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.

EIP-1559 burning base fees is the most bullish ETH narrative ever. supply goes down while usage goes up
MKR up 11% and BAL up 9.2% in a single day. DeFi tokens were so correlated back then
tim beiko confirming the first 1559 testnet block on june 24 was the catalyst. the market rallied on that news for a week straight
ETH still down 48% from the $4,380 ATH but outperforming BTC by 7.5% on the day. rotation was real
DEX volumes halved to $68B but polygon was surging. that was the beginning of the L2 meta
