It'd be great to have this overridable by env var, such as in https://github.com/LayerZero-Labs/devtools/blob/main/packages/devtools/src/transactions/signer.ts#L180-L183.

I agree, this should be configurable via env vars must be the easiest way


const chunkArray = <T>(array: T[], size: number): T[][] => {
const chunks: T[][] = []
for (let i = 0; i < array.length; i += size) {
chunks.push(array.slice(i, i + size))
}
return chunks
}
