Any other contract calling itself TRN is not ours.
TRN was created on Arbitrum with a fixed supply of 100,000,000. On Base, Arc and Robinhood Chain, TRN is a plain token that was also created once, with 100,000,000 and no way to make more. All of it starts in a reserve: a cold reserve that feeds a working vault.
To move TRN from Arbitrum, it is locked in an escrow contract there. The destination chain checks a cryptographic proof that the lock really happened, and only then releases the same amount from its vault. Going back returns the TRN to the vault and unlocks it on Arbitrum.
So on each chain, the TRN circulating (total supply minus what the vault and cold reserve hold) always equals the TRN locked for that chain on Arbitrum. The figures below are read from the contracts right now.
What is trusted today: the proof that a lock is inside an Arbitrum block is checked on-chain, but which Arbitrum block headers count is currently attested by a single t3rn key. Moving that to the multisig with independent attesters is planned and not done yet.
reading the escrow…
The tokens and releasers have no owner. One three-of-five multisig, the same on every chain, can pause releases (a pause lapses by itself after seven days) and moves TRN from the cold reserve to the vault within fixed limits. Returning to Arbitrum cannot be paused.
Before the fixed-supply tokens, TRN on these chains was minted against the same escrow. Those tokens are superseded and no longer traded here. Anyone still holding them can return them to Arbitrum through their original minter; until they do, they stay counted in the backing above.
