It's been a long time coming... But it's finally time Part of evolving as a business is recognising where your focus should be while remembering who your users are. The reality is that we spent an incredible amount of time purpose-building a network that is specifically designed to cater to HFT and everything that it encompasses. Execution needed to be faster and limitations to throughput hindered our ability to run real time risk checks as we think about scaling to 100,000 to 1,000,000 users and beyond. For those who have been following along, its no secret that there has been friction between how we execute and what the preference is from Solana leadership. I understand and respect their stance, however to continue to frame BULK a solana dex would be reductive to the actual offering, so we’re officially putting this on the record. The stronger case is that multichain access expands BULK’s distribution and usable capital while bringing more activity into the same market. Distribution follows where users hold their money. As more people enter crypto through neobanks, wallets and payment applications, their first chain may simply be whichever network their provider uses. Their choice of trading venue will depend on execution quality, liquidity and convenience. Requiring those users to move to a particular chain before they can trade creates an acquisition barrier: another transaction, another fee, another interface and another opportunity to abandon onboarding. It also asks wallets and neobanks to move customers away from their existing infrastructure to integrate BULK. Multichain access lets BULK meet that distribution where it already exists. A wallet or neobank could offer its customers BULK markets through the rails they already use. The lesson from multicurrency products like Wise is that a single financial relationship can span across several underlying currencies and payment systems. We expect users to increasingly demand the same convenience across chains. A unified clearing layer can make capital more productive and markets more liquid. The strongest clearinghouse analogy is capital efficiency. Traditional clearing infrastructure brings eligible collateral and positions into a common risk framework, allowing qualifying exposures to offset and reducing the capital required to support them. This today belongs to CME Group. For BULK, the opportunity is to connect capital held across supported chains to a common margin system and shared order book. A trader’s access to liquidity should not depend on which chain funded their account. A market maker should be able to serve that combined demand through the same BULK markets. This creates an economic advantage: more sources of capital and order flow can support deeper books; deeper books can improve execution; better execution can attract more traders and integrations. That advantage depends on keeping liquidity concentrated. Multichain access should bring users into the same markets, with eligible collateral recognized under a consistent risk framework. It should also let users withdraw available capital through supported destination chains, making BULK useful within their wider financial activity. BULK’s specialised execution layer gives it a natural role connecting these rails. BULK is a purpose-built trading L1 rolled into an order book, matching engine and risk engine. Its value comes from how efficiently it executes trades and manages risk. That specialization gives it a reason to serve capital from multiple ecosystems. Today, collateral lives on Solana, and BULK’s ledger tracks the corresponding balances, positions and margin. Extending that model to supported networks such as Arc, Tempo, Arbitrum and HyperEVM would allow more funding and withdrawal routes to connect to the same execution system. The architectural principle is to handle each chain’s confirmation and settlement requirements at the funding boundary. Once collateral is securely recognised, trading should run through BULK’s own execution and risk process. This allows BULK to preserve its performance while broadening access. The intended experience is straightforward: fund from a supported chain, trade against BULK’s shared liquidity, and withdraw available balances to a supported destination. A user could enter from Solana and exit on HyperEVM, with BULK coordinating the accounting, settlement and destination liquidity required. For wallets and neobanks, that would make BULK an exchange and clearing integration they can use across their supported networks. Each additional rail would expand access to the same venue, and strengthen the market already serving everyone else.
