Top Up Tangem Pay from your bank (ACH and FedWire)
Tangem Pay now accepts direct bank transfers. Each payment account has its own US bank details. Users top up their accounts via ACH or FedWire from a US bank. Future updates will include offramping, allowing users to offramp directly to their bank accounts.
What are ACH and FedWire?
ACH is the Automated Clearing House network. It groups transfers into batches and settles them during scheduled runs, which makes it low-cost and well-suited to routine payments.
FedWire is the Federal Reserve's real-time gross settlement system. It settles each transfer individually and immediately, making it well-suited to large or urgent payments.
Both are core US payment rails. In 2024, the ACH network processed approximately 33 billion transfers, and FedWire processed approximately 210 million transfers, each averaging approximately 5.3 million US dollars.
Tangem Pay now supports both top-ups. Users choose what matches the amount and the urgency of each top-up.
The table below shows how the two options differ, and what each costs as a Tangem Pay top-up.
| Feature | ACH | FedWire |
|---|---|---|
Tangem Pay top-up fee | 1 US dollar per transfer | 11 US dollars per transfer |
How it settles | Batched, then settled in scheduled runs | Settled one transfer at a time, in real time |
Typical settlement time | 1 to 3 business days | Same business day, often within hours |
Availability | Submitted at any time, settled on business days | Business days only, within Federal Reserve operating hours |
Finality | Returns are possible within the network rules | Irrevocable once settled |
Best suited to | Routine and recurring top-ups where cost matters | Large or time-critical top-ups where speed matters |
Arrives as | USDC on Polygon at a rate of 1 to 1 | USDC on Polygon at a rate of 1 to 1 |
How it works
Each payment account receives its own US virtual account details. You share these details the same way you share bank account details. Incoming fiat converts to USDC on Polygon at a 1-to-1 rate. One US dollar becomes one USDC, and the funds land in the Tangem Pay account, ready to use.
A flat commission applies to each top-up. ACH costs 1 US dollar, and FedWire costs 11 US dollars. The commission is deducted from the transfer amount. To receive 1000 USDC via ACH, the sender sends 1001 USD. By FedWire, the sender sends 1011 US dollars.
Availability and requirements
The feature needs a Tangem Pay payment account, and a payment account needs KYC. Availability follows the country in the user KYC data, not the IP address.
The feature uses US bank rails. Senders can transfer from many locations, provided their bank supports ACH or FedWire.
SWIFT transfers to these details do not work. A SWIFT transfer will return to the sender's account.
Eligible users see bank transfer as an added top-up option appearing next to the existing top-up methods.
Benefits of ACH/ Fedwire onramps to Tangem Pay
A shorter path into crypto
You move funds straight from your bank into a spendable balance. There’s no exchange account to open, fund, or withdraw from. You never hold a balance with an exchange at any point. The mechanics feel familiar. You simply send a normal bank transfer to a regular US bank account.
Funds arrive ready to use
Your balance sits in the payment account as USDC on Polygon. You can pay with the card wherever Visa is accepted, online and in-store. You can also put the same balance into Yield Mode or swap it into another asset.
Funding doesn’t lock you into one use. Your balance is held in a smart contract account that you control, and any unused USDC can be withdrawn to your Tangem Wallet.
Receive recurring payments
Share your account details with a payer, such as your employer, to receive regular payments directly into your Tangem Pay account. Incoming funds arrive as USDC on Polygon, ready for you to hold, deploy, or spend with the card.
Fund and grow
Top up at a low flat fee, then put the balance to work in Yield Mode. Top up, then swap your USDC into BTC, ETH, SOL, or any other supported asset.
