Institutional-Grade Security for Advanced Onchain Trading

Institutional-Grade Security for Advanced Onchain Trading

Security Challenges in DeFi

In digital assets, the stakes for security are higher than ever. As institutional investors such as liquid fund managers, OTC desks, and professional traders enter the space, they demand airtight protection for client assets, proprietary strategies, and operational integrity.

Today, institutions moving onchain must navigate a fragmented landscape of trading solutions where security is often bolted on as an afterthought. Smart contract hacks, lack of operational controls, and exposure to predatory actors have kept many funds, DAOs, and institutions wary of fully embracing decentralized trading infrastructure.

At Definitive, security isn’t an add-on — it’s our foundation. Our experienced team has built and scaled institutional-grade trading infrastructure to billions in trading volume at Coinbase and other crypto and TradFi firms prior to Definitive. This case study breaks down the multi-pronged security framework underpinning Definitive’s onchain trading platform, highlighting how we protect client assets, defend against onchain attacks, and offer operational safeguards unmatched by other DeFi trading solutions.

Non-Custodial by Default, No New Private Keys

Definitive’s infrastructure enables full client control of assets without the additional complexity of managing new wallets and keys. There’s no need to generate new wallets (and private keys) when onboarding to Definitive. Clients simply connect their existing self-custody wallet of choice; Definitive supports 250+ wallets, including Fireblocks, Fordefi, Gnosis Safe, and EOAs.

• Every client trades from bespoke trading vaults — unique smart accounts deployed exclusively for their use, ensuring complete segregation of assets from Definitive itself as well as other clients.
• The client’s wallet is whitelisted as the owner of these smart account-based trading vaults. Only wallets explicitly whitelisted by the client are authorized to initiate trades or withdrawals.
• If Definitive’s infrastructure were ever compromised, clients still maintain full control over their assets and can withdraw directly onchain via Etherscan or similar block explorers.

By design, Definitive eliminates the additional burden of managing yet another set of private keys as well as asset commingling, major vulnerabilities found in other trading solutions.

Platform Architecture: Security by Design

At Definitive, security is not just a policy — it’s enabled in our code.

• Our smart contracts feature pre-defined permissioning layers, supporting granular roles including Admin, Trader and View-Only.
• Every swap transaction is simulated by our smart order router prior to execution. This allows Definitive to detect malicious or compromised pools or DEXs before submitting the transaction to the blockchain and protects clients from exposure.
• Best-in-class internal security protocols require any changes to any part of the Definitive codebase to be approved by another member of the Definitive engineering team, making compromising Definitive systems difficult.
• We’ve completed multiple security audits conducted by leading security firms Zellic and OtterSec.
• To date, over 3 million trades and $2.4B+ in volume have been executed with zero smart contract hacks.

All of Definitive’s prior audit reports are available to review here. Importantly, our architecture avoids common pitfalls that have led to past breaches on other platforms by strictly controlling onchain permissions, ensuring asset segregation, performing swap simulations, and more.

Role-Based Access & Sub-Account Controls

Institutional teams require operational flexibility without sacrificing security. Definitive’s role-based system makes it easy to manage permissions.

Role-based access control includes:

• View-Only: Read-only access for auditors, fund admins, and back-office teams.
• Trader: Authorized to place trades but restricted from making withdrawals.
• Admin: Full permissions, including trading, withdrawals and asset transfers.

For even greater control, Definitive supports Sub-Accounts, allowing institutions to:

• Assign dedicated wallets per trader per sub-account.
• Ringfence risk by setting capital limits per sub-account.
• Separate strategies and manage client SMA (Separately Managed Account) structures compliantly.

These features address internal risk vectors that other DeFi trading platforms simply don’t cover.

Disaster Recovery: Always in Your Control

Even in a worst-case scenario where Definitive’s systems go offline, clients remain in full control.

• Client-owned smart account vaults ensure that Definitive cannot access, move, or control client funds.
• Withdrawals can be executed directly onchain, bypassing any need for Definitive’s front-end or back-end.

This robust fallback distinguishes Definitive from trading platforms that rely on front-end availability for access to assets.

Institutional Validation: Proven at Scale

Definitive’s security architecture isn’t theoretical — it’s been battle-tested at scale:

All from an experienced team that built institutional trading infrastructure at Tagomi and Coinbase, scaling to billions in trading volume prior to Definitive. Definitive was built to meet the standards demanded by serious capital — and our track record speaks for itself.
