Cryptographic currency exchange
In some embodiments, in connection with an API request to transact with an entity, a first conversion rate associated with a first time may be determined, where the first conversion rate is a current conversion rate for an on-chain asset at the first time; Based on a monitoring of a blockchain, a receipt of the on-chain asset at a second blockchain address from a first blockchain address associated with the user may be detected on the blockchain. In response to the detection, the on-chain asset may be converted to an off-chain asset at a second time associated with a second conversion rate, the second conversion rate being the current conversion rate for the on-chain asset at the second time. An amount of the off-chain asset may be transmitted to the entity, where the amount of the off-chain asset sent to the entity is based on the first conversion rate.
