Non-custodial · No KYC

From link to payment —
here's exactly how it works.

No bank, no processor, no intermediary. A URL and a smart contract are all it takes to move money directly between two wallets.

You Create link

checkout.stablc.xyz/p/…

Payment link Share via any channel

Payer Connects wallet

Smart contract Routes on-chain

Your wallet Funds received

What the payer sees

Your payer opens the link in any browser. No app download, no account creation. They connect their existing wallet and confirm one transaction.

01 Opens the link — sees amount, recipient, note, expiry
02 Connects their wallet (MetaMask, Coinbase, WalletConnect…)
03 Approves the token spend (one-time per token)
04 Confirms the payment — on-chain in seconds

The entire payer experience happens at checkout.stablc.xyz/p/{linkId} — nothing to host.
