dYdX is a decentralised trading protocol where users can permissionlessly trade perpetual futures on crypto-assets and other types of assets. The dYdX protocol is deployed as an application-specific Layer-1 blockchain built for trading called the dYdX Chain that leverages the Cosmos SDK and CometBFT. dYdX lets users trade perpetuals over more than 200 different assets with no intermediaries and with full self-custody over user funds. The DYDX token plays a central role as the staking and governance token of the dYdX Chain. The DYDX token can be staked (delegated) to dYdX Chain validators in order to secure the network, participate in protocol governance and earn staking rewards. For more information onthe dYdX protocol, the dYdX Chain and the DYDX token, please refer to the official technical documentation and the DYDX Whitepaper.

dYdX Chain Validators

• The dYdX Chain protocol also relies on the operations of several validators, each of them operating autonomously and independently from the others. dYdX Chain validators are key ecosystem contributors and governance participants.

(a) Launch supply totals

A total of 1,000,000,000 ethDYDX were minted and programmed to become accessible over five (5) years, starting on August 3rd, 2021, at 15:00:00 UTC. The DYDX token was originally launched on 3 August 2021 on the Ethereum blockchain. Since the launch of the dYdX Chain, the original token on the Ethereum blockchain has been rebranded to ethDYDX (and the new canonical version of the token for the dYdX Chain protocol is now named DYDX and circulating on the dYdX Chain).

(b) Recipient categories & use of funds

The initial five-year allocation of the total token supply was as follows:

• 50.00% (500,000,000) to the community, broken down as follows: 25.00% (250,000,000) to users who trade on the Layer 2 Perpetuals Protocol (dYdX v3), based on a combination of fees paid and open interest; 7.50% (75,000,000) to past users who complete certain trading milestones on the Layer 2 protocol (dYdX v3) via Retroactive Mining; 7.50% (75,000,000) to liquidity providers based on a formula rewarding a combination of uptime, two-sided depth, bid-ask spreads, and the number of markets supported; 5.00% (50,000,000) to a community treasury; 2.50% (25,000,000) to users staking USDC to a liquidity staking pool; 2.50% (25,000,000) to users staking DYDX (now ethDYDX) to a safety staking pool.
• 27.73% (277,295,070) to past investors of dYdX Trading Inc.
• 15.27% (152,704,930) to founders, employees, advisors, and consultants of dYdX Trading Inc or the dYdX Foundation.
• 7.00% (70,000,000) to future employees and consultants of dYdX Trading Inc or the dYdX Foundation. Although the community allocation was established as presented above, DYDX holders have full control over how the community allocation is used. There was no airdrop for the DYDX native token on the dYdX Chain. Since launch, there have been several changes to the token’s initial allocation effected transparently through dYdX governance.

(c) Initial price per token (if applicable)

The initial price for the ethDYDX token registered on CoinMarketCap was approximately USD11.7, on 15 September 2021. The live price of the current DYDX token can be tracked onCoinMarketCap here

(d) Ticker / market symbol

DYDX (dYdX Chain native token) and ethDYDX (Ethereum-based token, formerly DYDX).

(e) Total supply & supply regime

Total initial supply: 1,000,000,000. A maximum perpetual inflation rate of 2.00% per year would increase the supply of DYDX (now ethDYDX) beginning after five years, ensuring the community continues to have the resources to continue contributing to the Protocol. Such inflation has not been activated as at the date of this submission (April 2026).

