SmartWeave Global API

All contracts have access to a global object SmartWeave. It provides access to additional API for getting further information or using utility and crypto functions from inside the contract execution. It also allows to interact with other contracts and read other contracts states.

List of available options:

JavaScript​

  • current transaction data:

    • SmartWeave.transaction.id
    • SmartWeave.transaction.owner
    • SmartWeave.transaction.tags (tags are already decoded)
    • SmartWeave.transaction.quantity
    • SmartWeave.transaction.target
    • SmartWeave.transaction.reward

  • contract

    • SmartWeave.contract.id
    • SmartWeave.contract.owner

  • contracts

    • SmartWeave.contracts.readContractState(contractId: string)
    • SmartWeave.contracts.viewContractState(contractId: string, input: any)
    • SmartWeave.contracts.write(contractId: string, input: any)

  • current block data:

    • SmartWeave.block.height
    • SmartWeave.block.timestamp
    • SmartWeave.block.indep_hash

  • Arweave utils

    • SmartWeave.arweave.utils
    • SmartWeave.arweave.crypto
    • SmartWeave.arweave.wallets

    • SmartWeave.evaluationOptions

  • VRF

    • SmartWeave.vrf.data
    • SmartWeave.vrf.value
