Base Handles Nearly Half Of $3B Weekly On-Chain Bitcoin Trading Volume

Liquidity is concentrating on six chains

Roughly 97% of weekly on-chain Bitcoin spot trading volume took place across six chains, per the cited Blockworks data.

The split was narrow at the top only in theory:

• Base: about 43%

• Ethereum: 13%

• Arbitrum: 12%

• BNB: 10%

• Hyperliquid’s Layer-1 network HyperCore: 10%

• Solana: 9%

That is a liquidity sink. One venue now handles nearly half of a reported $3 billion-plus weekly flow, while the next five chains share most of the rest.

For market structure, this matters more than the headline share. Fragmented BTC wrappers and spot pools can create arbitrage, but they also create routing dependency. If the best depth is on Base, execution quality starts depending on Base infrastructure, bridge paths, pool composition and the behavior of market makers operating there.

This is not the same as native Bitcoin settlement. It is on-chain BTC trading across other networks. The distinction matters. Volume can migrate quickly when incentives, fees or routing conditions change.

Base TVL is now a macro variable for BTC DeFi

DeFiLlama data cited in the report showed Base TVL at about $4 billion, up from less than $500 million in early 2024. That is the underlying capital base supporting the network’s broader DeFi activity.

The BTC side is more stable than explosive. Total Bitcoin deployed across DeFi protocols reached nearly 80,000 BTC in 2025, then stabilized around 70,000 BTC in recent months, according to the same report.

That stabilization is important. Volume growth without a matching increase in deployed BTC can imply higher turnover, better routing, more concentrated market-making, or short-term trading demand. It does not automatically imply deeper structural adoption.

The practical check for traders is simple:

• Compare quoted liquidity against actual fill quality.

• Watch slippage on larger BTC swaps, not just headline volume.

• Track whether Base keeps share when fees or incentives shift.

• Treat wrapped BTC exposure as counterparty and bridge risk, not pure BTC exposure.

High volume is useful. It is not a substitute for settlement assurance.

Fees and activity support the Layer-2 rotation

The broader backdrop is favorable for Layer-2 execution. Stocktwits cited Fidelity Digital Assets research describing a shift toward Layer-2 networks that process transactions more efficiently and at lower cost than main networks.

Bitcoin’s own daily transaction count has reportedly stayed relatively stable in recent months, fluctuating between roughly 350,000 and 450,000 per day. Average Bitcoin transaction fees have also remained relatively low in recent weeks after occasional spikes late last year.

That creates room for BTC liquidity to move where execution is cheaper and faster. Base benefits from being an Ethereum Layer-2 developed by Coinbase and designed for lower-cost transactions while leveraging Ethereum security. It has also become one of the more active Ethereum Layer-2 networks since launching in 2023.

There is an equity-market footnote. Coinbase stock was up almost 3% at midday Monday, while Stocktwits retail sentiment around COIN remained in bearish territory and chatter stayed low over the past day. That divergence is worth noting, but it is not the core trade.

The core trade is liquidity concentration.

Verdict: Base’s 43% share is a real market-structure signal, not a yield story. Sustainable dominance will depend on whether depth persists without becoming a single-chain routing bottleneck for on-chain BTC execution.
