How to accept WETH (Polygon)

  1. Create a WETH deposit address

    Send one request with the URL to notify and the EVM wallet that receives the money. The same callback URL always returns the same address.

    curl "https://api.trezorpay.com/polygon/weth/create/?callback=https://your.shop/paid?order=42&address=0x62f90a0Cde262228Afd74939E04d32E23Ec25677&pending=1"

  2. Show the address to your customer

    Display address_in, with a QR code from /polygon/weth/qrcode/ if you like. Your customer pays at least 0.0005 WETH; the address never expires and can be paid any number of times.

  3. Receive the funds and a signed callback

    After 64 confirmations (about 2 minutes), we forward the payment to your wallet and call your URL with pending=0, value_forwarded_coin, txid_out, coin=polygon_weth, signed in x-ca-signature. Answer *ok*.

WETH on Polygon

Polygon PoS has negligible gas costs and a fast block time; payments wait 64 blocks before forwarding to stay safe from reorganisations.

For a WETH token payment, we send the gas the transfer needs ourselves and charge its cost in WETH at the market price. Your wallet never needs native coin.

Prefer to see the numbers first? Try the simulator, or read how fees and callbacks work.

WETH (Polygon) payments: questions

What is the minimum WETH (Polygon) payment?

0.0005 WETH. A smaller payment is still recorded and shown in /logs/, but it is not forwarded, so that the network cost can never eat the payment.

How long until a WETH (Polygon) payment reaches my wallet?

We forward it once it has 64 confirmations on Polygon, which takes about 2 minutes on average, then send your server a signed callback with the forwarding transaction id.

Who pays the network fee for WETH (Polygon)?

We send the gas the token transfer needs and recover its cost in WETH at the market price, together with our 1.25% fee. You never need native coin in your wallet.

Do I need an account to accept WETH (Polygon)?

No. There is no sign-up and no API key: one request to /polygon/weth/create/ with your callback URL and your EVM wallet returns a deposit address. Funds go straight to that wallet.
