FAQ

What is TetraChain? TetraChain is a TVM-based financial execution layer powered by the Tycho Protocol and a mesh of application-specific chains across DeFi, stablecoins, AI, and privacy How do I get gas for transactions on Tetra? TON is the native gas token for Tetra. To use the network, you must transfer TON from the TON Mainnet to Tetra using the ChainConnect bridge. This process involves locking assets on Mainnet to mint the equivalent value on the Tetra execution layer. Can I reuse my existing TON smart contracts on Tetra? In most cases, yes. Tetra is designed for "plug-and-play" compatibility with TON contracts. However, there are two key technical differences to note: Replay Protection: You must include the Tetra global_id in off-chain signatures; otherwise, the contract will reject the signature. Opcodes: Standard TON BLS (Boneh-Lynn-Shacham) opcodes are currently not implemented in the Tycho executor. If your contract relies on these, it will require a design adjustment. What is the chainId for Tetra for use in TonConnect? For developers integrating wallets or front-ends via TonConnect, the chainId for the Tetra network is 662387. How does the Tycho Protocol achieve its speed? Unlike traditional blockchains that execute transactions before reaching consensus, Tycho uses a DAG-based mempool to agree on the order of messages first. This allows nodes to produce blocks in parallel without waiting for network-wide state confirmation, resulting in thousands of transactions per second with minimal latency. Why do my tests fail when using the standard @ton/sandbox? Because Tetra has unique gas limits and configuration parameters, the standard sandbox executor will not accurately reflect the network state. You must use the @tychosdk/emulator and provide the TychoExecutor to your testing suite. How secure is the bridge between TON and Tetra? The bridge is trustless and decentralized. It does not rely on a central intermediary. Instead, it uses cryptographic Merkle proofs to verify that a transaction has occurred on the source chain before triggering the corresponding action on the destination chain. Are the block structures identical to TON? While they share the same "Bag of Cells" (BoC) logic, Tetra blocks include additional metadata for higher-precision timestamps and specific Tycho Protocol headers. Standard TON indexers may need a minor schema update to parse Tetra blocks correctly
