FAQ
Is this mainnet?
No. Public docs target c12-testnet-1. Mainnet is planned. Testnet tokens have no monetary value.
What chain id do I use?
| Network | CometBFT | EVM |
|---|---|---|
| Testnet | c12-testnet-1 | 12121 (0x2f59) |
| Local devnet | c12-devnet-1 | 1212 |
Can I write environmental records from Solidity?
Not via EVM today. Writes use Cosmos MsgIssue and related messages. EVM IC12 is read-only.
Does the explorer verify Solidity?
Not yet supported (planned). Use the manual bytecode method in Verifying contracts.
Where is the testnet seed?
P2P 52.6.69.73:26756. Build persistent_peers as {node_id}@52.6.69.73:26756 after reading the node id from the seed’s /net_info — see Running a node.
Where are seeds for state sync?
The chain repo documents state sync SDK flags but does not ship a testnet state sync runbook. Use genesis + P2P sync, or operator-published state sync when available.
What minter key does Zevo use on fixtures?
p:zevo-integrator in devnet/testnet genesis fixtures — do not reuse published hex keys on the public internet.
Does C12 verify physical meters on-chain?
No. The chain stores structured quantities and runs checking rules; it does not claim direct physical verification (see ADR-0019 comms policy in chain repo).
How do I report a security issue?
Email security@carbon12.network (PGP TBC). Details: Security.
Where is token price or sale info?
This site intentionally excludes price, sale, or listing language for testnet tokens. Economics are subject to change; see chain ADR-0002 for the Path B model.
