Exavolt Chain
Verifiable AI Infrastructure

01What is Exavolt

Exavolt Chain is a Layer-1 network built for one purpose: making AI inference verifiable on-chain.

Every inference job is executed independently by two staked nodes. Both must produce byte-identical output. Results are hashed with keccak256 and compared on-chain. A job is accepted only when the two hashes match — and anyone can verify that, permissionlessly, without trusting us.

Determinism has been demonstrated across different machines, operating systems and CPUs — the same model, the same input, the same bytes.

Why two nodes

A single node can be wrong, compromised, or dishonest, and you would have no way to know. Two independent operators producing identical bytes turns a claim into evidence. Redundancy is not overhead here — it is the product.

02About EXVT

EXVT is the native gas token of Exavolt Chain. It exists to pay for computation and to compensate node operators for verified inference work.

03How to Verify

Everything below can be checked by anyone, at any time, without permission and without trusting this page.

04Quick Start

Get connected to Exavolt Chain in under 60 seconds.

Add to MetaMask (one-click)

Open your browser console or use the button on exavolt.io:

await window.ethereum.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0x2DF1C',           // 188188 in hex
    chainName: 'Exavolt',
    nativeCurrency: {
      name: 'Exavolt',
      symbol: 'EXVT',
      decimals: 18
    },
    rpcUrls: ['https://rpc.exavolt.io'],
    blockExplorerUrls: ['https://explorer.exavolt.io']
  }]
});

Deploy a contract (Remix)

Exavolt Chain is EVM-compatible. Any Solidity contract works — with one constraint: always compile with EVM Version: paris (not Shanghai/Cancun). The node's go-ethereum fork does not implement MCOPY (opcode 0x5e).

Recommended compiler settings

Solidity:       0.8.34
EVM Version:    paris       // REQUIRED — never shanghai/cancun
Optimization:   true
Runs:           200
License:        GPL-3.0

Gas

Exavolt gas is ultra-cheap. Use --gas-prices 7aexvt in CLI. For deploys and heavy transactions, set a manual gas limit (the node's --gas auto estimation sometimes under-estimates for new accounts).

# Token transfer (safe minimum)
exavoltd tx bank send FROM TO AMOUNT aexvt \
  --gas-prices 7aexvt --gas 300000
# Submit gov proposal
exavoltd tx gov submit-proposal proposal.json \
  --from DEV --gas-prices 7aexvt --gas 400000
# Note: --gas auto often under-estimates. Use fixed values above.

06Developer Principles

Known constraints of the Exavolt Chain node. Follow these to avoid common failures.

Quick checklist before deploying

✅  EVM Version set to paris (not shanghai/cancun/osaka)
✅  No string return types → use bytes32
✅  No raw call + abi.encodeWithSignature → use typed interface
✅  Guard code.length before external calls that may target an EOA
✅  Checks-Effects-Interactions pattern throughout
✅  MetaMask on network 188188
✅  Deadline param computed dynamically (block.timestamp + buffer)
✅  Gas set manually for important txs (300000-400000 safe range)

07RPC & Explorer API

JSON-RPC endpoint

Standard Ethereum JSON-RPC. Compatible with ethers.js, web3.js, viem, wagmi, Hardhat, Foundry.

# Check current block gas limit and other consensus params
curl -s https://rpc.exavolt.io/consensus_params | python3 -m json.tool

08ExavoltRegistry

The canonical on-chain directory of official Exavolt contracts. Query it to verify any contract address before interacting. Always check here — not social media or third-party sites.

Read functions

// AUTHORITATIVE: check if an address is currently official
bool ok = registry.isOfficialContract(contractAddress);
// HISTORY ONLY: every address ever registered, active or not
address[] memory all = registry.getAllContracts();
// Verify a specific contract (ethers.js)
const registry = new ethers.Contract(
  '0xA693f4790fc170933a6cBc5C7653cD4aF162D136',
  ['function isOfficialContract(address) view returns (bool)'],
  provider
);
const isOfficial = await registry.isOfficialContract(targetAddr);

Registered contracts

Always confirm with isOfficialContract() — this table is a convenience, not the source of truth.

09ExavoltSwap — Reference

ExavoltSwap is a Uniswap v2–style AMM deployed natively on Exavolt Chain. It is neutral infrastructure: any party may create a pair permissionlessly. The project does not maintain a market, does not provide liquidity, and does not quote prices.

Wrap / Unwrap EXVT

Native EXVT can be wrapped to WEXVT (ERC-20) at 1:1 with no fee. This is a utility function for contracts that require an ERC-20 interface — it does not involve any market.

10Add Exavolt to MetaMask

You only need to do this once.

11Governance

Exavolt uses Cosmos SDK on-chain governance (x/gov). Consensus parameters (like block gas limit) are managed via x/consensus module proposals.

Gov Proposal #1 — Gas Limit

# Submit proposal (JSON file)
exavoltd tx gov submit-proposal proposal.json \
  --from YOUR_KEY \
  --chain-id exavolt_188188-1 \
  --gas-prices 7aexvt \
  --gas 400000
# Vote yes
exavoltd tx gov vote PROPOSAL_ID yes \
  --from YOUR_KEY \
  --chain-id exavolt_188188-1 \
  --gas-prices 7aexvt \
  --gas 250000
# Check tally
exavoltd query gov tally PROPOSAL_ID

12Tokenomics

Fixed supply of 1,000,001,000 EXVT. Inflation permanently disabled at genesis (enable_inflation: false). No new EXVT will ever be minted.

13Security Model

Who controls the registry

Privileged roles on this chain — including ownership of ExavoltRegistry — are held by a native 2-of-3 multisig, not by a single key. Any privileged action requires two independent signatures before it executes.

The three signers are held on three independent devices with three separate seed phrases, including a hardware wallet. No single device holds more than one key. Owner management functions require consensus of the multisig itself — no single signer can make unilateral changes.

The multisig contract is 0x4545108f04D174c2C09a2A05b1bb75f84dE6F403. Its source is verified and its owners, threshold and full transaction history are publicly readable on the explorer — you do not have to take any of the above on faith.

How to verify a contract is official

Query the ExavoltRegistry on-chain:

const registry = new ethers.Contract(
  '0xA693f4790fc170933a6cBc5C7653cD4aF162D136',
  ['function isOfficialContract(address) view returns (bool)'],
  provider
);
const isOfficial = await registry.isOfficialContract(suspectAddress);
// true = official Exavolt contract
// false = NOT official — do not interact
