const { execute, loading, error } = useUpdateProfileManagers();
Enable/disable the Lens Profile Manager. This allows to perform signless transaction through the Lens API.
const { execute, loading, error } = useUpdateProfileManagers();
const callback = async () => {
const result = await execute({
approveSignless: true, // or false to disable it
});
if (result.isFailure()) {
toast.error(result.error.message);
}
};
Add/remove an arbitrary address to the list of Profile managers for the authenticated Profile.
const { execute, loading, error } = useUpdateProfileManagers();
const callback = async () => {
const result = await execute({
add: ['0x1234567890123456789012345678901234567890', '0x1234567890123456789012345678901234567891'],
remove: ['0x1234567890123456789012345678901234567892'],
});
}
You can handle possible failure scenarios by checking the result
value.
const callback = async () => {
const result = await execute({
approveSignless: true,
});
if (result.isFailure()) {
switch (result.error.name) {
case 'BroadcastingError':
console.log('There was an error broadcasting the transaction', error.message);
break;
case 'PendingSigningRequestError':
console.log(
'There is a pending signing request in your wallet. ' +
'Approve it or discard it and try again.'
);
break;
case 'WalletConnectionError':
console.log('There was an error connecting to your wallet', error.message);
break;
case 'UserRejectedError':
// the user decided to not sign, usually this is silently ignored by UIs
break;
}
return;
}
};
It just takes a single parameter to disable the sponsorship of the transaction gas costs.
const callback = async () => {
const result = await execute({
approveSignless: true,
sponsored: false, <-- this is the only change
});
if (result.isFailure()) {
switch (result.error.name) {
case 'InsufficientGasError':
console.log('You do not have enough funds to pay for the transaction gas cost.');
break;
// ...
}
return;
}
In this example you can also see a new error type: InsufficientGasError. This error happens only with self-funded transactions and it means that the wallet does not have enough funds to pay for the transaction gas costs.
If for some reason the Lens API cannot sponsor the transaction, the hook will fail with a BroadcastingError with one of the following reasons:
In those cases you can retry the transaction as self-funded like in the following example:
const callback = async () => {
// sponsored attempt
const sponsoredResult = await execute({
approveSignless: true,
});
if (sponsoredResult.isFailure()) {
switch (sponsoredResult.error.name) {
case 'BroadcastingError':
if ([BroadcastingErrorReason.NOT_SPONSORED, BroadcastingErrorReason.RATE_LIMITED].includes(sponsoredResult.error.reason)) {
const selfFundedResult = await execute({
approveSignless: true,
sponsored: false
});
// continue with selfFundedResult as in the previous example
}
break;
// ...
}
}
In this example we omitted BroadcastingErrorReason.APP_NOT_ALLOWED as it's not normally a problem per-se. It just requires the app to apply for whitelisting. See https://docs.lens.xyz/docs/gasless-and-signless#whitelisting-your-app.
You can still include it in your fallback logic if you want to. For example to unblock testing your app from a domain that is not the whitelisted one (e.g. localhost).
Update the profile manager configuration for the authenticated profile.
You MUST be authenticated via useLogin to use this hook.
NOTE This hook waits for the transaction to be mined and indexed before returning. This is due to the fact that until a Profile Manager configuration change is fully finalized, the enabled managers cannot yet sign transactions. In the case of disabling profile managers, it's very likely you'll want the rest of the application to not perform operations while the transaction is pending.
