Function getRegistrationJustification

getRegistrationJustification<chain extends undefined | Chain>(
client: Client<Transport, chain>,
params: GetRegistrationJustificationParams,
): Promise<GetRegistrationJustificationReturnType>

Retrieves the registration justification for the given validation ID Hex and subnet ID.

If the validation ID corresponds to a bootstrap validator, the justification bytes produced by ConvertSubnetToL1Tx are returned.

Otherwise, the function searches the Warp logs on the chain where the validator manager is deployed to locate the RegisterL1ValidatorMessage for the specified validation ID.

Type Parameters

chain extends undefined | Chain

Parameters

client: Client<Transport, chain>
The AvalancheCoreClient instance.
params: GetRegistrationJustificationParams
The GetRegistrationJustificationParams instance.

Returns Promise<GetRegistrationJustificationReturnType>

The GetRegistrationJustificationReturnType instance.
