.

The 30-second picture

  1. A depositor sends TRC-20 USDT on Tron to a deterministic receiver address (derived from a receiverSalt).
  2. On the EVM hub, a lease defines who controls routing for that salt (beneficiary/target chain/token/fees) at a given time.
  3. The hub recognizes value and creates claims (always denominated in hub USDT).
  4. Anyone can settle claims permissionlessly via fill (optionally swapping/bridging) to the lease’s payout config.

Recognition paths

There are two ways deposits/controller activity become claims:

  • Fast path: prove an individual Tron deposit directly on the hub (preEntitle).
  • Slow path: relay + process the Tron controller’s SHA-256 event hash-chain (relayControllerEventChain, processControllerEvents).

Key nouns

  • Receiver salt: stable identifier; receiver contracts can be deployed “late”.
  • Lease: time-indexed routing authority + fee parameters.
  • Claim: hub-side obligation enqueued for later settlement.
