Every crypto exchanger eventually hits the same question: where to keep the wallets and who processes the payments. The easy path is to plug in a third-party processor. Over time, it's also the expensive one. iEXWallet offers a different route — a payment gateway you deploy on your own server, depending on no one.
The trouble with someone else's processor
When an exchanger runs on an external wallet service, it hands away the one thing that matters most: control. Private keys sit with the provider, the fee is often a percentage of turnover, and the operation history lives in someone else's database. Any outage, freeze, or pricing change on their side instantly becomes your problem. In effect, the business rents what should be its own foundation.
What iEXWallet does
iEXWallet isn't a consumer wallet — it's server-side infrastructure for accepting and sending crypto. You install it on your dedicated server, and from there everything — keys, funds, addresses, operation logs — stays only with you. No revenue share, no dependence on an outside platform. At launch it supports 9 networks (TRON, TON, Ethereum, Polygon, Solana, Bitcoin, Litecoin, BNB Chain, XRP) and more than 20 coins and tokens, including USDT and USDC.
Four wallets instead of one
The core engineering idea is to split funds by purpose. Instead of a single "shared" wallet, the system uses four types: hot for current payouts, working for the operational flow, cold for the main reserve, and a separate energy wallet. The last one is a small touch that saves real money: it holds TRON energy, so USDT-TRC20 transfers go out at almost no fee. For an exchanger with heavy stablecoin volume, that's tangible savings every day.
Security and compliance built in
Control here isn't just a slogan. Private keys are stored encrypted on your own infrastructure, admin access is protected by two-factor authentication and an IP whitelist. There's multi-signature across EVM and UTXO chains, withdrawal limits (daily and weekly), a full audit log of every staff action, and multi-person payout approval with roles. For counterparty checks, AML scoring and address blacklists are built in — the things a serious exchanger simply can't operate without today.
Under the hood
iEXWallet is a self-contained build: a NestJS backend, a PostgreSQL database, Redis job queues, and a React interface with real-time updates. Inside there's automatic deposit detection and confirmation tracking, transaction batching to cut network fees, automatic failover when a provider goes down, and liquidity forecasting. Rates are pulled from Binance, ByBit, and CoinGecko, and alerts arrive via Telegram and email.
Who it's for
First of all, operators of crypto exchangers, payment services, and money transfers who need self-custody infrastructure with serious monitoring and compliance — not a black box holding someone else's keys. When volume grows and dependence on an external processor starts to get in the way, that's exactly when running your own gateway pays off.
In short
iEXWallet solves a simple but costly pain: stop renting other people's wallets and take control of your money and data back. Nine networks, four wallet types, AML and multisig out of the box — all on your own server. You can learn more and deploy it on the iEXWallet page.
