A method of preventing an erroneous deposit of cryptocurrency includes providing an interface for inputting transaction request information including a target coin and a wallet address; verifying at least one of the target coin and the wallet address using a trading environment of a target exchange corresponding to the transaction request information; and processing a transaction according to the transaction request information based on a verification result. ## Claims ### Claim 1 A method of preventing an erroneous deposit of cryptocurrency executed by a computer device comprising at least one processor configured to execute computer-readable instructions included in a memory, the method comprising: providing an interface for inputting transaction request information including a target coin and a wallet address; verifying at least one of the target coin and the wallet address using a trading environment of a target exchange corresponding to the transaction request information; and processing a transaction according to the transaction request information based on a result of verifying the at least one of the target coin and the wallet address, wherein the providing of the interface for inputting the transaction request information comprises providing an interface for a user confirmation for the target coin in response to the target coin being input through the interface. ### Claim 2 (depends on 1) The method of claim 1, wherein the verifying comprises verifying the wallet address by verifying an address belonging to the target exchange. ### Claim 3 (depends on 1) The method of claim 1, wherein the verifying comprises verifying the target coin by verifying a coin type tradable in the target exchange. ### Claim 4 (depends on 1) The method of claim 1, wherein the verifying comprises verifying the wallet address by verifying a network type processible in the target exchange. ### Claim 5 (depends on 1) The method of claim 1, wherein the verifying comprises verifying the wallet address by verifying an address registered as an erroneous deposit damage case. ### Claim 6 (depends on 1) The method of claim 1, wherein the verifying comprises verifying the trading environment of the target exchange through a database system included in the computer device, another external system interactable with the computer device, or an exchange application program interface (API). ### Claim 7 (depends on 1) The method of claim 1, wherein the processing comprises: performing a primary remittance for a portion of a transaction request quantity; and performing an additional remittance for a remaining quantity of the transaction request quantity in response to the primary remittance being authorized. ### Claim 8 (depends on 7) The method of claim 7, wherein the performing of the primary remittance comprises remitting a quantity corresponding to a singular value that is randomly determined for the transaction request information, and the performing of the additional remittance comprises remitting the remaining quantity in response to a success in authorization using the singular value. ### Claim 9 (depends on 7) The method of claim 7, wherein the performing of the additional remittance comprises remitting the remaining quantity in response to a success in authorization using a transaction ID that represents a transaction of the primary remittance. ### Claim 10 (depends on 1) The method of claim 1, wherein the providing comprises recommending a list of addresses managed using an alias on an interface for inputting the wallet address. ### Claim 11 (depends on 1) The method of claim 1, wherein the providing comprises recommending a list of addresses based on a user transaction history on an interface for inputting the wallet address. ### Claim 12 (depends on 1) The method of claim 1, wherein the providing comprises recommending an address system of the target coin or the target exchange on an interface for inputting the wallet address in response to the target coin or the target exchange being input first. ### Claim 13 (depends on 1) The method of claim 1, wherein the providing comprises recommending a list of exchanges that trade the target coin on an interface for inputting the target exchange in response to the target coin being input first. ### Claim 14 (depends on 1) The method of claim 1, wherein the providing comprises recommending a list of coins tradable in the target exchange on an interface for inputting the target coin, in response to the target exchange being input first. ### Claim 15 (depends on 1) The method of claim 1, wherein the providing comprises displaying a watermark on information input through the interface as a background of the interface. ### Claim 16 A non-transitory computer-readable recording medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method of preventing an erroneous deposit of cryptocurrency, the method comprising: providing an interface for inputting transaction request information including a target coin and a wallet address; verifying at least one of the target coin and the wallet address using a trading environment of a target exchange corresponding to the transaction request information; and processing a transaction according to the transaction request information based on a result of verifying the at least one of the target coin and the wallet address, wherein the providing of the interface for inputting the transaction request information comprises providing an interface for a user confirmation for the target coin in response to the target coin being input through the interface. ### Claim 17 A computer device comprising: at least one memory storing computer-readable instructions; and at least one processor configured to execute the computer-readable instructions to: provide an interface for inputting transaction request information including a target coin and a wallet address; verify at least one of the target coin and the wallet address using a trading environment of a target exchange corresponding to the transaction request information; and process a transaction according to the transaction request information based on a result of verifying the at least one of the target coin and the wallet address, wherein to provide the interface for inputting the transaction request information comprises to provide an interface for a user confirmation for the target coin in response to the target coin being input through the interface. ### Claim 18 (depends on 17) The computer device of claim 17, wherein the at least one processor is further configured to verify the target coin by verifying a coin type tradable in the target exchange, or to verify the wallet address by verifying at least one of an address belonging to the target exchange and a network type processible in the target exchange. ### Claim 19 (depends on 17) The computer device of claim 17, wherein the at least one processor is further configured to perform a primary remittance for a portion of a transaction request quantity, and to perform an additional remittance for a remaining quantity of the transaction request quantity through authorization for the primary remittance.
