Wood founded Parity Technologies and co-founded the Web3 Foundation in 2016–2017 with the goal of building an interoperable, multi-chain web. The Web3 Foundation conducted a public token sale for DOT in October 2017, raising approximately $140 million by selling 50% of an initial 10 million DOT supply. The project mainnet launched in May 2020. Polkadot operates as a Layer 0 network: independent blockchains (called parachains) connect to a central Relay Chain that provides shared security and cross-chain messaging. The technical work is split between the Web3 Foundation (grants and research) and Parity Technologies (client development).","heading":"Background and Founding","severity":"low","sources":[{"credibility":2,"name":"Gavin Wood - Wikipedia","type":"other","url":"https://en.wikipedia.org/wiki/Gavin_Wood"},{"credibility":2,"name":"History of Polkadot: Connecting the DOTs - DailyCoin","type":"news_article","url":"https://dailycoin.com/history-of-polkadot-connecting-dots/"},{"credibility":2,"name":"Polkadot (DOT) ICO Overview - ICO Drops","type":"other","url":"https://icodrops.com/polkadot/"}]},{"content":"Polkadot's 2017 ICO raised approximately $145 million. Within two weeks of the sale closing, Parity Technologies suffered a critical smart contract vulnerability in November 2017. A user accidentally triggered a bug in Parity's multi-signature wallet library, permanently freezing an estimated 513,774 ETH across 587 wallets. Polkadot's ICO funds represented approximately $98 million of the frozen assets, accounting for roughly 60-67% of the total. A separate July 2017 Parity hack had earlier resulted in approximately $30 million in ETH stolen from other wallets. Parity's CEO stated publicly that frozen funds were not 'lost,' and the Web3 Foundation ultimately proceeded with Polkadot development using remaining liquid capital. A proposed Ethereum Improvement Proposal (EIP-999) to recover the frozen funds was controversial and never adopted. The ICO funds frozen in the Parity wallet have never been recovered.","heading":"2017 ICO and Parity Wallet Freeze","severity":"medium","sources":[{"credibility":1,"name":"ICO Funds Among Millions Frozen In Parity Wallets - CoinDesk","type":"news_article","url":"https://www.coindesk.com/markets/2017/11/09/ico-funds-among-millions-frozen-in-parity-wallets"},{"credibility":2,"name":"EIP-999: Why A Vote To Release Parity Locked Funds Evoked So Much Controversy - CoinTelegraph","type":"news_article","url":"https://cointelegraph.com/news/eip-999-why-a-vote-to-release-parity-locked-funds-evoked-so-much-controversy"},{"credibility":1,"name":"Parity CEO confident $150M frozen Ethereum isn't lost - TechCrunch","type":"news_article","url":"https://techcrunch.com/2017/12/05/parity-ceo-says-shes-confident-that-its-280m-in-frozen-ethereum-isnt-lost-forever"},{"credibility":2,"name":"The Story Of Polkadot Starts With The 2017 ICO - CryptoPotato","type":"news_article","url":"https://cryptopotato.com/the-story-of-polkadot-starts-with-the-2017-ico-2000-roi-for-early-investors/"}]},{"content":"On March 17, 2026, the U.S. Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) issued joint interpretive guidance classifying Polkadot's DOT token as a 'digital commodity' alongside 15 other major cryptocurrencies. The classification places DOT under CFTC jurisdiction rather than SEC securities law, reducing disclosure burdens and easing access for institutional investors. This follows years of ambiguity about whether DOT constituted a security; the Web3 Foundation had previously argued that DOT had 'morphed' from a security into software and thus fell outside SEC jurisdiction. The joint guidance resolves this question in Polkadot's favor at the federal level as of March 2026, though the guidance does not retroactively address the DOT ICO of 2017.","heading":"Regulatory Classification: Digital Commodity (U.S.)","severity":"low","sources":[{"credibility":1,"name":"SEC/CFTC Interpretation Names Polkadot (DOT) As A Digital Commodity - Mondaq","type":"regulatory","url":"https://www.mondaq.com/unitedstates/fintech/1762852/seccftc-interpretation-names-polkadot-dot-as-a-digital-commodity-key-takeaways"},{"credibility":2,"name":"SEC's Token Taxonomy Is Official: 16 Crypto Assets Are Now Digital Commodities - Disruption Banking","type":"news_article","url":"https://www.disruptionbanking.com/2026/03/19/secs-token-taxonomy-is-official-16-crypto-assets-are-now-digital-commodities/"},{"credibility":2,"name":"SEC CFTC Crypto Commodity List 2026: All 16 Digital Assets Named - CoinPedia","type":"news_article","url":"https://coinpedia.org/news/sec-cftc-crypto-commodity-list-2026-all-16-digital-assets-named-and-what-it-means/"}]},{"content":"On March 6, 2026, 21Shares launched the first U.S. spot Polkadot ETF on Nasdaq under the ticker TDOT.

