Built for marketplaces, agencies, SaaS platforms, and service businesses
Use Byhnex when your product needs more than a wallet button. The current program already supports three concrete payment validations: a vault PDA for service escrow, a direct subscription payment flow, and an NFT vault flow for marketplace listings and purchases. Your platform keeps its frontend, branding, onboarding, and business logic while Byhnex handles the on-chain payment layer underneath.
1. Escrow vault PDA for service payments
The program can initialize an escrow state, route the payer funds into a dedicated vault PDA, deduct the platform fee, and release the final amount only when the escrow is validated on-chain. This flow is designed for contracts, freelance jobs, milestones, agencies, and any service marketplace that needs controlled payment release instead of an immediate transfer.
2. Subscription payment validation
The program also supports subscription payments with a dedicated validation flow. A subscriber pays in USDC, the creator receives the net amount, the treasury receives the fee, and the transfer is protected by backend authorization, nonce usage, mint checks, and wallet account validation. This is adapted for SaaS plans, gated services, premium communities, and recurring creator monetization.
3. NFT marketplace vault validation
For marketplace use cases, the program can lock NFTs inside a vault during listing, validate the listing state on-chain, collect buyer payment, split the fee to the treasury, and transfer the NFT to the buyer when the purchase is confirmed. The same flow also supports cancelling a listing and returning the NFT from the vault. This is useful for NFT storefronts, launchpads, secondary markets, and tokenized asset platforms.
4. Public program ID
The current public Solana program identifier used by Byhnex is 4YNNcAsh3kfDXX5SeCPbQxHccjtkTkmw3Qwb62Crsy3d. Use this program ID when building, validating, or verifying instructions against the active Byhnex on-chain program.
5. Core references and required accounts
The integration relies on references such as programId, usdcMint, configPda, escrowStatePda, vaultPda, listingPda, treasury fee accounts, and business identifiers like contractIdU64 or subscriptionIdU64. Depending on the flow, the program validates the vault account, associated token accounts, listing state, treasury fee account, wallet ownership, nonce usage, and backend authorization.
6. What you integrate on your side
You keep your own website, UI, customer journey, and business model. The integration layer connects your product to the Byhnex Solana program so your application can choose the right flow for each business case: service escrow, subscription payment, or NFT marketplace settlement. Your frontend stays native to your brand while the payment validation layer runs on-chain.
7. Fee policy
Byhnex currently applies a 5% platform fee on each funded contract. If you integrate the program, your frontend and backend should reflect this rule when calculating expected payment values, escrow amounts, and final net distribution.
8. Integration note
If you want to use the Byhnex program in your product, align your integration with the canonical program ID, expected escrow and listing accounts, the protocol USDC mint, and the current fee logic. For integration requests, custom setup, or implementation support, contact integrate@byhnex.com.
