Seguro que muchas veces te has preguntado como quitar o como hacer «dissaprove» a un contrato con un token en la red BSC.
Lo primero de todo tranquilizaros. Un contrato con un token scam no os va a vaciar la cartera, cuando aprobamos esa operación, aprobamos el gasto en ese token, no le damos acceso a ningún otro.
Si aprobamos las operaciones con el token que creó Manolo en el sótano y resulta ser scam, no puede vaciarnos la cartera, si eso fuese posible, ninguno de nosotros tendríamos un solo céntimo en nuestra wallet.
Pero igualmente o explicaré como se hace, en este caso utilizaré metamask, que es lo habitual cuando tradeamos en pancakeswap o similares (donde está el riesgo real de scam, posibles gemas, pero también mucha basura).

Comencemos el proceso de dissaprove de un contrato en la binance smart chain con metamask.
Lo primero que debemos hacer es ir a este link https://bscscan.com/tokenapprovalchecker
Para llegar a ese link debemos entrar en BSCSCAN - MORE - TOOLS - TOKEN APPROVALS. Adjunto captura de pantalla
Una vez ahí nos saldrá un recuadro para poner la dirección de nuestra wallet, la ponemos. Nos saldrán todos los tokens que tenemos aprobados, os adjunto una imagen de mi cartera como ejemplo.
Realmente de esos tokens solamente utilizo Bomber Coin, el otro fueron tokens que utilicé en su día para jugar (DrakeBall) o para tradear y no sé que ocurrió con ellos, supongo que se habrán ido al pozo ya. Pero como veis no los quito porque no representan ningún problema para mi cartera.
El siguiente paso es darle al botón azul que aparece a la derecha de todo en cada token aprobado, pero no te dejará, tendrás que acceder con tu cartera a la bscscan (el «desvincular» es una operación por la que hay que pagar gas).
Para ello, en la parte superior tenemos un botón para acceder, es este:
En cuanto le demos nos saldrá la opción de Metamask o la de Wallet Connect.
En este caso como lo estamos haciendo con metamask, simplemente seleccionamos, aceptamos y listo.
Ahora ya podremos interactuar con los botones azules. Si le damos a uno de ellos nos saldrá un menú en la pantalla llamado «Revoke Approval». Os lo muestro
Una vez nos salga eso, ya estaremos en el tramo final. Ahora lo siguiente será darle click en «Revoke» y nos abrirá una pestaña de metamask para pagar el gas fee.
A mi me suele salir para esto una tarifa fija de 0.12$. Aceptaremos y listo, le habremos quitado los permisos que tenía a ese contrato.
Espero que os haya sido útil.
