Token2022: Solana API now routes Token Extensions

The 0x Solana API now routes swaps involving Token2022 (Token Extensions) tokens. Existing integrations pick this up automatically: no code changes, no new parameter, no version bump.

Teams can now route common Token2022 assets, including PayPal USD (PYUSD), Global Dollar (USDG), tokenized equities, and launchpad tokens.

How it works

To support Token2022, DEX programs added a second instruction variant that includes the token mint account, letting the DEX check which extensions are active before it builds the swap. Solana caps account locks and transaction size per transaction, so carrying that extra account on non-Token2022 swaps adds real, unnecessary cost.

The Solana Swap API routes around that cost automatically. Pairs not involving Token2022 keep using the lean, existing instruction. Only pairs that touch a Token2022 token switch to the mint-aware variant. Every route gets the cheapest instruction set for the tokens it actually contains, so Token2022 support doesn't tax the swaps that don't need it.

What to know

For integrators, request and response shapes are unchanged.

Token2022 routing is live across the major of venues and is extending to the full Token2022-ready DEX set as the remaining venues are enabled. The /enabled-sources endpoint returns the current list.

Use cases

• Stablecoin routing: A wallet quoting PayPal USD (PYUSD) or Global Dollar (USDG) pairs settles them directly through the Solana Swap API instead of dropping the request.
• Tokenized equities: An app offering tokenized securities issued in Token2022 format executes in and out of those assets through the same swap flow it already uses.
• Launchpad tokens: An aggregator integrated with a Solana launchpad routes that launchpad's Token2022 tokens without handling a rejection.
• Bridged assets: A wallet supporting tokens bridged to Solana in Token2022 format routes them exactly as it routes SPL tokens.
