Abstract: A custodial token platform may implement smart contracts for inbound transactions and flush transactions. The platform may deploy to a blockchain ledger, a plurality of inbound smart contracts, including first inbound smart contract for a first user of a plurality of users of a custodial token platform. The plurality of smart contracts may include a second inbound smart contract for a second user of the plurality of users of the custodial token platform. The platform may deploy a batch smart contract configured to control the plurality of inbound smart contracts. The platform may broadcast a transaction that calls the batch smart contract. The transaction causes a transfer of the first set of one or more crypto tokens of the first inbound smart contract and the second set of one or more crypto tokens of the second inbound smart contract to an outbound address of the custodial token platform.

Abstract: To support token recovery at a token management system, a custodial token platform may receive via a user interface, an identifier of a first blockchain transaction that is associated with a crypto token that is not supported by the custodial token platform and that is to be recovered from an inbound address of the custodial token platform. Information associated with the first blockchain transaction may be displayed, and the user interface may receive an indication of a user address associated with a user and that is external to the custodial token platform. The custodial token platform may verify the user address using a signed message and may broadcast, subsequent to verifying that the message is signed, a second blockchain transaction configured to transfer the crypto token from the inbound address to the user address.
