@ethereumjs/tx / TxOptions

Interface: TxOptions

Defined in: types.ts:57

The options for initializing a Transaction.

Properties

allowUnlimitedInitCodeSize?

optional allowUnlimitedInitCodeSize: boolean

Defined in: types.ts:103

Allows unlimited contract code-size init while debugging. This (partially) disables EIP-3860. Gas cost for initcode size analysis will still be charged. Use with caution.

---

common?

optional common: Common

Defined in: types.ts:68

A Common object defining the chain and hardfork for the transaction.

Object will be internally copied so that tx behavior don’t incidentally change on future HF changes.

Default: Common object set to mainnet and the default hardfork as defined in the Common class.

Current default hardfork: istanbul

---

freeze?

optional freeze: boolean

Defined in: types.ts:97

A transaction object by default gets frozen along initialization. This gives you strong additional security guarantees on the consistency of the tx parameters. It also enables tx hash caching when the hash() method is called multiple times.

If you need to deactivate the tx freeze - e.g. because you want to subclass tx and add additional properties - it is strongly encouraged that you do the freeze yourself within your code instead.

Default: true

params?

optional params: ParamsDict

Defined in: types.ts:85

Tx parameters sorted by EIP can be found in the exported paramsTx dictionary, which is internally passed to the associated @ethereumjs/common instance which manages parameter selection based on the hardfork and EIP settings.

This option allows providing a custom set of parameters. Note that parameters get fully overwritten, so you need to extend the default parameter dict to provide the full parameter set.

It is recommended to deep-clone the params object for this to avoid side effects:

const params = JSON.parse(JSON.stringify(paramsTx))
params['1']['txGas'] = 30000 // 21000
