Hire a Solana payments developer with a production SDK already shipped.

Accepting crypto payments on Solana is straightforward in a tutorial. The parts nobody writes about are where real SDKs live — quote staleness, RPC failover, idempotency, settlement finality. I built Aurion end-to-end: a wallet-agnostic Web3 checkout SDK with Jupiter-routed swaps, multi-RPC failover, and a durable settlement ledger.

Why me specifically

Four concrete reasons.

Wallet-agnostic checkout

Customer pays in whichever SPL token they hold. Merchant settles to a chosen stablecoin. No 'please install Phantom' friction.

Jupiter routing with slippage guards

In-flight swap routing with quote-refresh windows and explicit reject paths when rates move outside tolerance. Silent slippage is the thing that burns merchants; Aurion refuses loudly instead.

Multi-RPC failover

RPC providers go down. Aurion has them behind an abstraction with cooldown and jittered re-test. Sustained failures flip to backup automatically.

Durable idempotent ledger

Settlement state survives process restarts. Retries become reads, not re-runs. No double-charges on client timeout.

What it costs

Real ranges, no back-and-forth.

$20k – $60k

Production Web3 checkout SDK with the above capabilities. 6–12 weeks. More for custom merchant dashboards, compliance overlays, or multi-chain support.

Questions

Asked often enough.

What Solana experience do you have?
I built Aurion SDK end-to-end: wallet-agnostic checkout, Jupiter-routed swaps, multi-RPC failover, idempotent settlement ledger. Production, handling real merchant traffic. I've written publicly about the design decisions.
Do you handle custody?
Aurion settles to the merchant's wallet directly — it does not hold funds. If your model requires custody, we scope that separately and I bring in compliance support.
Multi-chain?
Solana is my specialty. EVM chains can be added as a second pass — scope that separately since the RPC / swap-routing architecture differs.
What stablecoins?
USDC, USDT, and custom SPL tokens. Jupiter covers the routing; the SDK is token-agnostic past that.
