Definitive is an onchain trading terminal with native Base network support. It gives Base traders free trading on major assets and stablecoins, gasless execution across all tokens, advanced order types — TWAP, limit, stop-loss, and market — and smart routing across all Base DEXs. Whether you are a DeFi power user, an active trader in the Base ecosystem, or a builder managing protocol funds, Definitive gives you the professional execution layer that Base's growing ecosystem demands.
Base is one of the fastest-growing chains in crypto. Built by Coinbase, it offers Ethereum security with low transaction costs and a rapidly expanding DeFi ecosystem. But as Base's DEX liquidity, token diversity, and user base have grown, the gap between what retail tools offer and what professional traders need has widened.
Simple swap interfaces work for casual users. Active Base traders — managing larger positions, executing DCA strategies, protecting downside with stops, or building positions gradually — need execution infrastructure those tools do not provide.
Definitive's Base integration is native and full-featured. Every order type is available on Base. Gasless execution applies on Base the same as on all nine supported chains. Smart routing scans all Base DEX liquidity for best execution. Post-trade reporting captures every fill in detail.
Free on majors and stablecoins. Definitive charges zero fees on major assets and stablecoins on Base. ETH, USDC, WBTC, and other major pairs trade completely free of charge. For traders whose activity is primarily concentrated in large-cap Base assets, the effective fee is zero.
One terminal, nine chains. Base traders managing positions across chains can access Arbitrum, Ethereum, Optimism, Polygon, Avalanche, BNB, HyperEVM, and Solana from the same interface. One account, one view, no tool switching.
Definitive was founded by Coinbase Institutional Trading alumni — the Base ecosystem is not an afterthought. It is built into the product's foundation.
Gas is effectively free on Base by Layer 1 standards — but it is not literally zero. ETH for gas must be held in wallets, managed across addresses, and topped up when balances run low. For traders running automated strategies with many executions, managing gas is a persistent operational overhead.
Definitive eliminates it entirely. Gas is sponsored by Definitive on Base — every order, every TWAP tranche, every limit order fill, every stop-loss trigger executes with zero gas cost to you.
Why gasless matters for Base traders specifically:
TWAP orders on Base may execute dozens of individual transactions over an extended window. A 12-hour TWAP with 15-minute intervals generates 48 separate transactions. Gas-free execution means none of those transactions cost you anything — and none of them can fail due to insufficient gas balance.
Limit and stop-loss orders require monitoring and execution at uncertain future times. If your ETH gas balance drops before a limit order fills, the order may not execute. Definitive's sponsored gas removes this failure mode — your orders execute when conditions are met, regardless of your gas balance.
For traders managing multiple strategies simultaneously across Base, gasless execution simplifies wallet management significantly. No gas wallets to maintain. No ETH reserves to monitor. Trade your assets — Definitive handles the transaction fees.

Base traders deserve the same order type sophistication available to institutional traders on EVM — not just a market swap button. Definitive delivers four order types, all onchain, all on Base.
TWAP (Time-Weighted Average Price). Executing a large Base position in a single market order moves the price against you and signals your intent to the market. TWAP execution solves both problems. Define your total order size, time window, and execution interval — Definitive breaks the order into tranches and executes them automatically. Market impact is minimized across each tranche, and your aggregate execution price is smoothed over time.
Use cases on Base: building a position in a Base DeFi token over 24 hours, exiting a large LP position into stablecoins, converting protocol revenue into ETH over a defined window.
Limit Orders. Set an exact price at which you want to buy or sell on Base. Definitive monitors onchain conditions and executes automatically when your price is reached — onchain settlement, no off-chain matching engine. Useful for establishing positions at target entry prices, taking profit at specific levels, or building systematic DCA strategies without manual execution.
Stop-Loss Orders. Define a downside exit price and protect your Base positions automatically. When the market hits your stop, Definitive executes the exit onchain without requiring manual monitoring. For volatile Base assets — new protocol tokens, ecosystem plays, leveraged positions — automatic stop-loss execution provides protection that manual monitoring cannot reliably deliver.
Market Orders. Fast execution across all available Base liquidity with smart routing for best fill. When speed matters more than price optimization, market orders execute immediately.
All four order types are onchain on Base — no off-chain components, no custody compromise, no trust required beyond the smart contracts.
Execution quality on Base depends on routing. Base's DEX ecosystem includes multiple venues with different liquidity profiles — and the best price for any given pair depends on how intelligently you route across them.
Definitive's smart order router evaluates all available Base DEX liquidity simultaneously at the time of every execution. It does not use a static routing preference or a single-venue default — it finds the optimal path for your specific order, size, and market conditions in real time.
Split execution for large orders. For orders that would cause significant price impact in a single pool, Definitive splits execution across multiple venues simultaneously. Each portion is filled at the best available price for that size in that venue — the aggregate result is a better weighted average execution price than any single-venue route would achieve.
Offchain PMM routing included. In addition to Base DEX pools, Definitive routes through 15+ offchain professional market makers. For major assets — ETH, USDC, WBTC — PMM liquidity often provides competitive or superior pricing to DEX pool routing.
Routing transparency. Every executed order shows the complete routing path: which venues were used, what proportion was allocated to each, and the final average execution price. You see exactly how your order was filled and why.
Continuous routing quality. For TWAP orders executing multiple tranches, routing is re-evaluated at each tranche execution — using current market conditions, not conditions from when the order was placed. Your TWAP adapts to market reality in real time.
Connecting to Definitive on Base is straightforward — no new wallets, no bridges, no complicated setup.

Major assets and stablecoins on Base trade with zero fees on Definitive. This includes ETH, USDC, WBTC, and other large-cap tokens and stablecoin pairs. For less established Base assets, fees start at 85 bps and decrease based on volume tier and staked EDGE.
You configure the total order size, the asset pair, the execution window, and the interval between tranches. Definitive handles the rest — splitting the order, executing each tranche on schedule, routing each one for best fill across all available Base DEX liquidity and offchain PMMs. The result is a time-weighted average execution price with significantly lower market impact than a single large market order. See our full TWAP guide for details.
Yes. Definitive integrates natively with Safe on Base and all EVM chains. Transactions you initiate through Definitive are presented to your Safe multisig queue for approval by required signers. Your threshold configuration, role permissions, and approval workflows are fully preserved.
Yes. Gas sponsorship applies to all order types on Base — market orders, limit orders, stop-loss orders, and all individual TWAP tranche executions. You pay zero gas on all Definitive transactions on Base.
Yes. Definitive is a multichain terminal — all nine supported chains are accessible from a single interface. You can hold positions on Base, Arbitrum, and Solana simultaneously, view aggregate PnL across all chains, and execute orders on any chain without switching tools or accounts.
Every executed Base trade generates a record with: asset pair, order type, executed quantity, average execution price, routing path (DEXs and PMMs used), execution timestamp, and Base transaction hash. PnL tracking aggregates all Base trade performance. Records are exportable for reconciliation, reporting, and personal records.
Trade Base like a professional. Connect your wallet — free on majors, gasless on everything.
