Fuel Network Beta 5

In Fuel Squid SDK, Fuel testnet and beta 5 data require different package versions. To work with Fuel beta 5, you need to set the following versions in your package.json:

{
  "dependencies": {
    "@subsquid/fuel-objects": "0.0.3",
    "@subsquid/fuel-stream": "0.0.3"
  }
}

and run:

rm -rf package-lock.json node_modules
npm i

Data sources​

To access beta 5 data, you need to set the gateway URL as follows:

const dataSource = new DataSourceBuilder()
  .setGateway("https://v2.archive.subsquid.io/network/fuel-stage-5");

You may also want to use a Beta 5 GraphQL endpoint for real-time data:

dataSource.setGraphql({
  url: 'https://beta-5.fuel.network/graphql'
})

Data requests​

Data requests are the same as they are in the testnet version:

Field Selection​

For Fuel DataSource the top-level Block interface is defined the same as in the testnet version.

Here are the differences in Beta 5 data structures, compared to Testnet:

  • In Transaction fields:

    • there are fewer transaction types: 'Script' | 'Create' | 'Mint'
    • mintGasPrice, isUpgrade, isUpload, bytecodeRoot, subsectionIndex, subsectionsNumber, proofSet, upgradePurpose fields are missing
    • gasPrice?: bigint and bytecodeLength?: bigint fields are added
    • inputContract.contractId subfield is called inputContract.contract
    • interface Policies lacks the tip field, but has an extra gasPrice?: bigint field
    • interfaces SuccessStatus and FailureStatus lack totalGas and totalFee fields

  • In Input fields:

    • InputCoin type has an added maturity: number field
    • InputContract type field contractId is called contract

  • In Output fields:

    • ContractCreated type's contract field instead of a string contains an object:
    contract: {
      id: Bytes
      bytecode: Bytes
      salt: Bytes
    }

  • In BlockHeader fields:

    • eventInboxRoot, consensusParametersVersion, stateTransitionBytecodeVersion and messageOutboxRoot fields are missing
    • transactionsCount and messageReceiptCount have type bigint instead of number
    • messageReceiptRoot: string field is added
