 - `yarn ts-node tools/deploy-contract.ts` creates a new ANT with arweave data pointer. Requires a short token ticker, a friendly token name and an Arweave Transaction ID as the data pointer. The state variables can be updated in `initial-state.json` in the root folder of the project.
 - `yarn ts-node tools/remove-record` removes an existing subdomain from the ANT. Requires the subdomain name to be removed and the ANT Smartweave Contract ID.
-- `yarn ts-node tools/transfer` transfers a ANT to another wallet. Requires the recipient target to transfer the ANT to, and the ANT Smartweave Contract ID that is to be transferred.

 - `yarn ts-node tools/set-controller` - adds a controller to the record. Requires the ANT Smartweave Contract ID and the target address to add as a controller. Controllers have the ability to update the ANT records.
 - `yarn ts-node tools/set-record` - sets a record for a given subdomain. Requires the subdomain name that is to be created or updated, the ANT Smartweave Contract ID and an Arweave Transaction. '@' records are used to set the root record. Other records are resolved as undernames (e.g. a record of `subdomain` with the root name as `arns` on the ArNS Registry Contract will resolve as `subdomain_arns.arweave.dev`)
