Accept Hamster Kombat (HMSTR) payments
HMSTR is the token of the Telegram game Hamster Kombat, issued as a jetton on TON, and a large number of Telegram users hold it. easyway accepts it next to Gram and the other TON jettons, on the same checkout, payment links and API. Below: which HMSTR counts, what paying looks like for the customer, and what holding a non-stable token means for you.
Token, network and limits
| Token | Network | Master contract | Confirmations | Min. withdrawal | Withdrawal fee |
|---|---|---|---|---|---|
| Hamster Kombat (HMSTR) | TON · Jetton | EQAJ8uWd7EBqsmpSWaRdf_I-8R8-XHwh3gsNKhy-UrdrPcUo | 1 | 3500 HMSTR | 1300 HMSTR (flat) |
This is the master contract that TON explorers list as the verified HMSTR jetton. Only transfers of exactly this jetton are credited; a look-alike token called "HMSTR" from another contract is ignored. Customers withdrawing from an exchange should pick the TON network there.
What paying looks like for the customer
On TON, every invoice is paid to one shared address and told apart by a numeric memo (comment). The checkout shows the address, the exact HMSTR amount and the memo, plus a QR code with a ton://transfer/… link that fills in all three and picks the HMSTR jetton, so a customer who scans it cannot forget the memo. The transfer needs a little Gram for the network fee, which the customer's wallet pays.
HMSTR was airdropped as a mintless jetton: a holder who has never moved their airdrop sends a proof with their first transfer that claims it, and wallets that support mintless jettons add that proof on their own. If a customer's wallet shows an HMSTR balance it cannot send, they need a wallet that supports mintless jettons. Nothing changes for you: the invoice receives an ordinary HMSTR transfer.
A payment is credited only when two independent TON indexers both report the same amount, jetton and memo as a finished, successful transfer — that defeats forged jetton notifications. TON blocks are final, so this takes seconds. Transfers below 70 HMSTR (about a cent) are skipped as spam. Late and short payments follow the underpaid and late payments guide.
Price risk and fees
HMSTR's price moves. For a USD invoice the HMSTR amount is locked from the exchange rate when the customer chooses the coin; after the payment, HMSTR is credited and withdrawn as HMSTR, so later price moves are yours. Pricing an invoice in HMSTR itself (currency = "HMSTR_TON") skips the conversion.
The platform fee is a flat 0.5% of each confirmed payment — 100,000 HMSTR paid leaves 99,500 HMSTR on your balance. The withdrawal fee and minimum above are fixed HMSTR amounts sized for the Gram a jetton transfer carries for gas at listing time, so their dollar value follows HMSTR's price. If you would rather end up with dollars, also offer USDT on TON and choose per invoice with allowed_assets. All coins are on the pricing page.
Integrating
Nothing is HMSTR-specific: create an invoice through the API (or a payment link without code), redirect to the hosted checkout, and fulfil on the signed invoice.paid webhook. The quickstart has runnable examples, and the sandbox guide shows how to try the flow without real funds.
Common questions
Who holds the HMSTR? easyway keeps it on your balance until you withdraw. Live withdrawals go only to addresses you have whitelisted with two-factor authentication, with an optional memo for exchange deposit addresses; see security.
Which other TON coins are accepted? Gram itself, Notcoin, DOGS and Catizen (see Gram and TON jettons) and USDT on TON, all on the same address and memo flow.