By forging a malicious state proof and bypassing the Merkle tree verifier, the attacker gained unauthorized minter control over the DOT token contract on Ethereum and minted approximately 1 billion fraudulent DOT tokens. The attacker rapidly dumped these tokens into low-liquidity Ethereum pools, extracting approximately $237,000–$250,000 in actual value before the exploit was identified. Security firm CertiK flagged the exploit on-chain. Hyperbridge was paused during the investigation. The Polkadot native chain and native DOT were not affected. The exploit was contained to the Ethereum-side bridge contract. The limited financial damage was a function of shallow liquidity in the Ethereum DOT pools, not of any successful defensive action. Security researchers noted the vulnerability — insufficient verification of state proofs in Hyperbridge's ISMP pipeline — and warned that similar flaws in bridges with deeper liquidity could result in substantially larger losses.","heading":"Hyperbridge Ethereum Exploit (April 2026)","severity":"high","sources":[{"credibility":2,"name":"Attacker Mints $1 Billion in Fake Polkadot Tokens on Ethereum but Steals Only $250,000 - Unchained","type":"news_article","url":"https://unchainedcrypto.com/attacker-mints-1-billion-in-fake-polkadot-tokens-on-ethereum-but-steals-only-250000-unchained/"},{"credibility":2,"name":"Polkadot Hack: Attacker Exploits Ethereum Contract and Mints 1B DOT Tokens - The Crypto Times","type":"news_article","url":"https://www.cryptotimes.io/2026/04/13/polkadot-hack-attacker-exploits-ethereum-contract-and-mints-1b-dot-tokens/"},{"credibility":1,"name":"Attacker mints $1 billion Polkadot tokens on Ethereum, ends up stealing just $250,000 - CoinDesk","type":"news_article","url":"https://www.coindesk.com/tech/2026/04/13/attacker-mints-usd1-billion-polkadot-tokens-on-ethereum-ends-up-stealing-just-usd250-000"},{"credibility":2,"name":"DOT Exploit Shock: 1 Billion Tokens Minted, Dumped in Minutes - Yahoo Finance","type":"news_article","url":"https://finance.yahoo.com/markets/crypto/articles/dot-exploit-shock-1-billion-070934992.html"},{"credibility":2,"name":"Polkadot Confirms Exploit on Hyperbridge's Ethereum Gateway Contract - The Defiant","type":"news_article","url":"https://thedefiant.io/news/hacks/polkadot-confirms-exploit-on-hyperbridge-s-ethereum-gateway-contract-sjb0ql"}]},{"content":"Polkadot operates an on-chain treasury managed through its OpenGov decentralized governance system. In the first half of 2024, the treasury spent approximately $87 million, compared to a combined $46 million in all of 2022 and 2023 combined. Of the H1 2024 expenditure, approximately $37 million was allocated to marketing, advertising, and events — a figure that prompted significant community criticism. Polkadot's Head Ecosystem Ambassador publicly estimated in 2024 that the treasury's then-approximately $245 million balance would be exhausted within two years at current burn rates. In Q4 2025, the treasury recorded a quarterly report flagging negative net flows of nearly 101,000 DOT in a single month. A governance proposal to reduce inflation was rejected by 57% of participating voters, further complicating sustainability efforts. In May 2026, Polkassembly — the primary governance interface for Polkadot and Kusama, which tracked over 1,700 referenda and served more than 250,000 participants — shut down after operating for over five years. Co-founder Jaskirat Singh cited a pattern of ecosystem leadership failures, DAO overspending, and the failure of the Polkadot treasury to pay Polkassembly for its services for approximately eight months prior to closure. These are factual governance events; the characterization of their severity is disputed between critics and Polkadot Foundation representatives.","heading":"Treasury Spending Controversy and Governance Concerns","severity":"high","sources":[{"credibility":2,"name":"Polkadot spent $87 million in half a year - BlockBeats","type":"news_article","url":"https://m.theblockbeats.info/en/news/54059"},{"credibility":2,"name":"Polkadot defends $37m splurge on influencers and private jet logos - DL News","type":"news_article","url":"https://www.dlnews.com/articles/defi/polkadot-defends-millions-spent-on-marketing-as-budget-booms/"},{"credibility":2,"name":"Polkadot's Head Ecosystem Ambassador Expects Chain's $245 Million Treasury to Run Dry in 2 Years - Unchained","type":"news_article","url":"https://unchainedcrypto.com/polkadot-expects-245-million-multi-chain-treasury-to-run-dry-in-2-years/"},{"credibility":2,"name":"2025-Q4 Polkadot Treasury Report - Polkadot Forum","type":"official","url":"https://forum.polkadot.network/t/2025-q4-polkadot-treasury-report/16847"},{"credibility":2,"name":"Polkassembly Governance Infrastructure for Polkadot (2020-2026)","type":"official","url":"https://polkassembly.io/"},{"credibility":2,"name":"'Polkadot Is Kind of Done.' - The Defiant","type":"news_article","url":"https://thedefiant.io/news/blockchains/polkadot-ecosystem-update-may-2026"}]},{"content":"Moonbeam, widely described as a flagship Polkadot parachain offering Ethereum-compatible smart contracts, announced in 2026 that it would fully migrate its GLMR token off Polkadot to Coinbase's Base Layer 2, relaunching as an AI-agent network.

Moonbeam's TVL across parachains declined from approximately $275.73 million in January 2022 to approximately $1.34 million by July 2026. Coverage from The Defiant and Crypto News Net characterized the departure as one of the more significant exits from the Polkadot ecosystem. GLMR tokens migrated on a 1:1 basis to native ERC-20 tokens on Base. The exit contributed to bearish market sentiment around DOT, with the token dropping approximately 3.6% in the days surrounding the announcement.

The reform ends Polkadot's previously open-ended inflationary model and transitions to a disinflationary schedule, with issuance decreasing every two years. Approximately 1.6 billion DOT are in circulation as of mid-2026, representing about 76% of the eventual hard cap. The changes reduce current inflation from approximately 7.5% to approximately 3.3% annually, with projections below 1% by the mid-2030s. The hard cap was modeled after Bitcoin's 21 million limit, scaled by a factor of 100.

Q1 2026 targets included a mainnet governance referendum for the JAM upgrade. The official public JAM testnet and CoreChain Phase 1 deployment were planned for 2026. Q3 and Q4 2026 are designated as critical testing and early deployment phases. JAM's CoreVM module demonstrated the ability to stream audio and video directly into a browser in a trustless manner, which proponents cite as a demonstration of its compute capabilities.
