# VinuChain Mainnet

VinuChain mainnet is the production network (chain ID `207`). This section covers connecting a wallet to mainnet and running mainnet nodes.

{% hint style="danger" %}
**Completed upgrade — activated 29–30 August 2026.** Mainnet has moved to testnet's target feature set: the **ELEMONT** release activated SfcV2, Shanghai, Cancun, Prague (EIP-7702 set-code transactions), the Elemont consensus fixes, the BLS12-381 and latest-EVM precompiles, and PaybackV2. The binary also adds `vc_getPaybackBalance` and `eth_config`/`vc_config`; core `vc_*` RPC methods are already live.

**Node operators must be running the ELEMONT binary** — this is a consensus upgrade. See the [Mainnet Upgrade Guide (ELEMONT)](/vinuchain/technical-docs/vinuchain-mainnet/chain-upgrade-guide.md); pre-flight checks need lead time, especially transaction-index recovery. Container deployments also require their coordinator-approved image/deployment runbook.

**Fee-refund stakers must migrate** to a new Payback contract — see [the migration steps](/vinuchain/technical-docs/vinuchain-mainnet/elemont-upgrade.md#if-you-stake-in-the-payback-fee-refund-contract).

Mainnet now runs the full ELEMONT rule set (`Berlin`, `London`, `Shanghai`, `Cancun`, `Prague`, `VinuBLS12381`, `VinuLatestEVM`, `Llr`, `Podgorica`, `SfcV2`, `Elemont`, `ElemontPubkeyValidation`, `PaybackV2`) on the V2 staking contract.
