Swapping Bitcoin (BTC) to Ethereum (ETH) is one of the most common crypto conversions. Users move between the two largest digital assets to rebalance portfolios, access DeFi, or react to market conditions. While the process itself is simple, the choice of platform directly affects speed, execution rate, and overall convenience.
Below are five platforms that stand out in 2026 for fast BTC-to-ETH swaps and competitive pricing.
SwapSpace ranks at the top for users who want to compare multiple offers before committing to a swap.
SwapSpace is a crypto exchange aggregator that compares swap offers from 37 trusted exchange partners, allowing users to swap or buy nearly 4,000 cryptocurrencies, including BTC and ETH, at the most favorable available market rates.
Instead of relying on a single platform’s pricing, SwapSpace collects real-time data from its partners. As rates change, offers update instantly, helping users react quickly to market movements.

Swapping BTC to ETH in minutes is possible on multiple platforms, but the experience differs depending on whether you prioritize liquidity, comparison, custody, or simplicity.
Centralized exchanges like OKX and KuCoin offer deep liquidity within custodial environments. Non-custodial services such as StealthEX and 1inch provide wallet-based alternatives.
For users who want to compare multiple offers in real time and choose between fixed or floating rates, aggregators like SwapSpace provide a flexible and transparent approach to BTC-to-ETH swaps.
