eth_gasPrice - Viction RPC Method
Get current gas price on Viction. Essential for transaction cost estimation for gasless token operations, consumer-friendly dApps, and cost-free user onboarding.
Returns the current gas price on Viction in wei.
Why Viction? Build on the zero-gas L1 blockchain making Web3 accessible with 150 masternodes and VRC25 gasless tokens with zero-gas transactions via TomoZ, VRC25 gasless token standard, 150 masternodes, and partnerships with LayerZero and MoonPay.
When to Use This Method
The eth_gasPrice method serves these key scenarios for consumer dApp developers, teams requiring gasless UX, and builders targeting mainstream adoption:
- Set gas price for legacy transactions - Use the returned wei value as the
gasPricefield in legacy (pre-EIP-1559) transactions on Viction - Monitor network congestion - Track gas price fluctuations to determine the best time to submit transactions for lower fees
- Estimate transaction costs - Multiply gas price by estimated gas units to calculate the total cost before sending any transaction
- Build gas price oracles - Feed real-time gas price data into fee estimation UIs, automated trading bots, and wallet applications
Common Use Cases
1. Calculate Total Transaction Cost
Multiply the current gas price by the estimated gas for a transaction to determine the total cost in the native currency of Viction. This lets users see the expected fee before confirming any transaction.
import { JsonRpcProvider, formatUnits } from 'ethers';
const provider = new JsonRpcProvider('https://api-viction-mainnet.n.dwellir.com/YOUR_API_KEY');
async function calculateTransactionCost(gasLimit) {
const gasPrice = await provider.send('eth_gasPrice', []);
const costWei = BigInt(gasPrice) * BigInt(gasLimit);
const costEth = formatUnits(costWei, 'ether');
console.log(`Gas price: ${formatUnits(gasPrice, 'gwei')} Gwei`);
console.log(`Estimated cost: ${costEth} ETH`);
return costEth;
}
await calculateTransactionCost(21000);2. Build Dynamic Gas Price Strategy
Adjust gas prices dynamically based on current network conditions. During peak congestion on Viction, multiply the base gas price by 1.2-1.5x for faster inclusion; during quiet periods, use the raw gas price for the most economical confirmation.
import { JsonRpcProvider, formatUnits } from 'ethers';
const provider = new JsonRpcProvider('https://api-viction-mainnet.n.dwellir.com/YOUR_API_KEY');
async function getDynamicGasPrice(strategy = 'medium') {
const baseGasPrice = BigInt(await provider.send('eth_gasPrice', []));
const multipliers = { low: 1.0, medium: 1.2, high: 1.5 };
const adjustedPrice = baseGasPrice * BigInt(Math.floor(multipliers[strategy] * 100)) / 100n;
console.log(`Base gas price: ${formatUnits(baseGasPrice, 'gwei')} Gwei`);
console.log(`Strategy (${strategy}): ${formatUnits(adjustedPrice, 'gwei')} Gwei`);
return adjustedPrice;
}
await getDynamicGasPrice('medium');3. Compare Gas Prices Across Chains
If your application supports multiple chains, compare gas prices to route transactions to the most cost-effective network. This is particularly useful for cross-chain bridges and multi-chain DeFi aggregators.
const chains = {
ethereum: 'https://eth.dwellir.com',
polygon: 'https://polygon.dwellir.com',
arbitrum: 'https://arb.dwellir.com'
};
async function compareGasPrices() {
const results = {};
for (const [name, rpcUrl] of Object.entries(chains)) {
const provider = new JsonRpcProvider(rpcUrl);
const gasPrice = await provider.send('eth_gasPrice', []);
results[name] = {
wei: BigInt(gasPrice).toString(),
gwei: Number(BigInt(gasPrice)) / 1e9
};
}
const sorted = Object.entries(results).sort((a, b) => a[1].gwei - b[1].gwei);
console.log('Cheapest chain:', sorted[0][0], '-', sorted[0][1].gwei, 'Gwei');
return results;
}
compareGasPrices();Best Practices
- Legacy gas price is a single number: for EIP-1559 transactions, prefer using
eth_feeHistorycombined witheth_maxPriorityFeePerGasinstead - The return value is in wei: divide by
1e9to convert to gwei, which is the standard unit for gas price display - Consider current network conditions on Viction: multiply by 1.2-1.5x for faster block inclusion during congestion
- Most modern chains use EIP-1559 exclusively: check if Viction supports dynamic fee transactions before relying on legacy gas price
