Request

Header Params

Body Params application/json
eip712Message
string 
required
Encoded JSON string containing the message details in EIP-712 format, which includes:
account: Sender's account address.
domain: Contains metadata such as chainId and application name(Vessel) for the signing context.
message: Message details with the following:
action: Specifies the operation as "Send".
fromAddress: Address of the sender.
toAddress: Address of the recipient.
assetID: ID of the asset being transferred.
sendAmount: Amount to send.
feeAmount: Associated fee (if any). Currently, the fee is 0.

eip712Signature
string 
required
Signature of the eip712Message in EIP-712 format. Confirm that all addresses, especially those under fields like "account", "fromAddress", and "toAddress", are in lowercase. EIP-712 requires address consistency, and using lowercase avoids discrepancies.
