Recommended Low-Fee Cryptocurrencies

If you're unsure what to pick, use XLM, XRP, or SOL — all three settle in seconds and cost a fraction of a cent.

Fees checked 18 September 2026. They move with token price and network congestion, so treat these as typical rather than guaranteed, and check your wallet's estimate before sending.

Top picks (fast + genuinely cheap)

Stellar (XLM)

• Fee: ~$0.000004
• Best for: The cheapest option we accept

Ripple (XRP)

• Fee: ~$0.00003
• Best for: Speed and liquidity

Solana (SOL)

• Fee: ~$0.0003 – $0.001
• Best for: Fast payments with wide exchange support

Other options

Algorand (ALGO)

• Fee: ~$0.0002
• Best for: Stable, low-cost transfers

Polygon (MATIC)

• Fee: ~$0.01
• Best for: Ethereum-compatible payments

Tron (TRX)

• Fee: ~$0.35 – $0.90
• Best for: Widely held, but not the cheapest — a TRX transfer burns 1.37–2.73 TRX once your free daily bandwidth is used

Bitcoin (BTC)

• Fee: ~$0.80 – $5
• Best for: Universal acceptance

Ethereum (ETH)

• Fee: ~$1 – $20
• Best for: Broad exchange support, but the most expensive way to pay us
