# Transaction Management

**Broadcast / Transaction Transmission API:** <https://bc.ggez.one:8443/broadcast_tx_asyn>

**Transaction Fee Calculation:** tx\_fee= gas\_limit\* gas\_price

**Conversion Rate of Transaction Units with the Main Unit:**\
1 GGEZ1 = 1,000 MGGEZ = 1,000,000 UGGEZ1

**Transaction Success Validation Criteria:**\
Based on Response Code, if code is 0 then transaction is successful.

**Memo/Tag Support:** Yes

## Send Token Example

Send token using Keplr wallet.

**@cosmjs/stargate** and **@keplr-wallet/types** packages required to complete transaction.\
Also **chain info** file:\
<https://github.com/chainapsis/keplr-chain-registry/blob/main/cosmos/ggezchain.json>
