Definitive for Institutions: Institutional-Grade Onchain Trading

Definitive is an onchain trading terminal purpose-built for institutions, DeFi hedge funds, family offices, and OTC desks. It connects to your existing custody infrastructure — Fireblocks, Fordefi, Safe, Squads, or any EOA — and gives your team advanced order execution, post-trade reporting, and privacy controls across 9 chains, all without touching gas.

Why Institutions Are Moving Onchain

The shift from CEX to onchain execution is no longer theoretical. Liquidity is deeper, settlement is final, and self-custody eliminates counterparty risk. But most onchain tools were built for retail — they lack the order sophistication, custody integrations, and reporting that institutional workflows demand.

That gap is exactly what Definitive was built to close.

CEX risk is real. FTX demonstrated what happens when institutional capital sits on a centralized exchange. Self-custody onchain execution removes the custodial risk entirely — assets stay in your wallet, under your keys, until the moment of settlement.

Onchain liquidity has matured. With smart order routing across 100+ DEXs and 15+ offchain PMMs simultaneously, Definitive achieves execution quality that rivals — and often beats — centralized venues for large-cap and mid-cap tokens.

The regulatory direction is clear. Institutions that build onchain infrastructure now are positioning ahead of the compliance curve, not behind it. Post-trade reporting, auditable execution records, and transparent fee structures are built into Definitive from day one.

Execution infrastructure matters. Slippage, MEV exposure, and fragmented liquidity are execution risks. Definitive's smart order routing and TWAP execution exist specifically to manage these risks at institutional scale.

What Definitive Offers Institutions

Definitive is not an aggregator. It is a professional-grade institutional DeFi trading terminal that combines order management, execution, routing, and reporting in a single interface.

Advanced order types — all onchain. TWAP, Limit, Stop, and Market orders are available across all supported chains. These are not off-chain simulations — they execute onchain with full settlement finality.

Smart order routing. Every order is routed across 100+ DEXs and 15+ offchain PMMs to minimize slippage and maximize fill quality. Routing is automatic and continuous — your desk does not need to manage it manually.

Gasless execution. Definitive sponsors gas on every supported chain. Your team never needs to hold native gas tokens, manage gas wallets, or build gas top-up workflows into your operations. This is especially significant for multi-chain operations managing positions across Base, Arbitrum, Ethereum, Optimism, Polygon, Avalanche, BNB, HyperEVM, and Solana simultaneously.

Fee tiers for volume. Institutional desks trading at scale benefit from Definitive's tiered fee structure. The base rate is 85 bps (T5). Volume tiers and staked EDGE reduce fees progressively down to 25 bps at T1. Major assets and stablecoins on Ethereum, Base, Solana, and Arbitrum trade free of charge.

Custody and Access Control

The most important question for any institution evaluating onchain execution infrastructure is: where do assets sit, and who controls them?

With Definitive, assets never leave your custody. The terminal connects directly to your existing custody setup — no bridging, no intermediary wallets, no counterparty holding your funds.

Fireblocks integration. Institutional desks using Fireblocks can connect directly. Policy rules, co-signing requirements, and approval workflows configured in Fireblocks remain fully intact. Definitive executes through your existing Fireblocks setup without requiring any changes to your custody policy.

Fordefi integration. Fordefi users have native support. The MPC custody model is preserved end-to-end — Definitive initiates transactions, Fordefi signs and broadcasts them under your existing policy engine.

Safe and Squads multisig. For teams using Safe (EVM) or Squads (Solana), Definitive integrates natively. Multisig approval requirements, threshold configurations, and role permissions remain exactly as your team has configured them. Definitive presents transactions to the multisig queue — signers approve in their normal workflow.

Any EOA. Teams using hardware wallets or software EOAs connect directly without any additional configuration.

Performer Addresses. For institutions requiring execution privacy, Definitive's Performer Address system routes orders through proxy addresses. Your primary wallet address is not visible onchain during execution — protecting trading strategy from front-running, copytrading, and competitive intelligence exposure.

Execution at Scale

Large orders require more than just a swap interface. A $5M TWAP into a mid-cap token executed naively will move the market, telegraph strategy, and destroy alpha. Definitive's execution tools are designed specifically for large-size onchain trading.

