Token Contracts
The technical notebook behind the scenes of "Crypto Transaction": every token has a "smart contract address" on every network (for example, USDT has one address on TRC20 and a different one on ERC20). When looking up a transaction, the system identifies the token and its decimal count from this very table.
Fields
| Field | Description |
|---|---|
| Currency | The token the contract belongs to (must already exist in "Currencies"). |
| Network | The relevant blockchain. |
| Contract address | The token's smart contract address on that network. |
| Decimals | The token's decimal count on-chain. |
Notes
- Copy the contract address from an official explorer (e.g., Tronscan); a single wrong character means the token won't be recognized.
Allowed currencies and the official reference
At the top you pick the "currencies allowed for transaction recognition" (default: Tether only): lookups for any other token — even with a registered contract — are rejected with a serious warning, so unexpected or fake tokens never enter your books. The "official contract reference" works like the website tool: pick a currency and network (TRON, Ethereum, BSC, Polygon, Solana), see the official address and add it to your book with one click. Auto lookup works on TRON, Ethereum, BSC and Polygon; Solana is book-only for now.
