Which blockchains let you receive swapped funds for under a dollar right now

The blockchains that consistently let you receive swapped funds for under one dollar are those with fixed, low gas models: Solana, BNB Smart Chain, Tron, and most layer-2 networks built on Ethereum. The reason is straightforward - network congestion, block space demand, and validator reward structures determine fees, and these chains have designed those variables to stay cheap.

You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.

The swap is carried out by an independent exchanger and the deposit address above is theirs. southkoreacoin.fun never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.

Why some chains stay cheap

A blockchain's fee is not a fixed price tag. It is a market for transaction inclusion. When many users compete for the next block, fees rise. When demand is low, fees fall. The chains that reliably stay under a dollar have either high throughput, low validator reward expectations, or both.

Solana uses a proof-of-history consensus that processes thousands of transactions per second. Its base fee per signature is around 0.000005 SOL. Even during busy periods, a standard transfer rarely exceeds a few cents. Receiving swapped funds on Solana costs almost nothing in network terms.

BNB Smart Chain runs on a proof-of-staked-authority model with 21 validators. Its gas prices are pegged to BNB's value and network load. In normal conditions, a simple token transfer costs between 0.0005 and 0.005 BNB - roughly a few cents. Swapped funds arrive with the same cost.

Tron charges fixed energy and bandwidth fees. A USDT transfer on Tron often costs under a dollar, sometimes under a cent, because the network caps resource usage per transaction. Many stablecoin swaps route through Tron for this reason.

Ethereum layer-2 networks like Arbitrum, Optimism, Base, and Polygon zkEVM batch transactions to Ethereum mainnet and settle them cheaply. Gas on these L2s is measured in gwei, but the actual dollar cost for receiving funds is typically under a dollar - often under twenty cents. The trade-off is that final settlement on Ethereum takes longer, but the receiving transaction completes on the L2 instantly.

Chains that cost more

Ethereum mainnet itself can cost under a dollar during quiet periods. But "quiet" is rare. A typical ERC-20 transfer costs $1 - $5 in gas during normal activity, and spikes to $20 or more during NFT mints or DeFi events. Receiving swapped funds on Ethereum mainnet is not reliably under a dollar.

Bitcoin's network fees depend on transaction size in bytes and mempool congestion. A standard Bitcoin transfer costs $1 - $10. SegWit addresses reduce size, but the price floor is rarely under a dollar for a confirmed transaction.

What this means for a swap

When you swap on our site, the exchanger sends the output to whichever blockchain you choose. The network fee you pay is deducted from the received amount, not quoted separately in the fee breakdown. That is the subject of the hub page, "What a crypto swap actually costs" - the spread, the network fee, and the difference between the quoted amount and what lands in your wallet are three distinct costs, and only one of them is the network fee.

Choosing a cheap blockchain for receiving funds reduces one of those three costs. It does not reduce the spread or the exchange's fee. A swap on Solana might cost you $0.01 in network fees but still lose 1% to spread. Conversely, a swap on Ethereum might cost $3 in network fees but have tighter spread on certain pairs. The total cost is the sum, not the network fee alone.

The current reliable list

As of early 2025, the blockchains where receiving swapped funds costs under a dollar in network fees are:

This list shifts. A chain that is cheap today may become congested tomorrow. A chain that is expensive today may upgrade and become cheap. The mechanism is what matters: low demand for block space relative to supply keeps fees low.

If you want to understand exactly where your money goes in a swap - not just the network fee, but the spread and the exchange's cut - read "What a crypto swap actually costs." That page explains why the number on screen differs from what arrives, and why the cheapest network fee does not always mean the cheapest total swap.
