Multiquery

On-chain query aggregator/batcher in Terra.

---

Deployments can be found in state.json. To use this in a Typescript project, you can use @abstract-money/cosmwasm-utils package with the MultiQueryCosmWasmClient class (source). This will take all smart-queries sent through the client and batch them to lessen the load on the RPC endpoints.

Example Usage

Example Query: Link

const multicallRes: any = await terra.wasm.contractQuery(multiquery, {
  aggregate: {
    queries: [
      {
        address: "terra15dwd5mj8v59wpj0wvt23mf5efdff808c5tkal",
        data: toBase64({ config: {} }),
      },
      {
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ epoch_state: {} }),
      },
    ],
  },
})

console.log(multicallRes)

// ---
{
  return_data: [
    {
      success: true,

const decoded = multicallRes.return_data.map((e) => {
  return JSON.parse(Buffer.from(e.data, "base64").toString())
})

Try Aggregate

Aggregate with error suppression variant. If include_cause is true, data of the query will be error message in String if that query is return error. Else will return empty string.

Example Query: Link

const multicallRes: any = await terra.wasm.contractQuery(multiquery, {
  try_aggregate: {
    require_success: false, // defualt to false
    include_cause: true, // default to false
    queries: [
      {
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ config: {} }),
      },
      {
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ epoch_state: {} }),
      },
    ],
  },
})

const decoded = multicallRes.return_data.map((e) => {
  return e.length == 0
    ? null
    : JSON.parse(Buffer.from(e.data, "base64").toString())
})

Try Aggregate With Optional Require Success

Aggregate with specific error suppression variant. Same as try_aggregate but with element-specific error handling.

Example Query: Link

const multicallRes: any = await terra.wasm.contractQuery(multiquery, {
  try_aggregate_optional: {
    include_cause: true, // default to false
    queries: []]]]
      {
        require_success: true,
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ config: {} })
      },
      {
        require_success: false,
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ epoch_state: {} })
      },
    ]
  }
})

const decoded = multicallRes.return_data.map((e) => {
  return e.length == 0 ? null : JSON.parse(Buffer.from(e.data, 'base64').toString())
})

Aggregate With Block

Include block_ as prefix for query message to include block height as a result.

Example Query: Link

const multicallRes: any = await terra.wasm.contractQuery(multiquery, {
  block_aggregate: {
    queries: [
      {
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ config: {} })
      },
      {
        address: "terra15dwd5mj8v59wpj0wvt233mf5efdff808c5tkal",
        data: toBase64({ epoch_state: {} })
      },
    ]
  }
})

console.log(multicallRes)
