Network fee estimates
Compare native transfers using stored readings, then adjust an estimate. No transaction is sent.
Bitcoin estimate
Stored reading · mempool.space · observed
Fee = virtual size × sat/vB. The default 140 vB is an example; inputs and outputs determine actual virtual size.
mempool.space recommendations: Next block: 1 sat/vB · About 30 minutes: 1 sat/vB · About 1 hour: 1 sat/vB. Inclusion time varies.
USD conversion: BTC price $81,558.653418 · CoinMarketCap · observed 30m ago. The price is independent of the network fee reading.
Ethereum estimate
Stored reading · PublicNode Ethereum RPC · observed
Fee = gas units × (base + priority fee) / 1 billion ETH. Defaults: 21,000 gas for a native ETH transfer and an entered 1 gwei priority fee. Contract calls need their own gas estimate. L2 data fees are excluded.
USD conversion: ETH price $2,416.977096 · CoinMarketCap · observed 30m ago. The price is independent of the network fee reading.
Solana estimate
Reference, entered priority · Solana fee documentation
Reference fee = 5,000 lamports per signature + ceil(requested CU limit × entered micro-lamports per CU / 1 million). Legacy and v0 transactions use this signature reference. Defaults: one signature, 200,000 requested CU and zero priority price. The priority fee uses the requested CU limit, not consumed CU. This is not a getFeeForMessage quote. Account deposits, rent and instruction-specific costs are excluded.
USD conversion: SOL price $104.491888 · CoinMarketCap · observed 30m ago. The price is independent of the network fee reading.
BNB Smart Chain estimate
Stored reading · PublicNode BSC RPC · observed
Native BNB transfer only: 21,000 gas × the RPC suggested combined gas price / 1 billion BNB. The reading already combines the gas price; no extra tip is added. Token transfers and contract calls are not supported here.
USD conversion: BNB price $728.851242 · CoinMarketCap · observed 31m ago. The price is independent of the network fee reading.
Polygon PoS estimate
Stored reading · PublicNode Polygon Bor RPC · observed
Native POL transfer on Polygon PoS only: 21,000 gas × the RPC suggested combined gas price / 1 billion POL. No extra tip is added. Token transfers and contract calls are not supported here.
USD conversion: POL price $0.095534 · CoinMarketCap · observed 31m ago. The price is independent of the network fee reading.
Avalanche C-Chain estimate
Stored reading · PublicNode Avalanche C-Chain RPC · observed
Native AVAX transfer on C-Chain only: 21,000 × (RPC base fee upper bound + entered priority fee) / 1 billion AVAX. Since Helicon, the block baseFeePerGas is an upper bound, and gas charged is max(gas used, gas limit / 2). This example assumes gas used = gas limit = 21,000. It is a fee bound, not a realized quote or a contract model. P-Chain and X-Chain fees are excluded.
USD conversion: AVAX price $10.01587 · CoinMarketCap · observed 31m ago. The price is independent of the network fee reading.
Reference transfer comparison
These are different networks and fee models. Figures use each network’s defaults below; prices and network readings have separate observation times.

A fee estimate is not a transaction quote. Actual inclusion, wallet settings, account creation and contract execution can change the cost.
