Ethereum finished June 30, 2021 with a notable 5.2% gain at $2,276, sharply outperforming Bitcoin which declined 2.3% to $35,046 on the same day. The divergence came amid growing anticipation for the upcoming London hard fork and its flagship feature, EIP-1559, which reached a key testnet milestone just days earlier on June 24.
TL;DR
- ETH gained 5.2% on June 30 while BTC fell 2.3% — a notable divergence
- EIP-1559 testnet went live on June 24, with the first block mined successfully
- DeFi tokens rallied: COMP +8.7%, AAVE +5.4%, BAL +9.2%, MKR +11%
- DEX volumes dropped 50% in June to $68B, but Polygon surged ahead
- ETH down 48% from its May 12 ATH of $4,380 but Q2 still up 18%
EIP-1559: The Fee Revolution Approaches
The Ethereum Improvement Proposal 1559 represents one of the most significant changes to the network’s economics in its history. Set to deploy as part of the London hard fork, EIP-1559 will overhaul the transaction fee market by introducing a base fee that is automatically burned rather than paid to miners. Users will only pay a voluntary priority fee (tip) to incentivize inclusion.
On June 24, Ethereum lead developer Tim Beiko confirmed that the first EIP-1559 block had been successfully mined on the testnet, marking a critical milestone toward mainnet deployment. The upgrade promises to make gas fees more predictable and could introduce deflationary pressure on ETH supply — a narrative that helped fuel the token’s outperformance on June 30.
For DeFi users who had endured months of exorbitant gas fees during the bull run — with single transactions sometimes costing hundreds of dollars — the promise of a more efficient fee market was a powerful catalyst for renewed optimism.
DeFi Tokens Lead the Recovery
The EIP-1559 momentum translated into tangible price action across the DeFi sector. Compound (COMP) surged 8.7% to $337.92,Balancer (BAL) gained 9.2% to $22.13, and Maker (MKR) rallied 11% to $2,677. Aave (AAVE) advanced 5.4% to $250.10, while Kyber Network (KNC) climbed 8.5%.
The recovery in DeFi governance tokens was particularly notable given the broader market’s struggles. Total DEX volume had plummeted 50% during June — from $143 billion to $68 billion — reflecting a sharp contraction in speculative activity. Yet the tokens themselves showed resilience, suggesting that developers and long-term DeFi participants remained committed to the ecosystem despite the drawdown.
Polygon Eclipses Ethereum and BSC in Daily Activity
Perhaps the most striking on-chain development of June was Polygon’s explosive growth. The Layer 2 scaling solution saw its daily transaction count surpass both Binance Smart Chain and Ethereum by several-fold, cementing its position as the go-to scaling infrastructure for DeFi applications.
Projects like Aave, SushiSwap, and Curve Finance all deployed on Polygon during the period, drawn by near-zero transaction fees and rapid confirmation times. The migration highlighted a growing recognition that Ethereum’s Layer 1 congestion was pushing users toward scalable alternatives — and Polygon was capturing the lion’s share of that demand.
Polygon’s MATIC token traded at $1.17 on June 30, reflecting modest daily gains but significantly higher than its levels earlier in the quarter.
The Bigger Picture: ETH’s Q2 Resilience
While June was painful — ETH fell 15% during the month — the second quarter as a whole told a more nuanced story. Ethereum finished Q2 up approximately 18%, even as Bitcoin recorded its worst quarter since 2012 with a 42% decline. The divergence underscored ETH’s evolving narrative from purely a smart contract platform to an asset with its own distinct value proposition.
From its May 12 all-time high of $4,380, ETH had pulled back 48% by June 30. Yet the on-chain fundamentals continued to strengthen: total value locked in DeFi remained substantial, NFT activity showed no signs of abating, and the upcoming EIP-1559 upgrade offered a structural catalyst for supply dynamics.
Notable gainers on June 30 extended beyond DeFi. Rarible (RARI) exploded 42%, Augur (REP) surged 28%, and The Sandbox (SAND) climbed 11% — signaling that the NFT and metaverse subsectors were also finding their footing after the brutal May-June correction.
Why This Matters
June 30, 2021 captured the emerging split between Bitcoin and Ethereum narratives. While Bitcoin grappled with the China mining ban and macro headwinds, Ethereum was building toward its most consequential protocol upgrade since the Beacon Chain launch. The successful EIP-1559 testnet deployment validated the technical roadmap and gave the market a reason to look past the short-term pain. Combined with Polygon’s explosive Layer 2 adoption and DeFi’s structural resilience, the day highlighted why many analysts viewed Ethereum’s ecosystem as the most dynamic force in crypto — even in the depths of a bear market.

MKR doing 11% while BTC bled 2.3% on the same day. DeFi tokens were telling a completely different story than the market expected from EIP-1559
the fee burn narrative was so strong people forgot miners would fight it. took months after London for the actual deflationary pressure to show up
eip-1559 on testnet june 24 was the signal. compound up 8.7%, aave 5.4%, maker 11%. defi knew the fee burn was coming and positioned accordingly
maker up 11% on eip-1559 testnet news. people forget how bullish the fee burn narrative was before it actually launched
people also forget how much the fee burn narrative pumped the eth supply shrinkage thesis. that was the main driver of the q2 outperformance imo
Mika the fee burn narrative was so strong people were literally buying ETH because the supply was going to shrink. eip-1559 was the original ultra-sound money pitch
compound up 8.7% in a single day was the real signal here. defi tokens front-running eip-1559 like they had the insider playbook
eth down 48% from the 4380 ath but still up 18% for q2. that kind of relative strength during a btc bloodbath was unprecedented
68b dex volume in june sounds rough but polygon was eating everyone’s lunch. the l2 rotation started right here
polygon eating everyone’s lunch at this point was the canary in the coal mine. L2s were always going to win
polygon eating dex market share in june 2021 was the first real signal that L2s would eventually win. everyone was too busy watching the eth fee burn to notice
MKR doing 11% on EIP-1559 testnet news while being the protocol that benefits least from fee burning. market was just looking for any excuse to bid in 2021
fee_burn_clock MKR pumping 11% on EIP-1559 news was ironic since MKR doesnt benefit from fee burning at all. market just wanted an excuse to bid defi blue chips
the 377 gwei peak transaction in the same week DEX volumes halved tells you everything. power users were still farming while retail got priced out completely
^DEX volume dropping to $68B was the real signal. retail was gone by mid-June and the bounce was just protocols recycling TVL between themselves
DEX volume halving to 68B while ETH outperformed BTC tells you the rally wasnt retail driven. it was protocols recycling liquidity between their own pools
maker up 11% on testnet news while BTC was dumping 2.3%. the eth/btc divergence that day was one of the clearest signals of the cycle
