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.

Abstract: Implementations are directed to receiving, by a trusted signing service that is executed in an off-chain network, a user operation, signing, by the trusted signing service, the user operation to provide a signed user operation, receiving, by a paymaster that is executed in a chain network, a call to verify, the call including at least a signature of the signed user operation, and in response to determining that the signature of the signed user operation is valid, providing, by the paymaster and to an entrypoint that is executed in the chain network, a response to the call indicating that the paymaster is verified, the user operation being executed in the chain network at least partially in response to determining that the signature of the signed user operation is valid.

Abstract: Certain aspects of the disclosure provide a method for leasing a blockchain address, including receiving a first lease request for a blockchain address configured to receive a blockchain transaction on behalf of a user. The method further includes determining lease states for a plurality of existing blockchain addresses in a blockchain address lease pool and based on the determined lease states, determining whether to lease an existing blockchain address from the blockchain address lease pool or to generate a new blockchain address for the blockchain address lease pool. The method further includes leasing a first blockchain address from the blockchain address lease pool to the first user.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for efficiently processing transactions on a blockchain. An example method generally includes receiving, at a relay service, a request to execute a transaction on a blockchain. Generally, the request includes a request to transfer a quantity of a first type of token on the blockchain from a transmitter wallet to a receiver wallet identified in the request and incurs a transaction overhead on the blockchain in a second type of token. The request is modified based on the quantity of the first type of token, the transaction overhead in the second type of token, and a policy defining a source from which the transaction overhead is to be retrieved. The transaction is executed on the blockchain based on the modified request without transferring the second type of token from the transmitter wallet to satisfy the transaction overhead.
