Cheapest blockchain transaction fee, live across 20 L1 and L2 chains

The USD cost of one native token transaction on each of the 20 tracked chains, refreshed every 30 seconds. A native transaction is the simplest action on a chain. Send ETH on Ethereum, SOL on Solana, ADA on Cardano, XLM on Stellar, and so on. We do not yet measure ERC 20 transfers, DEX swaps or smart contract deployments. Those will ship as companion metrics in a later phase.

Eleven Layer 1 chains on the L1 tab. Ethereum, Solana, BNB Chain, Avalanche, TRON, Cardano, Sui, TON, Stellar, Litecoin and Monero. Nine Layer 2 rollups on the L2 tab. Arbitrum, Optimism, Base, zkSync Era, Linea, Scroll, Blast, Mantle and Taiko. The list matches the L1 finality and L2 block time benches so you can read cost and speed side by side.

Gas price in gwei on Ethereum cannot be compared to lamports per compute unit on Solana, stroops per operation on Stellar or sun per byte on TRON. The only honest cross chain unit is the dollar cost of a user facing action, computed at scrape time using a live USD price for each native token. Mobula's market API delivers the prices we multiply by.

Tiers exist on chains with a priority market where users can pay more for faster inclusion. Slow targets the 25th percentile of recent priority bids, standard the 50th, fast the 90th. Chains with deterministic or near deterministic fees (Cardano, Stellar, TON, TRON native transfer) emit a single tier because there is no priority market to bid into.

Solana charges 5000 lamports per signature as a hard base, plus an optional priority fee priced in micro lamports per compute unit. A simple SOL transfer uses around 200 compute units, so the priority component is typically dwarfed by the base. At current SOL prices the headline fee sits well under one cent on non congested blocks.

Cardano fees are deterministic. The protocol parameters min_fee_a per byte and min_fee_b base are set by governance and updated rarely. A standard ADA transaction is roughly 250 bytes, so the lovelace cost is essentially fixed until the next parameter vote. The USD figure on the leaderboard only moves because ADA's USD price moves.

Not yet. The figure for each Layer 2 reflects L2 execution cost only (the wallet visible gas price times 21000 gas times the ETH price). The L1 data posting fee (blob market for EIP 4844 rollups like Arbitrum, Optimism and Base after Dencun, calldata for the rest) is a separate component that varies block to block and is currently excluded. A blended total cost figure will ship in a later phase. For now use the L1 view for true wallet cost comparison, and read the L2 view as the execution component only.

Open the page. The leaderboard refreshes every 30 seconds and is sorted by cost. As a general pattern, Stellar, Avalanche, Litecoin, Solana, BNB Chain and TON cluster below one cent, Ethereum and Cardano around three to five cents, and TRON and Monero in the ten cent range. Sui sits in the low one cent range. Exact ordering depends on congestion and native token price at the moment of read.

Every 30 seconds. The harness re queries each chain's fee oracle and Mobula's price API on the same cadence, so headline values are at most 30 seconds stale plus chain RPC latency (typically under one second).

Cardano fees are protocol deterministic. Stellar's base fee is 100 stroops per operation network wide. TON's typical fee is a conservative observed value because TON has no clean fee estimate RPC. TRON native transfers consume bandwidth at the published rate per byte. None of these chains expose a priority market a user can bid into for a TRX, ADA, XLM or TON transfer, so emitting a single tier is more honest than fabricating three identical values.

Yes. Every number is a Prometheus query over a 24h window. The query string is shown in the row's hover tooltip. The harness source is open at the link in the source field below. Cite the value and the timestamp at the top of the page.
