Price versus payable amount
A 10.00 USDT product may have a 10.001 USDT payable amount. This is an illustration, not a fixed increment.
Integration guide
Why the payable amount has extra decimals
Small decimal offsets can distinguish orders sharing a wallet. Display the full API-returned payable amount; it may differ slightly from the product price.
Steps to follow
Exact amount matching flow
Best for merchants and developers designing USDT / USDC checkout flows where many customers pay into the same settlement wallet.
01 Create an order and save the full API-returned payable amount.
02 Display all decimal digits without rounding.
03 Free accounts use 3-digit precision; active members can select 2–6 for new orders.
04 Normalize chain amounts using actual token decimals and check all matching rules.
BoltUtil checks payments and sends signed callbacks. Your server verifies signatures and order status, deduplicates events, then delivers goods, activates service or credits accounts.
Integration notes
What matters before production
Order precision is not token decimals
Free accounts use the default 3-digit order precision. Active members can select 2–6 digits for new orders; existing orders retain their amounts. Read on-chain amounts using the configured token decimals.
Review differences through the permitted workflow
Qualifying manual transfers can create review records; verify ownership when several orders are candidates. Free merchants can view their own records; accepting or rejecting an association requires active membership. Acceptance confirms payment and triggers the configured callback. Do not fulfill from a screenshot or an approximate amount.
Product price: 10.00 USDT
Order A: 10.001 USDT
Order B: 10.002 USDT

Questions merchants ask before going live
Is the decimal offset a transaction fee?
No. It distinguishes orders sharing a wallet. Display the API-returned payable amount and do not label the offset as a BoltUtil transaction fee.
Which precision can I choose?
Free accounts use the default 3-digit order precision. Active members can select 2–6 digits for new orders; existing orders retain their amounts. Read on-chain amounts using the configured token decimals.
Can a successful transfer alone complete an order?
No. Check the configured network and token, destination, payable amount, order window and confirmation progress. Verify callbacks and fulfill only once.
Do all six networks support both currencies?
TRON supports USDT only. Available USDT / USDC pairs on other networks depend on enabled channels and configured wallets. Compare the configured contract or mint, not just the token name.
