0x Swap API on Solana is now in open beta

0x Swap API on Solana is now in open beta. Just create an account, get your API key, and start routing trades on Solana today.

Existing 0x integrators expanding to Solana can add Solana routing while keeping the transaction infrastructure and operational model they already run. Solana-native teams can add 0x as a route provider while retaining control over transaction assembly, signing, and submission.

0x is best known for its leading aggregation stack on EVM chains. As the first non-EVM network supported by 0x Swap API, Swap API on Solana is informed by over 9 years of experience developing and optimizing onchain trading tools. Solana teams benefit from ready-to-assemble routing and can submit transactions that fit their workflow, with high performance and reliable execution. Try it now with an exclusive introductory offer of zero swap fees.

Execution that lands reliably

Swap routing is usually decided based on the price quoted, not the amount it actually executes at. Too often, that quoted price is a promise that will not be fulfilled. The amount a user keeps depends on whether the trade actually executes, and how far the settled amount drifts from the quote.

0x optimizes for the settled outcome, with 0x quotes survives simulation 97.8% of the time, higher than any other aggregator. It also leads with low revert rates (2.2%) in real-world usage, excels on the pairs where the difference between quoted price and executed price tends to see most drift, and outperforms in the high-value $10,000 to $100,000 bracket, all of which delivers consistent value to your end users.

Proven real-world performance

Two of Solana’s leading products, Kamino and Titan, have both been routing through the Swap API during the closed beta, with strong results.

Kamino, a lending protocol, uses 0x for actions requiring a swap, such as opening or unwinding a position, for a single execution standard across its app. Titan, a meta-aggregator, makes providers compete for the settled amount that lands in a user's wallet, not the amount quoted upfront. Both set a high bar for execution, and both chose to route through 0x.

Matcha Meta, a meta-aggregator built by 0x, has also settled millions of dollars in volume on Solana during beta, offering more proof points to the routing quality of the Swap API and enabling in-house optimization that continues after GA.

Coverage across SPL, native SOL, and Token2022

All swaps on Swap API on Solana route through the same endpoint, from standard SPL mints, to native SOL and Wrapped SOL, and Token2022 assets. Native SOL is handled in and out without a separate wrap step.

Token2022 routing went live in July and is extending across the Token2022-ready venue set. It covers stablecoins, tokenized equities, and launchpad tokens, with no code change needed.
Coverage continues to expand as additional liquidity sources are enabled. Integrators can review the current list of enabled Solana sources before testing or launching new token pairs.

Ready for your workflow

On Solana, each transaction is a list of instructions executed atomically. Returning a fully assembled transaction would take away your ability to add your own, so the API returns routing and instructions that fit into the transaction pipeline your team already operates:

• One endpoint. POST /solana/swap-instructions returns the quote, the full route plan, and the instructions to sign.
• Address Lookup Table support. ALTs are returned so complex multi-hop routes compile into compact transactions within Solana's account and size limits.
• Reserved transaction bytes. reserve_transaction_bytes keeps space free so your own instructions, from fee logic to position entry and unwind, fit in the same atomic transaction.
• Swap and send. A recipient parameter routes swap output to an address other than the taker in the same transaction.
• Token accounts handled. The taker's associated token accounts are created as part of the instruction set.
• Slippage control. Use slippage_bps to set your slippage tolerance, default 50 bps (0.5%).

0x does not submit the transaction, suggest priority fees, or set the compute budget. We know teams running meaningful volume on Solana already own those decisions and tune them to their own infrastructure, so you have full control over these details.

Monetization options

Monetizing a product built with Swap API Solana is as easy as specifying a percentage fee on either side of the swap, to one or more recipients, as request parameters.

Multiple fee recipients can be specified in a single swap, built to handle an app-and-referrer revenue split without separate fee-transfer logic. And with our introductory no-fee offer, your team gets to keep the full fee amount.
