Abstract: Certain aspects of the present disclosure provide techniques and apparatus for processing recoverable transactions on a blockchain. An example method generally includes receiving a request to execute a transaction on a blockchain to transfer a quantity of a wrapped token which encapsulates a base token exchanged in transactions on the blockchain. A running total of tokens in the receiver wallet that are in a recoverable state is incremented by the quantity of the token identified in the request. After a threshold amount of time from a timestamp associated with the received request, it is determined whether the transaction has been frozen. Based on determining that the transaction has not been frozen, the running total of tokens in the receiver wallet that are in the recoverable state is decremented, and a running total of tokens in the receiver wallet that are in a non-recoverable state is incremented.

Abstract: Certain aspects of the present disclosure provide techniques for performing a blockchain-based transaction, comprising: executing a first process on a first blockchain, including: causing a first amount of cryptocurrency to be burned on the first blockchain according to a burn operation; formatting a message to include one or more details of the burn operation; and emitting the message to an event log associated with the first blockchain; requesting an attestation from an attestation service based on a hash of the message emitted to the event log; receiving the attestation from the attestation service; and executing a second process on a second blockchain, including: providing the message and the attestation to the second blockchain; and causing a second amount of cryptocurrency to be minted on the second blockchain based on the message.

Abstract: Certain aspects of the present disclosure provide techniques for multi-blockchain token rebalancing. According to certain embodiments, a target ratio defining a first quantitative relationship between an amount of a token present is determined for each of a plurality of blockchains. A current amount of the token is received for a first blockchain, and in some embodiments, a first ratio is generated for the token present on each of the plurality of blockchains, based on the current amount. The current amount is compared to the target ratio to generate a ratio difference. Based on the ratio difference, a rebalancing transaction is executed on the first blockchain to bring the amount of the first token closer to the target ratio for the first blockchain.
