How does settlement work?

Settlement

Once a payment is confirmed on-chain, it is automatically settled to your account. You can choose to settle in a stablecoin (e.g. USDC) or convert to your local fiat currency. Settlements are processed instantly.

What security measures are in place?

Security

We follow industry-standard security practices: data is encrypted in transit and at rest, integrations are authenticated, keys and credentials are stored securely with strict access controls, and systems are continuously monitored. We also perform regular security reviews, testing, and third-party audits.

What are the fees?

Pricing

CoinCircuit charges a simple flat fee per transaction — no monthly minimums, no setup fees, no integration fees, and no charges for failed or expired payment sessions.

Do you support partial payments?

Features

Yes. If a customer sends less than the required amount, the session stays open until the full balance is received or the session expires. This is useful for large invoices or customers splitting payments across wallets.

Can I accept crypto payments in Nigeria?
