Tavchain Testnet uses the Cronos-derived Cosmos SDK application and CometBFT-family consensus to execute an EVM-compatible ledger. Applications interact with that ledger through Ethereum JSON-RPC.

Network identifiers

Wallets sign for EVM chain ID 771002. Native nodes identify the chain as tavchaintestnet_771002-1. The network reference lists the current endpoints and genesis identity.

Consensus participation

The initial validator set is under shared administration. Only active validators vote on blocks. Running a full node or holding Test TAV does not enroll an account as a validator. Validator membership and voting power are chain state and can change. Do not infer consensus power from a wallet’s TAV balance or assume every validator has equal power.

EVM execution

Tavchain executes Ethereum-style contract bytecode. Use Solidity and the documented development tools. The chain ID, gas, account nonce and transaction signature identify how an EVM transaction is processed. EVM compatibility does not imply that every upstream module, opcode revision, precompile or integration is enabled. Refer to release capabilities and the settings in each guide.
