Web3E

Web3E is a developer-first crypto payment gateway for online businesses. It lets merchants accept stablecoins and native coins across 14 blockchains while keeping control of their own funds — non-custodial by default, with an optional custodial mode for merchants who'd rather Web3E hold the balance.

Instead of routing customer payments through a pooled provider wallet, Web3E issues a unique deposit address per invoice and watches the chain directly. Customers pay from any wallet on the network they choose; Web3E detects the transaction, tracks confirmations, locks the exchange rate for the payment window, screens the sender for AML risk, and reports the result to your system over a signed webhook.

Key features:

• Non-custodial by default — funds settle straight to a wallet you control; custodial mode available as an option.
• 14 chains — stablecoins (USDT / USDC / DAI) and native coins on Tron, Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, Solana, XRP Ledger, TON, Bitcoin, Litecoin and Dogecoin.
• Full payment lifecycle — confirmations, under- and overpayments, expired invoices and chain reorganizations are all handled; nothing is silently dropped.
• Signed, replay-proof IPN webhooks — HMAC-signed with a delivery id, timestamp and rotatable secret.
• Built-in AML screening — deposit senders and payout addresses checked against sanctions and on-chain risk lists.
• One REST API + hosted checkout — integrate programmatically, or send buyers to a ready-made payment page.
• Batch crypto payouts and settlement reporting in the currency you choose.

Pricing is fee-only: a per-transaction commission (from 2%) with no setup or monthly fee.

Web3E is for businesses that want the convenience of a hosted crypto processor without giving up custody of their money — an alternative to custodial payment processors and to building blockchain payment infrastructure in-house.
