Overview
SettleBolt lets businesses create payment links and invoices for stablecoin payments. The customer pays on-chain. Funds settle directly to the merchant wallet that is verified in the dashboard.
SettleBolt does not hold merchant or customer funds.
Share links at settlebolt.com/l/..., settlebolt.com/pay/..., or your custom domain.
Stripe is used only for SettleBolt subscription fees.
SettleBolt does not automatically pull crypto from a customer's wallet, hold balances, exchange tokens, or custody funds. Customer payments are initiated by the payer and recorded after chain confirmation.
Quick Start
After signup, enter the 6-digit code before accessing the dashboard. You can resend once every 3 minutes, up to 3 resends.
Go to Wallet, add a wallet, and verify it. EVM wallets can be verified by signature or added as receive-only with confirmation.
In Settings, add legal name, VAT/tax ID, registration number, business email, website, and address. These details appear on invoices and branding previews.
Use Payment Links for reusable checkout links, or Invoices for customer-specific billing with line items, due date, and email delivery.
Payments appear in Payments after the watcher sees a supported transfer to your verified wallet and enough confirmations have passed.

Wallets and Chains
Your wallet is your settlement destination. A payment link or invoice only works when the selected chain has a verified primary receiving wallet.
Base, Ethereum, Arbitrum, Optimism, Polygon, Avalanche, zkSync Era, Linea, and Scroll. Pay with the stablecoins USDC, USDT, and DAI where each is enabled in the registry.
Bitcoin — native BTC. Solana — native SOL plus USDC and USDT. Tron — native TRX plus USDT. These use self-attested receive-only addresses in v1: you paste and confirm the address (on-chain signature verification is a fast-follow).
Stablecoins USDC / USDT / DAI (EVM), USDC / USDT (Solana), USDT (Tron); and native BTC, SOL, and TRX, which are quoted live at checkout. Native ETH is defined in the system but is not currently enabled as a payable asset.
Add a wallet
- Open Wallet in the dashboard.
- Choose a chain and enter a wallet name if you want one.
- For browser wallets, sign the challenge. For receive-only addresses, paste the exact address and confirm it.
- Set a primary wallet per chain when you have more than one verified address.
Changing a primary payout wallet is delayed by 24 hours. Admins can freeze payout changes if an account looks risky.
Payment Links
Payment links are reusable hosted checkout URLs for fixed EUR amounts. Customers pay in the token and chain you select, and SettleBolt records the on-chain payment when it confirms.
Create a payment link
- Go to Payment Links and click New payment link.
- Enter title, optional description, amount, token, and chain.
- Save the link and copy the checkout URL.
- Share it with your customer.
| Field | Rule |
|---|---|
| Title | Required, up to 120 characters. |
| Description | Optional, up to 500 characters. |
| Amount | EUR cents, minimum EUR 0.01, maximum EUR 1,000,000. |
| Status | Active links can be paid. Inactive or deleted links cannot be paid. |
You can edit a link, deactivate it, reactivate it, copy it, view its payments, or delete it. Deleting is a soft delete: the link is hidden and its active quotes are expired.
Invoices
Invoices are customer-specific bills with line items, due dates, and a hosted pay page. They start as drafts, then become sent invoices when emailed to the customer.
Create and send an invoice
- Open Invoices and click New invoice.
- Add customer name and email. If you already added the customer, use the customer record.
- Use the suggested invoice number or enter your own unique number.
- Choose currency EUR, token, chain, due date, and line items.
- Click Save draft to keep editing, or Save and send to email the pay link.
Editable. Does not require a verified wallet until you send it.
Can be resent or cancelled. The customer can pay via the invoice checkout page.
Locked after settlement. It counts toward the paid invoice limit for the month.
No longer payable. Use a new invoice if you need to bill again.
The invoice amount must match the line item total when line items are present. PDF/printable invoice output includes available business and customer billing details.
Customers
Customers appear automatically when you invoice them. You can also add manual contacts before billing them.
First name, middle name, last name, email, phone, and profile notes.
Company/legal name, billing contact, billing email, phone, address, tax status, VAT/tax ID, registration number, and invoice defaults.
Tax status
Business customers can be marked as Taxable, Exempt, or Reverse charge. Use the status your accountant expects for that customer's location and tax relationship.
Customer detail pages show total billed, paid, outstanding, average invoice, invoices, and payments. Removing a manual contact removes the saved contact profile, not historical invoices or payments.
Payments
The Payments ledger shows confirmed, pending, underpaid, overpaid, failed, invoice, link, and direct payments. You can filter by date, status, token, chain, source, transaction hash, or payer address.
SettleBolt records payments by verified recipient wallet. If exactly one open invoice or link matches the received amount, it attaches automatically. If no target or multiple targets match, it stays direct so the wrong invoice is not marked paid.
Refunds
Because SettleBolt is non-custodial, refunds are manual on-chain transfers from your wallet back to the customer. The payment detail view shows the payer address and transaction hash to help you refund correctly.
CSV exports are available on paid plans where exports are enabled.
Branding and Custom Domains
Branding controls how checkout, invoices, receipts, and the customer portal look. It is available on Pro and Business.
| Asset | Rule | Suggestion |
|---|---|---|
| Logo | PNG up to 2 MB. Transparency is recommended, not required. | 600 x 240 px |
| Icon | Square PNG up to 2 MB. Transparency is recommended. | 512 x 512 px |
| Colors | Use valid hex colors such as #0B0B0C. | Brand color for headers, accent color for buttons. |
Custom checkout domain
- Use Pro or Business.
