Digital asset payments & settlement

Make every asset spendable.

HBridge is settlement infrastructure for digital assets. Your customers pay with any chain, any major coin, any stablecoin. You get one settled balance, in the currency you picked.

18 assets 11 chains 94 payout countries

Payment 2,500.00 USDT
Received on Tron 0.41s
Rate locked 0.24s
Converted to USDC 1.90s
Settled to your treasury 0.60s
You receive 2,500.00 USDC

What they actually hold

Why now

Money stopped being one currency.

Acceptance has not kept up with what people actually own, and the gap widens every time a new chain or a new stablecoin finds liquidity.

A customer in Lagos

Holds USDT on Tron. It is the only dollar they can get, and no rail you have will take it.

A treasury in Singapore

Holds USDC on Base. They can settle in seconds and would rather not route it through a bank.

A desk that holds BTC

Would rather spend it than sell it. Converting first is the only thing in the way.

HBridge accepts all of them, so you never have to guess which one wins.

How it works

Straight from their wallet to your balance.

Acceptance and settlement are two separate decisions, and only one of them should be your customer's.

01 Payment arrives Any asset, any chain.
02 Rate locks Priced the second it lands.
03 Money settles In the currency you keep.
04 Balance updates With a signed confirmation.

One integration

Accept. Convert. Settle. Control.

Accept

Eighteen currencies across 11 chains, plus every major stablecoin. New assets arrive as configuration, never as another integration for you.

Convert

Priced at the moment of payment. Quote, lock and convert in one call, so what you are owed does not move while a block confirms.

Settle

Stablecoin to your wallet, or local currency to your bank. On demand, or on a cadence you set once and forget.

Control

Money settles to an account you name and control. Custody sits in institutional MPC infrastructure, and we never hold a key.

Coverage

94 countries. One settlement layer.

Convert into local currency across our payout network, or keep the whole balance onchain. The destination is a setting, not a project.

Machine pay

The next customer may not be human.

Agents are starting to buy things. When one does, it needs to pay in an asset it holds, prove the payment, and get a receipt. No checkout page, no card, nobody watching.

HBridge settles agent-initiated payments over x402 on the same rails, into the same balance, with no second integration.

You don't have to bet on when this becomes normal. You're already connected to it.

Developers

One API to accept, convert and pay out.

Create a charge, watch it settle, move your money out. Signed webhooks on every state change. Sandbox and live take the same request, so you go live by changing a key.

create-charge.sh
# sandbox and live use the same shape
curl https://api.hbridge.io/v1/charges \
  -H "Authorization: Bearer $HBRIDGE_KEY" \
  -d '{
    "amount":   "2500.00",
    "currency": "USD",
    "accept":   ["USDT", "USDC", "BTC"],
    "settle":   { "asset": "USDC" }
  }'

Who it's for

Who gets paid this way.

Exchanges & brokers Let users fund accounts in any asset. Hold one.
Marketplaces Pay sellers across borders without prefunding every corridor.
Remittance Collect in stablecoins, pay out in local currency.
Digital goods & SaaS Take crypto without ever touching custody.
Treasury teams Convert every incoming asset on a policy, not by hand.
Agent developers Machine-initiated payments over x402, on the rails you already use.

Questions

The things everyone asks.

Do our customers need to understand crypto?

They need a wallet and an address. You show them the address we give you, and nothing else changes in your product.

Which asset do we end up holding?

Whichever one you choose. Your customer picks what they send, you pick what you keep, and the two never have to match.

Who carries the price movement?

Not you. The rate is quoted and locked when the payment lands, so what you are owed does not move while the block confirms.

Where do the keys live?

In institutional MPC custody, never on our servers. Money settles to a destination you designate and control.

What does adding a new asset cost us?

Nothing. Chain and token support is configuration on our side, so you never integrate a second time.

Let your customers pay with what they already have.
