Theo tokens live on multiple chains. Cross-chain transfers use LayerZero's OFT standard.
Where Each Token Lives
Token | Ethereum | Arbitrum | Base | Stable | HyperEVM |
thUSD | ✅ (primary) | ✅ | — | ✅ | — |
sthUSD | ✅ (primary) | ✅ | — | ✅ | — |
thBILL | ✅ (primary) | ✅ | ✅ | — | ✅ |
The Theo app at app.theo.xyz displays Ethereum, Arbitrum, and Stable in its network switcher. thBILL on Base and HyperEVM is accessible through external DeFi protocols (Morpho, Pendle, Hyperliquid).
Ethereum-Only Operations
These actions require your tokens to be on Ethereum mainnet:
Minting and redeeming thUSD or thBILL
Staking thUSD → sthUSD
Unstaking sthUSD → thUSD
If your tokens are on another chain, bridge to Ethereum first.
Bridging
Bridge through Stargate Finance or other LayerZero-compatible interfaces. Tokens are locked on the source chain and minted on the destination chain via LayerZero messaging. Transfers are near-instant.
Gas fees apply on both chains. Always verify the destination chain and address — cross-chain transfers are irreversible.
