Link management

Manage your link.

Every link stays under your control — check its status, extend the expiry, or cancel at any time.

You will need to provide the payment link secret to make changes.

How it works

From link to payment.

You Step 1

Create a link

Choose a chain, pick a stablecoin, set the amount, and provide your wallet address. Get a shareable link in seconds.

You Step 2

Share it

Send the payment link to your payer — via email, invoice, chat, or QR code.

Payer Step 3

Receive directly

The payer opens the checkout and confirms the payment. The decentralized contract moves the funds from their address to yours.

Why stablc

Rules written in code.

Every guarantee is enforced by the smart contract — not by our policy, not by trust in a third party.

Rule I

Non-Custody Rule

Funds move peer-to-peer, directly from the payer's wallet to yours. The contract makes it technically impossible for anyone to hold or touch them.

Rule II

Verification Rule

Every condition is validated on-chain before the transaction executes. If any check fails, nothing moves — no failed txs, no wasted gas.

Rule III

Permanence Rule

Every payment is immutably recorded on-chain. Transaction hash, block, and timestamp are publicly verifiable — forever.

Rule IV

Sovereignty Rule

Your link, your key. Nobody — not us, not any third party — can freeze, cancel, or redirect your payments.

Supported tokens

Stablecoins only.

No volatility, no surprises — only verified digital dollars, approved in the protocol itself.
