Accept stablecoins & cards
Get paid in USDT & USDC via payment links, checkout, or per-invoice addresses. Prefer cards? Let customers pay by card through your own Stripe account, in the same checkout.
Sendbase for Business
A self-custodial stablecoin account for your business
Accept USDT & USDC, pay out on your schedule, automate with a Stripe-compatible API, and give AI agents their own spend-capped wallet, all without giving up custody of your keys.
Features
Everything you need to get paid in stablecoins
Stripe-compatible API
Drop-in checkout sessions, charges, idempotency keys, and signed webhooks that mirror Stripe. Keep your integration, just swap the keys.
AI Agent Wallet
Give an AI agent its own wallet with per-transaction, daily and monthly caps plus an address allowlist. It pays autonomously. You set the limits.
x402 agent payments
Charge AI agents per call. Return an HTTP 402, the agent pays in USDT or USDC, you verify and serve. No cards, no sign-ups, machine-speed settlement.
Recurring billing
Set up subscriptions that email your customer a fresh pay link every cycle, weekly, monthly, or yearly, with receipts sent automatically.
Full & partial refunds
Refund a customer in a click, full or partial, straight back to their original wallet. Non-custodial: you sign the send-back, gas is sponsored, and Sendbase never touches the money.
Payouts & statements
Sweep collected funds whenever you choose, and export PDF receipts, invoices, and bank-style account statements for your records.
On-ramp & off-ramp
Swap USDT for local currency with trusted counterparties you invite by email, protected by on-chain escrow. Learn more.
Self-custodial by default
Keys are generated on your device with a 24-word backup, passkey, and 2FA. Sendbase never holds, freezes, or controls your funds.
Free to open · pay only when you get paid · self-custodial

Security by design
Your funds stay yours, always
Sendbase is self-custodial from the ground up. Your company wallet keys are generated on your device and split into encrypted shares, so the server can never reconstruct or sign with them. Funds settle to a wallet Sendbase cannot drain, freeze, or divert.
- Keys on your device. Split into encrypted shares; Sendbase only ever holds a share it cannot reconstruct or sign with.
- 24-word backup, passkey & 2FA. Export to any EVM wallet at any time. Your account is portable and yours.
- Verifiable on-chain. Every payment, payout, and refund settles on BNB Smart Chain and is provable on BscScan.
Live on BNB Smart Chain mainnet. See our on-chain escrow contract on BscScan.
