Changelog: October 2025

Major improvements to quoting and swap execution in the Ultra Swap API. Read the full technical deep dive.

• Improved routers in meta aggregation - granular splitting of 0.01%, and Golden-section and Brent's method for routing algorithms
• Ultra Signaling for tighter prop AMM quotes - Ultra signals to prop AMMs, letting them confidently quote tighter by distinguishing Ultra trades as "non-toxic" order flow: 3 bps tighter (50% better) quotes for Ultra users compared to other platforms
• Predictive Execution - simulates routes on-chain to verify executable price versus quote and predict potential slippage, selecting the route with the least overall incurred slippage at execution time
• Jupiter Beam - transaction sending infrastructure that reduces landing time by 50-66% compared to traditional methods and reduces MEV opportunities by 34x
• RTSE optimisations - automatically prioritises slippage-protected routes over purely price-optimised routes, with increased volatility sensitivity for tokens with high historical volatility
• Gasless support coverage - expanded to Token2022 tokens and memecoin-to-memecoin swaps (when liquidity permits), with minimum trade size reduced to ~$10 USD
• Just-in-time market revival - dynamically re-indexes markets to enable tradability for all tokens
• Reduced pre-graduation quote latency - optimised bonding curve market routing by skipping multi-route aggregation, improving quote latency from 200ms to 10ms

Try the Ultra Swap API

route_v2, exact_out_route_v2, shared_accounts_route_v2, and shared_accounts_exact_out_route_v2. Details in the latest IDL on Solscan. V1 instructions remain valid and usable.

WTM (what this means) - The V2 instructions enable collecting fees when the swap pair includes a Token2022 mint, and setting fees beyond the previous 255 bps cap.

Ultra Swap API: no additional parameters required, create Token2022 referral token accounts for your referral account. See Add Fees To Ultra Swap.

Metis Swap API: a new instructionVersion parameter on the quote endpoint supports the new instruction types; create Token2022 token accounts and pass them via feeAccount. See Add Fees To Swap.
