What this gets you

Branded payment modal with every major Solana + EVM wallet pre-wired
Smart-funding route engine picks the cheapest path per buyer
Server-signed quotes; merchant address cannot be swapped mid-flow
Demo mode for zero-risk showcasing before you take real funds
MIT license — fork, audit, self-host the backend if you want

No KYC required for buyers. Non-custodial end-to-end.

What's under the hood

Any-wallet, any-chain

Phantom, MetaMask, Backpack, OKX, Rabby, Coinbase, Rainbow, Ledger, plus 17 more — pre-wired across EVM, Solana, Bitcoin, Tron, and Kaspa.

400 ms finality

Solana settles in roughly the time your buyer blinks. Confirmations land before Stripe's ACH has even woken up.

0.35% flat

One fee. No card-network interchange, no FX markup, no account freezes. Every rate is shown to the buyer before they sign.

Conduit Security Score

Every uncurated token is graded in real time — mint authority, freeze authority, honeypot, liquidity, holder concentration. Risky routes warn or block before the buyer can sign.

Live route gating

We probe Jupiter and the EVM aggregators before surfacing a quote. No more 'oops, no liquidity' at broadcast. If it can't settle, we don't show it.

Demo mode built in

Every example has a Demo/Live toggle. Investors and teammates can see the entire flow without touching real funds.

Five runnable examples

Every example is a real page you can open, fork, and ship. Default to Demo mode to explore the full modal without funding; flip to Live when you have a USDC-holding wallet connected.
