Claimable EOSIO token to recover RAM quickly. Also allows you to change issuer and max supply.
Added to the balance table is the claimed boolean flag.
When the token is issued claimed = false and the RAM is paid by the issuer.
When the token is transferred the balance row is dropped and re-added using the RAM of the owner.
Tokens can also be explicitly claimed using the claim action, if the owner doesn't want to transfer.
In theory, unclaimed tokens can be recovered after some claiming period to have guaranteed RAM recovery.
- update
This action uses the same ABI as create and allows you to change the issuer and/or max supply of a token
Only the token contract itself can authorize this action, not the previous issuer
cleos push action claimable.token update '{"issuer":"newissuer","maximum_supply":"100000.0000 TOK"}'
- claim
This action allows a token balance owner to claim their token without transferring it
This is only really neccessary if the token contract will recover unclaimed Tokens
cleos push action claimable.token claim '{"owner":"user1","sym":"4,TOK"}'
- recover
This action allows the token contract to recover unclaimed tokens, thus freeing RAM
The unclaimed tokens are added to the current issuer balance
This command only does something if the balance is truly unclaimed, otherwise it does nothing
cleos push action claimable.token recover '{"owner":"user1","sym":"4,TOK"}'