TWAP orders. Time-weighted average price execution breaks large orders into smaller tranches, executed over a defined time window. Parameters are fully configurable — interval duration, tranche size, and time window. TWAP reduces market impact and prevents order telegraphing, both critical for institutional execution.

Limit orders. Set a target price and let Definitive monitor onchain conditions and execute when your price is reached. Limit orders are held onchain — no off-chain matching engine, no counterparty custody.

Stop-loss orders. Define a trigger price for downside protection. When the market hits your stop, the order executes automatically onchain. No manual monitoring required.

Multi-chain execution from one terminal. Manage positions across Base, Arbitrum, Ethereum, Optimism, Polygon, Avalanche, BNB, HyperEVM, and Solana from a single interface. No switching between tools, no fragmented position views.

Routing across 100+ DEXs and 15+ PMMs. Definitive's smart order router evaluates all available venues simultaneously and constructs the optimal execution path. For large orders, this routing advantage translates directly to better fills and lower effective cost.

Reporting and Compliance

Institutional DeFi trading is not just an execution problem — it is also a reporting and compliance problem. Definitive includes post-trade infrastructure that most onchain tools entirely omit.

Post-trade reporting. Every executed order generates a full post-trade record: execution price, fill quantity, routing path, timestamp, and onchain transaction hash. Records are exportable and available for reconciliation, audit, and compliance workflows.

PnL tracking. Definitive's built-in PnL tracking aggregates position performance across chains and assets. Portfolio-level PnL and trade-level attribution are both available, reducing the manual reconciliation burden on back-office teams.

Onchain audit trail. Because every execution is settled onchain, the complete execution record is independently verifiable. Counterparties, auditors, and regulators can verify execution independently — no reliance on self-reported trade confirmations.

Governance and transparency. For investment vehicles with LP or governance obligations, Definitive's reporting provides the trade-level transparency required for periodic reporting. Every trade is attributable, timestamped, and auditable.

This infrastructure matters whether you are a DeFi hedge fund reporting to LPs, a family office subject to compliance oversight, or an OTC desk managing bilateral trading relationships.

Frequently Asked Questions

Does Definitive take custody of assets at any point?

No. Assets never leave your custody. Definitive connects to your existing wallet — Fireblocks, Fordefi, Safe, Squads, or EOA — and constructs transactions that are signed and broadcast through your custody infrastructure. Your keys remain in your control throughout.

How does the Fireblocks integration work in practice?

Definitive initiates a transaction through Fireblocks' API. The transaction is subject to all Fireblocks policy rules — co-signing requirements, spending limits, approval workflows — exactly as you have configured them. Definitive does not bypass or modify any Fireblocks policy. Your custody setup is unchanged.

What is a Performer Address and why would an institution use one?

A Performer Address is a proxy address that Definitive uses to route your order onchain. Your primary wallet address is not visible in the execution transaction — only the Performer Address appears. This prevents front-running, copytrade bots, and competitive intelligence gathering based on your onchain activity. For institutions trading size in competitive markets, this is a meaningful execution advantage.

How does TWAP execution work for large orders?

You define the total order size, the time window for execution, and the tranche interval. Definitive breaks the order into smaller tranches and executes them at regular intervals over the defined window. Each tranche is routed through the smart order router to achieve optimal fill quality. The result is reduced market impact and a final average execution price close to the time-weighted market price over the execution window. See our full TWAP guide for more detail.

What does post-trade reporting include?

Every executed order generates a record including: execution timestamp, asset pair, order type, executed quantity, average execution price, routing path (DEXs and PMMs used), gas cost (zero — Definitive sponsors gas), and onchain transaction hash. PnL tracking aggregates this data across all trades and chains. Records are exportable for reconciliation and compliance purposes.

Is there a minimum trade size or account requirement to access institutional features?

All features — including TWAP, Performer Addresses, Fireblocks/Fordefi/Safe/Squads integration, post-trade reporting, and PnL tracking — are available to all Definitive users from day one. Institutional fee tiers are based on trading volume and staked EDGE; there is no minimum account balance requirement to access any feature.
