semaphore:create-group

Create a Semaphore group on the canonical contract and bind the predicted group id to . Without --admin the transaction sender becomes the admin (correct through Safes and forwarders).

⚗️ Experimental — available at next.evmcrispr.com.

Syntax

semaphore:create-group <variable>

Arguments

Name	Type	Description
variable	variable	Variable to bind the new group id to

Options

Name	Type	Description
--admin	address	Group admin (default: the transaction sender)

Notes

• The group id is predicted from groupCounter at planning time — an external group creation landing before your transaction shifts it (the same character as contracts:deploy address prediction).
• Creating a group also primes the member cache, so later member scans only cover blocks after creation.

Examples

load semaphore
semaphore:create-group $group
semaphore:add-member $membercommitment to $group
print "Created group" $group "with root" @semaphore:root($group)
