Build the controls. Manage every transaction.
Compose templates from the Coinbax Controls library, run them on every rail your institution sends on, and monitor every transaction from one place.
Transactions
Pre-Escrow Stage
Checks before funds are locked in escrow

Amount Limit
Validates transaction amount against configurable limits

Pre-Release Stage
Final checks before funds are released
Time Delay
Configurable time delay before funds auto-release from escrow
Set the rules for every phase of a payment
Every payment moves through four enforced phases. You decide which Coinbax Controls run at each one, so a transaction can only advance when your institution's rules are satisfied.
Gate payments before they move
Attach sanctions screening, KYC, and amount limits to the Verify phase. Payments that fail never move.
Hold funds under your rules
At Fund, the payment is set aside under the template’s rules: in your GL on bank rails, or in the escrow contract on chain. Not with Coinbax and not with either party.
Approve or hold before it’s final
Set who signs off, how long the review window runs, and when a liquidity check holds outgoing payments, including nights and weekends when funding is short.
Settle and prove it
The payment goes out on your conditions, and every phase lands in one tamper-evident trail for examination.
Works with your providers, not against them
Coinbax is an added control layer on the transaction, not a rip-and-replace. It plugs into the core, payment hub, custody, stablecoin, and compliance providers your institution already trusts, so you gain programmable controls without leaving the infrastructure you run.

Keep custody with your provider
Coinbax works with MPC wallet and custody providers like Utila to sign and hold funds. Coinbax never takes possession, custody stays exactly where your institution has already placed it.

Settle in regulated stablecoins
Payments settle in USDC and other regulated stablecoins from issuers like Circle, on Base and Ethereum, on the assets your treasury already trusts.

Screen every payment before it moves
Coinbax runs sanctions screening and risk scoring inside the payment flow, through providers like Chainalysis on chain and your existing fraud tools on FedNow and RTP, before funds are committed.
