# Variable: MULTICALL_CONTRACT_ID

# Variable: MULTICALL\_CONTRACT\_ID

> `const` **MULTICALL\_CONTRACT\_ID**: `Record`\<[`Network`](/sdk-reference/nextjs/src/type-aliases/Network), `string`>

Defined in: [packages/accounts/src/batch/multicall-pin.ts:16](https://github.com/bucks-pay/buckspay-sdk/blob/43ad599d2776cb5d657043c36847b3318093ccf4/packages/accounts/src/batch/multicall-pin.ts#L16)

Pinned Multicall router C-address per network. The Multicall contract is sponsored-installed
once per network (hash-pinned `97b8f81a...`, like the OZ smart-account + FeeForwarder wasm) and
its `batch_transfer(payer, token, Vec<(to, amount)>)` entrypoint settles an atomic batch.

* testnet: deployed and verified on-chain - the Multicall router is live.
* pubnet:  empty until the facilitator deploys + pins it - a pubnet batch then
  fails closed with INVALID\_CONFIG rather than using a wrong/testnet router.

A caller may override per-call via `ozContractAccount({ multicallContract })` /
`classicAccount({ multicallContract })`. No `process.env` read (the SDK runs in browsers).