(f) Initial vesting / release schedules

Total supply became accessible over five (5) years, starting on August 3rd, 2021, at 15:00:00 UTC. On 31 January 2023, the dYdX Foundation announced that dYdX Trading Inc., the dYdX Foundation, and certain parties to the Warrants to Purchase Tokens holding a number of ethDYDX tokens sufficient to amend the Warrants, signed an amendment whereby, among other things, the transfer restriction schedule applicable to ethDYDX Tokens issued in connection with the Warrants was extended, including by postponing the initial unlock date to 1 December 2023 for all investors that are a party to the Warrants. As a result of the amendment, the unlock schedule for locked ethDYDX and locked DYDX tokens is:

• 30% locked tokens unlocked on 1 December 2023;
• 40% locked tokens unlocked in equal monthly installments on the first day of each month from 1 January 2024 to 1 June 2024;
• 20% locked tokens unlocked in equal monthly installments on the first day of each month from 1 July 2024 to 1 June 2025;
• 10% locked tokens unlock in equal monthly installments on the first day of each month from 1 July 2025 to 1 June 2026 (UTC). All Warrant investors are subject to the transfer restriction schedule outlined above. All founders, current employees, advisors, consultants, and the vast majority of past employees of dYdX Trading Inc and the dYdX Foundation (approximately 99.5%) are also subject to the transfer restriction schedule outlined above.

(a) Post-TGE employee lock as % of circulation

For post-TGE Foundation employees and team members, token vesting is handled off-chain for tax and operational reasons. Vesting generally happens at the beginning of each calendar month. 7.00% (70,000,000 DYDX) of the total supply was originally reserved for future employees and consultants of dYdX Trading Inc. or the dYdX Foundation. Unvested tokens awarded to post-TGE dYdX Foundation employees and team members represent 0.199% of DYDX’s total supply as of 22 April 2026. This data relates to the dYdX Foundation only, and does not take into account tokens awarded to employees and team members in other dYdX ecosystem entities.

(b) Typical post-TGE vesting schedule

The standard vesting schedule for initial token grants issued in favour of dYdX Trading Inc. and dYdX Foundation employees and team members includes a one (1) year cliff, 25% vesting on the one (1) year cliff, and linear monthly vesting of the remaining 75% of the tokens issued under the grant during the three (3) years following the cliff. Occasionally, bonus token grants can be issued to existing employees and team members (i.e., not new hires) based on their performance, which may have different vesting schedules (including no cliff and a shorter full vesting period of 2 or 3 years).

(a) Existence

A breakdown of DYDX tokens not in circulation (i.e., excluded from the circulating supply) is provided below:

As of the date of submission of this filing (April 2026), there are no agreements in place with market makers relating to the DYDX token or the token’s liquidity whereby the market makers received DYDX tokens or other consideration from the dYdX Foundation or dYdX Trading Inc. Without prejudice to the foregoing, the dYdX Grants Trust, a dYdX subDAO (now dissolved and wound down), entered into a Liquidity Consultancy Agreement with Pulsar using the industry-standard loan-option model. The Liquidity Consultancy Agreement with Pulsar was assigned to dYdX Grants Ltd. prior to the dissolution of the dYdX Grants subDAO.

As of the date of submission of the source filing, and to the best of the dYdX Foundation’s knowledge, there are no agreements in place with centralised or decentralised exchanges relating to the DYDX token or the token’s liquidity whereby the exchanges received DYDX tokens or other consideration from the dYdX Foundation or dYdX Trading Inc.

(a) Token repurchases or secondary-market accumulations (if any)

DYDX Buyback Program: 75% of all Net Protocol Revenue is currently being automatically allocated to the dYdX Treasury subDAO and used to buy back DYDX tokens in the open market and stake them to dYdX Chain validators to contribute to the security of the network. Source of funds: Net Protocol Revenue [Trading Fees + Transaction Fees] − [Affiliate Payments + Maker Rebates]. Treatment: treasury retention (staked to dYdX Chain validators). Controller/approvals: automatic allocation, controlled through dYdX Chain on-chain governance. The distribution of protocol revenue, including recipients and percentage allocations, can be controlled and determined through dYdX Chain on-chain governance and may change from time to time.

