2025 · 19 recorded events
What happened in crypto in 2025? All 19 events on this timeline, including Ethereum Pectra Upgrade Activates — each dated, categorised and sourced.
2025 has more entries than any other year in this archive, split between policy and stress. The US reversed its crypto policy by executive order in January, established a Strategic Bitcoin Reserve in March, and enacted the GENIUS Act — the first federal stablecoin framework — in July. Bitcoin set records in May and again in October, peaking near $126,000. Four days after that peak, the largest liquidation cascade on record wiped out more than $19 billion in 24 hours. Security ran in the other direction: the $1.46 billion Bybit theft in February is still the largest in crypto history. Ethereum shipped Pectra in May and Fusaka in December.
By category, 2025 breaks down into four regulatory and policy decisions, three technical milestones, three market milestones, three crashes and crises, three hacks and exploits and three adoption and institutional entries. Five of those entries carry a disclosed dollar figure: $1.81 billion stolen across three entries, $93 million customer shortfall and $19 billion liquidated. These are different kinds of number and are not added together.

A Solana token branded to the incoming US president reached a multi-billion-dollar market capitalization within 48 hours, with 80% of supply held by affiliated entities. It drained liquidity from the rest of the memecoin market and became the sharpest conflict-of-interest question in US crypto policy.
Executive Order 14178 revoked the previous administration's framework, banned work on a retail central bank digital currency, protected self-custody and created a working group to propose a digital asset stockpile. It also directed agencies to end enforcement actions lacking statutory basis.
Attackers compromised a Safe{Wallet} developer machine and injected code that spoofed the signing interface, tricking Bybit signers into approving a transfer of roughly 401,000 ETH from a cold wallet. The FBI attributed it to North Korea's Lazarus Group; Bybit kept withdrawals open and replaced the reserves.
Executive Order 14233 created a Strategic Bitcoin Reserve capitalized with forfeited government BTC that may never be sold, plus a separate Digital Asset Stockpile for other seized tokens. Officials were authorized to explore budget-neutral acquisition strategies.
A sweeping US import-tariff package sent global markets into a risk-off spiral, and bitcoin fell toward $75,000 within a week. The episode confirmed that crypto now trades as a high-beta macro asset rather than an uncorrelated hedge, ahead of a partial policy rollback.
Activated at epoch 364,032, Pectra bundled eleven EIPs — the network's largest fork by EIP count. EIP-7702 gave ordinary accounts smart-contract capabilities, the validator stake ceiling rose to 2,048 ETH, and blob throughput was increased for layer 2s.
Bitcoin reached roughly $111,980, a new record set against a backdrop of sovereign reserve policy, steady ETF demand and corporate treasury buying. Open interest in derivatives hit about $74 billion the same day, a sign that leverage was rebuilding alongside spot demand.
A faulty overflow guard in a fixed-point math library let an attacker mint enormous liquidity credit from a minimal deposit and drain pools across the Sui ecosystem. Validators froze about $162 million still on-chain, and recovery was approved by an on-chain community vote.
The USDC issuer priced its IPO at $31 and raised about $1.05 billion, with the stock more than doubling on day one. It gave public markets their first direct exposure to stablecoin economics — a business that earns interest on reserves rather than trading fees.
xStocks brought more than 60 fully collateralized US shares — including Apple, Nvidia and Tesla — on-chain as Solana tokens, each a 1:1 claim on stock held by a regulated custodian. On-chain value grew from roughly $35 million to over $100 million within two weeks.
During "Crypto Week" the House approved a market-structure bill splitting oversight between the SEC and CFTC, with digital commodities going to the CFTC. It then stalled in the Senate, where committee approval did not arrive until May 2026.
Public Law 119-27 established the first US federal regime for payment stablecoins: 100% liquid reserves, monthly disclosures, Bank Secrecy Act obligations and priority for holders in insolvency. Agencies missed the July 2026 rulemaking deadline, pushing effectiveness toward January 2027.
The lending protocol crossed $50 billion in total value locked, a scale comparable to a mid-sized bank's balance sheet. It marked the point at which core DeFi money markets became systemically relevant rather than experimental.
Bitcoin set an all-time high near $126,000 after $3.5 billion of September ETF inflows and expectations of US rate cuts. It remains the highest price on record and, four days later, the starting point of the deepest drawdown of the cycle.
A surprise announcement of 100% tariffs on Chinese imports hit a market carrying $217 billion of perpetual open interest. Over $19 billion in leveraged positions were liquidated in 24 hours and 1.6 million accounts were wiped out, with bitcoin falling from $122,500 to below $105,000.
Spot SOL funds listed on the NYSE and Nasdaq, several of them passing staking rewards through to holders — a structure US regulators had refused for ether a year earlier. First-day inflows reached $69.5 million, extending regulated access beyond bitcoin and ether.
An attacker batched dozens of micro-swaps to compound a rounding error in Balancer's scaling function, suppressing pool token prices across six chains in under 30 minutes. Because many protocols composed on top of these pools, the damage spread well beyond Balancer itself.
Stream Finance disclosed a $93 million loss tied to an external manager and halted redemptions, removing the arbitrage that held its yield-bearing stablecoin at a dollar. xUSD fell as much as 57% and dragged down other synthetic dollars that had used it as collateral.
Activated at epoch 411,392, Fusaka introduced peer data availability sampling so nodes verify only a fraction of each blob, plus config-only BPO forks that raise blob limits in stages. Average gas fees fell to their lowest levels in years.
