Smart Order Routing
What is SOR ?
Smart Order Routing (SOR) automatically finds the best way to execute your swap across available liquidity on Aptos. Instead of sending your trade through a single pool, SOR may:
Split your order across multiple pools,
Hop through one or more intermediary tokens,
Balance price impact vs. fees to maximize your final output.
Why this matters:
Helps reduce slippage (the gap between quoted and executed price),
Tackles fragmented liquidity by tapping multiple pools,
Improves outcomes during volatile markets.
Where you’ll see SOR in the app
Route Preview: A compact line showing the path (e.g., APT → USDC → TOKEN).
Split Percentages: If your order is split, you’ll see each path’s share (e.g., 60% / 40%).
Best Price Badge: Confirms the app is routing via the most cost-effective path available.
Min. received: The guaranteed minimum after slippage tolerance.
Price Impact and Fees: Estimated effect of your size on pool price + DEX/network fees.
Tip: Click “Hops” in the swap panel to expand the exact hops, split % and amount received through each hops
Quick Start
Select tokens and amount on the Swap page.
Check the quote. You’ll see the route SOR plans to use.
(Optional) Adjust Slippage Tolerance in settings.
Review min. received, price impact, and fees.
Click Swap → Confirm in your Aptos wallet → Wait for on-chain confirmation.
Done! Your received amount appears in your wallet and the app receipt.
Heads-up: Quotes are time-sensitive. If the market moves before you confirm, the app will requote automatically.
How routing works
Single-hop vs Multi-hop: Sometimes going A → B directly is worse than A → C → B. Tapp’s SOR checks both.
Split routing: For larger orders, SOR can spread your trade across multiple pools to lower price impact even after counting extra fees.
Gas/fee-aware: Extra hops aren’t free. SOR weighs the extra cost against the better price and picks whichever leaves you with more output.
Liquidity sources: Tapp’s SOR considers Tapp pools (AMM/CLMM/stable) and whitelisted partner liquidity on Aptos based on availability.
