Fee
Paid by the sender to the FeeSink to prevent denial-of-service. The minimum fee on Algorand is currently 1000 microAlgos.
First Valid
The first round for when the transaction is valid. If the transaction is sent prior to this round it will be rejected by the network.
OptionalgenGenesis ID
The human-readable string that identifies the network for the transaction. The genesis ID is found in the genesis block. See the genesis ID for MainNet, TestNet, and BetaNet.
Genesis Hash
The hash of the genesis block of the network for which the transaction is valid. See the genesis hash for MainNet, TestNet, and BetaNet.
OptionalgrpGroup
The group specifies that the transaction is part of a group and, if so, specifies the hash of the transaction group. Assign a group ID to a transaction through the workflow described in the Atomic Transfers Guide.
Last Valid
The ending round for which the transaction is valid. After this round, the transaction will be rejected by the network.
OptionallxLease
A lease enforces mutual exclusion of transactions. If this field is nonzero, then once the transaction is confirmed, it acquires the lease identified by the (Sender, Lease) pair of the transaction until the LastValid round passes. While this transaction possesses the lease, no other transaction specifying this lease can be confirmed. A lease is often used in the context of Algorand Smart Contracts to prevent replay attacks. Read more about Algorand Smart Contracts. Leases can also be used to safeguard against unintended duplicate spends. For example, if I send a transaction to the network and later realize my fee was too low, I could send another transaction with a higher fee, but the same lease value. This would ensure that only one of those transactions ends up getting confirmed during the validity period.
OptionalnonpartNonparticipating
All new Algorand accounts are participating by default. This means that they earn rewards. Mark an account nonparticipating by setting this value to true and this account will no longer earn rewards. It is unlikely that you will ever need to do this and exists mainly for economic-related functions on the network.
OptionalnoteNote
Any data up to 1000 bytes.
OptionalrekeyRekey To
Specifies the authorized address. This address will be used to authorize all future transactions.
OptionalselkeySelection PublicKey
The VRF public key.
Sender
The address of the account that pays the fee and amount.
OptionalsprfkeyState Proof PublicKey
The 64 byte state proof public key commitment.
Transaction Type
Specifies the type of transaction. This value is automatically generated using any of the developer tools.
OptionalvotefstVote First
The first round that the participation key is valid. Not to be confused with the FirstValid round of the keyreg transaction.
OptionalvotekdVote Key Dilution
This is the dilution for the 2-level participation key. It determines the interval (number of rounds) for generating new ephemeral keys.
OptionalvotekeyVote PublicKey
The root participation public key.
OptionalvotelstVote Last
The last round that the participation key is valid. Not to be confused with the LastValid round of the keyreg transaction.