(b) Protocol-owned liquidity (POL)

MegaVault: 5% of all Net Protocol Revenue is automatically allocated to the MegaVault, the dYdX Chain protocol’s automated liquidity engine which has been set to “close only” mode as of the date of this submission (April 2026).. Controller: automatic allocation, controlled through dYdX Chain on-chain governance. The MegaVault’s historic and current balances and holdings /transactions are fully transparent on-chain and can be inspected here. Users can lock USDC into the MegaVault for 30 days to list a market instantaneously on dYdX Chain.

(c) Liquidity deals / purchased TVL

Liquidity Consultancy Agreement between the dYdX Grants Trust (subDAO) and Pulsar: loan of 250,000 DYDX tokens for a duration of 12 months, with an option for Pulsar to acquire the DYDX tokens at term expiration should DYDX hit the different strike prices set out in the agreement (priced at considerable premiums to the then-applicable market price). Pulsar provides liquidity for the DYDX token on Binance and OKX, for the DYDX/USDT trading pair specifically. This LCA has been assumed by dYdX Grants Ltd. following the dissolution of the dYdX Grants subDAO. The agreement will expire on 14 May 2026.

(d) Token-secured loans/lines (incl. against unissued tokens)

As at the date of this filing (April 2026), and to the best of the dYdX Foundation’s knowledge, there are no active token-secured loans, credit lines or positions collateralised by DYDX tokens entered into by the dYdX Foundation or dYdX Trading Inc.

Prior to the establishment of the dYdX Foundation, dYdX Trading Inc. engaged in four rounds of financing, which included sales of preferred stock and warrants to purchase future tokens. Each warrant allowed the investor to purchase a pro rata portion of DYDX tokens based on the investor’s equity ownership in dYdX Trading Inc. The details of dYdX Trading’s Seed, Series A, Series B and Series C rounds were publicly announced. The dYdX Foundation also distributed DYDX tokens to founders, employees, consultants and advisors of dYdX Trading Inc. and the dYdX Foundation pursuant to restricted token purchase agreements and restricted token unit agreements, which contain a vesting schedule and a lockup in line with the lockup on DYDX Tokens purchased by investors. The dYdX Foundation raised funds from the dYdX DAO’s Community Treasury in January 2024 and again from the dYdX Chain’s Insurance Fund in April 2026; both fundraisings were openly discussed in the community forum and approved by the dYdX DAO through on-chain governance votes. The dYdX Foundation received 10,915,674 DYDX tokens from the dYdX Chain Community Treasury pursuant to the January 2024 community fundraise, and 2,500,000 USDC tokens from the dYdX Chain Insurance Fund pursuant to the April 2026 community fundraise. Without prejudice to the foregoing, and to the best of the dYdX Foundation’s knowledge as of the date of this filing, there have been no material OTC sales of DYDX tokens by dYdX ecosystem entities to external investors or discounted sales of DYDX tokens to market makers.

(a) Entity existence

The dYdX Foundation, dYdX Trading Inc. (Lab/DevCo), and the dYdX DAO all exist.

(b) Material sources of funding or economic inflows

dYdX DAO / protocol revenue: dYdX Chain revenue consists of trading and transaction fees paid by users of the protocol, which are predominantly denominated in USDC. Prior to distribution according to the revenue share allocations controlled by dYdX Chain governance, a portion of gross protocol fees are automatically sent by the protocol to (A) dYdX Affiliates, who automatically receive a portion of their referred users’ taker fees; and (B) dYdX users that qualify for Maker Rebates. Gross Protocol Revenue = Trading Fees + Transaction Fees. Net Protocol Revenue = [Trading Fees + Transaction Fees] − [Affiliate Payments + Maker Rebates]. Net Protocol Revenue is distributed as follows: 15% to DYDX stakers (delegators) as staking rewards; 5% to the MegaVault; 75% to the dYdX Treasury subDAO for the DYDX Buyback Program; 5% to the dYdX Treasury subDAO for DAO OPEX, financial planning and financial sustainability activities. dYdX Foundation: Received 10,915,674 DYDX tokens from the dYdX Chain Community Treasury in January 2024 following a successful community governance proposal. More recently, received 2,500,000 USDC from the dYdX Chain Insurance Fund following a successful community governance proposal. The Foundation publicly discloses information on its financial position periodically as part of the dYdX ecosystem annual and semi-annual reports. dYdX Trading Inc.: Raised capital through Seed, Series A, Series B and Series C rounds (sale of preferred stock plus Warrants to Purchase Tokens). dYdX Trading Inc and its equityholders do not have any direct value-accrual rights with regard to the dYdX Chain protocol’s revenue.

