Solana FAQ

The questions Solana engineers actually ask about integrating SODAX.

Do I need to write or deploy a program?

No. SODAX's Solana programs, its on-chain smart contracts, are already deployed and audited; your integration is TypeScript against @sodax/sdk (or the React packages on top of it). You write no on-chain code and take on no program upgrade authority for any part of the flow.

How does a swap from Solana actually settle?

Your user signs one Solana transaction that creates an intent. The SODAX relayer carries proof of that transaction to the hub network (Sonic), a solver fills the intent on the destination network, and the output lands at the recipient address there. Swaps into Solana settle as SPL balances at the user's address. If an intent is never filled, it can be cancelled and the funds recovered.

Which assets are supported on Solana?

Two answers, and the difference matters. On Solana itself, 21 assets are live as of July 2026: SOL, USDC, USDT, bnUSD, SODA, WBTC, ecosystem tokens like BONK, JUP, RAY, PYTH, and JTO, the liquid staking tokens JitoSOL and mSOL, and eight tokenized equities (xStocks). Six of these also work in the money market.

But your users are not limited to those 21. Every swap is cross-network, so from Solana they can reach all 137 assets across every SODAX-supported network (July 2026): SOL into ETH on Ethereum, USDC on Base, BTC on Bitcoin, and so on. The 21 are just the Solana-side entry and exit points. Both lists grow; read them from sodax.config at runtime or check Networks & Assets.

Do my users need a new wallet?

No. Phantom, Backpack, Solflare, and other wallet-standard wallets work through @sodax/wallet-sdk-react (which wraps @solana/wallet-adapter) or directly via SolanaWalletProvider. See Wallets.

Is there an approve step before swapping or supplying?

No. Token allowances are an EVM and Stellar concept. On Solana the SDK's isAllowanceValid check passes without an on-chain transaction, so the quote-to-action path is a single signature.

Can I tune commitment levels and send options?

Yes. SolanaWalletProvider accepts SolanaWalletDefaults: connectionCommitment, connectionConfig, sendOptions, and confirmCommitment. Bring your own RPC endpoint (Helius, Triton, or your own node) via the endpoint field.

What does it cost?

Using SODAX is free: no license, no integration fee, no SDK cost. Trades carry a fixed 0.1% base fee taken by the protocol; on top of that you set your own platform fee and keep it. Your integration is a revenue line, not a cost center. See Monetize SDK.

How do I know if something went wrong?

Every SDK method returns Result<T> rather than throwing. Core swap and money market methods return typed error codes (for example 'RELAY_TIMEOUT', 'EXECUTION_FAILED') you can branch on, with structured context attached.

Where are the audits?

SODAX's Solana programs have their own published report: SODAX (Solana) Smart Contract Audit (Final Report v2). Audits for the rest of the protocol are collected on the Audits page.

Can my AI coding assistant do the integration?

Largely, yes. Add the SODAX Builders MCP to Claude, Cursor, VS Code, Windsurf, or any MCP-capable client (https://builders.sodax.com/mcp) and it gets 40 tools with live access to the SODAX System: chains, tokens, swap quotes, money market rates, intent history, and auto-synced SDK docs. Use it to scope the integration against your own codebase first, then to write and verify the code. Setup per client is at builders.sodax.com.

I want a plan specific to my protocol. Who do I talk to?

Generate a tailored integration guide at sodax.com/solana: paste your protocol's URL and it maps SODAX onto your stack. From there you can reach the BD team directly.