- Open Branding, enter a domain you own, such as
pay.yourbrand.com. - Add the CNAME record shown in the dashboard. The default target is
settlebolt.pages.dev. - If the dashboard shows TXT validation, add that TXT record too.
- Wait for Cloudflare certificate validation to complete.
Do not use settlebolt.com or a *.settlebolt.com hostname as your custom domain.
Team Access
| Role | Access |
|---|---|
| Owner | Full access, billing, team management, ownership transfer, and account deletion. |
| Admin | Manages team, links, invoices, payments, wallet, branding, and settings, except owner-only actions. |
| Member | Manages payment links, invoices, customers, and payments. |
| Viewer | Read-only dashboard access. |
Invites are emailed to teammates. Removing a teammate revokes their sessions for this merchant account. Starter includes 1 seat, Pro includes 3, and Business includes 10.
Billing
Billing is for the SettleBolt SaaS subscription only. Stripe charges your card for monthly or annual software access. It does not process your customers' crypto payments.
- Change plan: choose Starter, Pro, or Business and monthly or annual billing.
- Cancel subscription: cancellation stops renewal immediately, and you will not be charged again for that subscription.
- Reactivate: available when a cancelled subscription can still be resumed.
- Receipts: view and email SettleBolt subscription receipts from Billing.
- Billing history: admins can view purchases, downgrades, checkout starts, plan changes, and receipts from the admin dashboard.
Help, Tickets, and Feedback
The dashboard sidebar includes Help and Feedback near the bottom.
Create support tickets, view active tickets, and open a ticket detail thread.
Send product feedback, bugs, ideas, praise, and an optional 1-5 rating.
Ticket categories are General, Billing, Payments, Wallets, Technical, and Security. Priorities are Normal, Low, High, and Urgent. Ticket subjects can be up to 140 characters and messages up to 4,000 characters.
Analytics
Analytics is available on Pro and Business. It shows total volume, payment count, average payment, average invoice, time series, by-token breakdown, by-chain breakdown, top customers, and top payment links.
Supported ranges include 7D, MTD, 30D, 90D, YTD, 12M, and Custom. Empty states stay quiet when there is no activity in the selected range.
API Overview
The production API base is:
https://api.settlebolt.comDashboard routes use the authenticated dashboard session token:
Authorization: Bearer <dashboard-session-token>
Content-Type: application/jsonOnly accounts with an active paid Pro or Business billing period can create, revoke, or use API keys. API keys are for SettleBolt's dedicated, scoped server-to-server Agent API (/api/agent/*) — each key carries per-operation scopes (for example invoices:create, payments:read). They are not accepted on dashboard routes, so a key can never manage wallets, billing, team, or account settings. Keys are shown once; treat them like passwords and revoke a leaked key in Developers. Do not expose dashboard session tokens in public client code.
Developers also includes a WhatsApp agent channel for Pro and Business accounts. A merchant creates a 10-minute pairing code, sends link 123456 from WhatsApp, and that WhatsApp sender can then use only the selected safe agent scopes. WhatsApp cannot manage wallets, billing, team access, or account deletion.
For the endpoint table, examples, webhook signatures, and payload shapes, open the dedicated API and webhook reference.
Webhooks
Webhooks are available only during an active paid Pro or Business billing period. Add an HTTPS endpoint in Developers, copy the signing secret once, and verify every delivery.
When a payment is recorded on-chain, SettleBolt sends a signed payment.confirmed POST to each of your active endpoints. Failed deliveries are retried with backoff (up to 6 attempts) and every attempt is visible in the delivery log, where you can also redeliver by hand.
X-SettleBolt-Event: payment.confirmed
X-SettleBolt-Event-Id: evt_...
X-SettleBolt-Timestamp: 1783100000
X-SettleBolt-Signature: t=1783100000,v1=<hmac>The signature is HMAC-SHA256 over:
<timestamp>.<event_id>.<raw_json_body>Webhook URLs must be public HTTPS endpoints on port 443. Internal, loopback, link-local, metadata, credentialed, IPv6 literal, and non-443 URLs are rejected.
Security Checklist
- Verify your email before using the dashboard.
- Enable 2FA in Settings.
- Name wallets clearly so payout destinations are easy to inspect.
- Use separate support/admin accounts instead of shared logins.
- Keep API keys and webhook secrets in server-side secret storage.
- Verify webhook signatures and reject stale timestamps.
- Use HTTPS-only webhook endpoints.
- Review Billing and Support history after plan or access changes.
Troubleshooting
Payment is not showing
Check that the customer paid the exact token and chain on the checkout page, that the recipient address is your verified primary wallet for that chain, and that enough confirmations have passed.
Invoice cannot be sent
The invoice chain needs a verified wallet before sending. Draft invoices can be saved before a wallet is connected.
Custom domain is pending
Confirm the CNAME target and any TXT validation records exactly match the Branding screen. Certificate validation can take time after DNS propagation.
Customer did not get an invoice email
Use Resend on sent or overdue invoices. Also confirm the customer email is valid and check spam/quarantine filters.
Need help
Open Help in the dashboard, create a ticket, and include invoice IDs, link URLs, wallet addresses, transaction hashes, and screenshots when relevant.
