Functions 8

func Approve

Action 
1func Approve(_ int, rlm realm, tokenKey string, spender address, amount int64)
source

Approve sets an allowance owned by the CALLING REALM, letting `spender` draw on the calling realm's balance. It does not touch the signing user's allowances.

func Register

crossing Action 
1func Register(cur realm, token *grc20.Token, slug string) string
source

Register records token under its rlmPath.symbol key and returns that key. Token.ID() carries a trailing sequence id (rlmPath.symbol.<id>) that keeps token identities/events unique, but the registry deliberately keys by rlmPath.symbol so lookups don't need to know the id, and so a realm cannot register two tokens under the same symbol (overwrite/alias guard).

func Transfer

Action 
1func Transfer(_ int, rlm realm, tokenKey string, to address, amount int64)
source

Transfer moves `amount` out of the CALLING REALM's own balance.

Call it non-crossing, forwarding your own `cur`:

Example
1grc20reg.Transfer(0, cur, "gno.land/r/demo/defi/foo20.FOO", to, 100)

func TransferFrom

Action 
1func TransferFrom(_ int, rlm realm, tokenKey string, from, to address, amount int64)
source

TransferFrom spends an allowance with the CALLING REALM as the spender.

Note the allowance direction this implies: `from` must have approved the calling realm, not the signing user. That is the supported way for a realm to move a user's funds — the user grants the realm an allowance, and the realm draws on it as itself, so every debit is one the owner authorized against that specific realm.
