Transaction Types
Transaction Types on Shardeum
Shardeum uses different transaction types for various operations in the network. Understanding these transaction types is essential for developers working with the Shardeum blockchain.
1. EVM Transactions
These are standard Ethereum-style transactions that can be:
- Regular token transfers
- Smart contract deployments
- Smart contract interactions
These transactions are handled through:
2. Internal Transaction Types
Internal transactions are special system-level operations that manage the network's infrastructure, configuration, and staking mechanisms. They're defined in InternalTXType enum:
| Code | Transaction Type | Description |
|---|---|---|
| 1 | InitNetwork | Initializes the network with basic parameters |
| 2 | NodeReward | Deprecated - Previously used for node rewards |
| 3 | ChangeConfig | Proposes configuration changes to the network |
| 4 | ApplyChangeConfig | Applies previously proposed configuration changes |
| 5 | SetCertTime | Sets certification time for network nodes |
| 6 | Stake | Stakes tokens to participate in network validation |
| 7 | Unstake | Withdraws staked tokens from the network |
| 8 | InitRewardTimes | Initializes the reward distribution schedule |
| 9 | ClaimReward | Claims earned rewards by validators or participants |
| 10 | ChangeNetworkParam | Proposes changes to network parameters |
| 11 | ApplyNetworkParam | Applies previously proposed network parameter changes |
| 12 | Penalty | Applies penalties to misbehaving nodes |
| 13 | TransferFromSecureAccount | Transfers tokens from secure system accounts |
Debug Transaction Types
Debug transactions are special transactions (DebugTx) used for testing and debugging purposes, defined in DebugTXType enum:
| Code | Transaction Type | Description |
|---|---|---|
| 0 | create | Creates new accounts or contracts |
| 1 | transfer | Transfers tokens between accounts |
Transaction Validation
- EVM transactions are validated for chainId and proper formatting
- Internal transactions require proper signatures and permissions
- Debug transactions are only allowed when
debugTxEnabledflag is set - Staking transactions have additional validation for minimum stake amounts and ticket types
Each transaction type serves a specific purpose in the Shardeum network, from regular value transfers to network governance and validation.