(c) Operational use of resources

The dYdX Foundation uses its resources towards its main responsibilities in a professional manner, including: DAO and governance support, ecosystem growth, grants, marketing and educational efforts, regulatory research and planning, IP and brand protection, and stakeholder relationships. dYdX Trading Inc. allocates most of its resources towards the development of the dYdX open-source software and the development of other blockchain software, including through the retention of top-tier engineering talent. The dYdX Treasury subDAO uses its 5% net protocol revenue allocation for DAO OPEX, financial planning and financial sustainability activities within the dYdX ecosystem, and its 75% net protocol revenue allocation for the DYDX Buyback Program. The MegaVault uses its 5% net protocol revenue allocation as the dYdX Chain protocol’s automated liquidity engine.

(d) Current economic rights, if any

All dYdX Chain protocol revenue accrues to dYdX traders, dYdX Affiliates, dYdX Chain validators and stakers, the MegaVault, and the dYdX Treasury subDAO, per the governance-controlled revenue share described above. dYdX Trading Inc and its equityholders have no direct value-accrual rights to protocol revenue and future protocol revenue cannot be distributed to them (including through dividends or share repurchases). The dYdX Foundation is a memberless not-for-profit with no equityholders.

The only significant example of a prior exploit or security incident that affected dYdX Chain protocol funds is the 10 October 2025 network outage, which resulted in $462,000 in reimbursements from the dYdX Chain Insurance Fund to affected users. The specific details of such chain outage and its implications are described below:

(a) Date & Component Affected

2025-10-10; temporary outage caused by a misordered process in collateral pool transfers during liquidations in isolated markets.

(b) Exploit Vector Summary

during a period of extreme market volatility, asset prices dropped sharply across most markets. While the dYdX v4 exchange software is designed to handle large-scale liquidations and deleveraging events, the unusual conditions triggered a rare edge case. In this scenario, the entire open interest of an isolated market was included in a single liquidation trade. This triggered logic to return remaining collateral from the isolated market's pool to the primary collateral pool, with the isolated market’s insurance fund or auto-deleveraging typically covering any shortfall between the liquidation price and the user's bankruptcy price. Due to an incorrect order of operations in this process, the collateral pool transfer communicated a negative

• balance despite the isolated market’s insurance fund having ample capital to cover the deficit. Because the insurance fund could cover the shortfall, auto-deleveraging did not trigger to net out the positions in the isolated market either. This collateral pool transfer failure triggered a protocol-level failsafe mechanism which is intended to force a chain halt to ensure that no additional funds can be minted within the system where there is a net deficit in the collateral pool (though in this instance there was no actual protocol solvency issue). As a result, the chain halted to maintain state integrity. While the chain was halted, all network activity, including oracle price updates and liquidations, was paused. When the chain restarted, some validators had not restarted the oracle sidecar service which provides price updates for markets, resulting in some transactions executing at uneconomic prices before normal oracle functionality was restored.

(c) Quantified Impact

approximately $462,000 in reimbursements were issued from the dYdX Chain’s Insurance Fund to users adversely impacted by stale oracle prices.

(d) Remediation / Response Taken

In addition to the reimbursement, dYdX Trading Inc.’s engineering team developed a patch to address the edge case that was the root cause of the chain halt and has worked with the dYdX Operations subDAO, validators and other stakeholders to strengthen incident response procedures.

(e) Current Status

resolved.
